Astronaut Eugene A. Cernan's View From And Of The Gemini-9A Spacecraft During His Extravehicular Activity

Imagine doing full-body stims in weightlessness in outer space

Two astronauts asleep on Challenger’s middeck, August 9th 1983 ‘On Challenger’s middeck, Commander Richard “Dick” Truly and Mission Specialist (MS) Guion Bluford sleep in front of forward lockers and port side wall. Truly sleeps with his head at the ceiling and his feet to the floor. Bluford, wearing sleep mask (blindfold), is oriented with the top of his head at the floor and his feet on the ceiling.’

Basically, there's an alternate universe in which Kathy's selection was blocked, and Blue Origin ended up being the primary contractor, with maybe SpaceX being a secondary contractor for later heavy cargo missions.

It's genuinely possible that Starship HLS might not be ready before Blue Moon MK 2 is.

I love listening to Apollo transcripts! I can’t wait!

New results from our Juno mission suggest the planet is home to “shallow lightning.” An unexpected form of electrical discharge, shallow lightning comes from a unique ammonia-water solution. ⁣

⁣It was previously thought that lightning on Jupiter was similar to Earth, forming only in thunderstorms where water exists in all its phases – ice, liquid, and gas. But flashes observed at altitudes too cold for pure liquid water to exist told a different story. This illustration uses data obtained by the mission to show what these high-altitude electrical storms look like. ⁣

Understanding the inner workings of Jupiter allows us to develop theories about atmospheres on other planets and exoplanets! ⁣
