Storyboard Text
- Astrobiology is a relatively new field of study, where scientists from a variety of disciplines (astronomy, biology, geology, physics, etc.) work together to understand the potential for life to exist beyond Earth. However, the exploration of Mars has been intertwined with NASA’s search for life from the beginning. The twin Viking landers of 1976 were NASA’s first life detection mission, and although the results from the experiments failed to detect life in the Martian regolith, and resulted in a long period with fewer Mars missions, it was not the end of the fascination that the Astrobiology science community had for the red planet.

- The spacecraft, dubbed Hope, launched July 19, 2020, atop a Japanese H-IIA rocket, then spent seven months trekking to the Red Planet. Today (Feb. 9), Hope needed to fire its thrusters for nearly half an hour straight to slow down enough to slip into orbit around the Red Planet, from 75,000 mph to 11,000 mph (121,000 kph to 18,000 kph). Mission personnel on the ground could only watch what happened.
