October 5: “WE LUCKED OUT ON THAT ONE,” CRIPPEN SAYS
Mission officials say that damage to Atlantis’ rear engine compartment was minor and should delay the Defense Department launch only a day or so. “We’re still continuing inspections, but thus far we have not found anything that I would consider significant damage,” said Shuttle Launch Director Robert Sieck. “We lucked out on that one. We did not get any significant damage,” said Shuttle Program Director Robert Crippen.
An investigation is underway to find out why a steel beam was left inside the compartment. Sieck said, “You can’t see more than two feet in front of you in there before your line of sight is blocked by something. This beam was left in a very obscure area. Most of the damage can be repaired in place. In the worst case, you would have to remove small pieces of structure, lines or wires.”
Launch is still targeted for November 7. “There were a couple of lines that had some minor damage,” said Crippen. “At this time, it appears that none of the problems caused by that will have any impact on the launch.

October 6: BACK IN THE AIR AGAIN – AND THERE’S MORE TO COME
The launch of Discovery STS-41 from Launch Pad 39B this morning at 7:47 a.m. EDT broke a string of setbacks for NASA. “It’s good to be back in the air again,” said Launch Director Bob Sieck. Sieck said he was optimistic that NASA’s next mission – Atlantis STS-38 in early November – would proceed as planned. Officials have located and fixed Atlantis’ hydrogen leak and do not expect major damage from a 70-pound steel beam accidentally left inside the orbiter’s engine compartment when the craft was hoisted upright for mating. NASA continues to look for the source of Columbia’s leaks. “We’re going to find and capture this diabolical leak in Columbia and get her back in the air this year,” said Sieck.

October 9: COLUMBIA AND ATLANTIS DODGING TROPICAL STORM KLAUS
Yesterday NASA added a new maneuver to its Space Shuttle program when it completed its first “rollaround” of Columbia from Launch Pad 39A to Launch Pad 39B. Pad 39A had to be cleared for the November launch of Atlantis STS-38. But due to adverse weather conditions stemming from tropical storm Klaus off the east coast of Florida, Columbia was on the roll again today; the STS-35 stack was safely back inside the Vehicle Assembly Building by 8:00 this evening. Blustery winds and rain showers are predicted in the KSC area for the next few days and winds are forecast to be gusting up to 40 knots. Power-on stray voltage tests are underway today on Atlantis and a test of the SRB actuators is planned. Atlantis is currently scheduled to be rolled out to Launch Pad 39A no earlier than October 11.

October 9: IT WAS SO BIG THEY JUST MISSED IT
Simple oversight by three workers for Lockheed Space Operations Co. is the explanation NASA gave today as the reason why a 9-foot yellow beam was left behind in Atlantis’ aft engine compartment. “It was so big they just missed it,” said Conrad Nagel, Atlantis’ ground processing manager. “I know that sounds funny, but that seems to be what happened. It’s like the guy who was stealing tractors from the warehouse. They’re so big the guard didn’t question when they were being driven out.”
Nagel was unsure whether the incident would affect Lockheed’s shuttle processing contract at Kennedy Space Center. “They are embarrassed by this. We all are. It never should have happened. I hope it will never happen again,“ Nagel said. Lockheed, which has not yet submitted its final report to NASA, declined to comment. (Brown, Florida Today, Oct. 10, 1990)
October 9: RIDDLE IN THE SKY
A U.S. spy satellite believed to have been destroyed following deployment from Atlantis in February 1990 has been spotted in orbit by three amateur astronomers, according to a report in the Florida Today newspaper. The sightings indicate the $500-million photo reconnaissance satellite, deployed by Atlantis STS-36, is carrying out its mission of spying on the U.S.S.R in an orbit 500 miles above Earth. Ted Molczan, a Toronto satellite observer reported locating the assumed-dead satellite and posted his findings on a computer bulletin board sponsored by the Canadian Space Society. A Scottish astronomer, Russell Eberst, and Frenchman Pierre Neirinck confirmed the sighting of the satellite.
These reports contradict accounts of a Soviet news agency which say the satellite disintegrated in space and fragments fell to Earth over the northern region of the Soviet Union. The U.S. Department of Defense stuck to its story that only “hardware elements” carried into orbit by Atlantis re-entered Earth’s atmosphere between April and July. The newspaper story said the amateur astronomers believe the satellite probably began maneuvering to a new station March 7, the same day the Soviet reports detected four falling orbital fragments. The falling objects were probably unessential satellite parts being discarded. (Countdown, December 1990 – edited)
October 10: ATLANTIS GETS READY TO ROLL
The Shuttle Interface Test on Atlantis has been completed. Today, workers will power down the vehicle and begin closing out all areas for the move to the launch pad. Tomorrow, platforms will be retracted away from the vehicle and the crawler transporter will be positioned under the launch platform. Weather permitting the vehicle is currently scheduled to be rolled to the launch pad tomorrow evening at 8:00 p.m. EDT. While at the pad, a liquid hydrogen tanking test is planned to verify there are no leaks. (KSC Shuttle Status Report, Oct. 10, 1990 – edited)
October 11: SPACE DEBRIS BECOMES A REAL RISK
The risk from space debris is becoming real, warned a report released today by the Office of Technology Assessment (OTA). Shuttle flights and other space activities could become too risky if space-traveling nations continue to scatter low Earth orbit – below 1,250 miles – with junk, the report says. The U.S. Space Command lists 6,645 objects in low Earth orbit fast-moving enough to pierce spacecraft such as the planned Space Station Freedom and the Soviet station Mir. Only six percent of the objects tracked are functional satellites and the rest is made up from spent rocket boosters, exploded satellites and satellites that are no longer in service.
The only documented collision of debris and spacecraft was in 1983 when an orbiting paint chip damaged the windshield of Challenger. Such a chip could puncture the suit of a spacewalking astronaut, the OTA report says. Suggestions presented by the OTA to remedy the problem include designing boosters so they won’t break up; hardening batteries against bursting; and reducing the altitude of spent upper stages so atmospheric drag will bring them down.

October 12: ARIANE V39 LOFTS TWO AMERICAN COM-SATS
Arianespace, Europe’s commercial space transportation company, successfully launched two American satellites into space from their Kourou, French Guiana space center at 6:58 p.m. EDT today. The Ariane 44L launch vehicle, with four liquid strap-ons, carried the SBS-6 and Galaxy VI satellites for Hughes Communications Inc., of Pasadena, California. SBS-6 will be used for telecommunications broadcasts and Galaxy VI’s mission will be video and news-gathering transmissions. This was the first launch of two satellites owned and built by the same company aboard a single launcher. The mission was the 39th for the commercial Arianespace program begun a decade ago.
