The scientific value of the manned Space Station has been challenged by physicist James Van Allen of the University of Iowa, who says it is "inefficient." In anticipation of a House Appropriation Committee meeting this week, the eight scientists have written to Congressman Jerry Lewis (R-CA), member of the Appropriations Committee. The scientists write, "It is our judgement that NASA's manned Space Station will be of great scientific value in astronomy and lunar and planetary science." The scientists' statement concludes, "The Space Station's combination of scientific uses and commercial applications makes it a highly cost-effective facility with major benefits to the US economy as well as to basic scientific knowledge." The full statement follows: As scientists who have been working in the field of space science for many years, we have concluded that NASA's manned Space Station will be of great scientific value in astronomy and lunar and planetary science and in the scientific observation of the near-earth environment. We want to indicate our strong support for this project on it's scientific merits. In astronomy, we are impressed by the capabilities of the Space Station for orbital repair, refurbishing, and resupply of fuel and cryogenics to costly research facilities including the Space Telescope, the Gamma Ray Observatory and the proposed Advanced X-ray Astrophysics Facility and Space Infrared Telescope Facility. The orbiting observatories are among the most important scientific projects of our time because they may provide answers to some of the greatest cosmic mysteries. Yet they are extremely expensive; the Space Telescope alone cost more than one billion dollars. If the stop working, they will not be replaced in our lifetime. The manned Space Station can make an invaluable contribution to scientific progress by keeping these great observatories in continuous service. The Shuttle also is useful in this connection, as demonstrated by the repair of Solar Max, but the Space Station will be more cost effective for that purpose because spare parts for operating satellites will be warehoused in the Space Station and available for prompt repairs at essentially zero incremental cost. This is in contrast to special Shuttle launches dedicated wholly or partly to repairs, which cost 70 to 80 million dollars each. In addition, prompt satellite repairs from the SHuttle could require scrubbing of planned missions with disruptive impact on scientific and commercial launch schedules. (The repair of Solar Max was planned years before the mission was undertaken.) Finally, major satellite repairs, requiring extended operations in orbit, are feasible from the Space Station but not from the Shuttle. In lunar and planetary science, the manned Space Station can function as a way station en route to the moon and the planets. It can also function as a lab for preliminary processing of samples returned from planets, comets and earth-approaching asteroids. One of the mmost exciting near-term projhects in planetary exploration is the return of a sample of Martian soil to the earth for geological and biological study. If attempted by direct ascent from the earth's surface, this project would require a Saturn-5-class booster, which is not available and not in NASA's planning. If the elements of the mission are carried into orbit in the Shuttle and assembled at the Space Station, the Mars sample return becomes possible. In the longer term, the return to the moon and the establishment of a lunar base for scientific observations holds great promise as a source of major scientific discoveries. In addition, the lunar base itself, once extablished, greatly increases our capability for exploration of the solar system. Again, the lunar base, if attempted by direct ascent from the earth, is not feasible without a Saturn-class booseter, but becomes a feasible goal if the Space Station if available as a staging area for orbital assembly of supplies and equipment. These scientific uses of the Space Station are in addition to its bread-and-butter activities as a repair shop for commercial satellites, a warehouse for stockpiling spare satellites, and a pilot plant and industrial laboratory for orbital processing of materials. Repairs to satellites in the Space Station can save the taxpayer and the private sector a staggering amount of money over the course of a decade, since large satellites cost about 100 million dollars each and hundreds are planned for launch in the next decade. A large fraction of the cost of the Space Station can be written off in savings from satellite repairs alone. This combination of scientific uses and commercial applications makes the manned Space Station a highly cost-effective facility with major benefits to the US economy as well as to basci scientific knowledge.
