Lisa Watson-Morgan, center left, program manager of NASA’s Human Landing System Program at NASA’s Marshall Space Flight Center in Huntsville, Alabama, shows NASA Administrator Jim Bridenstine equipment used to test seismic sensors on a lunar lander platform on a simulated lunar surface at the center Aug. 16, 2019. Bridenstine was joined by Representatives Mo Brooks and Robert Aderholt of Alabama and Representative Scott DesJarlais of Tennessee. Planetary scientists performed the experiment to learn how these waves travel through simulated regolith, which is material similar to the Moon’s surface. The experiment will help guide instrument deployment scenarios for NASA’s Commercial Lunar Payload Service (CLPS) Program, delivering small science and technology payloads for Artemis. That same day, Bridenstine announced Marshall will lead the agency’s Human Landing System Program. (NASA/Fred Deaton) For more information: https://www.nasa.gov/artemis-1
