ISS Releases Baby Sputnik

illumina+us writes "CNN is running an article about the recent space walk taken by the personnel of the International Space Station. On today's walk the two astronauts 'carried out a 1-foot-long, 11-pound satellite called Nanosputnik, designed for experimental maneuvering by ground controllers.'" The article also has some tidbits on the ISS's gyroscope problems and how the thrusters used to compensate have caused problems for spacewalks in the past.

More coverage

Here's a little more information about TEKh-42 (the technical name). Quote:

[Purpose of Nanosputnik is to support development of satellite control techniques, monitoring of satellite operations, and research on new attitude system sensors and other components.]

Also, space.com has an article mentioning it.

I'm surprised there isn't more coverage. It is a little reminiscent of the latter days of the Apollo program when there was little/no coverage on the press, or to a greater extent the latter days of SpaceLab.

the altitude is not the issue, the speed is. gps is only used until they're within a couple kilometers of docking, then onboard sensors determine relative distances.

Your prize for asking that rare gem, a perceptive question on /., deserves to be rewarded by a (hopefully) informative answer:

Jim Oberg has a good analysis of the problem in an article on an earlier thruster incideny. In summary, a "mystery force" is being applied to the station during spacewalks which torques it and overloads the gyroscopes normally used to maintain attitude control. The Russians think it may be a small leak from the airlock, NASA is leaning more towards venting from the spacesuits.
