Terran 1: Relativity Space's 3D-printed Rocket

[kuririn]

Polling completed.
All systems go.
Very dramatic.

Had to look up this term:
Autogenous pressurization is the use of self-generated gaseous propellant to pressurize liquid propellant in rockets.

 

[kuririn]

Hold at T-1:09.

 

[kuririn]

A boat entered the area downrange!

 

[aerostadt]

Some body is in a boat in restricted waters holding the launch at T-71 seconds.

 

[kuririn]

Boat cleared, new launch time being calculated.

 

[Funkworks]

T - 70 resumed.
Edit: Launch in 20 sec.
Edit: Abort.

 

[kuririn]

Terminal count resumed.
T - 60 seconds.

 

[kuririn]

Whoops.
Looks like one of my rockets.
Ignition then cutoff.

 

[kuririn]

 

[aerostadt]

Engine abort at t-1 second. They are safeing the booster now.

 

[kuririn]

Looking at recycling for another attempt.

I tuned in just in time to see the abort. Hopefully they can try to push the button again. What was the ultimate cause of the scrub the other day? I didn't catch the details...

 

[kuririn]

Don't they have to figure out what criteria was violated before another attempt?

A valve was wonky and the propellant got too warm.

 

[kuririn]

They have reset the clock and are counting down again!
T - 44 min and counting.

 

[Funkworks]

Alrighty then!

T - 38 again

 

[kuririn]

Alrighty then!

 

[Sooner Boomer]

One more chance today. Hope all goes well for them!

It's a pretty good design when you can fire the engines, abort, then re-try an hour later.

 

[Funkworks]

Definitely a creative one.

...

Oh ... scrub. Window closed.

 

[aerostadt]

Here we go !

 

[Sooner Boomer]

Another scrub

That's all for today

 

[kuririn]

Scrubbed.

 

[aerostadt]

Scrub for day. Sad.

 

[bobby_hamill]

I wonder how much it costs them to remove the propellant and add it back for new launch attempt ?

Had to look up this term:

That’s a nice feature of LNG. As you draw down the tank, you can cycle a bit of warm gas back in to keep the pressure up.

I saw at least one SpaceX launch where they lit a Falcon-9 and it immediately shut down, then flew it later in the same launch window....so what they were trying is not without precedent. I was out flying so didn't get a chance to watch. Will be looking for the next attempt.

[kuririn]

Scheduled for a launch attempt today.
Part 3.

 

[Sooner Boomer]

Launch scheduled for 10:00 pm Eastern
