NEW ORLEANS — Astrobotic, which is working to squeeze as much life as possible out of its crippled Peregrine lunar lander, says it has obtained data from many of the payloads on the spacecraft.

The company said Jan. 11 that it provided power to, and received data from, nine of the 20 payloads on the lander. They include four NASA science experiments included on the lander as part of Commercial Lunar Payload Services (CLPS) program: the LETS radiation instrument and the NIRVSS, NSS and PITMS spectrometers. The fifth, a laser retroreflector, is passive and does not have power or data requirements.

NASA, in a separate statement, said it was using LETS and NSS to measure the radiation environment in cislunar space. The joint observations “provide complementary insights into the galactic cosmic ray activity and space weather resulting from solar activity.”

“Measurements and operations of the NASA-provided science instruments on board will provide valuable experience, technical knowledge, and scientific data to future CLPS lunar deliveries,” said Joel Kearns, deputy associate administrator for exploration in NASA’s Science Mission Directorate.

A NASA technology demonstration payload, the Navigation Dopplar Lidar, is also powered up and generating data. Other payloads that are active and generating data include the IRIS lunar rover from Carnegie Mellon University, the COLMENA micro-rovers from Mexico’s space agency AEM, the M-42 radiation detector from German aerospace center DLR and Astrobotic’s own Optical Precision Autonomous Landing sensor.

A tenth payload, the Lunar Dream Time Capsule from Japan’s Astroscale and Pocari Sweat, is powered up but does not generate data. The other payloads on Peregrine are passive.

“These payloads have now been able to prove operational capability in space and payload teams are analyzing the impact of this development now,” the company said in a statement. “We are proud of the mission team for achieving this incredible feat under such challenging circumstances.”

Those challenging circumstances involve a propellant leak that started after initialization of the lander’s propulsion system shortly after its Jan. 8 launch on the first United Launch Alliance Vulcan Centaur. That leak caused attitude control problems for the spacecraft and ruled out any chance of attempting a soft landing on the moon in February as originally planned.

In a Jan. 9 update, Astrobotic said its current hypothesis for the propellant link involved a valve in a helium pressurization system that failed to close after an initial test. “This led to a rush of high-pressure helium that spiked the pressure in the oxidizer tank beyond its operating limit and subsequently ruptured the tank,” the company stated. It added that it had no reason to believe the problem was linked to the launch.

The leak will limit the lifetime of the lander; when it runs out of propellant the spacecraft will no longer be able to stabilize itself and point its solar panels at the sun, depriving it of power. The company has been able to stretch out those fuel reserves, and as of late Jan. 10 estimated there were 36 hours’ worth of fuel remaining.

The company said late Jan. 11 that engineers now estimated the spacecraft had enough propellant for 48 hours of operations, an increase it credited to a slowing leak rate. “A slowing leak rate is expected as the pressure drops, but there may be some change in the size of the propulsion system’s rupture as the pressure decreases or some other factor making it difficult to predict,” the company stated.
