Surprisingly, this is actually real. It's known as the Rosette Nebula (Caldwell 49) is about 5,000 light-years distance from Earth, 130 light-years wide, & has a mass ~10,000 × the Sun |

Sometimes I think Russia's space program is run by a bunch of half-trained chimpanzees.

It is, but my understanding is that this was the Russian military and not Roscosmos. Would not surprise me if Roscosmos learned of it the same time NASA did.

I read about this the other day and thought it was interesting.
https://www.cnbc.com/2021/11/09/spin...ve-rocket.html It essentially puts a payload in an enormous vertical centrifuge, spins it to hypersonic speeds, and then throws it up into space. I'm curious how something like a satellite could hold up to those forces, and I'd think that's a hard sell. But if you want to move a bunch of steel or uranium into orbit, this seems like a good way to do it. You really want to be sure this baby releases on the vertical part of the spin cycle, though, or you're going to rip a big swath through Albuquerque.

It's hard to believe, but there's actually a good chance that JWST gets off the ground in a few weeks. Definitely one of the highest-impact (and highest-risk) missions we've seen in a while.
