WISE.. another space telescope... I have found this today... http://wise.ssl.berkeley.edu/documents/WISE_in_a_box_3b.pdf
Let's try to make this...

Updates for OSIRIS-REx and GRAIL... this will show the trajectories with still greater accuracy...

on the image, Osiris-Rex making its way through asteroids like Apollo Pha

Yes, Gironde...

Here the new orbits for the asteroids Bennu and Ryugu... SSC and XYZV-files... ( SSC-file for Ryugu was corrected )... and in the pictures below you can see OSIRIS-REx spacecraft and Bennu with this orbit of asteroid... But! You need to know that still no one know the real diameter of Bennu... and s...

Today (soon) I will prepare the orbit with "timeline" for 101955 Bennu... otherwise OSIRIS-REx will never reach the goal of the mission in the Celestia space... :biggrin: but this what I have currently... "101955 Bennu:Bennu" "Sol" { Class "asteroid" Mesh &quo...

Texture for the 1 stage of Pegasus XL I made by myself.... because original texture with a not correct American flag (it is about stars)... too bad I did not found the picture of the Pegasus logo (usually it is on the fairing), so I used original texture for it, which with some small problem... Part...

Note: 1. As part of the addon, a temporary version of the ssc file, which orientates Pegasus SWR in an upright position. This is not true, tk. start occurs from the belly of the aircraft L-1011 Stargazer. 2. In the Kepler parameters panel, the altitude is ~ 800 km. At this altitude of 61 km the thi...

The Pegasus is an air-launched rocket developed by Orbital Sciences Corporation (now part of Northrop Grumman Innovation System after Northrop Grumman acquired Orbital ATK). Capable of carrying small payloads of up to 443 kilograms (977 lb) into low Earth orbit, Pegasus first flew in 1990 and remain...

With this SSC-file... IRIS(sat) will oriented well... but I made rotation with period ( 0.1)... If you not want rotation around Z-axis... you can use Period zero....(0.0) "IRIS(sat):Interface Region Imaging Spectrograph" "Sol/Earth" { Class "spacecraft" Mesh "iris....

IRIS (sat) is better aligned in the direction of the Sun with: Orientation [120 1 0 0] but not quite. Maybe the original model is misaligned with respect to the z axis. With the .cmod file, we can no longer intervene with Blender. In the picture of wikipedia, the telescope is on the z axis. Is it p...

Next model... is an air-launched rocket PEGASUS-XL... I guess it will be ready tomorrow...

I think that in Celestia, you have to call it IRIS (sat) so as not to confuse it with Iris: 7 Iris: 1847-7 in the search area.

yes, Gironde... you are right..

The Interface Region Imaging Spectrograph (IRIS), also called Explorer 94, is a NASA solar observation satellite. The mission was funded through the Small Explorer program to investigate the physical conditions of the solar limb, particularly the chromosphere of the Sun. The spacecraft consists of a...

Gironde, Croc... Thank you very much!

GRAIL with modified orbit... added still 2 xyzv-files... "GRAIL-A(Ebb)" "Sol/Earth/Moon" { Class "spacecraft" Mesh "grail-a.cmod" Radius 0.0015 Timeline [ { Beginning "2011 09 10 13:10" Ending 2455928.5 # 2012 Jan 02 00:00 SampledTrajectory { Source ...

Just prepared SSC-file for GRAIL... there I used timeline which include Sampled Orbits in the start and the end of mission... and also Ecliptical Orbits... now I testing it... Central body for all of these orbits is Moon... No problem, Toutatis, and bravo for your excellent modeling work ! Thanks Gi...

Okay Gironde... You can stay with your orbit... but I will stay with my opinion...

Gironde... You need to watch Cassini spacecraft trajectory in Celestia... or MESSENGER... learn it better...

Watch Gironde... but your orbit can show only VERY SMALL part of GRAIL mission...

It is truly the orbit of the satellite around the Moon which is displayed and not the curve drawn in relation to its absolute spatial position unrelated to the Moon.

that is funny... the orbit of GRAIL was changed several times during mission....
