We have finally installed a vacuum chamber that can drop the pressure to 2,500 mTorr (we can go to 500 mTorr) if we need it. That pressure is pretty close to what Discovery will experience in space. I ran the first test with the Engineering model for over six hours. There was no sign of issues with the model. It worked perfectly before, during, and after the test.

Next up, we will be putting the flight model into the rig to test out the electronics before we ship it off for vibration testing. Of course, we need to get the radio and antenna installed for that one.
