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. http://cnn.com/TECH/space/9908/20/nanosatellites/index.html http://www.spaceviews.com/1999/08/20b.html 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. http://www.msnbc.com/news/302468.asp 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. http://www.flatoday.com/space/explore/stories/1999b/082199d.htm http://www.spaceviews.com/1999/08/22a.html 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. http://www.spaceviews.com/1999/08/21b.html To unsubscribe from this newsletter, just reply with only the subject line "UNSUBSCRIBE NEWSLETTER".
