The fact on if
"The fact SpaceX has been tightlipped on if this indicates something was amiss."
Sentences? We've heard of them.
SpaceX has finally fired up the engines of the Falcon 9 that is tasked with carrying the company's Crew Dragon spacecraft on its demo flight. The Merlin engines fired for around three seconds by our reckoning (the video is below for those bothered enough to count), which is a little shorter than usual. Static fire test …
>>>[Launch] date could easily slip deep into March if the ISS partners get twitchy about SpaceX's Demo-1 mission turning up at around the same time as a Soyuz and, er, a SpaceX cargo Dragon.<<<
I can't think of any good reason why they would get twitchy, short of 2 arriving at the exact same time.
Soyuz will arrive > dock > be there for months
Cargo will arrive > dock > be there for as long as it takes
Demo-1 will arrive > hopefully dock > be sent back fairly soon after.
These can happen in any order.
is the usual amount for the full test of the falcon 9.. they'll stick cameras up the engines and review the engine data... but as its a reasonably mature rocket now, they'll know where most of the bugs are.
Just depends on when they've done the review plus can get a lunching slot.
