The launch of MGS is the first step toward establishing an international robotic infrastructure at Mars.

WorldSpace's $750-million investment in a digital radio broadcast network is expected to make its first profits 2-3 years after launching the startup company's three spacecraft in 1998-99.

ASTRONOMERS FROM Johns Hopkins University and the Space Telescope Science Institute have discovered what they believe is a thin oxygen atmosphere on Ganymede, the largest of Jupiter's 16 moons. The team studied ultraviolet observations of Ganymede made with the Hubble Space Telescope's Goddard High Resolution Spectrograph. It showed that the moon probably has an atmosphere with pressure comparable to Earth's atmosphere at several hundred km. altitude--roughly the level of space shuttle orbits.

NASA has formed a five-man incident investigation board to study the loss of the NASA/McDonnell Douglas DC-XA experimental rocket on July 31, when one retracted landing gear leg caused it to fall over and burn after a successful touchdown (AW&ST Aug. 5, p. 22).

NASA is carefully removing human space flight control from the proven realm of custom software and massive mainframe computers and bringing it at long last to the flexible world of networked workstations.

The Galileo spacecraft is set to release its Jupiter atmospheric probe on Thursday.

Uzbekistan defense officials have proposed incorporating a formerly classified satellite-tracking site into the U.S. space surveillance network, which could improve capabilities to detect orbital debris.
