I wasn't even aware of this launch until a couple of days ago. From Spaceflight Now: https://fireflyspace.com/blue-ghost/ https://hakuto.r.ispace-inc.com/hakuto-r/eng/about/ Cheers, BrianJ

BrianJ submitted a new addon: Europa Clipper - The Europa Clipper spacecraft. Read more about this addon...

Hi, it was my understanding that the Celestial Body modules in Orbiter use TDB time frame to set their pos/vel, rather than UTC. So any vessels or celestial bodies added to Orbiter using external data (e.g. JPL Horizons data) should use the TDB time as the epoch. But...I just grabbed the...

https://www.bbc.co.uk/news/articles/c3dvxgrmk95o Well, technically yes, eccentricity ref. Earth drops below 1.00 for a few weeks. Attached .zip contains Asteroid 2024PT5, configured as a vessel, and scenario starting 00:00 UTC 26 Sep 2024 State vectors from JPL Horizons. Cheers, BrianJ

Hi, I've come across a strange "anomaly" while trying to launch from the surface of Titan. If anyone has the time, I'd be grateful to get confirmation or whether its just me! It seems the surface of Titan is very "sticky" - I have to apply nearly twice the vessel "weight" in upwards thrust to...

Hi, I thought I'd have a go at the Intuitive Machines "Nova-C" Lunar Lander, launch on Falcon9 now delayed until 12 Jan 2024. https://en.wikipedia.org/wiki/Nova-C I'm including one of its payloads - "EagleCam" cubesat which can image the landing (if you're using latest D3D9 Graphics Client). The...

Hello! I hope this is the right place for ideas about future Orbiter developements. I just wondered if anyone had thought about adding a 3rd aerofoil option for vessels - an aerofoil in the X-Y plane. This would be useful for capsules. It is possible to simulate capsule lift effects with the...

Download: DART The DART and LiciaCube spacecraft, asteroid Didymos and its moonlet Dimorphos. Launch and post-launch scenarios in "DART" folder. Scenarios use custom Solar system config file "Sol_DART.cfg" which includes default Orbiter2016 planets and Didymos/Dimorphos. Installation and...

Danuri (KPLO) S.Korea's pathfinder Lunar orbiter, due to launch this evening (04 August 2022) at 23:08 UTC, on Falcon9. Another mission using a lengthy but fuel-efficient WSB/BLT trajectory to go to the Moon. WSB/BLT can save dV 160m/s at LOI (except not for me in Orbiter, since I use about...

Hi, just a quick heads-up in case it's useful to anyone. I have now received two spam/scam emails to my primary email address (not the one on my account here at OF) from someone calling themselves "Jack Foltz" at "Fixthephoto.com". I guess the idea is for me to respond or click the...

Just a quick note about: Orbiter2016 v.160828 VesselAPI.h "char *GetClassName () const;" This seems to return a character string equivalent to the path to the vessel's .cfg file as used by the vessel entry in the scenario. e.g. For a DeltaGlider this could be "DeltaGlider" or...

I've just been having a look at NASA's "CAPSTONE" mission: Pathfinder for Artemis Going to Lunar NRHO Launched on Rocketlab's "Electron", multiple Apogee raising burns from LEO Ballistic trajectory to Lunar NRHO via Earth-Sun L1 area. Quite a navigation challenge for Orbiter! We already have...
