Nice-looking bird. All white rather than the black seen in artists' conceptions, with no markings at all. The one thing slightly surprising about it, to me, was that the trailer it's on looks like it was built to carry 747s -- it's very massive. [Built to handle Pegasus's larger successors?] This Pegasus is complete except that its solid motors are filled with inert ballast rather than live fuel, for captive-carry tests. The tests will mostly check out the old X-15 pylon and Pegasus's adapter (necessary because the attachment points aren't in the same places as those of the X-15); no drop tests of the inert Pegasus are planned. The carry tests will lead up to launch in October. Total development costs up to first launch are estimated at $50M; Hercules/OSC expect to recover this within the first 20 launches. At the moment there are either 2 or 3 firm launch bookings, depending on how you count. OSC expects 2 launches this year and 4-5 next year; the assembly tooling could support 12/year. There is growing interest in launching small payloads, especially as a way to get flight opportunities out of shrinking government budgets. The first payload is a DARPA data-relay satellite and a pair of NASA chemical-release experiments. Launch will occur about 60 miles west of Big Sur, so that Pegasus will be visible to the Western Test Range equipment at Vandenberg. Congress orders DoD to prepare a comprehensive plan for military comsat requirements and programs for the next decade, saying that the Pentagon's comsat architecture is in a "state of complete disarray". House Appropriations Committee staff launches inquiry into the space station, based on suspicions that a lot of the money is not really going into technical development. [What a surprise.] NASA initial FY91 budget submission was for $17G, lowered to $14G after OMB got a first glance at it. The wishlist includes two orbiters, Shuttle-C, the space-station lifeboat, and a large assortment of science missions including Mission To Earth and Gravity Probe B. SDI defers decision on whether to proceed with current plans or switch the main-line effort to something else (e.g. Brilliant Pebbles), pending a major review. Congress expresses some skepticism about SDI chasing fashionable ideas rather than getting its act together. Soviet spysat, Cosmos 2030, explodes in orbit. Believed to have been detonated deliberately after maneuvering control was lost. This happened in low orbit and most of the debris has reentered already. The Soviet spysat programs have been very busy of late, for no obvious reason. Cosmos 1870 radarsat commanded into destructive reentry, after the two-year-old satellite started to fail. A second large radarsat is scheduled to go up next year, and there are hopes of commercial sales of data once the third -- intended as an operational, rather than experimental, bird -- goes up in 1992. STS-28 deploys advanced imaging spysat Aug 8. Satellite is an upgraded version of the KH-11 [i.e. the KH-12? not clear]. This bird is at a lower altitude than the Lacrosse launched last year, and was deployed using the arm, which Lacrosse wasn't. A small secondary payload, developed by JPL and Goddard, possibly for SDI, is believed to have remained aboard; seven other unidentified experiments were aboard. NASA is very pleased that Columbia is back in service, given the demand for shuttle flights. Remaining shuttle missions this year are 34 (Atlantis carrying Galileo, Oct 12), 33 (Discovery with a DoD payload, Nov 19), and 32 (Columbia carrying a comsat and the gear for LDEF retrieval, Dec 18). NASA-industry team reviews options for handling possible space-station budget cuts. Top on the list is cutting the crew from 8 to 4; there are a bunch of other minor things that might be done, but none with any big impact. Ariane 44LP [first flight of the biggest Ariane 4 configuration] booster launches Hipparcos star mapper and TVSat 2 broadcast satellite. [AW&ST jumped the gun a bit and claimed that they were launched into Clarke orbit, which as regular readers know isn't true: Hipparcos's apogee motor refused to fire, to the consternation of ESA's science team.] France approves development of Spot 4, ensuring continuation of the Spot program. The one change made in the project to gain approval was deletion of a multispectral scanner for crop/vegetation work, which would have required substantial expansion of support facilities. Design lifetime is five years, compared to three for Spots 1-3. The spacecraft bus will be the same one planned for Helios, France's military spysat being developed for launch in 1993. Spot 4 should go up about 1994, in time to take over from the earlier Spots [Spot 1 is in orbit and still mostly working, Spot 2 is being readied for launch, Spot 3 is in storage for later launch].
