Room for improvement 1
came up. A lot of people thought this is a terrible thing but we improved the software and so people don't do that anymore but we discovered a susceptibility. Despite the concerns expressed by NASA management at the time, STS-3 was still a test flight - and such problems are commonplace on test flights - as well as only the third mission of the world's most advanced and complex spacecraft. The achievement was that the astronauts identified the problem before the Shuttle went operational and...
Abseiling Into The Spacelab
Preparing Columbia for this marathon mission, which would also become her last long-duration flight for almost five years, was as complicated an affair as the Neurolab experiments themselves. After having been transferred to Pad 39B on 23 March 1998, in anticipation of a 16 April launch, many of her mammalian and aquatic passengers had to wait until the very final hours of the countdown before they could be loaded into their cages in the Spacelab module. This proved an interesting event, worthy...

However, the commentator's excitement-tinged announcement - ''We have ignition and liftoff of Columbia, reaching new heights for women and X-ray astronomy'' -masked a serious problem brewing in the Shuttle's main engines. It came to the attention of Collins and Ashby five seconds after leaving the pad, when they noted a voltage drop on one of their ship's electrical buses, which caused one of two backup controllers on two of the three engines to abruptly shut down. The third engine was...
A Mysterious Flashing Satellite
Considering that STS-28 was such a historic mission, the official announcement from NASA spokesman Brian Welch, a couple of hours after launch, was a flat, businesslike The crew of Columbia has been given a 'go' for orbital operations.'' The primary payload was deployed at 8 06 pm, about seven-and-a-half hours into the mission at the time, John Pike - a space policy analyst for the Federation of American Scientists - speculated that it was a massive 14,500-kg 'KH-12' satellite, one of the...
Rcrs Problems 1
Prior to the first EDO mission in June 1992, exhaled carbon dioxide from each of Columbia's crew members was scrubbed from the cabin and Spacelab atmospheres using lithium hydroxide canisters, which had to be changed four times daily. The new RCRS has already been described, but in case of failures a series of 28 lithium hydroxide canisters were kept in reserve, offering five extra days of science-gathering and two 'contingency days' - in case of one or two 'waved-off landing attempts due to...
A Full Plate Of Experiments
Had Challenger not been lost in January 1986, it is likely that Spacelab-D2 would have taken place some time in 1988, about three years after the D1 mission. The delays in getting the Shuttle back into space, however, pushed it back into 1992 and finally 1993, but the enthusiasm of West Germany - and later the unified Federal Republic - remained intact. ''It is viewed by the general public, as well as the politicians in our government, as a very important mission,'' said Heinz Stoewer, a...
The Revolutionary Tempus
With four times as much time aloft as had been possible on STS-83, the scientific teams associated with both LIF and TEMPUS were gathering so much data that many were confidently expecting to spend at least a year analysing it all. The unique TEMPUS electromagnetic-levitation facility yielded the first measurements of specific heat and thermal expansion of glass-forming metallic alloys and, in so doing, obtained the highest temperature 2,000 Celsius and largest undercooling ever achieved in a...

A Controversial Flight
The inclusion of a veterinarian on the crew had been on the cards before the SLS-1 mission, because, like its predecessor, the second Spacelab Life Sciences flight would involve extensive physiological examinations of 48 male rats Rattus norvegicus , caged in a pair of Research Animal Holding Facilities RAHFs . It would also controversially feature the first-ever in-flight decapitation and dissection of six of those rats this had drawn a significant amount of public criticism, but, according to...
First Spacewalk From Columbia
The other five STS-87 crew members had already been training for six months by the time Kadenyuk joined them in May 1997. Commander Kregel, who flew a year earlier on STS-78 and previously in July 1995, would be joined by Pilot Steve Lindsey and Mission Specialists Kalpana Chawla, Winston Scott and Takao Doi. Of these, only Scott - one of very few black members of NASA's astronaut corps, and one of only a handful to have completed a spacewalk - had flown before his selection for STS-87 was...
Fluid Physics
Remarkably, in spite of their relaxed state, the crew continued to enthusiastically pursue their hectic schedule of around-the-clock research in the Spacelab module. In addition to the crystal growth experiments already mentioned, a wide range of fluid physics investigations were carried out. These examined the behaviour of fluids under different influences, including the application of heat, in the hope that they could one day be used to produce high-technology glasses, ceramics,...
Substitution Iecm Off Pdp On
Luckily, it was on the second day of the mission, when Fullerton again felt ''great'', that he uncradled the RMS for the first of what would turn out to be a marathon 48 hours of tests. Soon after 3 00 pm on 23 March, he flexed the arm's robotic muscles, before returning it to its berth on the left-hand sill of the payload bay four hours later. One problem that cropped up during these tests was the failure of the wrist-mounted television camera which, crucially, would enable Fullerton to view...
First Jellyfish In Space
Another subset of SLS-1 investigations focused on the brain, nervous system, eyes and inner ear and included experiments from a joint US Canadian project to investigate the impact of space sickness on the performance of the crew. One intriguing piece of hardware involved an astronaut placing his or her head inside a rotating dome, which induced a sense of self-rotation in the direction opposite that of the dome's own rotation. The subject then used a joystick to indicate his or her perception...
Columbias Other Passengers
Seven astronauts were not the Shuttle's only living passengers on LMS also hitching a ride were embryos of the hardy Medaka fish, provided by Debra Wolgemuth's team at Columbia University College of Physicians and Surgeons in New York, which were being flown as part of investigations into gravity's role in animal development. At intervals, an onboard video microscope provided television viewers with pictures of the growth of the transparent embryos. It was recognised, said Wolgemuth, that...
Seventh Time Lucky 1
The repeated launch delays did not appear to have diminished the enthusiasm of Bowersox and his six crewmates - Pilot Kent Rominger, Payload Commander Kathy Thornton, Mission Specialists Cady Coleman and Spanish-born Mike Lopez-Alegria and Payload Specialists Fred Leslie and Al Sacco - as they left the Operations and Checkout Building that morning, wearing back-to-front baseball STS-73 crew portrait. Front row left to right are Al Sacco, Kent Rominger and Mike Lopez-Alegria and back row are...
Medical Experiments
Elsewhere in the Spacelab module, the crew - which included two medical doctors Brady and Thirsk and a veterinarian Linnehan - also concentrated on the second complement of LMS experiments the life science investigations. These were further categorised under five disciplines human physiology, musculoskeletal, metabolic, neuroscience and space biology and, according to Victor Schneider of NASA's Life and Microgravity Sciences Office on 5 July, ''the information-gathering has just been...
Secret Mission
With pressure on getting Discovery and Atlantis into space before the end of 1988, Columbia's launch was delayed until July and eventually the second week of August in the following year. However, as STS-28 drew closer, the shroud of secrecy covering it showed no sign of being drawn back. Not until years later would details of exactly what Columbia's crew did while in space begin to trickle out. Leestma, whose previous Shuttle flight had been a scientific one, described preparations for his...
Space Truck
Preparations for the STS-5 mission took place on three separate fronts. Firstly, there was the assembly of the boosters and External Tank, which took place in the VAB. Secondly, there was the processing - and a good deal of modification, too - of Columbia herself in the OPF. Finally, on this first operational flight of the Shuttle, the astronauts would be required to deploy two commercial communications satellites Satellite Business Systems SBS -3 and ANIK-C3. Both arrived by aircraft at Cape...
A Heavy Payload
In such a dire eventuality, Columbia would tip the scales at 113,000 kg, some 590 kg heavier than safety rules determined to be the maximum-allowable landing weight. In the case of STS-93, a one-time-only waiver was granted to this rule, based on a detailed analysis of the payload, the Shuttle's centre-of-gravity constraints and a host of other interrelated factors. For Eileen Collins, the challenge of possibly having to perform a heavier-than-normal emergency landing did not faze her ''We...
