This close-up view of “Nanosputnik” (TEKh-42), held by cosmonaut Salizhan S. Sharipov (partially out of frame), Expedition 10 flight engineer representing Russia's Federal Space Agency, was photographed in the Zvezda Service Module of the International Space Station (ISS). This small (5 kilogram mass) satellite, powered by 10 lithium thionyl chloride batteries, will be activated by Sharipov after his egress from the Pirs Docking Compartment and later “launched” into its own orbit during the spacewalk scheduled for March 28. The 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.
