ACEIZE Tracking the current state of Science and Technology

The Indian Space Research Agency reports that Chandrayaan-1 is no longer receiving ground based commands. Chandrayaan-1 has been orbiting the moon and taking pictures of the lunar surface. Sunday attempts to send directional and speed changes as well as camera re-focusing were not received by the satellite.

This communication failure follows on the heels of a sensor issue in mid-July. On July 17th, Chandrayaan-1's 'star sensor' failed. The star sensor was used to keep the satellite correctly oriented in space. Since this sensor failure, the satellite has been using a backup gyroscopic system for orientation.
