NASA's Heliophysics Team Begins Processing Themis Mission Data

Processing Themis Mission Data to get us hover cars!

From the
THEMIS Mission press release of June 7, 2007

"All stored science and engineering data are recovered regularly with a success rate of nearly 100% across the constellation. The THEMIS ground systems continue to function very well."


From the
THEMIS orbits page:

Stage 1: Injection or “Coast” Phase
2/15/07 - 9/15/07

Right after launch all spacecraft are lined up in the same orbit with a 15.4 Re apogee.


Stage 2: Orbit Placement Phase
9/15/07 - 12/15/07

The orbit placement phase is also called “Dawn phase” because the apogee of the orbits are on the dawn side of the magnetosphere. Probe 1 apogee is at 30 Re, Probe 2 at 20 Re, Probes 3 and 4 at 12 Re, and Probe 5 at 10 Re.


Stage 3: Tail Science Phase
12/15/07 – 4/15/08

In the tail science phase the apogee of the orbits are in the magnetotail. Probe 1 apogee is at 30 Re, Probe 2 at 20 Re, Probes 3 and 4 at 12 Re, and Probe 5 at 10 Re.
