Thomas (Washburn University, Kansas), Adrian L. Melott (University of Kansas) Comments: 12 pages including 5 figures (4 in color). Submitted to New Journal of Physics for special issue "Focus on Gamma-Ray Bursts" We describe results of modeling the effects of gamma-ray bursts (GRBs) within a few kiloparsecs of an Earth-like planet. A primary effect is generation of nitrogen oxide compounds which deplete ozone. Ozone depletion leads to an increase in solar UVB radiation at the surface, enhancing DNA damage, particularly in marine microorganisms such as phytoplankton. In addition, we expect increased atmospheric opacity due to buildup of nitrogen dioxide produced by the burst and enhanced precipitation of nitric acid. We review here previous work on this subject and discuss recent developments. http://arxiv.org/abs/astro-ph/0601711 From owner-public@setileague.org Thu Feb 2 08:55:00 2006 X-Spam-Checker-Version: SpamAssassin 3.1.0 (2005-09-13) on Sentry.net X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=MSGID_FROM_MTA_HEADER autolearn=unavailable version=3.1.0 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id k12GsxgK031788 for ; Thu, 2 Feb 2006 08:55:00 -0800 Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id LAA08893 for public-list; Thu, 2 Feb 2006 11:47:02 -0500 (EST) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from hotmail.com (bay114-f2.bay114.hotmail.com [65.54.169.12]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id LAA08886; Thu, 2 Feb 2006 11:47:00 -0500 (EST) Received: from mail pickup service by hotmail.com with Microsoft SMTPSVC; Thu, 2 Feb 2006 08:46:28 -0800 Message-ID: Received: from 65.54.169.200 by by114fd.bay114.hotmail.msn.com with HTTP; Thu, 02 Feb 2006 16:46:27 GMT X-Originating-IP: [24.39.94.195] X-Originating-Email: [ljk4@msn.com] X-Sender: ljk4@msn.com From: "LARRY KLAES" To: public@setileague.org Cc: bioastro@setileague.org Subject: SETI public: FW: SETI Institute E-Newsletter February 2006 Date: Thu, 02 Feb 2006 11:46:27 -0500 Mime-Version: 1.0 Content-Type: text/plain; format=flowed X-OriginalArrivalTime: 02 Feb 2006 16:46:28.0717 (UTC) FILETIME=[369C31D0:01C62818] Sender: owner-public@setileague.org Precedence: bulk >From: "SETI Institute" >Reply-To: >Subject: SETI Institute E-Newsletter February 2006 >Date: Wed, 01 Feb 2006 15:21:14 -0800 > > > > > > > > > > > > > > > > > > > > > > >February 2006 > > > > > > >Welcome to the re-designed SETI Institute E-Newsletter!

Grindlay [view email] Date: Fri, 30 Dec 2005 20:24:37 GMT (37kb) Short gamma-ray bursts from binary neutron star mergers in globular clusters Authors: Jonathan Grindlay (1), Simon Portegies Zwart (2), Stephen McMillan (3) ((1) Harvard-Smithsonian Center for Astrophysics, (2) Astronomical Institute Anton Pannekoek, (3) Department of Physics, Drexel University) Comments: 13 pages, 2 figures, accepted for publication in Nature Physics (Feb. 2006) The first locations of short gamma-ray bursts (GRBs) in elliptical galaxies suggest they are produced by the mergers of double neutron star (DNS) binaries in old stellar populations. Globular clusters, where the extreme densities of very old stars in cluster cores create and exchange compact binaries efficiently, are a natural environment to produce merging NSs. They also allow some short GRBs to be offset from their host galaxies, as opposed to DNS systems formed from massive binary stars which appear to remain in galactic disks. Starting with a simple scaling from the first DNS observed in a galactic globular, which will produce a short GRB in ~300My, we present numerical simulations which show that ~10-30% of short GRBs may be produced in globular clusters vs. the much more numerous DNS mergers and short GRBs predicted for galactic disks. Reconciling the rates suggests the disk short GRBs are more beamed, perhaps by both the increased merger angular momentum from the DNS spin-orbit alignment (random for the DNS systems in globulars) and a larger magnetic field on the secondary NS. http://arxiv.org/abs/astro-ph/0512654 Release No.: 06-12 For Release: Tuesday, January 31, 2006 Note to editors: Images to accompany this release are online at http://www.cfa.harvard.edu/press/pr0612image.html. Neutron Star Swaps Lead to Short Gamma-Ray Bursts Cambridge, MA - Gamma-ray bursts are the most powerful explosions in the universe, emitting huge amounts of high-energy radiation. For decades their origin was a mystery. Scientists now believe they understand the processes that produce gamma-ray bursts. However, a new study by Jonathan Grindlay of the Harvard-Smithsonian Center for Astrophysics (CfA) and his colleagues, Simon Portegies Zwart (Astronomical Institute, The Netherlands) and Stephen McMillan (Drexel University), suggests a previously overlooked source for some gamma-ray bursts: stellar encounters within globular clusters. "As many as one-third of all short gamma-ray bursts that we observe may come from merging neutron stars in globular clusters," said Grindlay. http://www.cfa.harvard.edu/press/pr0612.html From owner-public@setileague.org Thu Feb 2 14:56:10 2006 X-Spam-Checker-Version: SpamAssassin 3.1.0 (2005-09-13) on Sentry.net X-Spam-Level: * X-Spam-Status: No, score=1.3 required=5.0 tests=MSGID_FROM_MTA_HEADER, RCVD_IN_BL_SPAMCOP_NET autolearn=no version=3.1.0 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id k12MuAff010458 for ; Thu, 2 Feb 2006 14:56:10 -0800 Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id RAA17040 for public-list; Thu, 2 Feb 2006 17:42:21 -0500 (EST) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from hotmail.com (bay114-f5.bay114.hotmail.com [65.54.169.15]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id RAA17036; Thu, 2 Feb 2006 17:42:18 -0500 (EST) Received: from mail pickup service by hotmail.com with Microsoft SMTPSVC; Thu, 2 Feb 2006 14:41:46 -0800 Message-ID: Received: from 65.54.169.200 by by114fd.bay114.hotmail.msn.com with HTTP; Thu, 02 Feb 2006 22:41:45 GMT X-Originating-IP: [24.39.94.195] X-Originating-Email: [ljk4@msn.com] X-Sender: ljk4@msn.com From: "LARRY KLAES" To: public@setileague.org Cc: bioastro@setileague.org Subject: SETI public: From Protoplanets to Protolife: The Emergence and Maintenance of Life Date: Thu, 02 Feb 2006 17:41:45 -0500 Mime-Version: 1.0 Content-Type: text/plain; format=flowed X-OriginalArrivalTime: 02 Feb 2006 22:41:46.0804 (UTC) FILETIME=[D92E1F40:01C62849] Sender: owner-public@setileague.org Precedence: bulk Astrophysics, abstract astro-ph/0602008 From: Eric J.

The origin of life as a planetary phenomenon will probably resist successful explanation as long as we lack an early record of its evolution and additional examples. It is widely thought that the geologic record shows that life emerged quickly after the end of prolonged bombardment of the Earth. New data and simulations contradict that view and suggest that more than half a billion years of unrecorded Earth history may have elapsed between the origin of life and LUCA. The impact-driven exchange of material between the inner planets may have allowed earliest life to be more cosmopolitan. Indeed, terrestrial life may not have originated on the Earth, or even on any planet. Smaller bodies, e.g. the parent bodies of primitive meteorites, offer alternative environments for the origin of life in our Solar System. The search for past or present life on Mars is an obvious path to greater enlightenment. The subsurface oceans of some icy satellites of the outer planets represent the best locales to search for an independent origin of life in the Solar System because of the high dynamical barriers for transfer, intense radiation at their surfaces, and thick ice crusts. The ``ultimate'' answer to the abundance of life in the Cosmos will remain the domain of speculation until we develop observatories capable of detecting habitable planets - and signs of life - around the nearest million or so stars. http://arxiv.org/abs/astro-ph/0602008 From owner-public@setileague.org Fri Feb 3 07:38:02 2006 X-Spam-Checker-Version: SpamAssassin 3.1.0 (2005-09-13) on Sentry.net X-Spam-Level: ** X-Spam-Status: No, score=2.1 required=5.0 tests=MSGID_FROM_MTA_HEADER, RCVD_IN_NJABL_PROXY,RCVD_IN_SORBS_SOCKS autolearn=no version=3.1.0 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id k13Fc13w018905 for ; Fri, 3 Feb 2006 07:38:01 -0800 Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id KAA10024 for public-list; Fri, 3 Feb 2006 10:27:13 -0500 (EST) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from hotmail.com (bay114-f15.bay114.hotmail.com [65.54.169.25]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id KAA10020; Fri, 3 Feb 2006 10:27:10 -0500 (EST) Received: from mail pickup service by hotmail.com with Microsoft SMTPSVC; Fri, 3 Feb 2006 07:26:39 -0800 Message-ID: Received: from 65.54.169.200 by by114fd.bay114.hotmail.msn.com with HTTP; Fri, 03 Feb 2006 15:26:38 GMT X-Originating-IP: [70.16.62.75] X-Originating-Email: [ljk4@msn.com] X-Sender: ljk4@msn.com From: "LARRY KLAES" To: public@setileague.org Cc: bioastro@setileague.org Subject: SETI public: Microlensing Sensitivity to Earth-mass Planets in the Habitable Zone Date: Fri, 03 Feb 2006 10:26:38 -0500 Mime-Version: 1.0 Content-Type: text/plain; format=flowed X-OriginalArrivalTime: 03 Feb 2006 15:26:39.0339 (UTC) FILETIME=[3A54DBB0:01C628D6] Sender: owner-public@setileague.org Precedence: bulk Astrophysics, abstract astro-ph/0602006 From: Cheongho Han [view email] Date: Tue, 31 Jan 2006 22:38:50 GMT (42kb) Microlensing Sensitivity to Earth-mass Planets in the Habitable Zone Authors: Byeong-Gon Park, Young-Beom Jeon, Chung-Uk Lee (KASI), Cheongho Han (Chungbuk Natl. Univ. Korea) Comments: ApJ, submitted Microlensing is one of the most powerful methods that can detect extrasolar planets and a future space-based survey with a high monitoring frequency is proposed to detect a large sample of Earth-mass planets. In this paper, we examine the sensitivity of the future microlensing survey to Earth-mass planets located in the habitable zone. For this, we estimate the fraction of Earth-mass planets that will be located in the habitable zone of their parent stars by carrying out detailed simulation of microlensing events based on standard models of the physical and dynamic distributions and the mass function of Galactic matter. From this investigation, we find that among the total detectable Earth-mass planets from the survey, those located in the habitable zone would comprise less than 1% even under a less-conservative definition of the habitable zone. We find the main reason for the low sensitivity is that the projected star-planet separation at which the microlensing planet detection efficiency becomes maximum (lensing zone) is in most cases substantially larger than the median value of the habitable zone. We find that the ratio of the median radius of the habitable zone to the mean radius of the lensing zone is roughly expressed as $d_{\rm HZ}/r_{\rm E}\sim 0.2(m/0.5 M_\odot)^{1/2}$. http://arxiv.org/abs/astro-ph/0602006 From owner-public@setileague.org Fri Feb 3 07:38:18 2006 X-Spam-Checker-Version: SpamAssassin 3.1.0 (2005-09-13) on Sentry.net X-Spam-Level: ** X-Spam-Status: No, score=2.1 required=5.0 tests=MSGID_FROM_MTA_HEADER, RCVD_IN_NJABL_PROXY,RCVD_IN_SORBS_SOCKS autolearn=no version=3.1.0 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id k13FcIMY018926 for ; Fri, 3 Feb 2006 07:38:18 -0800 Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id KAA09943 for public-list; Fri, 3 Feb 2006 10:24:43 -0500 (EST) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from hotmail.com (bay114-f4.bay114.hotmail.com [65.54.169.14]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id KAA09939; Fri, 3 Feb 2006 10:24:41 -0500 (EST) Received: from mail pickup service by hotmail.com with Microsoft SMTPSVC; Fri, 3 Feb 2006 07:24:10 -0800 Message-ID: Received: from 65.54.169.200 by by114fd.bay114.hotmail.msn.com with HTTP; Fri, 03 Feb 2006 15:24:09 GMT X-Originating-IP: [70.16.62.75] X-Originating-Email: [ljk4@msn.com] X-Sender: ljk4@msn.com From: "LARRY KLAES" To: public@setileague.org Cc: bioastro@setileague.org Subject: SETI public: From the Big Bang Theory to the Theory of a Stationary Universe Date: Fri, 03 Feb 2006 10:24:09 -0500 Mime-Version: 1.0 Content-Type: text/plain; format=flowed X-OriginalArrivalTime: 03 Feb 2006 15:24:10.0145 (UTC) FILETIME=[E167A910:01C628D5] Sender: owner-public@setileague.org Precedence: bulk General Relativity and Quantum Cosmology, abstract gr-qc/9306035 From: Andrei Linde [view email] Date: Tue, 29 Jun 1993 05:15:07 GMT (609kb) Date (revised): Wed, 1 Feb 2006 20:20:32 GMT Date (revised): Wed, 1 Feb 2006 21:03:31 GMT >From the Big Bang Theory to the Theory of a Stationary Universe Authors: Andrei Linde, Dmitri Linde, Arthur Mezhlumian Comments: No changes to the file, but original figures are included.

High quality figures can be found at this http URL Journal-ref: Phys.Rev. D49 (1994) 1783-1826 We consider chaotic inflation in the theories with the effective potentials phi^n and e^{\alpha\phi}. In such theories inflationary domains containing sufficiently large and homogeneous scalar field \phi permanently produce new inflationary domains of a similar type. We show that under certain conditions this process of the self-reproduction of the Universe can be described by a stationary distribution of probability, which means that the fraction of the physical volume of the Universe in a state with given properties (with given values of fields, with a given density of matter, etc.) does not depend on time, both at the stage of inflation and after it. This represents a strong deviation of inflationary cosmology from the standard Big Bang paradigm. We compare our approach with other approaches to quantum cosmology, and illustrate some of the general conclusions mentioned above with the results of a computer simulation of stochastic processes in the inflationary Universe. http://arxiv.org/abs/gr-qc/9306035 From owner-public@setileague.org Fri Feb 3 09:21:08 2006 X-Spam-Checker-Version: SpamAssassin 3.1.0 (2005-09-13) on Sentry.net X-Spam-Level: ** X-Spam-Status: No, score=2.1 required=5.0 tests=MSGID_FROM_MTA_HEADER, RCVD_IN_NJABL_PROXY,RCVD_IN_SORBS_SOCKS autolearn=no version=3.1.0 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id k13HL8FD021441 for ; Fri, 3 Feb 2006 09:21:08 -0800 Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id MAA12388 for public-list; Fri, 3 Feb 2006 12:10:06 -0500 (EST) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from hotmail.com (bay114-f2.bay114.hotmail.com [65.54.169.12]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id MAA12384; Fri, 3 Feb 2006 12:10:04 -0500 (EST) Received: from mail pickup service by hotmail.com with Microsoft SMTPSVC; Fri, 3 Feb 2006 09:09:28 -0800 Message-ID: Received: from 65.54.169.200 by by114fd.bay114.hotmail.msn.com with HTTP; Fri, 03 Feb 2006 17:09:27 GMT X-Originating-IP: [70.16.62.75] X-Originating-Email: [ljk4@msn.com] X-Sender: ljk4@msn.com From: "LARRY KLAES" To: public@setileague.org Cc: bioastro@setileague.org Subject: SETI public: 3 papers on planetesimals and circumstellar disks Date: Fri, 03 Feb 2006 12:09:27 -0500 Mime-Version: 1.0 Content-Type: text/plain; format=flowed X-OriginalArrivalTime: 03 Feb 2006 17:09:28.0800 (UTC) FILETIME=[979DE600:01C628E4] Sender: owner-public@setileague.org Precedence: bulk Paper: astro-ph/0602041 Date: Thu, 2 Feb 2006 13:42:06 GMT (461kb) Title: Dust in Proto-Planetary Disks: Properties and Evolution Authors: A. Natta (Arcetri), L. Testi (Arcetri), N. Calvet (Michigan), Th. Henning (MPIA), R. Waters (Amsterdam), D. Wilner (CfA) Comments: Protostars and Planets V in press, 16 pages, 7 figures \\ We review the properties of dust in protoplanetary disks around optically visible pre-main sequence stars obtained with a variety of observational techniques, from measurements of scattered light at visual and infrared wavelengths to mid-infrared spectroscopy and millimeter interferometry. A general result is that grains in disks are on average much larger than in the diffuse interstellar medium (ISM). In many disks, there is evidence that a large mass of dust is in grains with millimeter and centimeter sizes, more similar to "sand and pebbles" than to grains. Smaller grains (with micron-sizes) exist closer to the disk surface, which also contains much smaller particles, e.g., polycyclic aromatic hydrocarbons. There is some evidence of a vertical stratification, with smaller grains closer to the surface. Another difference with ISM is the higher fraction of crystalline relative to amorphous silicates found in disk surfaces. There is a large scatter in dust properties among different sources, but no evidence of correlation with the stellar properties, for samples that include objects from intermediate to solar mass stars and brown dwarfs. There is also no apparent correlation with the age of the central object, over a range roughly between 1 and 10 Myr. This suggests a scenario where significant grain processing may occur very early in the disk evolution, possibly when it is accreting matter from the parental molecular core. Further evolution may occur, but not necessarily rapidly, since we have evidence that large amounts of grains, from micron to centimeter size, can survive for periods as long as 10 Myr. \\ ( http://arXiv.org/abs/astro-ph/0602041 , 461kb) Paper: astro-ph/0602046 Date: Thu, 2 Feb 2006 15:08:15 GMT (252kb) Title: Relative velocities among accreting planetesimals in binary systems: the circumprimary case Authors: P. Thebault, F. Marzari, H. Scholl Comments: to appear in Icarus (accepted 30 january 2006) \\ We investigate classical planetesimal accretion in a binary star system of separation ab<50AU by numerical simulations, with particular focus on the region at a distance of 1 AU from the primary. The planetesimals orbit the primary, are perturbed by the companion and are in addition subjected to a gas drag force. We concentrate on the problem of relative velocities dv among planetesimals of different sizes. For various stellar mass ratios and binary orbital parameters we determine regions where dv exceed planetesimal escape velocities v_esc (thus preventing runaway accretion) or even the threshold velocity v_ero for which erosion dominates accretion. Gaseous friction has two crucial effects on the velocity distribution: it damps secular perturbations by forcing periastron alignment of orbits, but at the same time the size--dependence of this orbital alignment induces a significant dv increase between bodies of different sizes. This differential phasing effect proves very efficient and almost always increases dv to values preventing runaway accretion, except in a narrow domain of almost circular companion orbits. The erosion threshold dv>v_ero is reached in a wide (ab,eb) space for small (<10km) planetesimals, but in a much more limited region for bigger ~50km objects. In the intermediate v_esc 5 % of the total carbon abundance is locked up in nanoparticles. We test the sensitivity of this prediction to various stellar and disk parameters and show that if the potential contamination of the spinning dust component by the free-free and/or synchrotron emission can be removed, then the best chances of detecting this emission would be in disks with small opacity, having SEDs with steep sub-mm slopes (which minimizes thermal disk emission at GHz frequencies). Detection of the spinning dust emission would provide important evidence for the existence, properties, and origin of the population of small dust particles in protoplanetary disks, with possible ramifications for planet formation. \\ ( http://arXiv.org/abs/astro-ph/0602030 , 58kb) From owner-public@setileague.org Mon Feb 6 07:18:00 2006 X-Spam-Checker-Version: SpamAssassin 3.1.0 (2005-09-13) on Sentry.net X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=ham version=3.1.0 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id k16FHxsu016706 for ; Mon, 6 Feb 2006 07:17:59 -0800 Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id KAA25718 for public-list; Mon, 6 Feb 2006 10:10:14 -0500 (EST) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from rodin.limsi.fr (rodin.limsi.fr [129.175.152.156]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id KAA25714 for ; Mon, 6 Feb 2006 10:10:11 -0500 (EST) Received: from [129.175.152.152] (albireo.limsi.fr [129.175.152.152]) by rodin.limsi.fr (8.13.4/8.13.4/Debian-3) with ESMTP id k16FA45n014354 for ; Mon, 6 Feb 2006 16:10:06 +0100 Message-ID: <43E766CC.5010009@libertysurf.fr> Date: Mon, 06 Feb 2006 16:10:04 +0100 From: Elisabeth Piotelat User-Agent: Debian Thunderbird 1.0.2 (X11/20051002) X-Accept-Language: en-us, en MIME-Version: 1.0 To: public@setileague.org Subject: SETI public: Active SETI / Cosmic Connexion Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit X-LIMSI-rodin-MailScanner: Found to be clean X-LIMSI-rodin-MailScanner-SpamCheck: not spam (whitelisted), SpamAssassin (score=-2.099, requis 5, BAYES_00 -2.60, LIMSI_55 0.50) X-MailScanner-Auteur: league.seti@libertysurf.fr X-MailScanner-Dest: public@setileague.org Sender: owner-public@setileague.org Precedence: bulk Hi, A french-german TV is calling for messages... to be sent this autumn. http://www.cosmicconnexion.com/static/home-en.html I don't know if thay have asked IAA before broadcasting :-( All I know is that they met Claudio Maccone and may be Franck Drake.

COROT is set for launch in June of 2006. http://smsc.cnes.fr/COROT/ http://www.esa.int/science/corot http://cfa-www.harvard.edu/planets/corot.html Not that we should refine our ETI searches just to planets (some would argue we will have better chances aiming our telescopes at regions which show up in the infrared but not the optical), but 47 UM does have at least two Jupiter-class worlds orbiting at fairly large distances from their star (unlike all those other exogiants that practically skim the photospheres), allowing at least the possibility of an Earth-size world in the habitable zones. See here: http://www.solstation.com/stars2/47uma.htm Will the messages being sent out by CNES "survive" the 46 light year journey to 47 UM? Will they even be comprehensible to anyone there? Will it at least let any ETI present know they are not alone and motivate them to respond? Is it wiser to keep our mouths shut and let someone else contact us first? Or do we gain nothing by hiding under our beds - except dust?

Neuhaeuser, T. Mazeh, E. Guenther, M. Fernandez, C. Broeg Comments: accepted for publication in AN, 7 pages, 4 figures We have carried out a search for co-moving stellar and substellar companions around 18 exoplanet host stars with the infrared camera MAGIC at the 2.2m Calar Alto telescope, by comparing our images with images from the all sky surveys 2MASS, POSS I and II. Four stars of the sample namely HD80606, 55Cnc, HD46375 and BD-103166, are listed as binaries in the Washington Visual Double Star Catalogue (WDS). The binary nature of HD80606, 55Cnc, and HD46375 is confirmed with both astrometry as well as photometry, thereby the proper motion of the companion of HD46375 was determined here for the first time. We derived the companion masses as well as the longterm stability regions for additional companions in these three binary systems. We can rule out further stellar companions around all stars in the sample with projected separations between 270AU and 2500AU, being sensitive to substellar companions with masses down to \~60MJup (S/N=3). Furthermore we present evidence that the two components of the WDS binary BD-103166 are unrelated stars, i.e this system is a visual pair. The spectrophotometric distance of the primary (a K0 dwarf) is ~67pc, whereas the presumable secondary BD-103166B (a M4 to M5 dwarf) is located at a distance of 13pc in the foreground. http://arxiv.org/abs/astro-ph/0602067 From owner-public@setileague.org Tue Feb 7 00:52:42 2006 X-Spam-Checker-Version: SpamAssassin 3.1.0 (2005-09-13) on Sentry.net X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=ham version=3.1.0 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id k178qgPx016627 for ; Tue, 7 Feb 2006 00:52:42 -0800 Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id DAA24033 for public-list; Tue, 7 Feb 2006 03:43:25 -0500 (EST) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from rodin.limsi.fr (rodin.limsi.fr [129.175.152.156]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id DAA24024; Tue, 7 Feb 2006 03:43:20 -0500 (EST) Received: from [129.175.152.152] (albireo.limsi.fr [129.175.152.152]) by rodin.limsi.fr (8.13.4/8.13.4/Debian-3) with ESMTP id k178gdqU027711; Tue, 7 Feb 2006 09:42:40 +0100 Message-ID: <43E85D7F.6040500@libertysurf.fr> Date: Tue, 07 Feb 2006 09:42:39 +0100 From: Elisabeth Piotelat User-Agent: Debian Thunderbird 1.0.2 (X11/20051002) X-Accept-Language: en-us, en MIME-Version: 1.0 To: LARRY KLAES CC: public@setileague.org, bioastro@setileague.org Subject: Re: SETI public: Active SETI / Cosmic Connexion References: In-Reply-To: Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit X-LIMSI-rodin-MailScanner: Found to be clean X-LIMSI-rodin-MailScanner-SpamCheck: not spam (whitelisted), SpamAssassin (score=-6.099, requis 5, autolearn=not spam, BAYES_00 -2.60, HTTP_FR -4.00, LIMSI_55 0.50) X-MailScanner-Auteur: league.seti@libertysurf.fr X-MailScanner-Dest: bioastro@setileague.org, ljk4@msn.com, public@setileague.org Sender: owner-public@setileague.org Precedence: bulk Hi Larry, I'm not sure both things are linked so closely. The idea of "sending a TV broadcast to stars" comes from the producer. They contact me asking "how can we do this ?". I forwarded their request to several astronomers. When they told me they had contact with people at CNES, I just suggest them to ask if they had any idea of how to transmit the broadcast. You ask some good questions :-) I will see if I can get some technical details from CNES.

One of its main missions will be to look for extrasolar planets, including so-called 'telluric' planets, which are similar to the Earth. As part of this hopeful project, a special programme will be broadcast on ARTE and into space via a CNES space centre antenna." I have read that the COROT launch is actually scheduled for this June, but please correct me if I am wrong here. I would also like to know how strong the signal will be? If they don't make it a strong signal, then the whole thing is little more than an artistic stunt and telling people that their messages will reach aliens in another star system is nothing more than a deception. I also have strong doubts that anything will be done to make any of the messages understandable, but again, please prove me wrong. And why are they aiming it at just one star system?

If there was one singular mission that embodied humanity casting its collective "vision" outward "into the cosmos" so as to look for places to "head" toward, it was the Terrestrial Planet Finder. This is a bad decision. A really bad one. In making it, one has to question whether this White House really meant what it said 2 years ago when it raised everyone's expectations, invoking an expansion "into the cosmos" in so doing.

Beacom (Ohio State University) Comments: Accepted for publication in New Astronomy Reviews (invited talk at "Astronomy with Radioactivities V", Clemson Univ., Sept. 2005). 9 pages, 5 figures The cosmic stellar birth rate can be measured by standard astronomical techniques. It can also be probed via the cosmic stellar death rate, though until recently, this was much less precise. However, recent results based on measured supernova rates, and importantly, also on the attendant diffuse fluxes of neutrinos and gamma rays, have become competitive, and a concordant history of stellar birth and death is emerging. The neutrino flux from all past core-collapse supernovae, while faint, is realistically within reach of detection in Super-Kamiokande, and a useful limit has already been set. I will discuss predictions for this flux, the prospects for neutrino detection, the implications for understanding core-collapse supernovae, and a new limit on the contribution of type-Ia supernovae to the diffuse gamma-ray background. http://arxiv.org/abs/astro-ph/0602101 Astrophysics, abstract astro-ph/0602122 From: Adam J.

Burgasser (MIT), I. Neill Reid (STScI), Nick Siegler (UA Steward), Laird Close (UA Steward), Peter Allen (Penn State), Patrick Lowrance (SSC), John Gizis (U Delaware) Comments: 16 pages, 7 figures, contributed chapter for Planets and Protostars V meeting (October 2005); full table of VLM binaries can be obtained at this http URL The properties of multiple stellar systems have long provided important empirical constraints for star formation theories, enabling (along with several other lines of evidence) a concrete, qualitative picture of the birth and early evolution of normal stars. At very low masses (VLM; M <~ 0.1 M_sun), down to and below the hydrogen burning minimum mass, our understanding of formation processes is not as clear, with several competing theories now under consideration. One means of testing these theories is through the empirical characterization of VLM multiple systems. Here, we review the results of various VLM multiplicity studies to date. These systems can be generally characterized as closely separated (93% have projected separations Delta < 20 AU) and near equal-mass (77% have M_2/M_1 >= 0.8) occurring infrequently (perhaps 10-30%). Both the frequency and maximum separation of stellar and brown dwarf binaries steadily decrease for lower system masses, suggesting that VLM binary formation and/or evolution may be a mass-dependent process. There is evidence for a fairly rapid decline in the number of loosely-bound systems below ~0.3 M_sun, corresponding to a factor of 10-20 increase in the minimum binding energy of VLM binaries as compared to more massive stellar binaries. This wide-separation ``desert'' is present among both field (~1-5 Gyr) and older (> 100 Myr) cluster systems, while the youngest (<~10 Myr) VLM binaries, particularly those in nearby, low-density star forming regions, appear to have somewhat different systemic properties. We compare these empirical trends to predictions laid out by current formation theories, and outline future observational studies needed to probe the full parameter space of the lowest mass multiple systems. http://arxiv.org/abs/astro-ph/0602122 Astrophysics, abstract astro-ph/0602096 From: Markus Landgraf [view email] Date: Sun, 5 Feb 2006 03:47:54 GMT (471kb) The Sky in Dust -- Methods and Prospects of Dust Astronomy Authors: M.

Dust particles, like photons, carry information from remote sites in space and time. This information can be analysed in order to understand the processes and mechanisms that are involved in the formation and evolution of solid matter in the galaxy. This approach is called ``Dust Astronomy'' which is carried out by means of a dust telescope on a dust observatory in space. The analysis of cosmic grains collected in the high atmosphere of the Earth has shown that each dust grain is a small world with various sub-grains featuring different galactic origin and evolution, which is identified on the basis of elementary and isotopic analysis. Independent information about the origin and evolution of the grains coming from the kinematic properties of the arrival trajectory would be invaluable for linking the isotopic signature of the formation of heavy elements in old stars and supernovae to distinctive regions in our galaxy, e.g. known star-forming regions. Here we present a skymap of potential dust sources together with a report on already existing lab hardware of a trajectory sensor and a large-area mass spectrometre. http://arxiv.org/abs/astro-ph/0602096 Astrophysics, abstract astro-ph/0602117 From: T.

Bakos (1,2), Andras Pal (3,1), David W. Latham (1), Robert W. Noyes (1), Robert P. Stefanik (1) ((1) CfA, (2) Hubble Fellow, (3) E"otv"os Lorand University, Department of Astronomy) Comments: 4 pages, submitted to APJ Letters We show that the very close-by (19 pc) K0 star HD 189733, already found to be orbited by a transiting giant planet, is the primary of a double-star system, with the secondary being a mid-M dwarf with projected separation of about 216 AU from the primary. This conclusion is based on astrometry, proper motion and radial velocity measurements, spectral type determination and photometry. We also detect differential proper motion of the secondary. The data appear consistent with the secondary orbiting the primary in a clockwise orbit, lying nearly in the plane of the sky (that is, nearly perpendicular to the orbital plane of the transiting planet), and with period about 3200 years. http://arxiv.org/abs/astro-ph/0602136 Astrophysics, abstract astro-ph/0602154 From: C.

Walch Comments: Accepted for publication in ApJL We present a new perspective on the crystallinity of dust in protoplanetary disks. The dominant crystallization by thermal annealing happens in the very early phases of disk formation and evolution. Both the disk properties and the level of crystallinity are thereby directly linked to the properties of the molecular cloud core from which the star+disk system was formed. We show that, under the assumption of single star formation, rapidly rotating clouds produce disks which, after the main infall phase (i.e. in the optically revealed class II phase), are rather massive and have a high accretion rate but low crystallinity. Slowly rotating clouds, on the other hand, produce less massive disks with lower accretion rate, but high levels of crystallinity. Cloud fragmentation and the formation of multiple stars complicates the problem and necessitates further study. The underlying physics of the model is insufficiently understood to provide the precise relationship between crystallinity, disk mass and accretion rate. But the fact that with `standard' input physics the model produces disks which, in comparison to observations, appear to have either too high levels of crystallinity or too high disk masses, demonstrates that the comparison of these models to observations can place strong contraints on the disk physics. The question to ask is not why some sources are so crystalline, but why some other sources have such a low level of crystallinity. http://arxiv.org/abs/astro-ph/0602154 From owner-public@setileague.org Wed Feb 8 16:25:58 2006 X-Spam-Checker-Version: SpamAssassin 3.1.0 (2005-09-13) on Sentry.net X-Spam-Level: X-Spam-Status: No, score=-2.6 required=5.0 tests=BAYES_00, MSGID_FROM_MTA_HEADER autolearn=unavailable version=3.1.0 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id k190Pwvf031422 for ; Wed, 8 Feb 2006 16:25:58 -0800 Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id TAA27146 for public-list; Wed, 8 Feb 2006 19:20:16 -0500 (EST) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from hotmail.com (bay114-f18.bay114.hotmail.com [65.54.169.28]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id TAA27141; Wed, 8 Feb 2006 19:20:13 -0500 (EST) Received: from mail pickup service by hotmail.com with Microsoft SMTPSVC; Wed, 8 Feb 2006 16:19:38 -0800 Message-ID: Received: from 65.54.169.200 by by114fd.bay114.hotmail.msn.com with HTTP; Thu, 09 Feb 2006 00:19:37 GMT X-Originating-IP: [70.16.55.37] X-Originating-Email: [ljk4@msn.com] X-Sender: ljk4@msn.com From: "LARRY KLAES" To: public@setileague.org Cc: bioastro@setileague.org Subject: SETI public: Pioneer Anomaly on TPS Planetary Radio Date: Wed, 08 Feb 2006 19:19:37 -0500 Mime-Version: 1.0 Content-Type: text/plain; format=flowed X-OriginalArrivalTime: 09 Feb 2006 00:19:38.0636 (UTC) FILETIME=[838B14C0:01C62D0E] Sender: owner-public@setileague.org Precedence: bulk Planetary Radio had an interview with JPL's John Anderson on February 6, 2006: Closing In On An Interplanetary Mystery: The Pioneer Anomaly Airdate: Monday, February 6, 2006 Running Time: 00:28:50 Listen: Windows Media | MP3 JPL Senior Research Scientist John Anderson updates the Pioneer Anomaly casebook, and reports that there may be one more attempt to contact the thirty-four year old Pioneer 10 next month.

Authors: Denis Defrere, Andreas Rathke Comments: 19 pages, 4 figures. Talk given by D. Defrere at the conference "Lasers, Clocks, and Drag-Free", ZARM, Bremen, Germany, 30 May - 1 June 2005 The Doppler tracking data from two deep-space spacecraft, Pioneer 10 and 11, show an anomalous blueshift, which has been dubbed the "Pioneer anomaly". The effect is most commonly interpreted as a real deceleration of the spacecraft - an interpretation that faces serious challenges from planetary ephemerides. The Pioneer anomaly could as well indicate an unknown effect on the radio signal itself. Several authors have made suggestions how such a blueshift could be related to cosmology. We consider this interpretation of the Pioneer anomaly and study the impact of an anomalous blueshift on the Laser Interferometer Space Antenna (LISA), a planned joint ESA-NASA mission aiming at the detection of gravitational waves. The relative frequency shift (proportional to the light travel time) for the LISA arm length is estimated to 10E-16, which is much bigger than the expected amplitude of gravitational waves. The anomalous blueshift enters the LISA signal in two ways, as a small term folded with the gravitational wave signal, and as larger term at low frequencies. A detail analysis shows that both contributions remain undetectable and do not impair the gravitational-wave detection. This suggests that the Pioneer anomaly will have to be tested in the outer Solar system regardless if the effect is caused by an anomalous blueshift or by a real force. http://arxiv.org/abs/gr-qc/0509021 General Relativity and Quantum Cosmology, abstract gr-qc/0602003 From: Antonio F. Ranada [view email] Date: Wed, 1 Feb 2006 15:30:16 GMT (10kb) A model for the Pioneer Anomaly Authors: Antonio F. Ranada, Alfredo Tiemblo Comments: 11 pages, no figures We propose an explanation to the Pioneer Anomaly, the anomalous blueshift in the radio signals from the Pioneer 10/11 spacecrafts that remains unexplained 30 years after being discovered by a NASA team around 1975. It was detected as a Doppler shift that does not correspond to any known motion of the ships. In 1998, after many unsuccessful efforts to account for it, the discoverers suggested "the possibility that the origin of the anomalous signal is new physics". We show here that the phenomenon has the same observational footprint as an acceleration of the atomic clocks time with respect to the astronomical time. Surprisingly, this curious new idea turns out to be compatible with current physics; lacking a unified theory of quantum physics and gravitation, we cannot discard it a priori. We expound a mechanism that produces such an acceleration as a result of the coupling of the background gravitation and the quantum vacuum. This suggests a solution to the riddle, in which the velocity of a receding ship, as deduced from the Doppler effect, is smaller than the value predicted by the standard theory of gravitation. We conclude that the Pioneer Anomaly is probably the signature of the difference between the marches of the astronomical clock of the orbit and the atomic clock inside the ship. http://arxiv.org/abs/gr-qc/0602003 From owner-public@setileague.org Thu Feb 9 11:03:30 2006 X-Spam-Checker-Version: SpamAssassin 3.1.0 (2005-09-13) on Sentry.net X-Spam-Level: X-Spam-Status: No, score=-2.6 required=5.0 tests=BAYES_00, MSGID_FROM_MTA_HEADER autolearn=unavailable version=3.1.0 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id k19J3UMG006522 for ; Thu, 9 Feb 2006 11:03:30 -0800 Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id NAA26142 for public-list; Thu, 9 Feb 2006 13:54:26 -0500 (EST) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from hotmail.com (bay114-f13.bay114.hotmail.com [65.54.169.23]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id NAA26125; Thu, 9 Feb 2006 13:54:23 -0500 (EST) Received: from mail pickup service by hotmail.com with Microsoft SMTPSVC; Thu, 9 Feb 2006 10:53:51 -0800 Message-ID: Received: from 65.54.169.200 by by114fd.bay114.hotmail.msn.com with HTTP; Thu, 09 Feb 2006 18:53:51 GMT X-Originating-IP: [70.16.50.54] X-Originating-Email: [ljk4@msn.com] X-Sender: ljk4@msn.com From: "LARRY KLAES" To: public@setileague.org Cc: bioastro@setileague.org Subject: SETI public: Do extragalactic cosmic rays induce cycles in fossil diversity?

Medvedev [view email] Date: Sat, 4 Feb 2006 08:41:11 GMT (144kb) Do extragalactic cosmic rays induce cycles in fossil diversity? Authors: Mikhail V. Medvedev, Adrian L. Melott (University of Kansas) Comments: 13 pages, 3 figures, submitted to Nature Subj-class: Astrophysics; Geophysics; Plasma Physics; Atmospheric and Oceanic Physics; Populations and Evolution The idea of cycles in fossil diversity has recently been put on a firm statistical footing, revealing a 62{plus-minnus}3-million-year cycle in the number of marine genera. The strong signal requires a periodic process extending back at least 540 My, which is difficult to explain by any terrestrial process. While astro- and geophysical phenomena may be periodic for such a long time, no plausible mechanism has been found. The fact that the period of the diversity cycle is close to the 64 My period of the vertical oscillation of the Solar system relative to the galactic disk is suggestive. However, any model involving cosmogenic processes modulated by the Sun's midplane crossing or its maximal vertical distance from the galactic plane predicts a half-period cycle, i.e. about 32 My. Here we propose that the diversity cycle is caused by the anisotropy of cosmic ray (CR) production in the galactic halo/wind/termination shock and the shielding effect of the galactic magnetic fields. CRs influence cloud formation, can affect climate and harm live organisms directly via increase of radiation dose. The CR anisotropy is caused by the galactic north-south asymmetry of the termination shock due to the interaction with the ``warm-hot intergalactic medium'' as our galaxy falls toward the Virgo cluster (nearly in the direction of the galactic north pole) with a velocity of order 200 km/s. Here we revisit the mechanism of CR propagation in the galactic magnetic fields and show that the shielding effect is strongly position-dependent. It varies by a factor of a hundred and reaches a minimum at the maximum northward displacement of the Sun. Very good phase agreement between maximum excursions of the Sun toward galactic north and minima of the fossil diversity cycle further supports our model. http://arxiv.org/abs/astro-ph/0602092 From owner-public@setileague.org Fri Feb 10 06:21:01 2006 X-Spam-Checker-Version: SpamAssassin 3.1.0 (2005-09-13) on Sentry.net X-Spam-Level: X-Spam-Status: No, score=-2.6 required=5.0 tests=BAYES_00, MSGID_FROM_MTA_HEADER autolearn=ham version=3.1.0 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id k1AEKwJG022642 for ; Fri, 10 Feb 2006 06:21:00 -0800 Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id JAA27004 for public-list; Fri, 10 Feb 2006 09:14:03 -0500 (EST) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from hotmail.com (bay114-f13.bay114.hotmail.com [65.54.169.23]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id JAA26999; Fri, 10 Feb 2006 09:14:01 -0500 (EST) Received: from mail pickup service by hotmail.com with Microsoft SMTPSVC; Fri, 10 Feb 2006 06:13:29 -0800 Message-ID: Received: from 65.54.169.200 by by114fd.bay114.hotmail.msn.com with HTTP; Fri, 10 Feb 2006 14:13:28 GMT X-Originating-IP: [71.240.240.30] X-Originating-Email: [ljk4@msn.com] X-Sender: ljk4@msn.com From: "LARRY KLAES" To: public@setileague.org Cc: bioastro@setileague.org Subject: SETI public: Biocosm, The New Scientific Theory of Evolution Date: Fri, 10 Feb 2006 09:13:28 -0500 Mime-Version: 1.0 Content-Type: text/plain; format=flowed X-OriginalArrivalTime: 10 Feb 2006 14:13:29.0559 (UTC) FILETIME=[2AB5D670:01C62E4C] Sender: owner-public@setileague.org Precedence: bulk ************************* Biocosm, The New Scientific Theory of Evolution James N.

Ponder that Pioneer 10 was launched in 1972 and consider that even with the technologies of its day, the probe may still be able to communicate with Earth. We have learned so much in the interim about hardened electronics and autonomous self-repair that there is reason to believe probes to even remoter locations in the Kuiper Belt and beyond are feasible providing we can solve the propulsion conundrum. ... It’s too late for New Horizons, of course, but any followup Pluto/Kuiper Belt mission would have such an opportunity. On that score, see T. Bondo, R. Walker, A. Rathke et al., “Preliminary Design of an Advanced Mission to Pluto,” scheduled to appear in the proceedings of the 24th International Symposium on Space Technology and Science, Miyazaki, Japan, June 2006, and already available online (PDF warning). http://www.centauri-dreams.org/?p=534 From owner-public@setileague.org Mon Feb 13 08:26:18 2006 X-Spam-Checker-Version: SpamAssassin 3.1.0 (2005-09-13) on Sentry.net X-Spam-Level: X-Spam-Status: No, score=-1.0 required=5.0 tests=BAYES_00, MSGID_FROM_MTA_HEADER,RCVD_IN_BL_SPAMCOP_NET autolearn=no version=3.1.0 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id k1DGQHxA003488 for ; Mon, 13 Feb 2006 08:26:17 -0800 Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id LAA24092 for public-list; Mon, 13 Feb 2006 11:22:31 -0500 (EST) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from hotmail.com (bay114-f17.bay114.hotmail.com [65.54.169.27]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id LAA24088; Mon, 13 Feb 2006 11:22:28 -0500 (EST) Received: from mail pickup service by hotmail.com with Microsoft SMTPSVC; Mon, 13 Feb 2006 08:21:56 -0800 Message-ID: Received: from 65.54.169.200 by by114fd.bay114.hotmail.msn.com with HTTP; Mon, 13 Feb 2006 16:21:55 GMT X-Originating-IP: [24.39.94.195] X-Originating-Email: [ljk4@msn.com] X-Sender: ljk4@msn.com From: "LARRY KLAES" To: public@setileague.org Cc: bioastro@setileague.org Subject: SETI public: Sixtieth anniversary of first radar signals bounced off Luna Date: Mon, 13 Feb 2006 11:21:55 -0500 Mime-Version: 1.0 Content-Type: text/plain; format=flowed X-OriginalArrivalTime: 13 Feb 2006 16:21:56.0449 (UTC) FILETIME=[9B9D2D10:01C630B9] Sender: owner-public@setileague.org Precedence: bulk The very first "probe" on the surface of Earth's moon Luna happened when researchers of the Engineering Laboratories, U.S. Army Signals Corps, established the first radio link with the Moon by bouncing radar signals off the lunar surface on January 10, 1946, sixty years ago.

We will still do the Space Interferometry Mission, the Terrestrial Planet Finder, and the Global Precipitation Monitoring mission. We will not do them right now. In making a decision concerning what to delay and what to keep on schedule to the extent possible, I determined that delays in starting SIM, TPF, and GPM would be less harmful to the space program overall than would further delays to the CEV program. I simply believe that further delays to CEV are strategically more damaging to this nation than are delays to other missions. I stand by this view."
