The Great Ongoing Space Exploration Thread

Here a few hours later I don’t know where it landed. Other than, just like Powerball wins, it didn’t land on me. :wink:

Minor problem with Psyche mission. Drop of pressure in xenon feed line.

Russia is using tanks from WW2 in Ukraine but sure, build a nuclear power plant on the moon.

Seems like a Chinese project where they let Russia tag along, like a small child “helping” to make dinner.

I dunno, I guess Russia probably still has some nuclear and space expertise left, even if their agencies are in rough shape. Maybe they can contribute knowledge if not much else. Maybe they can just ship all their research notes from when they were actually building nuclear reactors in space.

Landing on Mars, according to CNBC:

It’s like one of those pictures from a kid’s book where you have to figure out how many things are wrong with it.

I’ll play!

  1. The astronaut is standing lethally close to a landing/launching rocket.

Starship flight 9 currently on for 05/27/2025 6:30 P.M. CDT

It’s a Crew Dragon

…with the trunk still attached

…with landing rockets inside the trunk?

And apparently no landing gear. Just plops down like all my Kerbal Space Program landers. Who needs dead weight?

Also the rocks and dirt would be flying everywhere, not gently puffing around the immediate area

And yeah, don’t stand that close!

Also, what’s up with the astronaut’s weird R2-D2 boots? And what’s the other thing that you can barely see behind the guy’s legs?

I think that’s the barely-seen legs and an elbow of another astronaut.

  1. That’s an Earth sky and clouds.

Looks like the livestream starts at 5:50 CT:

Let’s hope they fix the upper stage issues!

They won’t be catching the booster, and in fact are letting it impact the ocean at fairly high speed to guarantee it’s destroyed. However, it is a mostly reused booster, which is pretty cool.

What’s the purpose behind that– too worn out to be worth reusing? Or they want the extra boost for the upper stage?

I think they’re doing some aggressive testing of the various burns, maybe with some engine-out tests. Not worth risking the tower on that, especially since the booster is obsolete.

An incredible article on the Max Plank Institute For Astrophysics website about the latest research concerning a boiling surface on Betelgeuse. The article has a wonderful video at the bottom simulating the boiling surface of the star and it seems difficult to believe.

The boiling bubbles can be as large as Earth’s orbit around the Sun, covering a large fraction of Betelgeuse’s surface. They rise and fall at a speed of up to 30 km/s, faster than any crewed spacecraft.

NB: this is a year old now, but am just discovering it.

A potentially new type of object has been observed, or at least one that challenges our understanding of objects. It is throwing out both radio and x-ray emissions at regular 44 minute intervals.

the radio and X-ray emissions appear perfectly synchronized, both following the same 44.2-minute cycle. This coordination suggests the emissions originate from magnetically linked regions within the system, pointing toward an object with highly ordered magnetic fields.

Scientists have proposed several explanations, but none perfectly accounts for all observed properties. The object’s 44-minute period places it firmly in the “death valley” of stellar physics - a region where conventional models predict radio emission should cease entirely.

Probably a Borg hailing frequency.

Someone’s playing a real-life version of Outer Wilds.

Carrier frequency for subspace communications?

If it were 33 minutes instead of 44, it’d be a Cylon hailing frequency.
