Spoiler!

:(

Roscosmos is pretty ****ed 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.

Oct. 18 Falcon 9 • Starlink V1.0-L13

Launch time: 1225 GMT (8:25 a.m. EDT)

Launch site: LC-39A, Kennedy Space Center, Florida

A SpaceX Falcon 9 rocket will launch the 14th batch of approximately 60 satellites for SpaceX’s Starlink broadband network, a mission designated Starlink V1.0-L13. Delayed from September and Oct. 10.

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.

Oh cool.

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.
