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.
Requesting for a modified version of the Cargo Dragon 2 spacecraft that will eventually send the ISS to its final resting place at the bottom of the Pacific Ocean by January 2031 at the latest
I'd like to request for an add-on of the Jupiter Icy Moons Explorer (JUICE), which was launched from the penultimate Ariane 5 flight in April 2023, now on its way to Jupiter alongside Europa Clipper, both expected to arrive by 2031 and 2030 respectively.
Since we have Peregrine and Nova-C available to fly on Orbiter, I'd like to request an add-on for Firefly's Blue Ghost lander, where (on its first mission) it achieved the first fully successful American lunar landing since Apollo 17 in 1972.
NASA's still-unnamed Uranus Orbiter and Probe (UOP) concept was selected as the highest priority for the next Flagship-class mission according to the 2023-2032 Planetary Decadal Survey. As of 2023, it is planned to be launched from a Falcon Heavy around 2031 at the earliest, and will arrive at...
With Japan just became the fifth country to successfully land on the Moon (albeit briefly) anyone interested in making add-ons for them?
Hakuto-R (Mission 1)
SLIM
I would like to request for an addon or a series of addons depicting the cancelled Mariner Mark II probes of the 1980s, which basically share the same design in hopes to minimize cost. Only Cassini was launched in this program. All of them are planned to be launched on a Titan IV-B/Centaur...
This thread will host the development of the Soviet Venera program for Orbiter2016 as requested by 4th rock and N_Molson here. I'm thinking that the Soviet Mars program be also included here since it shares similarities in technology with Venera.
Lately I'm very thrilled at the Mariner series of space probes of the 1960s, and the relative difficulty of flying them in Orbiter. And since Mariner 4 and Mariner 6 became available for download again on OHM, I found out that only Mariner 5 hasn't been made into an addon yet. So I decided to...
H-IIB (H2B) was an expendable space launch system jointly developed by the Japanese government's space agency JAXA and Mitsubishi Heavy Industries. It was used to launch solely the H-II Transfer Vehicle (HTV, or Kōnotori) cargo spacecraft to the International Space Station. It flew nine times...
Soyuz is a series of spacecraft designed for the Soviet space program by the Korolev Design Bureau (now RKK Energia) in the 1960s that remains in service today, having made more than 191 flights. The Soyuz succeeded the Voskhod spacecraft and was originally built as part of the Soviet crewed...
Atlas V is an expendable launch system and the fifth major version in the Atlas rocket family. It was originally designed by Lockheed Martin, now being operated by United Launch Alliance (ULA), a joint venture between Lockheed and Boeing.
This addon includes real-life launch commentaries of...
Vulcan Centaur is a two-stage-to-orbit heavy-lift launch vehicle under development 2014–2021 by United Launch Alliance (ULA), principally funded through the US government's National Security Space Launch (NSSL) competition and launch program, to meet the demands of the United States Space Force...
Antares is an expendable launch system developed by Orbital Sciences Corporation (now part of Northrop Grumman) and the Yuzhnoye Design Bureau to launch the Cygnus spacecraft to the International Space Station as part of NASA's COTS and CRS programs. Able to launch payloads up to 7,500 kg into...
This addon adds real-life launch commentaries to all 135 individual Shuttle missions from 1981-2011. This is a major recompile of my previous releases and updated according to the latest development of gattispilot's Space Transportation System 2016. Most payloads running previously on...
Magellan is an American spacecraft sent to orbit Venus to obtain high-resolution radar maps of the surface from 1990-1994. On this day, the maps obtained is still the most-detailed map of the Venusian surface ever made.
This is an addon many months in the making, and actually finished in May...
This is an addon that includes real-life launch commentaries of individual Falcon 9 and Falcon Heavy launches that will hopefully supplement/enhance the compilation made over the years by Kyle's SpaceX Mission Package (2016-Present).
To prevent myself from overwriting Kyle's addon, there are NO...
The Mars Exploration Rovers (Spirit and Opportunity) have their own Orbiter addons uploaded into the Hangar for some time (Made for 2010, but I think it can also work in 2016 since it is SC3/4 based). The Pathfinder and Sojourner has a beta version loaded somewhere in the Forum too
I've been...
