Here at Marymount we love interacting with schools around the globe, and what better way to do that than with an experiment. Ms. De Paoli’s grade 10 class is doing an experiment with Highland High School in Salt Lake City, Utah where we exchange our creations and test them out. The creation: a rover and lander that will successfully protect and egg while performing tasks. This teaches us about payloads and methods NASA has used to protect payloads in the past.
The Lunar Roving Vehicle created by NASA for the Apollo missions inspired our rover. Also known as “the moon buggy”, it was a battery-powered rover used for Apollo 15, 16, and 17 missions during 1971 and 1972. The LRV was sent to the Moon on the Apollo Lunar Module (LM) and was designed to sustain low gravity so it could traverse the lunar surface easily. It was sent so that we could learn more about the moon and extend the area’s explored by humans.
A lander is a spacecraft, which descends onto an astronomical body. Landers have touched down on many celestial bodies such as the Moon, Venus, Mars, and many comets and asteroids. In 1959, the first successful space lander, the Luna 2, was launched and landed on the Moon.
After creating the lander and rover, we tested it for ourselves. We dropped the lander from a height of 5 meters, and rolled the rover down a slope of 90 degrees. They were both quite successful in keeping the egg intact. Then we sent them to the school in Utah, and they did the same for us.
When their lander and rover arrived, we tested it immediately. Unfortunately, neither was successful in keeping the egg intact while undergoing the tests. Overall, the interaction with schools in America and learning more about space technology was a great experience, and we thank Ms. De Paoli for the idea.
