Mars: Top Ten Fun Facts


One of the first images taken by Perseverance on Mars!

Do you remember when I had the good fortune of chaperoning Team Mercury to the Kennedy Space Center? My daughter, along with her team of high school Space Exploration students and their teacher John Yi, took a trip to the KSC when they won NASA’s App Development Challenge. We watched the launch of a rocket, NASA’s Orion Ascent Abort-2, toured the building where rockets are built, the Vehicle Assembly Building, built our own rockets, stood under the Space Shuttle Atlantis, and learned about NASA’s work to get Perseverance to Mars through lectures and participation in the Mars Experience.

On February, 18, 2021, Perseverance landed on Jezero Crater on Mars, and the excitement of the engineers at NASA’s Jet Propulsion Lab was palpable. Perseverance, which launched from Earth on July 30, 2020, will stay on Mars at lease one Mars year (657 Earth days) with a goal of seeking “signs of ancient life and collect samples of rock and regolith (broken rock and soil) for possible return to Earth.” Hon, did you watch the landing?
