TEGA bakeout

Well, it took a little time for the TEGA to analyze the data from the bakeout, but I finally got word. Another 10 percent of water was cooked away from inside the ovens.

We're scheduled to run yet another bakeout test here in the PIT this week, in preparation for three runs on the spacecraft the week after Thanksgiving. TEGA needs the level of water to drop low enough to not interfere with their scans, but that's not completely dry. We'll see how much closer we can get after next week.

The PIT has been quite steady this month. I mentioned some MECA testing in my last post, and we've been doing a lot more since then. We've been running tests to characterize the instrument; getting the focus position of the OM nailed down and understanding the nuances of the wet chemistry cells.

We also have been testing the RA unstow sequences with the lander at different tilt angles and orientations. Everything has been running quite smoothly. Things are looking good for the upcoming ORT.

A native Mainer writes about his experiences as an engineer for the Phoenix Mars Mission, an effort to see if a robotic lander can find evidence that life once existed on Mars.

Robert Bovill was born at Maine Medical Center July 5, 1979. He graduated from Thornton Academy in 1998. He graduated with a bachelor's degree in physics from the University of Maine in Orono, and then went to the University of Arizona for graduate school. He was employed full-time as a test engineer for this Phoenix Mars Mission a year and a half ago by the University of Arizona.
