Abyss Into Eternity: NASA Gropes for the Event Horizon.

Abyss Into Eternity: NASA Gropes for the Event Horizon
Shooting Star? Killer Space Rock? No, Just a Little Stardust
Chinese Capsule is Working Well
ABYSS INTO ETERNITY: NASA GROPES FOR THE EVENT HORIZON
NASA is getting a lot of practice using two spacecraft to probe the secrets of astronomical objects. Last month Galileo and Cassini took a paired swipe at Jupiter. Now the Hubble Space Telescope and the Chandra X-ray Observatory
have pulled a tag-team technique on Cygnus X-1, the first object identified as a black hole candidate, to find evidence that this object has an event horizon. This news was announced Thursday on the final day of the winter 2001 American Astronomical Society meeting.
SHOOTING STAR? KILLER SPACE ROCK? NO, JUST A LITTLE STARDUST
Earth had a small visitor in the early hours of Monday morning. At about 3:15 AM Pacific Time, an object about 5 metres long and weighing roughly 385 kg hurtled 6,000 kilometres above the Indian Ocean off the tip of Cape Horn. This wasn't a near miss by an Earth crossing asteroid. It was the Stardust probe executing a flyby planned by the Jet Propulsion Laboratory.
Dr. Vaughan Clift is a self-confessed "professional coward". This Australian scientist develops medical technology in the U.S.A. to monitor the health of astronauts in space but prefers the 'non-invasive' approach. Jennifer Laing talks to Dr. Clift about his success in developing space-related technologies and future research plans on the International Space Station.
CHINESE CAPSULE IS WORKING WELL
It's been almost a week in orbit, and according to the Chinese Space Agency, the unmanned Shenzhou II capsule is performing well. The prototype capsule circled the Earth 60 times during four days of flight, and performed hundreds of maneuvers to test its capabilities. A successful landing later this week will pave the way for future test flights, and a manned flight within the next two years.
