...actual design of the satellite has not yet been chosen, but its scientific payload--four highly advanced telescopes and a spectrometer--is known and NASA says that the EUV Explorer (EUVE) will be launched by the space shuttle...
...later the crew got down to work, releasing a Satellite Business Systems Comsat, the first of three communications devices to be deployed. The 1,069-lb. cylinder, to the intense relief of everyone involved, went toward its proper geosynchronous orbit 22,300 miles above earth without a hitch: the payload assist module (PAM) used for the launching was the same kind of device that had shoved two satellites into uselessly low orbits last February. A second satellite was sprung successfully on Friday, this one employing the new so-called Frisbee launcher. The mechanism, designed especially for the shuttle, acts...
That expensive steel-and-sheet-metal postscript, the assembly building, shelters the newly assembled spacecraft until it is ready for loading. The job begins in a hulking concrete structure called the Payload Preparation Center, a stationary, 147-ft-high building. There, in a relatively particle-free chamber, the spy satellites and other exotic space gear to be carried aloft will be given final checks in sealed chambers. Explains Engineer O'Gorman: "If we do the job right you should be able to take a transistor radio in there and not pick up a single outside signal." This feature...
Unlike the cargo on current flights, Vandenberg payloads such as meteorological and navigational satellites will not have to be placed in bulky canisters to keep them free of contamination. Instead the devices will be taken into the Payload Changeout Room, Slick Six's third movable building. This 158-ft.-high, 6,000-ton structure moves by rail toward the waiting assembly building, where a mammoth door of six panels, each measuring 30 ft. high and 130 ft. wide, will slowly rise, just like a garage door. Inside the building-within-a-building, the payload will be lifted into...
...calamitous satellite losses. Under the direction of Physicist Ronald McNair, 33, both satellites were spun perfectly out of Challenger's cargo bay. Even so, there could be serious repercussions for NASA and the U.S. aerospace community. Unless the problem with the little boosters, called PAMs (for payload-assist modules), is resolved soon, some upcoming lift-offs may have to be postponed. PAMs are scheduled to be used for satellite launches in May as the upper stage of a conventional Delta rocket and in June during the maiden voyage of the third shuttle, Discovery. Insurance brokers are now warning...
