Genesis Mission Status Update
May 23, 2003

The Genesis spacecraft continues its mission collecting solar wind material expelled from the Sun. Telemetry from the Genesis spacecraft indicates the spacecraft is in overall good health and as of the morning of May 23, the spacecraft was about 1.25 million kilometers (.77 million miles) from Earth.

Recent solar activity has called for the "high solar speed" collector array to be deployed 53% of the time and the "low solar speed" array deployed for the remaining 47%. 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.

The Genesis team completed an in-flight test of the spacecraft's battery. The team's battery experts will be analyzing the data over the next few weeks. Preliminary indications are that the battery has not "aged" as much as was expected.

The latest series of computer commands for Genesis were uplinked on Friday, May 16th, and went active last Tuesday, May 20.

Genesis Vital Statistics:
- 654 days since launch.
- 316 days to planned completion of solar particle collection.
- 473 days to Genesis return to Earth.
