Such good motivation to want to be an even better programmer / engineer / scientist. So inspiring what mankind is capable of when we work together.

You guys know we are looking for software people, right? http://www.spacex.com/careers

I applied to the same Linux Admin position in Cape Canaveral 3 times over a year that sat vacant, having 14 years of Linux experience and willing to take the ~60%+ paycut. No response ever.

Will we also see the attempt to land the rocket in this stream?

One of the most impressive things about SpaceX (and don't take this wrong, it's not intended as a snark to your comment) is that nobody cares about the payloads any more --- they just work. We just assume that when they launch something it'll get there. Their first ISS mission was in early 2012! That's less than three years ago! That's amazing!

There is no higher compliment for a rocketry company than to be considered boring.

That said... I'm waiting for the first stage landing footage. squee

Could someone explain why it's (apparently) so much harder to land on a barge than it is to dock with the ISS?

I think this calls for a car analogy.

Let's say you're driving along the highway and come up on another car. Try to get behind him and gently nudge his bumper. (Don't try this in real life.) Not too hard, right? That's docking with the ISS.

Now, do the same thing, except he's stopped on a steep downhill slope, and you're going 70MPH. You can use your brakes, but you have to push them pretty hard if you push them at all. If you come to a stop too early, the hill will accelerate you into his bumper. If you start on the brakes too late, you'll hit too hard. You have to time it precisely.

That's more or less landing on the barge, except you also have to steer in two dimensions, and you're coming it at more like 700MPH.

You guys regularly fire some portion (3% to 5%) of your employees every year yes? I love what you're doing and I'd love to be part of it, but the press doesn't make it out like a great place to be an employee. It makes sense I guess, given the risk involved in launching rockets, but this kind of work environment is probably not for everyone. http://www.latimes.com/business/la-fi-spacex-employees-lawsu...

Being fired for low performance is okay — if you feel you're continually perform poorly, you should start to look for another job well ahead of this moment. California is not a particularly saturated market for software developers.

Not following the legally required procedure is bad, though.

At about +1:30 I heard "Recovery platform has acquisition signal" and then: "Stage separation confirmed. Good luck stage 1" and "We have stage 1 boostback startup" then a little while later "stage 1 boostback shutdown" (sounded good) "stage one entry burn has started" then "stage one entry shutdown" "stage one is transonic" "stage one landing burn has started" "LOS of stage one" (From reddit: waiting for stage one co…

If it's successful I hope they'll show a quick replay for stage 1. Probably reasons why they don't want to show it live...

From what I understand, the reason they don't show it live is because they don't have enough bandwidth to transmit live video from the barge. They get a frame every second or two, and lots of telemetry, but not video.
