Live rocket launch

Did the retro thrusters fire for the crew capsule? Looked like a hard landing to me...

I did wonder that myself.  I'd assumed that we'd see some flame and/or disturbance of the dust on the ground before the actual landing, but I saw neither.

I made a rocket like SN8 when I was about ten years old.  I can understand why SpaceX may be having a few problems today.  I had terrible trouble getting the tin foil to stick to the cardboard tube.

Not sure if anyone else interested in this sort of thing, but in about 30 mins there's a live launch here: http://www.ulalaunch.com/webcast.aspx  

I know this is a couple days ago now, but I thought I'd share this on here. On the second orbit of the Soyuz MS-18 launch I was able to listen in on the voice communication from the Russian cosmonauts

No doubt 'Mannakin Skywalker' will have something to say...

One of the hazards of the job if you're a crash test dummy 😄

Bit worrying as this rocket is supposed to carry tourists! It isn't a test rocket like the previous one.

On NASA TV today:

Jan. 16, Saturday
4:20 p.m. – Artemis Fires Up: Live coverage of the hot fire test of NASA’s Space Launch System (SLS) rocket core stage, from Stennis Space Center, Mississippi

That's 4:20pm eastern US time according to NASA, so 9:20pm UK time I think.

Nice big windows so they'll get a lovely view even if it's their last one 😄

Short and sweet, not to mention noisy !

I guess they will be poring over all the data they got now.

I wonder what the local wildlife makes of it ?

All the “smoke” is actually steam and water vapour from all that water from the sound supression system that prevents damage to the rocket from all that adoustical energy and the exhaust cooling system.so not a problem for the local wildlife.

Looks impressive though. 👍🏻

From NASA

More than 32,500 5/32-inch holes in the B-2 stand flame deflector will direct more than 240,000 gallons of water a minute to cool engine exhaust during a test. Another 92,000 gallons of water per minute will be sprayed through 92 nozzles to provide vibro-acoustic suppression protection to the core stage during testing. This also will help shield the stage from radiant heating and other thermal effects.

I think the noise is much more of a problem for nearby animals than the steam, it is enough to do physical harm. I do feel sorry for the seagulls flapping past rockets just before ignition.

Realised this evening that I missed the Space-X Transporter 1 launch yesterday.  Fortunately it's still on the Space-X website.

There's a lot of waffle at the start.  If you just want to join for the ride, fifteen minutes in is a good place to start.

If anyone else does watch, at 20:38 have a look for a white crescent-shape thing that appears on the left hand side of the frame and disappears off the edge of the shot of the first stage.  Blink and you'll miss it.  Is that part of the fairing falling back to Earth do we think?

This?

Reckon you could be right.

It's on the first stage image more clearly I think.  It's barely there for a second though, so I've not managed to get a screen grab yet.

Wasn't even looking at the first stage :)

However, now I am, I think I see it but not clearly. There's something that looks like a flash behind one of the left gridfins. 

Got it on quarter speed trying to get a grab of it now

I can't see it at all now.  Not what I saw before, anyhow.  I should have screen grabbed what I had at the time.  The other fairing half does seem to go through the shot around 22:21 though.

Here we go:

About a third of the way up the left hand side of the screen, just coming into view from behind the first stage?  It looks as though it could actually be fairly close.

Timing. :)

Downloaded from YT. Ran through VLC Frame buffer to output the frames, upscaled to 200% and made a GIF. I reckon you're right.
