Reply to comment by KAugsburger in In 1971, three cosmonauts Dobrovolski, Volkov, and Patsayev passed away due to a valve malfunction in the Soyuz 11 capsule. They remain the only people who have passed away above the Kármán Line - the defining line of space. by sciencekenyon

So they must've been forced to let the air out of their lungs out, or rupture of lungs? Terrible way to die, seeing life get sucked out of you and your mates

Reply to comment by Waddensky in How come space probes generally take photos of moons or asteroids from several hundred (or thousands) of kilometers away from the object they orbit? by Different_Muscle_116

Okay Juno took photos of Io some of which were from several hundred to a thousand kilometers away.

I assume that IO has less gravity well than Earth. There are objects even smaller than Io that have had photos taken from orbits as well.

I always wonder why they can’t orbit closer and get even greater surface detail.

I’m basing an assumption that an object with less mass (like an asteroid or a moon) can be orbited much closer than a satellite around the Earth before the gravity well becomes an issue.

Are these missions at their absolute closest orbits possible given the fuel reserves?

Reply to comment by oalfonso in Earth's inner core may be slowing down, but “Nothing cataclysmic is happening,” says Hrvoje Tkalcic, a geophysicist at Australian National University. “The inner core is now more in sync with the rest of the planet than a decade ago when it was spinning a bit faster.” by clayt6

"Some," yes, but almost certainly nothing we'd notice. The core is still spinning, it's just the differential between the crust and the core that has decreased.

Reply to comment by farticustheelder in Mycotecture — the use of mushrooms and other fungal substances for architectural purposes — could be key to building affordable, fire-resistant, insulated habitats on the Moon and Mars. NASA aims to experiment with the technique on the Moon in 2025. by clayt6

As Shakespeare might put it:

There are more reagents to this organic chemistry, Horatio, then are stored in your moon rock.
