The Dumbass Lounge>Space Exploration megathread
DaFace 09:40 AM 06-01-2014
Since a number of cool things are happening in space exploration these days, we'll widen the scope of this thread a smidge. Conversation about all things space exploration are welcome, whether it be from NASA, SpaceX, ULA, Blue Origin, or anyone else. Chances are most of the discussion will still be about SpaceX since they love to make things public and fun, but nothing's off limits. I'll eventually get around to modifying the OP to include resources for other companies too, but in the meantime, feel free to post any cool stuff you run across.

Roscosmos is pretty fucked right now, and NASA should be planning on moving forward without Zvezda. Russia has threatened to leave the ISS and decouple Zvezda before. ISS doesn't have it's own propulsion system and uses Zvezda. Apparently station-keeping can also be done via a docked Soyuz' propulsion. Hopefully Crew Dragon and Starliner have been designed to provide propulsion as well.

Looks like all went well. I couldn't bring myself to get up at 6am on a Sunday for a Starlink launch. I'm glad that they've become so kind anew that I don't care, though.

Here's the money shot:

It's sometimes mind boggling the timelines NASA has to deal with. Launch in 2016. Intercept in 2020. Return to Earth in 2023.

RE: OSIRIS-REx, here's a nifty animation that explains wtf it is you're looking at in the video above.

How does the return package, well, return? It must have some form of propulsion and guidance system?

The probe itself stays intact until it gets back to Earth. Once it gets close, the payload gets jettisoned and returns to the surface under parachute.

It's not as exciting when it's a Russian spacecraft, but Chris Cassidy and the other Russians are on their way down from ISS right now. Should touch down in a couple hours.

EDIT: Safely on the ground.
