is The Michigan Daily-Friday, November 13, 1981-Page 7 Columbia's sister ship . waits for June PALMDALE, Calif. (AP) -- When the chips were down, Columbia's half-built sister ship, Challenger, sacrifaced a key data instrument so that Columbia might fly. Challenger could afford it; *ts time for space won't come until June. The next member of the shuttle fleet is due to come lumbering out of its hangar a virtual carbon copy of its sister. Workers at the Rockwell Inter- national facility here are toiling daily over tier upon tier of scaffolding surrounding Challenger - second of a lanned four-ship fleet of reusable spacecraft. ON WEDNESDAY, after a problem in Columbia's data relay system jeopardized its launch, Rockwell workers scavenged two 36-pound units, each the size of a breadbox, from Challenger and flew the cross-county to Kennedy Space Center. They arrived at 9:05 p.m. EST, were installed by 10:30 p.m. and tested by midnight. NASA quickly announced that liftoff was on track, a little delayed. Last month, NASA borrowed 8 *hernial blankets from Challenger' to serve as extra insulation should Columbia require it. Challengers construction hangar, a huge, nondescript building with great sliding doors, is identified by a weather- battered sign as "Building 294." It is on the edge of this desert town 25 miles from the dry Rogers lakebed where Columbia ended its historic first flight On April. DICK BARTON, a spokesman for Rockwell, the prime shuttle contractor, said nearly 700 men and women are working on final assembly of Challenger, and "tens of thousands from nearly every state in the Union have worked on parts of it." There are "no major design changes" betweeen Challenger and Columbia. "There's some fine tuning and of course you upgrade your systems as you go along," Barton said, explaining the only real difference is that systems on the Challenger are designed and verified to last 100 missions, while some Columbia systems were not verified. Columbia will be pulled briefly from service and its systems upgraded once Challenger is on the job, he said. Pieces were made around the country then shipped here, where "everything is put together, with the exception of the engines," which are installed at Cape Canaveral, Barton said. The wings were made on the East Coast, transpor- ted by ship through the Panama Canal to the Port of Long Beach, then moun- ted upright on the back of a truck and taken through Los Angeles to Palmdale at 3 a.m. CHALLENGER must be completed by next summer because it is to fly in 1983. The third and fourth shuttles - Discovery and Atlantis - are at early stages of assembly and will follow at roughly one-year intervals, Barton said. For now, Challenger's six windows are covered with green plastic, as is its open nose. The cargo bay doors are not attached, and workers move about on ladders and catwalks, installing cables, conduits and tubing. Much of the work involves applying the 30,800-heat-resistant tiles - about 50 more than protect Columbia from the heat of re-entry. "At this time I know of no other musical ensemble that combines, as these superlative musicians do, the deep concern, musical perception, and faultless realization of all they play.19 - The Washington Post Daily Photo by JACKIE BELL NATIONAL DIRECTOR of the Americans for Democratic Action Leon Shull criticized Reagan administration policies and offered governmental solutions in his speech, "A Liberal Response to Reagan," at the Michigan Union last night.

We should put a lot more into alternative energy sources and should certainly push conservation." Shull described the ADA, which was formed in 1947, as a political movement that 'reacts to the public agenda rather than sets it. "WE BELIEVE that the gover- nment's purpose is to intervene on behalf of the people. Life is unfair ..- and government is the major available instrument to address that unfairness," he said.

Though he-predicts a discouraging in- crease in unemployment next year, Shull says he is not pessimistic about the future. "In 1982, there will be a fairly sharp turn and the Democrats and the liberals will win some seats back,"' he said. "The American people will see that the economic policies and the entire program is not working and they'll begin to turn against Reagan.''

McLEAISH SAID there remained a chance the mission would be extended to a third day, or a fourth, "bitt the present plan is for a minimal 54-hour mission." The flight, had been scheduled for 124 hours. A 54-hour flight, duplicating Colum- bia's 36-orbit inaugural last April, provides the proper number 'of revolutions to bring Columbia home at the right time and the right spot. Columbia could travel its full five-day r tour on its two working fuel cells, ac- coridng to United Technologies, which manufactured the cells. McLEAISH referred to the two active fuel cells as "alive and well," and he explained: "If the two fuel cells stay healthy, and no other problems develop, consideration could be given to extending that time frame. However, the 54-plan gives the opportunity for moving the highest priority items ahead in the flight plan." The flight plan calls for testing of Columbia's robot arm, the device that will deploy and retrieve satellites once the shuttle passes its test flights and goes operational - expected next year. Truly, in remarks before launch, said "We are still in the front end of a very complicated flight test program. Our mission rules are very consedrvative. If we had a failure and our rules tell us we have to come home early, we will do __ that." The problem was not a life- threatening one for Engle and Truly - or one requiring an immediate return. Still, it was enough to invoke a requirement that "when a fuel cell is permanently off the line, it brings about a mission rule that calls'for a minimal mission." 119111 LII.' 4' E' Ilk I r i rS s * i A ,z I r 01 hr £ihitn 13 tn Kings Productions Auditions UNIVERSITY OF MICHIGAN Michigan Union, Kuenzel Room Dec. 11 2-6 p m.
