Testing Einstein's Universe

WEEKLY HIGHLIGHTS FOR WEEK ENDING 3 JANUARY 2003:

PREPARATIONS CONTINUE FOR SV PAYLOAD TEST
The team continued to prepare for the E-28 payload test at the space vehicle level. Support equipment fabrication for the gas management assembly and probe/dewar operations were carried out during the past week. The dewar will be filled with liquid helium to approximately 70 % full prior to starting the payload test. In addition to the payload tests, software verification tests and limited tests will be carried out on the space vehicle. Two anomalies associated with the PDU and ACE units are being worked in parallel with the space vehicle activities.
