In one year the Orion spacecraft (Lockheed Martin) launches as the Artemis II mission. This will have a four-person crew and is expected to do a lunar (moon) pass by. Why? Artemis III mission (2025) is expected to land on the moon.

Of significance: the Artemis I mission (2022), with the same Orion craft, sustained some unexpected and significant damage to its heat shield on reentry to our atmosphere. Yikes. Nasa said that if they were to redesign the heat shield, the whole program would get pushed back. Bill Nelson, NASA chief, said Artemis launch is still on schedule, so I guess they are gonna go with the shields as-is. But I'll tell ya, looking at that damage there... yikes.

I mentioned Orion's heat shield issues earlier, conflating it with Starliner. Different systems, the Orion solution is multiphase, new to USA ships, and indeed did not meet expectations on its one...flight....test.

Sketchy.
 
Just come back at night when it’s cooler. Or land in Antarctica. Or both.
Lol. There is something they can do without changing the design. They can change the angle they approach the earth's atmosphere. More direct angle lowers the time those shields are heated, which might lessen the effect on those tiles. With a more direct angle, the crew capsule "punches" right through the atmosphere, but this also increases the deceleration on the astronauts. It's traditionally referred to as "g"s. Anyway, it's not pleasant.
 
Chinese rocket company, Deep Blue, looks to compete with SpaceX and the re-usable booster stage. They don't quite stick the landing though (getting close!). FF to the end of this video for the exciting conclusion.

They definitely get a A+ for drone video though - badass. SpaceX could take a tip here. :rock:

 
There is an atmosphere leak in the ISS. It's leaking air to space, and it's getting worse - quickly.

A long, long time ago I did risk analysis in a facility with nuclear material. "Risk" is the product of likelihood of something happening times the resulting consequence. We rated each (likelihood and consequence) from 0 -> 5. So, for example, the likelihood of the hydrogen tank exploding was a 1, but the consequence was a 5 (in fact, there was a day care in the area). So that risk would be a 1x5=5.

When the risk gets over a certain number, it's a problem (and requires mitigation, but that's another story).

Anyhoo, NASA uses the exact same risk rating method. They now deem the risk numbers for this issue 5 and 5, the highest rating. I'm sure they will just airlock off the area with the problem. But this shows why the ISS age is a factor.

Looks like NASA will (hopefully) launch in a week to go check out Europa. Should get there ~ April 2030 (!) to see if it has the "capability to support life".

Yes, the same moon that was forbidden to be landed in in 2001 Space Odyssey.

That moon has been featured in a bunch of movies. I think it's covered with some frozen liquid or gas... they think there might actually be liquid water there under some ice.

The surface temps of any body that far from the sun are really low, way way below freezing. However, it's quite possible for higher temps down deep, and maybe even temps above freezing. The hope is to find that. (then set a nuclear-powered machine in motion to start generating O2 from H20 (humans do not need the other gasses found in our atmosphere, namely Nitrogen).

A 125# person would only weigh 1# on Europa. That should make for interesting times getting around.
 
Yep, ice on top (made of water) and water under it at some depth, is believed. Something about the elliptical orbit causing gravitational tugs that create enough thermal energy to keep it that way.

I'm definitely not too knowledgeable but is what I remember. Has the "building blocks" of life...

This pic was taken two nights ago quite a ways south of my mountain house in Franconia NH. My timing sux as I went up the next morning and I'm back home tonight. Might still catch a glimpse in MA...
