My professor really wants to know if the IRIS transceiver, which flew on MarCo, will be used in LEO. In fact so much that he doesn't accept "no" for an answer. I have searched for an example but found nothing.
This is just what I expected because it is just overkill, to big and too expensive for your average CubeSat mission, even when talking about 3U. And who needs DSN support in LEO?
So I will try it here and ask if anyone knows of any mission which has used, or plans to use an IRIS transceiver in LEO, not just for commissioning but to stay there.
Read further about the IRIS cubesat transponder in this answer, the Iris V2.1 CubeSat Deep Space Transponder datasheet and in the NASA JPL page Iris V2 CubeSat Deep-Space Transponder (IRIS) .
