Probably around 20-30 minutes after it's landed. Perseverance needs to lock onto sattelites that are part of the Deep Space Network for the bandwidth required to send media. It also takes 22 minutes to send a command and get a response back.
- comfydragon 6y agoWe actually got a picture like 3 minutes after landing. (Okay, a picture from shortly after landing.)

- shadowgovt 6y agoIf I understood the livestream correctly, it's because they were able to (maintain|quickly establish) lock to the MRO after touch-down and zip a couple of images up through the "bent-pipe" UHF-to-high-power relay into the Deep Space Network.
- GeorgeTirebiter 6y agoIt would seem they had MRO in position to snap a few photos of the landing / descent as well as do the relay.
- ceejayoz 6y agoIt was already communicating with DSN the whole way down, via one of the orbiters, and "send a pic" was apparently a pre-programmed command not requiring Earth initiation.
