- Video from Sierra Space of the Tenacity Dream Chaser tow tests
Posted last week, but I think it shows the tow tests done in November 2025. As I noted then, these tow tests should have been done years ago, not after final electromagnetic, telemetry, and vibration tests. There is something wrong here that Sierra Space is not telling us.
- On this day in 1966, the USSR launched an adapted Voskhod spacecraft carrying the dogs Veterok and Ugolyok
The mission lasted 21 days — the first such long term flight — and returned the dogs alive, though in poor health. They had lost weight, but more important was the discovery that weightlessness caused a loss of bone density.
- On this day in 1969, the Soviet Union attempted the first test flight of its giant N-1 rocket
The launch was a failure, as were the three that followed.
