And audio as well!
How are they getting audio without an atmosphere?
There is a thin atmosphere on Mars and sound does exist. It's also how this lander was able to land.

#152Any JPL/NASA HN users that could comment? That would be beyond awesome! Great job, mission!
JPL Engineer here, any questions I could convey to the slack I'll be glad to feed back to HN

Worth noting that these first pictures are sent in the first seconds after touchdown, you can even still see the dust in the air from the landing (even if it was craned down to reduce dust). It also explains the very low resolution in general, they want to get confirmation ASAP, no time for high quality high resolution images.
would dust stay in the air longer or shorter than on Earth? also is it technically correct to call the Martian atmosphere "air"?
Dust falls much, much faster on Mars. The density of Mars's surface atmosphere is ~160x lower than on Earth.

#154im really sad to say that NASAs website is an absolute dumpster fire... does anyone know of a simple repository of all the images and videos captured by each mission? i just want to flip through the pictures perseverance has taken so far without sifting through cancerous news sites.
edit: the closest thing ive found is data.nasa.gov. how hard is it to just generate a fucking simple html website with chronologically ordered images? this is bullshit
edit: ok, here is almost exactly what i wanted: https://mars.nasa.gov/mars2020/multimedia/raw-images/ the internet really sucks compared to what it might be... go to nasa.gov and click percy mission from the drop down and it takes you to a part of nasa.gov thats filled with eye-cancer tiles and javascript with sensor imaging mixed in with PR images and promotional material. but they tuck the (sort of) clean, organized data into some other website basically? maybe its a small gripe but this way of doing it is disorganized and infuriating.
edit: wow, this website is fucking amazing! you can see the real-time position of all nasa mars vehicles 3D google earth style: https://mars.nasa.gov/explore/mars-now/ anyone who has not looked around in mars.nasa.gov should bookmark that right away

Greetings from Jezero Crater! Really doesn't look alien. RLike the high mesa of New Mexico sans flora ;)

Perseverance is one of the largest objects that NASA landed (along with the Apollo lander), and it's about the size of an SUV. SpaceX is trying to land things the size of buildings. Let's just say it's a very different problem.
.
Actually, all the Starship flights are fully automated, possibly except a very nervous person somewhere with the self-destruct button and binoculars.
If you though there is someone in Boca Chica flying Starship remotely with joystick and steady hand, I'm afraid I need to disappoint you.

NASA actually made a pretty informative page about it[1], with some simulation of sound on Mars, compared to Earth. Hopefully we won't need the simulation much longer!

How could you know? SpaceX never landed or sent a craft on a foreign body.
SpaceX hasn't been around as long as NASA. Also, remind me, did NASA develop reusable rockets?
Well, nssa worked on Delta Clipper and DC-X. Also Venture Star. And the integrated powered demonstrator/FastTrack & pointless injectors that formed the basis of the Merlin engine IIRC.
