The Falcon 9 rocket is being fueled with kerosene and liquid oxygen propellants for launch at 6:05 p.m. EST (2305 GMT), but upper level winds could be a problem.

Yup frown High level winds would exceed structural limits

They still have a Dragon splashing down in a couple of hours though

They also mentioned that the gimbal limits of the rocket motors would have been exceeded i.e. the rocket motors would not have been able to cope with the deviations in flight path caused by wind shear.

It would have been difficult to explain how they had launched a rocket into space and "missed".... ;-)

You don't want your gimbal limits to be exceeded. You might end up parking the lot in downtown Palm Beach.

The launch is on again for tonight, but no barge landing due to heavy seas and problems with one of the barge's 4 engines.

They'll try to 'land' it in the sea instead. sonar

The recovery part of the mission has been cancelled - the sea's too rough to land the rocket on the barge

Better luck next time spacex. Gonna be very cool when you get this right!

Great shot of the fairing being jettisoned. I can't remember ground cameras picking up a shroud coming off before.

Next shot afik is using up all the fuel so no recovery attempt then either

Another tweet from Elon Musk:

"Rocket soft landed in the ocean within 10m of target & nicely vertical! High probability of good droneship landing in non-stormy weather."

Well that's good to hear. Pity about the bad weather scupppering the barge landing attempt though. I wonder how many more barge landings they'll need to do before they trust the rocket enough to land back at Cape Canaveral.

With the ULA sabotaging the downrange radar every time they've got good weather, they may never get one. </tinfoilhat>

Isnt there enough open space around to just land it somewhere that isnt close to anything else? Surely there is? Or is it just incase it misses by a mile or two?

Way to early to allow a landing on land.

They've also got to consider an abort or breakup somewhere else in the flight, which would scatter debris for miles downrange. That's why they launch from the coast - even then a boat downrange can prevent a launch as per the last Orion test.

I suppose so.... but there are alot of really empty flat places around, but some aren't suitable launching from Florida.

Either that or an uninhabited island somewhere? Surely Mr Musk owns a Tracy Island like bond villain lair given his wealth? ;-)

The trajectory of the rocket is determined by where in space it is headed. There isn't a huge variation in how the ascent flightpath can be changed - in that there is virtually none. This will be the major determinant as to where they can try and land a 1st stage as it falls back from 30-40 miles up.

Yeah good footage. I wish they'd followed the booster as it did its return burn, but I know they're not likely to do that for a good while.
