In touching tribute to Samsung Note 7, fidget spinners burst in flames

Re: There's an opportunity here

Quite common for RC aircraft/drone battery recharging. They're often rapidly recharged so even more danger of overheating and bursting in to flame.

Blighty's first aircraft carrier in six years is set to take to the seas

Vulch

The 1970s version of Ark Royal had similar clearance on its way out of Devonport dockyard. They always had to set out with just enough fuel and supplies to get clear of the breakwater, then load the rest of the fuel, food and so forth with the aircraft arriving as they headed out into the Atlantic.

FCC: LEO ISPs A-OK

Vulch

Re: FCC?

The FCC approves usage over US territory, Ofcom will decide on use above the UK, similar agencies will decide for their own countries. ITU is, as you said, responsible for managing frequencies and not if operation is permitted over particular areas of the planet.

Elon Musk reveals Mars colony rocket capable of bringing pizza joints to the red planet

Old news

Note this is just a write-up of the presentation Elon Musk gave at IAC in September last year. He has recently announced a follow-up is imminent and will focus more on paying for the project.

Progress has been made, the carbon fibre tank featured in the presentation has since been tested to destruction. It's not clear if the destruction was intended, but that's why you test such things.

Now you can 'roam like at home' within the EU, but what's the catch?

Re: Brexit

Switzerland aren't included in this. The new regulations cover the EEA, which is the EU, Norway, Iceland and Liechtenstein, but not the EFTA. There's still no regulation of charges calling to other EU/EEA countries when you're at home.

BT's Ryan Reynolds helicopter Wi-Fi ads 'misleading', thunders ad watchdog

Vulch

When I were an engineer working at a regional ITV station (back in the days when they actually existed) adverts did get vetted but the regulators only got to see the shooting script, not the finished product. This got us such items as the two apparently identical shower gel ads featuring the rear view of a young lady taking a shower outside a tent on the African Veldt. Turned out the difference was that in the first version run she twisted sideways enough to reveal a nipple, in the second version which got its first airing after the complaint was upheld she didn't. Both versions had been delivered to us at the same time...

ESA astronaut decelerates from 28,800kph to zero in first bumpy landing

Vulch

The Soyuz has done its re-entry burn and is on the way down before it dumps the orbital and service modules so nothing gets to stay in orbit.

You're conflating two incidents in your last paragraph, the Chinese tested an anti-satellite weapon which resulted in a bunch of debris, and the Americans launched a load of copper needles in the 60s to see if they could create a reflective layer for long distance radio comms.

After reusing a rocket, SpaceX tries reusing Dragon capsule for ISS resupply

Vulch

Delay if delayed

The reason for the possible two day delay if tonights launch doesn't happen is down to the departure of one of the Soyuz currently at the ISS being due to return with its crew on Friday.

'Do not tell Elon': Ex-SpaceX man claims firm cut corners on NASA part tests

Vulch

Differing cultures

From discussion elsewhere... They guy is ex-military and his background had him expecting every component, no matter how small and trivial, to have its own serial number and detailed record of testing and use. SpaceX in common with a lot of similar industry only tracks to batch level and does appropriate representative testing. Interpreting, it seems like a statement along the lines of "This box of bolts has been tested" in SpaceX terms means "We've taken half a dozen at random and checked they meet spec" whereas in his terms anything other than "We have checked every single bolt in this box meets spec" is forgery.

SpaceX yoinks $96m GPS launch deal from under ULA's nose

Vulch

Support ship

No currently flying helicopter has the range to do a mid-air recovery of an engine pack from a Cape Canaveral launch if setting off from land. That means a support ship is going to be required on station, and it's going to need a big helicopter to carry the engine pack so it's going to be a big ship. Probably doesn't need to be quite as big as HMS Albion or HMS Bulwark, but that sort of sized flight deck will be needed to hold the helicopter and recovered engine pack.

What went up, Musk come down again: SpaceX to blast sat into orbit with used rocket

Vulch

Next flight but one

SpaceX has a Falcon 9 due to launch on Sunday, it's due for its static fire tonight after two postponements. Recycle the pad and SES-10 is up next. There's a ULA launch due, currently targetting the 14th, and if that slips again (should have launched last week) then it may affect the SES-10 launch.

Elon burning to get Falcon back on the launchpad

Vulch

Re: Back in business

They have no plans to not try for a landing every time from now on, with the possible exception of Heavy centre cores. Barge landings for Iridium and Echostar, probable RTLS for CRS-10, and a barge for SES-10 which should also be the first reflight.

Re: Showing off?

If this being the first Pegasus launch in 3.5 years and only the sixth in the past decade makes it routine...

The low flight rate makes it a very expensive launcher.

Just what Europe needs – another bungled exit: Mars lander goes AWOL

Vulch

Re: "plasma noise"?

"The ground" in this case would be the surface of Mars. Shuttles remained in touch during re-entry by relaying via the TDRS in geostaionary orbit above them. Mars Express and TGO were (hopefully) recording information from the lander for that reason.

SpaceX blast kills Zuck's sat

Vulch

It's up to the customer. Having the payload already integrated means launch can be a day or two (was scheduled for the 3rd) later, static fire without payload means the rocket has to be lowered and taken back into the hanger for it to be fitted and is more like a 4 or 5 day turn around.

Re: slippage

The static fire is also a full dress rehersal for launch. The full fuel load is put on board.

Giant Musk-stick test-firing proves a rocket can rise twice

And again again

The stage has had two more full duration firings since, one each Friday and Saturday. It appears they took Sunday off though. Elon did say they would fire one of the recovered stages 10 times in a row so we may be due a busy, and noisy, week.

SpaceX winning streak meets explosive end

Vulch

Re: @joed

All nine engines on the first stage can gimbal, the centre engine is mounted slightly lower than the outer ones and has a larger range of movement. Steering by differential throttling has been tried by various organisations in the past but is generally too slow for the level of control needed.

At the moment only the three engines intended for landing are capable of being restarted in the air, the other six need ground support to light. Adding restart capability to all of them would be possible but heavy.

Boring SpaceX lobs another sat into orbit without anything blowing up ... zzzzz

Vulch

Re: Musk's goal closer and closer

Turns out there's not much gained by adding extra boosters. The second stage becomes the limiting factor even if you start going disposable on the first stage cores, and if you do that the cost goes up rapidly. And if you're going to redesign the second stage you might as well also build a bigger first stage to match it that doesn't need boosters.

Watch it again: SpaceX's boomerang rocket lands on robo-sea-barge

Vulch

Re: Alien Space Bat at 54:19

It's quite often done by just turning on the engine but not lighting the blue touchpaper. Rotate the stage through 180 degrees so the engine points along the orbit, open the valves and you get a bit of thrust slowing it but without the risk of toasting the expensive payload that has just been dropped off.

Re: "I wonder if JeffyPoooh's happy now?"

All but one of the landing attempts that have been recorded from the air used a NASA aircraft which is only available when it's a NASA flight.

Don't know about the rail gauge, but basically yes. The Soyuz units are shipped in and assembled horizontally as at Baikonour, Peseltsk and (soon) Vostochny, then wheeled out and the payload added when vertical.

Bigelow have launched two inflatable modules already, Genesis 1 was still fine when the electronics failed 2.5 years after launch, as was Genesis 2. Both are still up there and are big enough to be visible when they pass overhead.

SpaceX Falcon 9 grounded by 'sledgehammer' winds

Re: Why super-cooled fuel?

Using denser fuel means the pumps can push more of it through the engine without having to redesign all the plumbing for larger bore pipes. The engines have had an upgrade but not that extensive.
