Geotail was a NASA/ISAS satellite that measured the Earth's magnetosphere. It was launched in 1992, and its operations continued until the last of its two onboard data recorders failed in 2022, thus subsequently ending the mission. It remains inactive in a highly eccentric orbit to this day

The Orbiting Carbon Observatory-2 (OCO-2) is a NASA environmental satellite dedicated in studying carbon dioxide concentrations and distribution in the Earth's atmosphere. It was launched in July 2014, its findings are being complemented by the OCO-3 instrument currently mounted on the International Space Station. It is still active as of 2024.

This serves as an update/replacement to the add-on of the same name by gironde. CMOD model is derived from NASA's Eyes of the Solar System website

Post #186by SpaceExplorer » 01.10.2024, 00:36

The Solar Dynamics Observatory (SDO) is a NASA solar observatory, launched in 2010-Feb-11, and operated in an inclined geosynchronous orbit. It continuously observes the Sun at different wavelengths. Remains operational in 2024.

This is an update to the old addon made by BrianJ on Motherlode:
- More accurate and recent orbital parameters. Epoch 2460584.5 (2024-Oct-01);
- Model converted to CMOD by DaveBowman2001.

Cluster II are a series of four European-built satellites that studied the Earth's magnetosphere and its long-term interactions with the solar wind. It was launched in pairs from two Soyuz-U/Fregat rockets in 2000, and is now currently being decommissioned between 2024 and 2026

Infrared Space Observatory (2024)

Post #189by DaveBowman2001 » 07.10.2024, 08:00

cover_image.jpg
The Infrared Space Observatory (ISO) was a European space telescope designed to observe the universe in infrared light. Launched in 1995, it serves as a follow-up mission to NASA's IRAS satellite, and is placed in a much higher Earth orbit. However, operations were terminated in May 1998 when its helium coolant supply was depleted, making it unable to perform further observations. It is expected to reenter Earth's atmosphere within 20-30 years after shutdown

This add-on serves as an update/replacement to the add-on originally made by Jack Higgins.

Uploaded an update to John van Vliet's Double Asteroid Redirection Test (DART) on its original thread here. Spacecraft now completely stops moving on the moment of impact with Dimorphos instead of phasing through

There is a way actually. Upon setting up a Timeline block, get the Planetographic coordinates of your spacecraft's center on the moment of impact....then fine-tune the time in (TDB) when it reaches that point. If it is an intentional crash, make its Ending very short (I set mine to 0.001 seconds).....this way, it stops moving even if there's still state vectors defined in either spice or xyzv after the supposed impact.

I first tested this with FarGetaNik's Deep Impact, then later applied it with the Chandrayaan's Vikram landers (you could check the rewrite I did with DART's ssc file)....they were based on how Jestr managed to land Huygens on Titan on his 2017 version of Cassini

cover_image.jpg
NASA's Advanced Composite Solar Sail System (ACS3) is a 12U-cubesat mission as part of the ELaNa program. Launched in April 2024, it is designed to test composite materials needed in building solar sail propulsion, which could help enable future deep space missions without the need of additional conventional rocket propellant.

Van Allen Probes (2024)

cover_image.jpg
The Van Allen Probes, also known as the Radiation Belt Storm Probes (RBSP), were two NASA robotic spacecraft designed to study the Earth's Van Allen radiation belts. Launched in 2012, they were placed in a highly elliptical orbit and operated for seven years until they were both decommissioned in 2019. They were expected to be naturally deorbited by 2034

Thinking of releasing a new updated version of the Space Shuttle add-on, cleaning up the relatively messy file structure it currently has since it was last updated in May 2022 before adding more Shuttle-related missions to it

Mars Climate Orbiter

Post #198by DaveBowman2001 » 22.10.2024, 01:20

cover_image.jpg
The Mars Climate Orbiter (MCO) was a NASA mission designed to study the Martian climate, atmosphere and surface changes in orbit. It was part of the Mars Surveyor '98 mission alongside Mars Polar Lander, however it was unintentionally destroyed about 57 km above the Martian atmosphere due to its onboard computer being unable to convert metric and imperial units during orbital insertion

A huge thank you to pedro_jg for reconstructing its trajectory data from NASA Archives, with the state vectors during atmospheric entry being supplemented using Orbiter2016. Credits to the original model's author, emin31284, from SketchFab

The Magnetospheric Multiscale Mission (MMS) is a group of four NASA satellites dedicated in studying the Earth's magnetosphere. They were all launched by a single Atlas V rocket in March 2015, complementing the findings of the earlier Cluster-II mission. All satellites have enough fuel to remain operational until at least 2040
