This past week, NASA declared the end of the Mars Opportunity Rover mission. For a little robot rover that was supposed to last 90 days on the surface of Mars, this little robot blew away all expectations by lasting 15 YEARS! It showed Mars had running water on its surface at some point in its history and made many other scientific discoveries.
Opportunity…you will be missed.
Hopefully, someday, earthlings will be able to bring you home so you can be displayed in the Smithsonian Air and Space Museum (wouldn’t that be great!).
