Kepler Recovered from Emergency and Stable (nasa.gov)
Here's an exciting update on NASA's Kepler, which entered "emergency mode" last week. An anonymous reader points us to a press release on NASA's official website: Mission operations engineers have successfully recovered the Kepler spacecraft from Emergency Mode (EM). On Sunday morning, the spacecraft reached a stable state with the communication antenna pointed toward Earth, enabling telemetry and historical event data to be downloaded to the ground. The spacecraft is operating in its lowest fuel-burn mode. The mission has cancelled the spacecraft emergency, returning the Deep Space Network ground communications to normal scheduling. Once data is on the ground, the team will thoroughly assess all on board systems to ensure the spacecraft is healthy enough to return to science mode and begin the K2 mission's microlensing observing campaign, called Campaign 9. This checkout is anticipated to continue through the week. Earth-based observatories participating in Campaign 9 will continue to make observations as Kepler's health check continues. The K2 observing opportunity for Campaign 9 will end on July 1, when the galactic center is no longer in view from the vantage point of the spacecraft.
Given all the troubles the Kepler craft has encountered, I just want to raise a toast to the geeks in charge of this project. They have overcome some incredible obstacles through ingenuity and determination, and yet again they have brought the bird back under some semblance of control... from seventy-five million miles away. Now THAT is a hack.

What OS is this craft using?
Is there a standard OS NASA uses on all it's space born computers? Or, is everything written from scratch?
Anyone know where you can read about the code, or even read the code?
