He has a lot of external stuff on his suit I'm worried at Mach 1 it will be torn off.

Not as likely as it sounds. There has been at least one case of a SR-71 pilot ejecting at speed/altitude and making a "safe" ejection, and without everything being torn off. It all depends on the dynamic pressure which is a combination of speed and air density.

How much bandwidth do 5.4 mio viewers consume? Can someone give me a number?

Multicast requires all the intermediate routers support it, I thought. Is that really the case? I can't imagine big routers at ISPs allowing multicast.

Besides proving our thoughts on what happens to the human body going through the speed of sound, there's an aspect of safety as well. If successful jumping at 120,000 feet, that means that NASA could deploy these same space suits as an exit plan for astronauts in an emergency.

>that means that NASA could deploy these same space suits as an exit plan for astronauts in an emergency. What? For exit plan you need a way to slowdown astronaut from orbit first.

I don't think he was saying 'from orbit.' He was saying in an emergency.

Yes, the heat from re-entry is caused by the slowing of the spacecraft's relative speed from the incredibly fast speeds of orbit, as gravity gains hold of it and pulls it even faster. If someone exited a spacecraft in space, with zero drag, and headed towards earth, they would be moving at faster than their terminal velocity and would likely burn up.

But if someone had an issue in a sub-orbital flight - or on takeoff for a space mission - bailing out could be a viable option.

(Interestingly, this is why Col. Kittinger made the jumps he made with Project Excelsior in 1960 - to test whether an astronaut with no skydiving experience in the upcoming Mercury space program could successfully escape their spacecraft in the event of an emergency during the ascent.)

To Red Bull: fix your coverage next time! Your website and Twitter feeds weren't really ever carrying the latest information pre-launch, and your blog was 24 hours out-of-date whenever I checked. (Also YouTube was buffering, it wasn't my connection). Bit of a mess from the PR-masters imo.

There were three HD cameras on the capsule, streaming video down to ground control, and from there onto YouTube and millions of viewers.

It's the fucking future, and noone is appreciating it.

It's definitely not full multicast. Flash doesn't support multicast (if I recall correctly).

They're probably doing a single stream to CDNs which then fan them out.

That might not be necessary... won't atmosphere provide enough lateral braking too? Either way, that's easier to do and requires far lesser equipment and prep than a re-entry capsule.

The lateral braking provided by the atmosphere causes objects to burn up.

Just cover the suits in ceramic tile.

For everything we do to astronauts, why not give them some skydiving experience?

Does someone know the reason behind the poor quality of audio coming from Felix? You'd think they had the resources to put in a decent microphone, and data transfer -- judging by the high quality video -- shouldn't be a problem.

I often wondered about a possibly connected thing about airplane pilot's microphones: Why is it that pilots, when addressing the fliers over intercom always have terrible sound quality? You'd think that airlines could afford a high-quality microphone considering the cost of the plane and the pilot's time. Air traffic control should appreciate quality audio as well. There could be some ruggedness requirement to these…

Some planes sound fine. Airlines just don't care. The in cabin intercom is not the same feed as the ATC feed.

At first glance, skydiving from 10k feet and 100k feet seem like they wouldn't be any different. I'm sure there are intricacies that make the jump very difficult, but it seems like you just let gravity do the work, and the chute automatically deploys for you. Can anyone help me understand what the intricacies are? EDIT: nevermind, seeing him spin but regain control removed my doubt of the difficulty.

Air temperature and pressure are much different at the higher altitude.

Is that a diver challenge or a suit challenge?
