NASA adviser encourages innovation in space
NASA?s decision to retire its space shuttle program was the result of a realization that it might suffer further catastrophes if it did not develop an alternative space vehicle, expert Dan Heimerdinger ?81 said during a lunch discussion yesterday.In his talk, titled ?The Columbia Investigation and Termination of the Shuttle Program,? Heimerdinger said that the space shuttles, the first of which made its maiden flight in 1981, are not significantly safer than they were when first launched.?We lost the first shuttle, the Challenger, and [then] the Columbia,? he said.
