Autonomous Lunar Solar Array (ALSA) 2018: Big Idea Challenge Interns

NASA has aimed its sights towards sending humans back to the moon to develop and test technologies needed for future deep space exploration. Permanent power generation structures will play a key role in establishing habitat and in-situ resource utilization (ISRU) structures. Our group, part of the NASA Big Idea Challenge, came up with a concept for a solar array large enough to power a habitat, ISRU activities, and rover exploration in permanently shadowed lunar craters at the lunar poles.

Hall Propulsion Technology Development, NASA Glenn Research Center: 50 kW Thruster Technology EXPRESS Ground/Space Correlation

It is the goal of this activity to develop 50 kW class Hall thruster technology in support of cost and time critical mission applications such as orbit insertion. NASA Marshall Space Flight Center is tasked to develop technologies that enable cost and travel time reduction of interorbital transportation. Therefore, a key challenge is development of moderate specific impulse (2000-3000 s), high thrust-to-power electric propulsion. NASA Glenn Research Center is responsible for development of a Hall propulsion system to meet these needs. First-phase, sub-scale Hall engine development completed. A 10 kW engine designed, fabricated, and tested. Performance demonstrated >2400 s, >500 mN thrust over 1000 hours of operation documented.
