World Space Congress: CONTOUR Update - No Smoking Gun

On Monday, an internal team of the Applied Physics Laboratory (APL) is
turning over its findings to a NASA troubleshooting team looking into what
went wrong with the Comet Nucleus Tour (CONTOUR) mission. The spacecraft was
lost to space on August 15, shortly after firing its STAR 30BP
solid-propellant rocket motor in order to depart low Earth orbit. That
firing was known to have under-performed. Insiders here at the World Space
Congress say that, as yet, "no smoking gun" has been found regarding why the
spacecraft has failed to respond to Earth commands. However, APL
investigators have made some headway into possible reasons the CONTOUR
mission went astray.

Asteroid Wake-up Call

NASA's Near Earth Asteroid Rendezvous (NEAR) spacecraft sitting atop
asteroid Eros is getting a wake-up call from Earth in December. Whether it
responds is another matter. After circling the space rock for almost a full
year, the NASA probe landed on Eros on February 12, 2001. Carrying out extra
science duties directly on the surface, NEAR was turned off on February 28,
its mission deemed fully successful. Now a signal is to be transmitted to
the spacecraft to see if it responds. Using one of the large Deep Space
Network radio dishes, one sweep of Eros is planned on December 13. While
space engineers attending the World Space Congress admit chances are slim of
getting a peep out of NEAR, a response would show how robust spacecraft
electronics could be in surviving deep freeze temperatures.
