ORT 6

Well, the latest round of Operational Readiness Tests/Training is over and we finished with moderate success.

The aim for this round was nominal operations, meaning no one was intentionally causing hiccups to test the science team's ability to react. This all centered around a sample delivery to TEGA. That didn't happen. The trench came out beautifully, with multiple layers and different colors; brown, red, brown, yellow and brown. This may not sound interesting, but very few people knew about this, and the team was able to get nice color images that match up very nicely.

From that trench, the RA was able to acquire a sample and get into position to deliver to TEGA. But twice, as TEGA was prepping to receive the sample, it faulted. So last week was dedicated to debugging this issue. It only took a day, but we figured it out. Current limit was set too low, a change from the default that someone made. Quite embarrassing. But we were able to test both sequences from the ORT and show that both worked. Or would have, anyway.

Stay tuned as I have some other stories from the ORT. If you have a question about any aspect of the ORT, please ask. It's a fascinating look at Mars Mission operations.

RA? TEGA? ORT? What do those initials mean?

ort=operational readyness testing
Thermal and Evolved Gas Analyzer (TEGA).
Robotic Arm (RA)


This blog is best when you give technical insight but you do have to take into account that we are laymen....perhaps PPH could include a glossary as a sidebar. Good stuff.

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.
