He imagined robots the size of soft-drink cans with software systems > mimicking biological processes, which would be able to adapt to and deal with > unanticipated problems and thus evolve into "intelligent interstellar probes." > > Mr. Goldin also spoke of deploying into deep space "gossamer telescopes" with > mirrors several hundred feet wide (Hubble's is less than eight feet) and arrays of > widely separated telescopes capable of coordinated observations for even sharper > images of the cosmos. Other space probes might be able to measure gravitational > radiation from the first microseconds of the universe's creation in the theorized Big > Bang. One might even be sent to hover over and obtain direct images of the > consuming gravitational forces at regions known as black holes. > > The audience of senior astronomers as well as graduate students just starting their > careers broke into laughter when Mr. Goldin, driving home his anticomplacency > message, said, "Too many of you are hugging the Hubble Space Telescope." > > It was the knowing laughter that comes from hearing a truth exposed. Because of > years of budget constraints, astronomers said later, those in the field had stopped > dreaming and were clinging to what they had, dwelling on ways to keep the > Hubble operating longer or developing a larger version, called the Next Generation > Space Telescope, for launching in the next decade. The Hubble, deployed in 1991, > was designed to have a 15-year lifetime. > > "He's telling us it's O.K. to dream again," said Dr. Michael S. Turner, a University > of Chicago astrophysicist. > > Some astronomers expressed > skepticism. Where's the money? > How can we dream if we do not > have something now to live on > and work with? Where are specific > plans or new institutional > frameworks for transforming > dreams into reality? > > Such reservations might have > been more widespread if the call to > dream again had come from > anyone other than Mr. Goldin. > Since he became NASA > Administrator in 1992, he has > shaken and stirred the agency > more than any previous leader in > the period after the Apollo > lunar-landing project of the 1960's. > > Dr. Robert Gehrz of the University of Minnesota, the president of the astronomical > society, said Mr. Goldin "has been widely praised" for reviving and streamlining > the planetary exploration program and then establishing a new effort, called the > Origins Program, bringing together biologists, astronomers and planetary > scientists to study the newly discovered extrasolar planetary systems for evidence > of life. > > To save a moribund planetary program, Mr. Goldin introduced a new design > philosophy of "faster, cheaper, better" missions, replacing the past reliance on > expensive, multi-purpose spacecraft. These missions took years to get off the > ground, and a single failure often left scientists with nothing. Under the new > program, modest Mars expeditions are setting forth every two years in a sustained > program leading to a return of Mars rocks in the middle of the next decade. > > Three years ago at another astronomy meeting, as observers were detecting the > first planets around other stars, Mr. Goldin announced his vision for the Origins > program. > > "At the time, we didn't have a nickel in the budget for Origins, just a vision that we > might someday be able to search for life on other planets," Mr. Goldin reminded a > group of scientists in another speech 10 days earlier. "Now Origins is funded at $1 > billion over five years. It happened because the scientific community came to > consensus, embraced a vision and pressed ahead with it." > > Asked why astronomers should take his new challenge seriously, Mr. Goldin > replied, "I've delivered every time I've pushed the boundary." > > Mr. Goldin's speech came at an opportune time because, under the auspices of the > National Academy of Sciences, astronomers are conducting a broad review of > research goals and priorities for the next decade. The study, to be completed by > the end of the year, is headed by Dr. Christopher McKee of the University of > California at Berkeley. > > Mr. Goldin conceded that NASA would not be able to count on an expanding > budget to pay for new undertakings. Its annual budget is $14 billion and not likely > to be increased much in coming years. Indeed, its budget is continually under > pressure from cost-cutting Congresses. Of that amount, $2.2 billion is spent on > space sciences, with most of the balance going to human flight programs like the > space shuttle and the International Space Station, now being assembled in Earth > orbit. > > But Mr. Goldin said in the interview that he hoped to increase space science's > budget share. He is also holding discussions with leaders of the National Science > Foundation and the Energy Department to undertake more joint and coordinated > research efforts, especially those combining particle physics and astrophysics to > explore primal mysteries of cosmic origins and evolution. > > Just as he enforced a new design philosophy for planetary missions, Mr. Goldin > said the space agency should reverse its approach to all astronomy programs. In > most cases, he said, the practice has been to plan a mission and then develop the > necessary instruments to carry it out. > > In his speech, the NASA leader recommended that, instead, the agency should > support research on "a continuing line of cutting-edge technology" in imaging > systems, spectrographs for examining light from space objects, lightweight > telescope mirrors, innovative robotics and new, less expensive propulsion > systems. Then missions should be launched as soon as the technology is ready, > and no later. "We cannot suffer from the 'ready-aim-aim' syndrome, which we've > seen too much of," Mr. Goldin told the astronomers. > > With this approach of "just-in-time" technology, Mr. Goldin said, the new > emphasis will be on "fast turnaround times of only a couple of years and costs of > just a few million dollars" for new missions involving new exploring techniques. > By then, sometime well into the next decade, he said it would be time to send the > Hubble and other old observatories "into well-deserved retirement." > > Astronomers "hold tight to older technologies because we are comfortable with > them," he said, but they "consume a great deal of money for maintenance and > updating, preventing us from developing and launching new and improved > systems." Then he warned, "We cannot continue on this path." > > Listening to Mr. Goldin talk, Dr. Turner of Chicago whispered to the person in the > next seat, "He's a street-smart dreamer." > > Related Sites > These sites are not part of The New York Times on the Web, and The Times has no control over their > content or availability. > > Space Telescope Science Institute. > > NASA. > Copyright 1999 The New York Times Company >======================================== > > > June 8, 1999 > > John Paul, at Home in Polish Academia, Defends > Copernicus > > By ALESSANDRA STANLEY > > TORUN, Poland -- In 1543, the Polish astronomer Copernicus sent his > revolutionary thesis on the movement of the planets to Rome with a > poignant letter seeking understanding from Pope Paul III.
