Preparations for HST SM4 Continue at the Kennedy Space Center
Hubble Space Telescope engineers from NASA's Goddard Space Flight Center had a busy week at the Kennedy Space Center preparing SM4 hardware for its ride to orbit on board the Space Shuttle Atlantis. The replacement Science Instrument Command and Data Handling (SIC&DH) unit arrived on Monday. It was integrated onto the Multi-use Logistics Equipment (MULE) carrier.
The spacewalking flight crew arrived on Wednesday for two days of hardware familiarization activities with Goddard engineers in the Payload Hazardous Systems Facility (PHSF). They examined tool stowage locations, inspected interfaces, and practiced spacewalking procedures with flight tools.
They also had an opportunity to participate in the SIC&DH integration activities, something they will have to do on-orbit as part of the SIC&DH replacement task on SM4. The engineers also had an opportunity to see Atlantis arrive back at launch complex 39A. The Hubble payload is scheduled to be loaded into Atlantis on April 19.
