Preparing the spacecraft for fairing installation.
Preparing for Launch
This week, a number of significant milestones were achieved at Vandenberg Air Force Base in preparation for launch.
The final pre-launch electrical test of the Aquarius instrument was performed on 24-May. The test was successfully completed and all telemetry was nominal.
On 27-May, the feed covers were removed from the instrument and a final contamination-control inspection was performed to confirm that the Aquarius instrument meets all of its cleanliness requirements; with these feed covers removed, Aquarius is configured for launch.
On 28-May, the fairing was installed around the Aquarius/SAC-D observatory.
