11/8/2023 0 Comments Mars lunar landingToday you’ll make a lander-a spacecraft that can land safely when you drop it on the floor. Once they find one, they need to design and build a spacecraft that can land there without injuring astronauts or damaging the spacecraft. Tell students why it's important to have a spacecraft that can land gently when getting astronauts to and from the Moon or Mars: NASA is looking for safe landing sites on the moon. Future missions to Mars will also need to safely land astronauts on the surface. Spacecraft on their way to Mars may be traveling as fast as 13,000 miles per hour (21,000 km per hour) when they reach the Red Planet and need to slow down to land safely on the surface. NASA plans to continue sending missions to the Moon about once a year after that while also using SLS to launch robotic scientific missions to places like the Moon, Mars, Saturn, and Jupiter. SLS will be used in the Artemis program for a series of uncrewed and crewed missions, eventually carrying astronauts to the Moon during the Artemis III mission. A foundational piece of the program is NASA’s Space Launch System, or SLS, a rocket that will allow for human exploration beyond Earth’s orbit. NASA’s Artemis program will return humans to the Moon by sending the first woman and the first person of color to the lunar surface. And if there are astronauts onboard, the lander also needs to keep them safe. Since a spacecraft can go as fast as 18,000 miles per hour (29,000 km per hour) on its way to the Moon, it needs to slow down in order to land gently.

In this composite image from 1969, astronaut Buzz Aldrin can be seen coming down a ladder from the mission's command module (or lander).
