SpaceX launching Crew Dragon early tomorrow morning on an uncrewed test flight to ISS. Crewed launch tentatively set for July or August.

Falcon Heavy set for launch sometime later this month. One website says March 7, another just lists it as "March".

Tesla Model 3 now available at $35k.

Telsa has had several profitable quarters, although they have not yet had a fully profitable year.

Musk ought to be banned from Twitter for his own good, but his two flagship companies seem to be functioning pretty well.

Between those two launches is one that I am really looking forward to watching, the Crew Dragon In-flight abort test.... scheduled for May

AIUI, this involves launching a Falcon 9 topped with an unmanned Crew Dragon capsule, then at around Max-Q, executing the abort sequence, where the escape motors fire to drag the capsule away from the booster, then the booster is destructed by the ground crew, and the capsule parachutes into the Atlantic where it is recovered.

Essentially, the mission is deemed a success if the capsule is saved and the rest of the rocket explodes. Should be spectacular

Another flawless launch.

Crew Dragon is deployed and heading for the ISS where it is scheduled to dock at 6am tomorrow EST

Stage 1 was successfully landed on the drone ship OCISLY 900 km downrange (the 35th time they have done so from 42 attempts)

Docking will be streamed on SpaceX's YouTUbe channel at

Yeah, it's awesome being able to see the launches - I liked the floaty Planet Earth.

For those doubters out there who dont see the benefits of a space flight programme, and who thing we should be spending the miney solving problems here on Earth, here is Jim Bridenstine, the Director of NASA talking about those benefits at the post launch press conference...

And the docking appears to have gone smoothly, last big test for this flight is re-entry in a few days time.

Hatch opening will be in couple of hours (its 12:45 am here and I'm not waiting
up for it!).

When they opened the hatch I half expected 'Ripley' to jump up, take off a mask and reveal it was Elon Musk all along.

I watched it dock and just listened for a while and then watched again when the opened the hatch. Good to see but not as exciting as a launch.

I was quite surprised by the hours of extensive testing they had to do before opening the hatch. Then when they finally opened it, they put on masks and breathing equipment before going in, then they took air samples... what a rigmarole!

Do they go through all this hours long procedure every time a capsule docks?

On unmanned vessels, because there's no one to tell them that the air is perfectly good. Also depends on what's inside the capsule. IIRC the cooling systems on Crew Dragon uses ammonia as a refridgerant and the engines use monomethyl hydrazine and dinitrogen tetroxide. All of those are pretty nasty chemicals that don't need high concentrations to cause severe effects.

Managed to take a break at work just in time to watch the splashdown, very nice and the capsule is on its way home, to be put on top of another rocket it will probably blow to pieces.

Only comment I would make is that I would not want to be be an astronaut who has just spent 300+ days in microgravity, now in a weakened physical state, to return to earth and be bobbing around on the ocean for 45 minutes before they get me out.

I hope the capsule has a good supply of sick-bags!

Yeah SpaceX have already said they are looking to tighten that part of the procedure up.
