Robot lander tests

Roamy here. NASA is working with Johns Hopkins Applied Physics Laboratory to develop robotic landers for either the Moon or a near-Earth asteroid. They posted a neat test video on Facebook yesterday.


The lander is 4 feet tall and 8 feet in diameter and weighs about 700 pounds when fueled. If it looks like a smaller version of the “Flying Bedstead”, a.k.a. Lunar Landing Research Vehicle/Lunar Landing Training Vehicle, you’re right. The physics of landing without an atmosphere is the same. The LLRV used a jet engine for its main thrust, and hydrogen peroxide lift rockets for secondary propulsion. The Robotic Lunar Lander uses just the hydrogen peroxide engines but more of them.
