NASA WORKING ON NEW CONSTELLATION OF PROBES

NASA engineers are developing a new series of spaceprobes, each the

size of a birthday cake. The fifth in NASA's New Millennium program,

the spacecraft are designed to launch as a bundle, and then separate

and fly in formation gathering scientific data. An initial launch of

three satellites is planned, but a future bundle of 100 is in the

works for a launch in 2010.

SPACECRAFT COULD HARNESS SOLAR WINDS TO LEAVE SOLAR SYSTEM

Thanks to a $500,000 grant from NASA, researchers at the University of

Washington are developing a new propulsion system called M2P2 (Mini-

Magnetospheric plasma Propulsion), which would allow spacecraft to travel

almost 300,000 kph. The theory is based on creating an electromagnetic

field around a spacecraft, which would interact with the solar wind,

accelerating it away from the sun.

SHUTTLE MISSION CONSIDERED TO RESCUE WAYWARD SATELLITE

NASA is considering a shuttle mission to rescue the stranded Orion 3

telecommunications satellite. Launched into a useless orbit in May,

Orion 3 is still completely functional, and could be relocated into

a higher orbit by attaching a new rocket motor. Shuttle launches cost

$450 million, however, and NASA is considering the overall cost-benefit

of such a rescue.

NEW brown dwarf DISCOVERED

Astronomers using the European Southern Observatory's New Technology

Telescope (NTT) have discovered a faint brown dwarf - named NTTDF

J1205-0744. The object is the faintest and most distant brown dwarf

ever discovered, and it walks a very fine line between star and planet,

with a surface temperature of only 700 degrees celsius.
