    Good morning.

    Coming up the launch of SMART-1 to the Moon by way of an Arian 5, passenger
    number 3, doors opening, next stop, the Moon.

    This will not be the fire cracker push of a Trans Lunar Injection (TLI)
    rocket burn for a few minutes but rather the soft whisper of continuous push
    from an ION engine.

    Rather than go immediately from a circular orbit to an elliptical one, to a
    circular one ( HOMANN TRANSFER - TLI -
    http://liftoff.msfc.nasa.gov/academy/rocket_sci/satellites/hohmann.html ) it
    will just continue to push in an ever larger circular spiral and eventually
    get to the Moon where it will have to be caught by the Moon's gravitational
    attraction and then slow down to circularize around the Moon.

    There will be adjustments as the Moon goes around EARTH as well, and is
    nearer and helps pull you out. Then there will be a point where the Moon is
    pulling too much and you will need to slow down. This will take some time
    and is different from the 105 hour trip that Lunar Prospector took after the
    TLI kick. - LRK -

    SMART-1 has been a proposal for some time and now finally going to go. Will
    see if it takes 17 months as was mentioned back in 2000.

    Orbit
    16-month transfer orbit from Earth to the Moon. The final operational
    science orbit is a polar elliptical orbit, ranging from 300 kilometres to 10

    Mission

    SMART-1 is the first of ESA's 'Small Missions for Advanced Research in
    Technology'. It will head for the Moon using revolutionary propulsion
    techniques and carry a battery of miniaturised instruments. As well as
    testing new technology, SMART-1 will make the first comprehensive inventory
    of key chemical elements in the lunar surface. It will also investigate the
    theory that the Moon was formed following the violent collision of a smaller
    planet with Earth, four and a half thousand million years ago.

    European Space Agency
    Paris, 8 August 2003
    Press Release
    N° 50-2003

    Europe's first Moon probe prepares for launch

    Europe's first probe to the Moon, SMART-1, is about to begin a unique
    journey that will take it into orbit around our closest neighbour powered
    only by an ion engine, which Europe will be testing for the first time as
    main spacecraft propulsion.

    The European Space Agency's SMART-1 spacecraft was delivered to Kourou,
    French Guiana, on July 15 and is currently being prepared for launch atop
    an Ariane 5 during the night from August 28 to 29. The launch window will
    open at 20:04 local time (01:04 on August 29 morning CEST) and will remain
    open for 26 minutes.

    The 367 kg spacecraft will share Ariane's V162 launch with two commercial
    payloads: the Indian Space Research Organisation's Insat 3E and Eutelsat's
    e-Bird communication satellites. The smallest spacecraft in the trio,
    SMART-1, will travel in the lower position, inside a cylindrical adapter,
    and will be the last to be released.

    A generic Ariane 5 will be in charge of placing these three payloads in a
    standard geostationary transfer orbit from which each will begin its own
    journey towards its final operational orbit. SMART-1, powered by its ion
    engine, will reach its destination in about 16 months, having followed a
    long spiralling trajectory.

    SMART-1's ion engine will be used to accelerate the probe and raise its
    orbit until it reaches the vicinity of the Moon, some 350,000 to 400,000
    km from Earth. Then, following gravity assists from a series of lunar
    swingbys in late September, late October and late November 2004, SMART-1
    will be "captured" by the Moon's gravity in December 2004 and will begin
    using its engine to slow down and reduce the altitude of its lunar orbit.

    Testing breakthrough technologies and studying the Moon

    SMART-1 is not a standard outer space probe. As ESA's first Small Mission
    for Advanced Research in Technology, it is primarily designed to
    demonstrate innovative and key technologies for future deep space science
    missions. However, once it has arrived at its destination, it will also
    perform an unprecedented scientific study of the Moon. SMART-1 is a very
    small spacecraft (measuring just one cubic metre). Its solar arrays,
    spanning 14 metres, will deliver 1.9 kW of power, about 75% of which will
    be used for the probe's 'solar electric' propulsion system.

    In its role as technological demonstrator, SMART-1's primary goal is to
    test this new solar electric propulsion system. This is a form of
    continuous low-thrust engine that uses electricity derived from solar
    panels to produce a beam of charged particles that pushes the spacecraft
    forward. Such engines are commonly called ion engines, and engineers
    consider them essential for future, long-range space missions. SMART-1
    will also test miniaturised spacecraft equipment and instruments, a
    navigation system that, in the future, will allow spacecraft to
    autonomously navigate through the solar system, and in addition to a new
    short-wavelength communication system, a space communication technique by
    means of which SMART-1 will try to establish a link with the Earth using a
    laser beam.

    Once it enters into a near-polar orbit around the Moon in January 2005,
    SMART-1 will also become a science platform for lunar observation. SMART-1
    will search for signs of water-ice in craters near the Moon's poles,
    provide data to shed light on the still uncertain origin of the Moon, and
    reconstruct its evolution by mapping its topography and the surface
    distribution of minerals and key chemical elements.

    SMART-1 will be the second ESA-led planetary mission to be launched in
    2003 after Mars Express in June.

    Welcome!

    25 June 2003
    Dear user,
    Welcome to the new ESA Science General Public and Media web site!

    This site has been made for you: the general public and the media. It is
    designed to give you all the information you need to know about our Space
    Science Programme, or just to satisfy your curiosity!

    There are many new features through which you can share the excitement of
    our European science adventure in space. There is a Media Centre with the
    latest news stories, press releases and factsheets, a multimedia archive
    hosting high-quality images, video clips and 'sounds'. Other new features
    will be introduced in the next few months.

    Our user-friendly language, together with a clear navigation system, a
    distinction between media information packages and general public features,
    will make this site useful, entertaining and instructive.

    If you want the more technical details of our Space Science Programme and
    missions, use the direct entry point to the Science and Technology web site
    (http://sci.esa.int) offered on these pages.

    We hope you will enjoy using our web site as much as we have enjoyed
    building it! If you visit us regularly, there will be some nice surprises...
