Genesis Mission Status Update
February 2, 2004
The Genesis spacecraft continues its mission collecting solar wind material expelled from the Sun. Telemetry from the Genesis spacecraft indicates that all spacecraft subsystems are reporting nominal operation.
There are three collector arrays aboard Genesis that are exposed to, or hidden from, the solar wind. One collector array for each of the three solar wind regimes. Which collector array is exposed is determined by the data received by sensitive ion and electron monitors located on the spacecraft's equipment deck. These monitors scrutinize the solar wind passing by the spacecraft and relay this information to the onboard computer, which in turn commands the collector arrays to deploy and retract as needed. Recent solar activity has called for the `low solar speed' array to be deployed 92% of the time. Also, the H-Array, which handles high-speed solar wind was unshaded 8% of the time.
The Genesis team is reconfiguring the spacecraft's rejection grid after a safing event which occurred on Jan. 29. The team will power back on the spacecraft's concentrator with a new, lower maximum voltage limit during a scheduled tracking pass on Feb. 3.
Telemetry from the Genesis spacecraft indicates that it is spinning at a rate of 1.6 rotations per minute. The spacecraft's space age `gas gauge' indicates propellant usage totals are about 20.39 kilograms (45 pounds).
