[For the benefit of those who haven't been paying attention :-) and have complained because I don't always explain abbreviations, CRAF is Comet Rendezvous / Asteroid Flyby and AXAF is Advanced X-ray Astronomy Facility. I get very tired of typing the full names every time. (These are the top items on NASA's new-start wishlist, so they get mentioned a lot.)] Future of SDI's proposed quick-and-dirty heavylift booster for its Zenith Star space laser experiment is unclear, because people are accusing SDI of really wanting it as an early-SDI-deployment booster. Space station pressurized modules will not be built to a standard diameter. The US diameter will be the biggest that will fit in the shuttle, the European diameter will match that of Spacelab to permit reuse of equipment, and the Japanese would like to use the US diameter but their ground- transportation facilities can't handle something that size, so they will use an intermediate choice. [Just when you think you've heard the worst possible screwups, a still bigger one comes along...] Albert Gore (Dem. presidential candidate) comes out in favor of an international manned Mars mission and of "reversing the imbalance" in funding between DoD's space budget and NASA's. Pictures of the latest SDI Delta mission, being readied for launch. NASA will run out of space-station money by the end of Feb, and cancel the four prime contracts [!], unless NASA either gets its act together on leasing SII's Industrial Space Facility (Fletcher says NASA has no need for it [!]) or Congress relents on its insistence on this as a condition of station funding. So far NASA is firmly saying "no". As a result, there is talk of moving control of a government-leased ISF away from NASA. Congress says it cannot approve the large NASA funding boosts requested by Reagan unless, under the administration/Congress budget compromise, Reagan takes the money out of something else. NASA sets August as new STS-26 launch target, with Aug 4 the tentative specific date. This puts final stacking in early May, rollout in mid-May, and flight-readiness firing in mid-June. Various minor problems have turned up, but none seem unmanageable. Reagan sends new space-leadership proposals to Congress, but postpones release of the new Space Policy until a commercial-space-initiatives review is complete. The new commercial initiatives will include yet more pressure on NASA to lease ISF as an interim pre-space-station step and limits on third-party liability insurance required for commercial space activities [now THAT is an important initiative]. GE Space Division signs with Martin Marietta to launch 15 commercial comsats on Commercial Titan. This is 7-8 launches. The probable result is price breaks for GE customers due to the volume deal. [Only in space would an order for 8 of something count as "volume", sigh.] This is not yet a cast-in-concrete binding agreement, but it's solid enough to have cancellation penalties. Rockwell and two ex-Rockwell managers charged with fraud over Navstar contracts. As recommended by Langley, NASA will smooth the ends of the KSC shuttle runway to reduce tire wear on landing. Progress 34 tanker docks to Mir. SDI cancels its big in-space neutral-particle-beam experiment due to shortage of money. Japan and NASA sign agreement allowing NASA to receive data from Japan's ERS-1 earth-resources satellite (launch 1992). Big set of articles on DoD's space recovery program, notably Titan 4. Long-term plans call for two Titan 4 pads on each coast, for redundancy. DoD establishes space test-range organization to coordinate all orbital testing activities. Previously such organizations had to be assembled on an ad-hoc basis every time a major space test was planned. Eventually the organization may have its own satellites for tracking and/or data relay. USAF studies proposal from Rowan Companies of Houston to use its "Gorilla" mobile drilling rig as an offshore launch platform for heavylift boosters. Building new pads at Vandenberg is hard because of all the regulatory bureaucracies that have to be placated first. An equatorial site has been thought about, but building it would be costly. Transferring big rockets to a floating platform would also be tricky. The "Gorilla" would be towed into a loading facility at Vandenberg, would jack down its legs until it was resting on the bottom, and would then pick up a mobile launcher platform on a sort of giant forklift. It would then retract its legs, be towed out to sea, extend its legs again to provide firm support, and extend the launcher out over the water on the forklift. After final checkout, the crew would evacuate and the launch would be done by remote control from the shore. One big asset: it would use existing launch-control facilities. Main problem: security and logistic problems of launching from a mobile platform. NASA is also interested. SDI alters two of its midcourse-sensor-satellite projects to cut costs. Space-nuclear-power programs are in trouble because of SDI budget cuts. Article giving more details about proposed projects, not very interesting. GAO expresses some doubts about some of the projects, too, saying that there are major technological challenges in the programs as now conceived, and that there is a lack of specific applications. (They do note the chicken-and-egg problems involved here: specific applications are reluctant to commit to unproven technology.) McDonnell-Douglas to deliver first operational in-space laser communications system this summer, for a military inter-satellite application. (There have been earlier projects for laser communication in space, including one for the NASA Advanced Communications Technology satellite, but all were cancelled.) JPL studies lasers for deep-space communications; one study suggests a transmission rate of 700kbps from Saturn with about a watt of laser power. [This is lots better than radio systems.] Letter of the week, from Lannon Stafford (Phoenix AZ), criticizing AW&ST editorial that called for NASA to control US space activities: "Enduring exploitation of space will occur only under the banner of free enterprise and individual activities, which NASA (or any other government agency) cannot control and can only hamper with intervention... devotion to government handouts and control still seems very difficult to cure..." -- Those who do not understand Unix are | Henry Spencer @ U of Toronto Zoology condemned to reinvent it, poorly. | {allegra,ihnp4,decvax,utai}!utzoo!henry

Pardon my ignorance, but what is scheduled to go up on the August fourth launch? Mike Walma

To answer your question about Discovery's payload - STS-26: According to GODDARD NEWS, November, 1987, the primary payload will be the TDRS-C satellite.
