Loved the three minute video/audio clip => See Perseverance's latest rover tracks & Mars' 'litter' pics (with Sol 16 audio), with the rover's titanium wheels squeaking, crunching, screeching as they roll over the Martian regolith. Not at all like the sound rubber tires make anywhere on earth.

titanium wheels squeaking,

Too many PHD engineers and scientists working at NASA. They should have hired a neighborhood mechanic to grease the wheel bearings....

It’s good to see NASA take some time out from their main objective: Muslim Outreach

All legs have deployed. The only thing left is to drop it 5” to the surface and back away to observation point.

Amazing a helicopter can be designed that will operate in an atmosphere less than 1% of Earth normal pressure.

Earth Sea level: 14.69 PSI
Top of Mt Everest: 4.89 PSI
Mars: 0.095 PSI

How far are they going to get without an oil pan.

Interesting audio. At some points, you hear a typical metallic “ping” of a metal object striking a surface and “ringing”. I wonder how sound waves are influenced by the very low pressure of the atmosphere?

It's the second thing Perseverance dropped in recent weeks, after an unneeded belly pan relating to its sampling system.

Life imitates art. There is a GROANER Sci-Fi horror pic titled "The Creeping Terror" - (some college students under a carpet monster goes around devouring various humans. Incredibly bad acting as well.)

What I found interesting was that at the end, it was discovered that the "creature" was sent by an alien race to see what was on Earth, sampling the environment and sending back the chemical makeup - YEARS ahead of our Mars explorer. :-)

Just curious, IIRC, moon rocks are the most expensive item, by weight, on earth. So if we get rocks from Mars I’m guessing moon rocks look cheap huh?
