...Vasily Tsibliyev, Mir's commander. Stressed out is probably more like it. Like the Mir spacecraft itself, Tsibliyev is worn down and in danger of falling apart. He has been aboard the aging space station since February and has had to cope with nonstop crises: a fire, breakdowns in oxygen and cooling systems, a collision with a cargo ship and last week a power failure. No wonder he's suffering from an irregular heartbeat and taking sedatives...
...damaged after Mir collided with a cargo ship in June. Once the plug was pulled, the station began to spin chaotically, turning away from the sun and draining its already low energy supply. Crew members huddled in Soyuz, where independent life support and power systems are stored, breathing oxygen from its emergency canisters. As usual, Russian space agency officials insisted that all was under control and said that the crew had not been ordered to prepare for an evacuation. Now that the crew has managed to reconnect the power cable, Mir is reorienting towards the sun and recharging its near...
...samples and fed them into the miniature biology lab, where they were analyzed for signs of growth, metabolism and respiration, processes that would signal the presence of living microorganisms. In one of the tests, a soil sample dampened with "chicken soup"--a nutrient broth--gave off a burst of oxygen. In another, unexpectedly large amounts of carbon dioxide and carbon monoxide were released. While both results produced flurries of excitement at J.P.L., scientists eventually--though reluctantly--concluded that the gases resulted not from life processes, but from some exotic Martian chemistry. Their conclusion was bolstered when neither lander detected...
...reviewed 86 separate studies about the association between soot and dust particles and human illness. The agency was already thinking about tightening its rules on ozone, a noxious form of oxygen produced in the burning of fossil fuels. (Another fossil-fuel combustion by-product, carbon dioxide, is a greenhouse gas, responsible in large part for the phenomenon of global warming.) It reviewed an additional 186 studies on ozone, making this, according to Browner, the most extensive scientific review undertaken for any air standard the EPA has proposed...
...with repair equipment finally docked with the crippled space station. Cosmonauts needed the supplies for the repair work they'll do during a spacewalk July 17, when they will reconnect power lines with the station's damaged Spektr module. Also delivered today: the world's worst airline food, some oxygen, fuel and a toothbrush for American astronaut Michael Foale...
