NASA spokesperson Ken Aitcheson told In Orbit that there were two main, btt minor, problems at the moment. The first is the Reaction Control System — the array of tiny thrusters which control the roll, pitch, and yaw of the shuttle. Here a leak in an inaccessible place has had engineers feverishly trying to work out a way of plugging it without rolling Discovery off the launch pad. more follows > Buzz Index 610 Buzz-Line 619 LATEST OFFERS FROM GRATTAN SEE 193 Buzz Line Rock/Pop Video Reviews Kids

One, developed by the Johnson Space Centre (and called the "clam shell") involved "an external approach" while the other, from Marshall space engineers, involves an external approach and an internal "plugging of the line". Both, Ken added, could be done on the pad and would leave the shuttle launchworthy. more > Buzz Index 610 Buzz-Line 619 Buzz Line Rock/Pop Video Reviews Kids

Information about the sluggish closing of this valve caused the computerised controller to stop a crucial countdown five seconds before engine firing earlier this week. Aitcheson said the problem could either be with the valve itself, with the sensor used to monitor it, or with the software interpreting the data. more follows > Buzz Index 610 Buzz-Line 619 Buzz Line Rock/Pop Video Reviews Kids

NASA people are trying to be philosophical about the c——jn of mishaps afflicting the shuttle. "They're just gremlins, that's all", I was told. "We've got new people, and ground equipment that hasn't been used before. You expect these problems. We're still thinking of a launch sometime in September." more > Buzz Index 610 Buzz-Line 619 Buzz Line Rock/Pop Video Reviews Kids

US and Canadian scientists have discovered ten planet-like objects orbiting distant stars. The US team at the Smithsonian Astrophysical Observatory have found an object 20 times the size of Jupiter orbiting star HD 114762, 90 light years away (and too faint to be seen by the naked eye). more > Buzz Index 610 Buzz-Line 619 Buzz Line Rock/Pop Video Reviews Kids

The most obvious data showed a Jupiter sized planet orbiting the star $—v Ceti. Both teams used the Doppler effect, by which light frequencies alter with movement, to spot "wobbles" in the positioning of stars. This wobble, they suggest, can only be caused by a nearby body — like a planet. more > Buzz Index 610 Buzz-Line 619 Buzz Line Rock/Pop Video Reviews Kids

What the discoveries do mean, say the Victoria astronomers, is that more than half the stars in the galaxy have planetary systems — a very hopful sign for those who would like there to be someone else out there. Don't expect to see these planets. "Seeing them would be like placing a speck of dust in front of a 1,000 watt bulb and trying to see it from miles away" said one scientist. more > Buzz Index 610 Buzz-Line 619 Buzz Line Rock/Pop Video Reviews Kids
