NASA’s little CAPSTONE spacecraft has hit one other hurdle on its lengthy street to the moon.
Towards the top of a serious engine burn on Thursday night (Sept. 8), the 55-pound (25 kilograms) CAPSTONE skilled an anomaly that put the probe in a protecting “protected mode,” mission staff members stated.
The glitch “resulted within the car angle [orientation] charges rising past the capability of the onboard response wheels to manage and counter,” representatives of the Colorado firm Superior House, which operates the CAPSTONE mission for NASA, wrote in an replace on Monday (opens in new tab) (Sept. 12).
“The car was making an attempt to speak with the bottom for about 24 hours earlier than any telemetry was recovered,” they added. “On the level of restoration, the spacecraft was not in a steady configuration, it was not energy constructive and the system was experiencing periodic resets.”

CAPSTONE staff members have been working across the clock since then to cope with the still-mysterious downside, based on the replace, they usually’ve made some progress. For instance, the staff has reconfigured the “operational state” of the spacecraft, serving to to stabilize the state of affairs. CAPSTONE can also be now energy constructive, which means its photo voltaic arrays are producing extra vitality than the probe is consuming.
The mission staff continues working to diagnose the issue, “enhance the thermal state of affairs” of a few of the spacecraft’s subsystems and put together for a coming “detumble” operation.
“A profitable detumble will end result within the car resuming management of its orientation, orienting the photo voltaic panels to the solar to totally cost the batteries of the facility used through the detumble,” the replace states. “The spacecraft will then orient to the bottom and await additional directions. These restoration operations can be additional evaluated over the approaching days.”
CAPSTONE, which is concerning the dimension of a microwave oven, launched atop a Rocket Lab Electron booster on June 28. The spacecraft is headed to the moon — particularly, a lunar close to rectilinear halo orbit (NRHO), the identical one which can be utilized by NASA’s Gateway house station within the coming years.
CAPSTONE will confirm the presumed stability of the NRHO forward of the arrival of Gateway, which is a key a part of NASA’s Artemis moon program. The cubesat may even conduct navigation and communications experiments, a few of them in cooperation with NASA’s Lunar Reconnaissance Orbiter.
CAPSTONE’s journey is an extended one; it isn’t scheduled to succeed in its lunar vacation spot till Nov. 13. Thursday’s engine burn helped hold it on course for that arrival date. As a result of Thursday’s anomaly occurred close to the top of the maneuver, it seems CAPSTONE stays on its designated course, based on Monday’s replace.
CAPSTONE has battled by way of an anomaly already: It went darkish simply after deploying from Rocket Lab’s Photon spacecraft bus on July 4. The mission staff managed to repair that downside, which was brought on by an improperly formatted command, a day later.
