Did you know that how we experience time is not obvious?

In 1962, explorer Michel Siffre descended 130m underground. He had no #time cues with him.
He repeated the exercise several times with other people.

He discovered that with the absence of light, humans adjust to a 48h (instead of 24h) time cycle.

He had been inspired by #space travel & #astronauts confirmed his findings.

His last expedition covered New Year's Eve 2000, but he overslept by 4 days.

Splashdown!

They're baaaaack!

Adam Frank to Ari Member:

If you're a space nerd, like I am & they are, being in space is like being in Hawaii. It's like going to Hawaii for a week and then getting told, no, you're actually staying in Hawaii for several months.

The idea of these #astronauts being stranded in space is not the reality - they got to enjoy being in #space longer, do more #science - that's more just politics.

How to Astronaut An Insider's Guide to Leaving Planet Earth by Terry Virts, 2020

This book is a collection of essays, each one on a different subject related to spaceflight. Some short, some long. Some technical, some emotional. Some fact-based, and some purely speculative. Some funny, some tragic. All are written with two goals in mind: to make you laugh, and to make you say, “Wow!” Often.

Why #LBJ Canceled #Apollo #Moon Base
#NASA's requested funding was spent on Great Society, including building rapid transit system in several cities. Funding allocated elsewhere than NASA transformed American society in other ways. NASA intended for #astronauts to live on moon for two weeks. For comparison, Neil Armstrong and Buzz Aldrin spent 21hr on the Moon during Apollo 11, costs ultimately derailed the lunar base.Johnson administration had other spending concerns.

Elon Musk Loses It After Astronaut Dares Calls Out His Lie

#ElonMusk called a famous astronaut a slur simply because he countered one of his newest talking points.
newrepublic.com/post/191782/el

“What a lie,” Danish #astronaut Andreas Mogensen wrote... in reply to #Musk parroting the talking point yet again on #FoxNews. “And from someone who complains about lack of honesty from the mainstream #media"

Musk exploded."

#Astronauts 👨‍🚀 travelling to #Mars would encounter #radiation ☢️ levels higher than humans have ever experienced, and be exposed to them for much longer.

To protect them, the #spacecraft would either have to be much bulkier, making launches expensive and difficult, or be made of more efficient #shielding 🛡️ materials. skyatnightmagazine.com/space-m
