Forgot to post when it happened, but on the 11th and 12th of this month, the MEPAG - Mars Exploration Program Analysis Group, held meetings of which I attended the 2nd day virtually. Amongst other things, there was an update on Mars Sample Return, stating that they had successfully performed test firings of the MAV 1st and 2nd stages, as well as the MAV PDR, both in the week before this meeting. It was also restated that there is a flight demo of the MAV, currently planned for next year out of Wallops. Slides:

EM-1 has become EM-Done

Return Powered Flyby starts in just under 100m, @ 1400 UTC / 0900 EST. RPF burn itself is at 1643 UTC / 1143 EST, with closest approach at 1642 UTC/ 1142 EST

1. All of Gateways' modules are Cygnus based, except for the PPE which is based on one of Maxar's commercial satellite buses. 2. Gateway will require small, but regular correction burns from the PPE due to NRHO not being an entirely stable orbit.

I'm not sure Apollo did anything but direct atmospheric entry, but Orion will be doing a skip-reentry Orion Spacecraft to Test New Entry Technique on Artemis I Mission | NASA

I really hope they share a video of Orion's party mode at some point.

TJ Cooney made a good video on this topic. They've got 2mbps downlink speeds from Orion, at least on average. And yes they are using phased arrays on Orion. They've got 4 on the CM. Here's a cropped image of one of them:

@tater @adsii1970 @darthgently Artemis II will have 4k livestream capability via the Optical Communications System.

thats 100% correct.

I really hope someone's imaging it. It was done during Apollo.
