An ongoing propellant leak is causing the spacecraft’s Attitude Control System (ACS) thrusters to operate well beyond their expected service life cycles to keep the lander from an uncontrollable tumble. If the thrusters can continue to operate, we believe the spacecraft could continue in a stable sun pointing state for approximately 40 more hours, based on current fuel consumption.
At this time, the goal is to get Peregrine as close to lunar distance as we can before it loses the ability to maintain its sun-pointing position and subsequently loses power.
