The ASU-led team that built NASA's Lunar Polar Hydrogen Mapper, or "LunaH-Map" for short, has safely delivered their spacecraft to NASA's Kennedy Space Center in Florida in preparation for a launch expected later this year on NASA's Space Launch System (SLS) Artemis I rocket.

LunaH-Map is a fully functional interplanetary spacecraft about the size of a large cereal box and weighing about 30 pounds. It is the first mission to be led, designed, assembled, integrated, tested and delivered from the ASU Tempe campus. Its destination is in orbit around the moon, from which it will map water-ice in permanently shadowed regions of the lunar south pole.

Vanderbilt astrophysicist Karan Jani has led a series of studies that make the first case for a gravitational wave infrastructure on the surface of the moon. The experiment, dubbed Gravitational-Wave Lunar Observatory for Cosmology, uses the moon's environment and geocentric orbit to analyze mergers of black holes, neuron stars and dark matter candidates within almost 70 percent of the entire observable volume of the universe, he said.

"By tapping into the natural conditions on the moon, we showed that one of the most challenging spectrum of gravitational waves can be measured better from the lunar surface, which so far seems impossible from Earth or space," Jani said.

"The moon offers an ideal backdrop for the ultimate gravitational wave observatory, since it lacks an atmosphere and noticeable seismic noise, which we must mitigate at great cost for laser interferometers on Earth," said Avi Loeb, professor of science at Harvard University and bestselling author of books about black holes, the first stars, the search for extraterrestrial life and the future of the universe.
