More details forthcoming later this year. They have to focus on docking with the ISS right now.
There is a webcast right now and I think they are going to fire up some rockets
Just completed a Static Test Fire -- basically emulating launch day, except they don't let go of the rocket, and then shut the engines down after 2 seconds of full-thrust operation.
There was one unplanned hold at T-27 seconds, they eventually recycled to T-20 minutes and did it again, successfully the second time. If that happened on launch day, it would have required a bump to the next available day for launch (instantaneous launch window, no room for unplanned holds or aborts/resets.)

another delay ...
Better to do it right late, then wrong on time.
oh yes! Plus its better if it's a software glitch rather than a hardware one ... usually much simpler to fix.
Sadly I sorta expected it. Luckily for them, it's sort of the norm in this field. Makes you wonder why they always seem to get caught last minute. Pushing deadlines or just poorer earlier testing?
This stuff is just plain hard. The level of automation they are attempting is fairly ambitious, even if it weren't floating in space.
How do you thoroughly test a complex hardware/software system when you have to simulate everything about the environment? Even the simulators are complex.
No doubt they'll keep testing it right up until the flight, which is just another more realistic test.
I'd chalk it up to extreme caution: If ANYTHING looks the slightest bit off in the final count-down, they abort. Maybe a parameter has to be within 2% and it's off by 2.01%. Just my guess.
Maybe the post-analysis of the launch abort on Monday, found that something could be done to make sure it won't happen on the actual launch day?
Where's Khrushchev pounding the desk with his shoe?! :biggrin:
In all earnest, I am happy that careful testing takes priority over rushing the launch. This is a good indicator of how Elon runs SpaceX. With the Model S launch this summer a similarly daunting task, I guess he takes comparable approach to avoid problems.
@SpaceX: Question for @elonmusk? @borenbears is hosting a Twitter chat with him at 2 pm ET. Use #APSpaceChat to ask questions
That is in 30 minutes.
Tweet from Elon:
"Almost done reviewing Dragon code with @NASA. Looks good so far. Target launch date is May 19, right after Soyuz docks."
Tesla could take some design hints from SpaceX. That's what a cabin should look like.
Just to be clear, that's the inside of the ISS. They'll use the robot arm to grab the Dragon capsule.
Ah yes. The Dragon capsule has no pano roof. :biggrin:
And how many years would it take to learn how to drive it?
need moar buttons!
