Living on Mars

For John, BLUF:  Mars is not just like Earth, but without breathable air.  Nothing to see here; just move along.

The Speed of Sound on Mars Is Strangely Different, Scientists Reveal

From Science Alert, by Writer Michelle Starr, 24 March 2022.

Here is the lede plus one:

Scientists have confirmed the speed of sound on Mars, using equipment on the Perseverance rover to study the red planet's atmosphere, which is very different to Earth's.

What they discovered could have some strange consequences for communication between future Martians.

This is very iinteresintg and shows that going to other planets will not be exactly like living on Earth, but with your own oxygen supply.  Not a reason not to go, but rather a challenge to do it sooner and learn and grow.
