Abstract
Renovation of the space shuttle's external tanks (ETs) for civilian space stations can and should begin by 1990, according to a consensus of scientists and administrators. Their views were presented August 3–4, 1987, in Boulder, Colo., at the Workshop on the Scientific Use of Orbiting Shuttle External Tanks, sponsored by the University Corporation for Atmospheric Research (UCAR).Initial efforts should make use of 6000 ft3 (∼170 m3) of unpressurized volume inside the ET, according to the scientists. The tank is larger than the body of a Boeing 747 aircraft and contains the liquid oxygen and hydrogen fuel that puts the shuttle in orbit. A Memorandum of Understanding signed August 3 by the National Aeronautics and Space Administration (NASA) and UCAR opens the way for exploration of the many uses proposed for the tanks. UCAR is the principal partner in the ET program, which is called Space Phoenix.
