Map the hydrogen content of the entire South Pole of the moon, including within permanently shadowed regions at high resolution.
Map the hydrogen content of the entire South Pole of the moon, including within permanently shadowed regions at high resolution. Measure the bulk hydrogen content, up to a meter beneath the lunar surface, while the instruments on both Lunar IceCube and FLASHLIGHT will tell us about the very top few microns. Create the high-resolution maps of regional near-surface (top-meter) water-ice distribution across the entire South Pole of the moon.
The mission team also made several attempts to image the Earth and Moon; however, these images resulted in saturation of the star tracker. In the coming weeks, additional imaging opportunities of the Earth and Moon will be evaluated to help further demonstrate these novel autonavigation capabilities.
While a recent telemetry downlink showed an unexpected spacecraft reset, a Deep Space Network (DSN) pass has since indicated that, with the exception of the likely stuck propulsion system valve, the spacecraft is healthy with all subsystems nominal and operating as expected.
The problem instead was with the cubesat’s propulsion system, an electric thruster called BIT-3 from Busek that uses solid iodine as propellant. The thruster did not operate as expected in the days after launch, causing the spacecraft to miss its primary opportunity to maneuver into orbit around the moon.
