Next week a group of 40 scientists, government officials and engineers will attend a closed workshop in Boulder to take a first crack at defining science requirements for the "Labitat," as the External Tank Company (ETCO) has labeled its proposed facility. The meeting is sponsored by the University Corporation for Atmospheric Research (UCAR)—a consortium of 55 universities that owns 80 percent of ETCO's stock—NASA and several other cosponsors, including Martin Marietta, which builds the shuttle fuel tanks.

Currently, the tank reaches 98 percent of orbital velocity before being dropped to burn up ...
