It landed-in one piece! Whew!

7 minutes of terror–like Schrodinger’s cat, no one knew if the lander was dead or alive.  What makes Perseverence of particular interest to us is that it’s primary job is to look for signs of life. It will also conduct experiments to make oxygen from the carbon dioxide. This will be critical for a human landing on the planet.

Mars is a really busy place right now. There are 18 artificial satellites in orbit, 8 of them active.  https://en.wikipedia.org/wiki/List_of_Mars_orbiters
