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.
Okay... if you're asking how to change the default ISS's orbit, you need to fire a thruster or use the scenario editor to change the ISS's semi-major axis.
I am not sure if this is useful or not, but the exact mass of JWST at launch will be 6161.4 kg, with 167.5kg of hydrazine and 132.5kg of dinitrogen tetroxide.
Heh. Summer would be H2 2022. A few years ago, on a different site, I was called a "troll" and "SpaceX fanboy" for suggesting it would delay until mid/late 2022.
Would there be anyway for one to easily create an attachment to the ISS along the ITS that rotates with the solar panels? I was thinking of creating the new Boeing solar panels (essentially, my plan is to just take one of your ISS solar array meshes, recolor them, and shrink them in Blender).
Update live: https://www.orbithangar.com/showAddon.php?id=25df45cf-1507-46d4-b886-d8062866d1a7
Now requires Better ISS, Thorton's ISS, and Don's Cygnus addons. Next update (soon) will be to make sure the 2020 ISS missions are also updated for Better ISS.
Note for DART: Initial launch...
Expecting to release a significant update this weekend. DART doesn't feel complete to me, but I've got the trajectory down I think.
IXPE is a ton of fun to simulate. I used a dummy satellite for a placeholder for the orbit and InterplanetaryMFD to match the orbit. Does the job perfectly.
Still working on this... can't seem to figure out DART's launch trajectory. Any tips? I have it in a 64.7 inclination orbit at SECO, 200x300 km. I know there's a dogleg but I don't know the initial launch inclination to put F9 on to reach OCISLY. Falling behind as SpaceX already has another...
