Launch
ESSA-3 was launched on October 2, 1966 at 10:34 UTC. It was launched atop a Delta rocket from Vandenberg Air Force Base, California. The spacecraft had a mass of 132 kilograms (291 lb) at the time of launch. ESSA-3 had an inclination of 100.9°, and an orbited the earth once every 114 minutes. Its perigee was 1,383 kilometers (859 mi) and its apogee was 1,493 kilometers (928 mi).
gollark: It is, at least, kind of funny.
gollark: Also they're entirely reliant on the city for electricity and water and stuff.
gollark: Context: you can't really grow food on tiny bits of soil on cardboard. You can't really grow much food on the tiny plots. You can't grow food fast enough for it to be useful in your "commune" in the middle of a city. You probably can't grow enough food *at all* in that area to feed the sort of population density cities typically have. You definitely can't really do it without much farming equipment and by just making a few tiny soil bits with plants in them.
gollark: Yes, exactly.
