GPM Completes Spacecraft Alignments
After a holiday break, final tests for the GPM Core Observatory resumed on Dec. 30, 2013, with alignment measurements. The spacecraft's instruments and components, such as star trackers and thrusters, are attached to the main body in specific configurations. Spacecraft alignment measurement is analogous to alignment for the wheels of a car. The Core Observatory measurements ensure that no parts have shifted during its transportation from the United States to Japan, so they will work as expected.
