From what I've read, this is a pretty common sentiment and one NASA (and fans) tries to correct often. I also feel like this launch has many more photos of Perseverance with people in the image for scale than prior launches. The disconnect from the size is likely just a holdover from when the rovers were small (clockwise from bottom: Sojourner, Spirit/Opportunity, Curiosity/Perseverance).
Is the raw footage online somewhere? Edit: it looks like the individual frames from the videos (along with other images) are here. I guess I'm looking for something slightly less raw than that.

This is amazing. I believe the first actual real time video recording from beyond the moon? This probably took most of their bandwidth since landing :)

I watched the landing live, I remember holding my breath during the last few seconds awaiting touchdown confirmation and feeling great relief and excitement just as they did when the room erupted in celebration. The same frisson occurred watching this video to see it happen live. Just extraordinary.
I do wonder how long it took to get all that video back...
30 gigabytes... Some of my dayjob involves downlinking megabytes at a time from spacecraft in low-Earth orbit, and that's hard enough. I'm in awe of what it must take to downlink gigabytes from Mars.

How do they do that? I know it's Rover -> martian satellite (Mars Recon Orbiter?), but what about after that? Is there enough speed that they can transmit that kind of data all to a single dish on earth, or do they have divvy it up to various dishes as the planet rotates? Or maybe they transmit to a satellite network that compiles and sends to a single point on earth?
I've got so many questions and so little understanding of how this works!
I don't know many details about it either, but I know it involves the awesomely named Deep Space Network. It definitely gets split up among multiple groundstations as the Earth rotates. There's...

It definitely gets split up among multiple groundstations as the Earth rotates. There's probably a ton of complexity around scheduling antennas to point at different targets (since the DSN supports more than just the Mars mission) and probably scheduling / multiplexing that downlink from Mars (since it's useful to receive real-time telemetry from the rover at the same time as you're downloading multi-GB video & picture data in the background).
I'm so giddy! Watching this is just incredible. It's exciting and beautiful! I'm just awed about all of it, and the quality is great. It'll be super awesome to see more on Mars in even greater...

When I saw the pattern on the parachute as I was watching I thought there must be some meaning behind the pattern they chose. The presenter also heavily hints at a hidden message.
Woah, it's way bigger than I expected. For some reason I'd gotten in my head that Mars rovers were around the size of a bike or large dog.

The live stream of the press event is also well worth watching as they analyse some of the things us amateurs will have missed - starting at around the 16 minutes mark.

Sure enough those parachute patterns are encoded
