Terra Mission Status Update

Status Update Archive

June 8 - 14, 2007

Terra spacecraft and instrument subsystems are in nominal operations.

Terra spacecraft clock error jumped from -23° to -50° on May 31, 2007 and continues to have the -27° offset. Clock error is still within requirements. Anomaly investigation is ongoing.

The Terra ASTER SWIR Cryocooler completed a third week back at the 6mm compressor stroke length. The detector temperature continues to rise at the typical slope. Using this drift rate, the detector temp max will reach 83K on 6/26/07 and the detector temp average will reach 83K on 7/5/07 at which point the first science impact begins on bright scenes. A amplifier gain adjustment is being considered.
