A wonderful gift today at lunch with the Sentinel Mission. At a recent B612 event at DFJ, astronaut Ed Lu saw the two scorched TMA-1 panels (below), and remembered sending them off from the ISS:
“I looked through my photos and I found this picture I took of Soyuz TMA-1 as it pulled away after undocking. If you look at the top you can see my hand and the camera lens reflected in the porthole window. We normally went to an inertial attitude hold before undocking, so unfortunately the Sun is almost in the window making the photo less than ideal, but that’s how it goes sometimes. About 2 hours after this photo was taken, Soyuz TMA-1 (with Expedition 6 onboard) had the sensor failure that forced a downmode to ballistic entry. The thruster panel you have was used to spin up the Soyuz to gyro-stabilize the vehicle (rifle bullet style) so it could make an unguided reentry.”

The inner shell is fiberglass over a composite of ebonite, carbon fiber and glass:
Communication with the Soyuz was lost because one antenna was ripped off during descent, and two more did not deploy. The crew regained communications through an emergency transmitter after landing.
