“What we are embarking upon is extremely challenging,” Isaacman said. “We know so little from what is a combined 80 hours of lunar astronaut EVA time across the Apollo missions, and that was more than a half century ago.”
To that end, one of the central elements of the early Moon Base program is the development of the MoonFall program, which will entail three or four drones each about 1 meter tall, with a mass of 225 kg, including propellant. NASA’s Jet Propulsion Laboratory is leading development of the MoonFall drones, and these will be delivered to the lunar surface by Firefly Aerospace, Garcia-Galan said.
The goal is to get these spacecraft to the Moon before the Artemis IV lunar landing mission, scheduled for no earlier than 2028, to provide high-resolution imagery of the lunar surface. For most of the Moon, the current imagery resolution is 1 meter, and NASA wants to improve it to 1 cm, Garcia-Galan said.
Establishing a perimeter
These drones will perform a number of functions, including scouting for water ice in permanently shadowed regions, identifying areas of scientific interest, and providing detailed information about landing sites, including soil mechanics, lighting conditions, and the terrain. At the end of their flying lifetime, the drones would then be used to set a boundary for the Moon Base.
“We’re hoping to … establish a Moon Base perimeter with four or three lunar drones,” Garcia-Galan said. “We’re going to be able to basically put them at the corners of the areas where we think we have either key scientific objectives, or we want to build up the Moon Base.” In these positions, he added, the retired drones could also provide a beacon with retro-reflectors, or even perhaps serve as the first lunar cell towers.
