- Reaction score
If it's on an escape trajectory, NORAD TLEs and sites that track them such as n2yo are not going to be relevant for long, since these are meant for earth orbit.
Hi Marg, I'll have another go at improving the particle streams when I get some time, but my PC doesn't react well to lots of particles, so I tend to keep it minimal.I would like to note, that deflection smokes could be much longer sustained. In my multistage2015 experiments I made particles with long life times (16 secs), and FPS did not suffer on my moderate PC
Couldn't find any orbital elements on that n2yo page - did anybody grab them?
Booster separation of the real FH was at 2:34 into the launch at 60km altitude. Even with less than minimal reserve fuel, the FH in Orbiter seperates the boosters 14 seconds before at 50km.
I am not sure why that is. It seems the throttle of the side-boosters was varied quite a bit during the launch. I am not sure if that explains it, because I would expect an altitude above 60km if that's the explanation. I tried correcting for this by using negative crossfeed, but that's not an option.
Any ideas on this?
This image from the original webcast is useful. 30 sec post core sep. and the boostback burn is well under way, about half-way to the ASDS (so it is fairly far downrange for Spacex) Plenty to considerAnd why put the ASDS where they did? Why not further down-range, so you don't need to kill ALL forward vel.?
I don't think you're doing anything wrong.Just having one slight problem and I'm not sure what I am doing wrong. When both boosters and the core land they sink a little into the ground/barge and lose their shadows.
I don't think you're doing anything wrong.
The "sinking" problem I think is largely due to how the vessel's "Touchdown Points" are defined, specifically the stiffness and damping parameters. At least the boosters don't bounce around too much - best I could do.
The landing pads/ASDS are defined as vessels - Orbiter doesn't show shadows "on" them.
Running the scenarios I have no sound (except MCC staging callouts)...:shrug:
But there is a vessel with "Fairing Recovery" tag, so I think it must be part of the plan.But it's true on the drawing there are no parachutes with fairings ...
