It's from a hazard camera, which is not used for main photography. Better images will come soon.


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.


The low resolution and fuzz is also because they still have the lens caps on - they are of course transparent lens caps in case the explosive bolts that will release them fail. Redundancy!


This is one of the cooler things that I learned today. Could they go even further: make the caps themselves lenses+filters. Take photos. And then blow them off for new photos.


would dust stay in the air longer or shorter than on Earth?

also is it technically correct to call the Martian atmosphere "air"?


Yes, but it's not technically correct to call Martian seismic tremors "earthquakes".

Flash Gordon (1980) Goofs

At the very beginning of the film, Ming and his henchman are discussing "an obscure body in the SK system", which the inhabitants refer to as the planet "Earth", pronounced as if the word is completely foreign to them. However, at that moment, Ming activates a button on his console labeled "Earth Quake".

Star Trek calls them "quakes" I noticed


Dust falls much, much faster on Mars. The density of Mars's surface atmosphere is ~160x lower than on Earth.


Right. One "proof" advanced by Moon landing conspiracy theorists was that dust settled much faster in videos than it should if it were really in Lunar gravity.


Miriam Webster says yes to part two:

> the mixture of invisible odorless tasteless gases (such as nitrogen and oxygen) that surrounds the earth

> also : the equivalent mix of gases on another planet

I would naively guess yes to part one but it's complicated: Mars has less gravity, much less atmospheric pressure, colder temps, and greater gravitational influence from its moons than Earth. Wikipedia says the mechanism of the planet's dust storms isn't well understood.
