ORBITER-FORUM will be temporarily closed at 2026-07-23 18:00 UTC while we complete some OF maintenance tasks. The amount of downtime is expected to take up to one hour, but probably less.
Here's the MS2015 config that I'm looking at. These are the lines for the ICPS and Orion, as well as some cube sats.
[STAGE_2]
MeshName=SLS_2016\SLS_ICPS4
Diameter=5.000
Height=13.700
EmptyMass=3488.125
FuelMass=27220.000
Thrust=111010.000
BurnTime=1125.000
ignite_delay=10.000...
Could someone help me make sense of the Orion/ICPS delta-v? The numbers for empty mass, fuel mass, Orion mass, et cetera all check out in the addon. But, try as I might, cannot get the Orion capsule on a trans-lunar trajectory. I seem to get an apogee of ~20,000km before fuel exhaustion. Are the...
We must've been close by then. I was also on a boat in the Banana River for this launch.
Still one of my favorites to see in person, although the first Falcon Heavy launch eclipses it just for pure spectacle.
Tons of juicy details for you, Brian.
First: Probable Starship orbital attempt TLEs.
Second: Elon has dropped specs on booster thrust and Raptor performance:
It's my suspicion that the Falcon 9 does a "dog-leg" maneuver during crew launches. The droneship locations for Falcon 9's first stage doesn't make any sense otherwise.
I'd say the new iROSA solar panels would be very good to work on next. Two are already up and installed on the ISS and they're a pretty significant visual change to the ISS as a whole.
Not a bug, it's stopping to play audio from the Apollo 11 missions at certain points. Delete the audio files from Apollo 11 if you don't feel it necessary.
Honestly, ISS A-to-Z also CTDs for me and I'm not sure why. I think it's something to do with SC3 being used so extensively and not being compatible with Orbiter 2016.
Updated for CRS-22! Nice to have a non-sooty Falcon 9 again with a Dragon, always looks slick.
Note that this mission has a rare boostback burn back to OCISLY. We haven't seen a Falcon 9 landing like that in a while.
No iROSA in this scenario, but I'm sure Don is working on that. Requires the...
