A layman's intro to SpaceX, followed by some interesting stuff about computational fluid dynamics. Specifically about applying wavelet compression on GPU hardware in modelling turbulence. They're using it to look at combustion inside Merlin and Raptor engines, and shockwaves during atmospheric reentry.

Sounds like a few billion up in smoke:

Bet Lockheed and the rest were celebrating that one.

Its should be easy enough to find out, if nobody sees it in orbit in the next week or two then it failed to reach orbit

But SpaceX did claim that everything was fine from their end, so who knows what happened

Falcon Heavy launch set no earlier than January 25th. Static fire test of engines later today.

More private Rocketry this time from NZ

World’s first orbital-class rocket launch from a private launch site

Quote:
The Electron rocket is a relatively small vehicle, at 17 meters tall and with a diameter of 1.2 meters. Nine oxygen-kerosene "Rutherford" engines power the vehicle, each with 34,500 pounds of thrust at liftoff. (That is a little less than one-fifth the thrust of each of the nine Merlin 1-D engines that power SpaceX's Falcon 9 rocket). When fully functional, the rocket will be able to send up to 150kg to a Sun-synchronous orbit 500km above the Earth.


What is this, A ROCKET FOR ANTS !!!




The Kiwi rocket reached orbit

As someone who works with a kiwi, there's something very funny about hearing the countdown in his accent.

There has been no delay to SpaceX launches so from their end that launch was fine, it looks to me that this was different to a usual spy satellite and like you say they just want Russia, China ect to think it failed

It looks like the Ariane 5 which one of the most reliable launchers just had a failure, it happens to them all eventually

Launch imminent. Let's hope it succeeds. Musk seems to think the odds are 50/50.

Phenomenal achievement.
The two rockets landing together was a truly spectacular sight.

Forward to 9m 17secs.

Looks like they lost the centre core

I think they would have took that result before the launch

Another view of the returning boosters. Cool delayed bang from landing burn ignition.

It was truly amazing.

Who could watch those two boosters landing together and not think we have made a huge leap forward into the future.

The core not landing was like loosing the cherry from the cake. No doubt SpaceX will learn what went wrong and make the next one better. As Musk says “if you are not blowing stuff up, you’re not trying hard enough”

Not confirmed but apparently the Centre core came in hot and suffered some damage to a Grid fin so it lost some control authority. It slammed hard into the sea about 100m from the drone ship and knocked out two of the drones 4 thrusters and spread debris over the deck. TBC

Awsome just Awsome. I almost shed a tear.
