Fake news. Mr Steven is back home in LA. There's a Falcon 9 due off from Vandenberg on 10th Feb, so it'll likely be doing whatever a spider boat can for that. Seeing footage of it catching a fairing at sea, on the run, will be almost as amazing as seeing a rocket land.

Yes, that was kinda the point. silly



In other news, SpaceX is said to be targeting a 6-hour window from 12 pm Eastern (5 pm UK time) on Wednesday for the Falcon Heavy test fire. Do not hold your breath.

How are they getting the fairings to the ship? Surely boosters would be too heavy, after all, a fairing should just be a light cover to protect the payload during launch. I'm surprised the fairings are so expensive that designing and building the recovery capability into them and the ship is financially viable to be honest, the ship itself must have cost a fortune, even just to operate.

4 million dollars of carbon fibre and tech.. Well worth saving.

They will have thrusters and a parachute/wing .

Fairings are a bit more than 'just a light cover' - they have to be strong enough to withstand huge dynamic pressure while also protecting the payload from acoustic damage.

And at £6million a pop they are worth recovering

Coordinating the position of Mr Steven so it's roughly in the right place and calculating where the fairing is going to 'land' so the two coincide is mind-boggling really.

The last few hundred metres of it's descent is going to be very interesting to watch.

Cheers guys, I didn't realise they were quite that "Gucci". I think, as someone said above, the recovery of these fairings will quite a sight.

Impressive and a satisfying amount of steam and smoke too. Made a nice mushroom cloud by the end.


Allowing for the sound delay you can hear the staggered start as they lit a pair of engines every 120-200 milliseconds or so.

From zero to all 27 engines in a couple of seconds.woohoo

That's impressive - considering they only fired the engines for three seconds.

They also seem to be deflecting the exhaust in just one direction. I expected that the exhaust plumes would be split, like on the Space Shuttle.

As rocket aficionado Scott Manley pointed out, "The last time this many rocket engines fired on a single vehicle was the N-1 and we all know how successful that was."

The giant Soviet N-1 moon rocket had 30 engines on its first stage and all 4 launches ended badly.

I timed it at about 12 seconds long. The SpaceX footage they tweeted is edited.


The south exhaust was blocked off, or it would mess up SpaceX's Horizontal Integration Facility at the bottom of the ramp.

Oh my.

The noise.

The steam and smoke.

The POWER.

soon to be, hopefully, SPEED AND POWER.
