RealKerbal3x Posted August 20, 2020 Share Posted August 20, 2020 (edited) LabPadre has a thermal cam now... Edit: NSF's latest video. I wonder if SN6 will static fire with or without its mass sim?

As the ship is moving it might well pull the fairing of the net damaging it and the ship. They fish up the parachute afterward. Not sure if they are reused but the parachutes takes no damage from seawater unlike the fairings with their acoustic tiles and many systems where the separation system is the most critical Quote Link to comment Share on other sites More sharing options...
Meecrob Posted August 20, 2020 Share Posted August 20, 2020 23 hours ago, magnemoe said: you can offset this however starting burning while horizontal will increase your horizontal velocity and you have to counter that, so you want to tilt before burn. Now the safe way to do this is to do it high up so you have more time to correct, yes now your landing burn uses more fuel. have extra fuel in the tanks no issue using it once its settled. Yes it an offset weight but its just good training after all. I would move some methane up in the nose as you get the fuel for an abort system, have an secondary header tank downward as you will return stuff from space down the line. What I am saying is the act of changing attitude puts you off course no matter when you do it, and you will need to expend fuel to compensate. Using engines to minimize this transition time will then put you less off course. I very much doubt they will purposefully tanker more fuel for "good training". SpaceX has shown that they aim for high accuracy, not bringing enough fuel to fix being off-course. I agree they will utilize the header tank in the nose, but because that moves the CofG towards the nose enabling a faster attitude transition, not for abort purposes.

RealKerbal3x Posted August 21, 2020 Share Posted August 21, 2020 All the Starships (and a test tank): The thing they're building at the launch site is still not a water tower. Quote Link to comment Share on other sites More sharing options...
kerbiloid Posted August 21, 2020 Share Posted August 21, 2020 (edited) The video, 10:00. The man, walking behind the tractor and holding the section of the near-future reusable rocket with a piece of rope with some green bags on it, looks rather futuristically... The future was never such close before. Upd, Or maybe it's the CORD. The Cord. Like the N-1 CORD.(КОРД is actually CORD, not KORD.

Yes, but you can adjust for this with experience, best is to aim a bit before the landing zone and then delaying canceling out horizontal velocity until just above the LZ, it don't matter then during the landing burn you do this. Using the engine to rotate add horizontal velocity you then has to cancel it out, on the other hand as you tilt into landing position you drag is reduced so you will fall faster but still se no reason to start the engines before you are mostly pointed downward. On Mars you probably have to do this anyway because the low density. Also the first belly flop tests will probably be slower and also doing an longer landing burn as they are verifying the models.

zolotiyeruki Posted August 22, 2020 Share Posted August 22, 2020 What are they hoping for with SN6's 150m hop that they didn't get with the previous hop? It seems like "same song, 2nd verse" to me. Or is it just practice? Quote Link to comment Share on other sites More sharing options...

In general, they want to figure out how not to have so many holds. Quote Link to comment Share on other sites More sharing options...

What's less clear is whether or not they can reliably perform 150m hops with their current methods and technology, and given how many test articles blew up due to pad procedure problems, this is an important thing to determine.

RealKerbal3x Posted August 22, 2020 Share Posted August 22, 2020 I can't wait to see SN8 fully assembled, that'll be amazing! And the launch pad is still a launch pad, and not a water tower. Quote Link to comment Share on other sites More sharing options...

As you say its training on launching, you also want more launches to see that they goes smoothly having two rockets gives even better feedback here. As you launch higher with more fuel an launch pad fail will get more destructive. An fully loaded superheavy+starship having an engine shutdown 50 meter up will give an kiloton level explosion.

RealKerbal3x Posted August 23, 2020 Share Posted August 23, 2020 Nothing beats the daily sound of the wind, reverse beepers, people hitting things with hammers and the construction of a giant launch pad! Let's hope we see a SN6 static fire today! Quote Link to comment Share on other sites More sharing options...
