New Glenn might be the only rocket capable of lifting Orion to LEO

Orion launching on other rockets than SLS now being seriously considered by NASA and Lockheed Martin https://arstechnica.com/space/2025/10/once-unthinkable-nasa-and-lockheed-now-consider-launching-orion-on-other-rockets/

Isn't the LK run on hypergolic fuel?

This NASA document details the proposed specifications for UOP, from its launch mass, instruments, engines, propulsion system, power generator, and even preliminary trajectory: Uranus Orbiter and Probe 2023–2032 Planetary Mission Concept Study (PDF) Assuming a launch date of 20 June 2031 from...

Planning to restart the "Launch Sounds" series later this year

JPL hasn't yet published detailed trajectory plans for the two EscaPADE probes, but it should follow this one (obviously outdated now, but still)

Turns out I have an obsolete Multistage2015.dll installed on mine. Everything works now again. Thanks!

I've encountered a problem running the Soyuz missions on Orbiter 2016. Not sure why they are in weird positions lately, I've never encountered them doing this before: Every Soyuz scenario has the entire launch complex and rocket buried deep within the Earth upon starting simulation

Everything looks perfect! Even the suntracking is fully functional now! Thanks. I guess only one panel on the +X side seems to deploy too early atm, causing it to phase through the other panels of the array

Don't ever get that madman at Harvard coverage. He's nothing but a looney and a disgrace to the astronomy community

I confirm the animations are fixed. All the instruments no longer phase through the main body. The solar arrays need a little work but it is better than before :hailprobe: The tracking does not yet work properly however....upon solar panel deployment, it is totally non-responsive

Alright, here's the new launch configuration and scenario. Fortunately, the original guidance file almost closely matched that of JUICE's actual launch profile, so I just simply removed every parameter that shuts off the upper stage's main engine. Also added a WAV file that plays the mission's...

Just as I suspected. According to its Launch Press Kit (2023), JUICE was indeed launched directly into an interplanetary escape trajectory, as it was jettisoned from the Ariane 5 about T+26 minutes after liftoff (highlighted): I'd like to attempt a modification of its guidance file that will...

If I remember correctly, a few years ago, JPL HORIZONS had trajectory data available up to Ganymede orbit insertion. Unfortunately, when I revisited it again, the data just abruptly ends on Jupiter Arrival Day (July 21, 2031). I think that was removed sometime during its launch. Despite this...
