I'm trying to locate all the OSIRIS-REx engines.
Here: http://spaceflight101.com/osiris-rex/osiris-rex-spacecraft-overview/ (Propulsion System) I read that there are: 4 x 275 N, 6 x 22 N, 16 x 4.5 N and 2 x 80 mN.
My biggest doubt is about the four 275 N engines.
I'm using the 3D models found here: https://nasa3d.arc.nasa.gov/detail/osirisrex-2013-comp, https://solarsystem.nasa.gov/resources/2360/osiris-rex-3d-model/ and https://sketchfab.com/3d-models/osiris-rex-4502d7705147439eab474902fa283c89.
All the models show the 6-engine group, but I don't see the 4 main engines.
Where are the 4 main engines?
Re-asked question: Where are the 6 22-N OSIRIS-REx engines?
Here https://mk0spaceflightnoa02a.kinstacdn.com/wp-content/uploads/2016/08/10.jpg we see 4 main engines. I thought that the spaceflight101.com image was an outdated preliminary image, but it seems that that image is correct and that the 3D models are wrong.
Then I need to change the question: where are the 6 22-N engines?
