What gravitational challenge do astronauts face upon arriving at the Martian surface?
Answer
38 percent of Earths gravity
The Martian surface possesses a gravitational field that is only 38 percent of that found on Earth. Astronauts who have already experienced bone density loss and muscle atrophy due to the extended period of microgravity during the long transit must then adapt to operating in this significantly weaker gravitational field, which complicates long-term health and daily physical functionality.
