I had learned from countless experiences in this and other projects that bad news doesn’t get better with age so I immediately keyed the mic on my headset and told Leo, the test conductor running the other testing in parallel, what had just happened. His response twisted the knife in my chest. ‘Yeah, we seem to have lost all spacecraft telemetry just a bit ago.’ NOT a good sign.

We have all been there in one form or another. It doesn’t ever make feel any less gut wrenching.
