3. You can watch the surface of Mars live as seen from orbit by the Mars Odyssey THEMIS mission here: https://themis.asu.edu/livefrommars (I say live, they video is usually about two weeks old).
5. The Viking 1 lander had a mission projected lifetime of 90 days on the surface of Mars. It transmitted data to Earth for over 6 years.The Curiosity rover had a mission projected lifetime on the surface of Mars of about two Earth years. Nearly nine years after landing it’s still sending us data.

9. Approximately 50% of all space missions to Mars have failed before returning any data to us. Effectively, every Mars mission needs double the budget so we can send it twice!
