Looks to be downstream of the Exhaust plume tunnel.

What distance was the camera away?

They can get pretty damn close if they want. They're usually escorted to the site in the morning so they can set up their remote cameras. They're triggered by the sound of the rocket & they can lurk there all day.

This video of how they set up remote cameras was taken at Vandenberg for the recent NASA InSight / Atlas V mission

The entire vertical assembly building rolls back on rails before launch,so they just had to line up on the rocket.

It's a good job they had cameras at the pad, because one of Vandenberg's sea fogs rolled in and they didn't see a damn thing from the viewing area.

Looks like they actually did recover both fairings after all, sadly from the ocean, but I guess they can still be re-used! smile

I wonder how much extra refurbishment they require after a water landing compared to being caught

I would have thought the same?

Agreed - take a few precautions against salt-water corrosion and it could be cheaper to just let them splash down than to go chasing them

It depends on how much aluminium/magnesium content there is. You just don't want those metals immersed in salt water - even for only a few minutes.

They're supposed to be an aluminium honeycomb sandwiched between a couple of sheets of carbon fibre.

SpaceX make their own fairings. They're very err... vertically integrated. wink

I guess the problem is that if they smack into the ocean there could be all sorts of internal damage that would be extremely difficult to detect, let alone repair.


ULA's fairings were made in Switzerland by RUAG, although they've just opened a factory on the ULA complex in Decatur, Alabama.

This will make the 5.4 m fairings & interstage for the Atlas V. One of the first ones:

What happens when you setup your remote camera a tad too close to the pad ?



The memory card survived OK



The final frame

Just read a bit more on this and it was actually damaged as a result of a brush fire caused by the launch - not directly by the launch itself.

My understanding is that they are mostly carbonfibre, based on things Elon has said publicly in the past. $5m a pop too.

They do a lovely piece on them when we’re at the Saturn V launch site, going into detail about Elon’s aspirations to make it all as reusable as possible. Quite an aspiration, but good to be in this part of new history being made

Next F9 launch coming up on Thursday 31st May from SLC-40 in Florida. They completed the static fire earlier today.

This will launch the SES-12 comms satellite and is using a pre-flown block 4 first stage. It previously took up the Boeing X-37B mini shuttle for the US Air Force last September. The first stage won't be coming back this time.

They do have problems with scrub fires at Vandenberg at the best of times and parts of California in general.

They had one at Vandenberg a couple of years ago that burned 4,500 acres.

SpaceX has delayed the launch of the SES 12 communications satellite until shortly after midnight Friday at Cape Canaveral, allowing teams additional time to complete pre-launch vehicle checks and wait for improved weather conditions. The launch, which was previously set for Thursday, is expected around 12:29 a.m. EDT (0429 GMT) Friday

Subtropical Storm Alberto is hitting northwest Florida hard currently. They've evacuated areas of Florida, Alabama and Mississippi as a result.

The weather forecast is marginal for Friday 1st, with Saturday 2nd looking better.

The range was due to shut down on the 1st for maintenance, so they've already given them a day's leeway.

If they can't launch on Saturday, the next opportunity is likely to be Sunday 10th June.
