Except I would say: flight 4 worked fine, why change the configuration and remove the recovery hardware?

The webcast portal is up, looks like they are testing or geting ready to test it.

It's been that way for over an hour, at one point it actually showed a video stream of a frozen counter at T-02:30:00 and then it stopped again.

BTW, anyone know of a good method for recording the stream? Does VLC cut it?

Nope...I believe we've found screen recorders to be the only way in the past.

I have just spent the last hour catching up with the thread from the start and thought I would through in one answer to a question raised way back. Someone was wondering about the use of names like 'Merlin'. Well, if you look at the two engines you will note they are named Merlin and Kestrel. Now, what else do you know of that are named Merlin and Kestrel? If you grew up building Airfix models of WWII British fighter planes, you should immediately know the answer!

CubeSat has three standard weights: 0,5 or 1,0 or 2,0 kg.

Close, but not exactly.

A standard 10x10x10 cm Cubesat should be below 1,0 kg. There are possible Cubesat versions - 0,5, 2 and 3 units in size and weight. 0,5 unit should be below 0,5 kg, 2 unit should be below 2 kg and 3 unit should be below 3 kg. The most popular of course is 1 unit Cubesat with 1kg maximum weight.

Of course, deviation is possible, depending on how close you want to stick to one standard or the other, which is important for Cubesat deployer (there are now several options, some of them allow for different maximum weights).

Well, in addition to being Rolls-Royce airplane engines from the 1930s, they're also two extremely similar-looking birds of prey (like falcons)...

Merlin and Kestrel are the names of two falcon bird species.

And the name of the rocket is..........Falcon

That naming scheme fits in with the LH2/LOX upper stage they are working on, Raptor.

Which just about confirms that they are targeting 02:00 GMT.

Hello everybody,

Can someone recall the parameters of this flight for me ? (orbit altitude and inclinaison, s/c weight)

Thx

pbreed · « **Reply #337 on:** 07/13/2009 10:24 pm »

I hope this goes well.
The timing with respect to the current NASA commission and COTS would be bad for a failure.

Building Hardware is different than building software it takes a bit more work to make it consistent. I hope it is a lesson that Spacex has learned, the 1st stage separation/2nd stage start up looked a bit scary even on the flight that worked.

I'm completely wiped from three days in the desert and get to watch both Spacex and the Shuttle launch within an hour of each other. Needless to say I'm not going to accomplish much this afternoon.

the web cast update page has gone back to "web cast pending"..hope that isn;t a bad thing.

William Graham · « **Reply #339 on:** 07/13/2009 10:28 pm »

Status is back to "Webcast pending--please check back for updates.". That doesn't sound encouraging.
