Europa Clipper (October 2024)

Post #204by DaveBowman2001 » 31.10.2024, 16:53

Untitled2.jpg
Europa Clipper about to fly past Mars, 2025-Mar-01

Update to the Europa Clipper add-on. Updated XYZV trajectory now uses postlaunch state vectors from 14 October 2024 up to early 2026, to provide more accurate flybys of Mars and Earth during its cruise to Jupiter. Had to retain the prelaunch trajectory after the dates mentioned because JPL HORIZONS doesn't yet provide any postlaunch data for the Jupiter phases

NOTE: Must download the Galilean Satellites (1995-2035) addon for more accurate moon flybys and prevent random collisions with them until the Ganymede impact on September 2034

Advanced Composition Explorer (2024)

Post #205by DaveBowman2001 » 01.11.2024, 05:11

cover_image.jpg
The Advanced Composition Explorer (ACE), also known as Explorer 71, is a NASA mission to study matter comprising energetic particles from the solar wind, the interplanetary medium, and other sources. It was launched in August 1997 and reached the Sun-Earth Lagrange-1 point just four months later, where it remains in active operation to this day. It is expected to continue its mission until its propellant is completely exhausted by 2029

This serves as an update/replacement for the 2022 version of this add-on. CMOD model now successfully adapts the textures from NASA's Eyes of the Solar System website. XYZV trajectory data also extended until January 2025 (the current extent of data available from JPL HORIZONS as of this writing)

Explorer 6

Post #206by DaveBowman2001 » 04.11.2024, 08:26

image.png
Explorer 6, also known as S-2, is an early NASA satellite that studied the space environment around Earth. Launched in August 1959, it took the very first photograph of Earth in orbit as an experiment that later led to the development of weather satellites. It remained operational until October 1959 and reentered the atmosphere by July 1961.

Orbital data retrieved from CelesTrak

Meteosat-8 to 11 (2024)

Post #207by DaveBowman2001 » 08.11.2024, 14:26

Untitled.jpg
The Meteosat Second Generation (MSG) were a fleet of four European weather satellites that were launched into geostationary orbit between 2002 and 2015. Each satellite is expected to carry out a 20-year mission monitoring the weather and climate throughout the Afro-Eurasian region until they are replaced with third generation starting with Meteosat-12

All satellites, except Meteosat-8, are still operational as of 2024. Reused the SSC files originally made by gironde for their orbital parameters.

Hera

Post #209by DaveBowman2001 » 10.11.2024, 09:20

Untitled.jpg
Hera during its flyby of Mars and Deimos, 2025-Mar-12

Hera is a European spacecraft aimed to study the Didymos-Dimorphos system in the aftermath of NASA's DART mission in September 2022. Launched in 2024, it will reach the asteroids by December 2026, and hopefully measure the efficiency of the kinetic impact method for planetary defense

XYZV trajectory was retrieved from JPL HORIZONS. Take note that the Didymos phase of the mission is not yet simulated due to lack of publicly released data as of this writing

ADDITIONAL NOTES:
For all those who have asteroid catalogs installed (for example, Minor Planets: 101 to 200), find an entry in their SSC file named 103 Hera and add an (asteroid) tag on its alternate name to prevent any conflicts with this add-on

Example:

Code: Select all

"103 Hera:Hera (asteroid)"

EOLE was a Franco-American weather program (CNES and NASA). The first satellite EOLE 1 was preceded by the launch of a PEOLE test satellite
If EOLE 1 is still present in the CelesTrak catalog, I had to ask for the history of PEOLE.
I offer you here the ssc file for these 2 satellites.
As I did not find a 3D representation, I used a generic one resembling meteosat.cmod. The representation of the solar panels is still missing

Pegasus-1 to 3

Post #212by DaveBowman2001 » 18.11.2024, 16:56

detail_image_1.jpg
A Pegasus satellite, built from a spent Saturn I (S-IV) stage

NASA's Pegasus project are a trio of satellites designed to measure the frequency of micrometeoroid impacts on spacecraft in LEO. Operating between 1965 and 1968, these satellites provided valuable data in the space environment that helped in preparing Project Apollo's crewed missions to the Moon.

Orbital data for all three satellites were retrieved from CelesTrak. All satellites were no longer active and were deorbited since 1979.

UPDATE (241119):
Reposted the Pegasus add-on above as I forgot to enable the Ending dates of the satellites, which caused them to be accidentally viewed on the Present Day. The satellites now disappear from simulation after 1979

The type of 3D model with several cmod to represent a complete satellite
(1 main object class "spacecraft" and 1 second class "diffuse") does not adapt well
to the use of the parameter 'Visible false' or 'Visible true' because to see the object
in its entirety, you have to select the 2 components one after the other and apply
to each of them, the parameter 'Visible true'.

When the object is always visible (by default), the problem does not exist of course.

Is it possible to create models in a single cmod file when the Timeline allows it, that is to say
when the satellite does not transform during its mission? But maybe it is not possible.
