NASA’s CAPSTONE moon cubesat re-establishes contact

NASA’s tiny CAPSTONE moon probe is again in contact with its handlers, ending a brief however spooky silent interval.

The 55-pound (25 kilograms) CAPSTONE went darkish on Monday (July 4), shortly after separating from its Rocket Lab Photon spacecraft bus and heading towards the moon. The mission workforce instantly set to troubleshooting, and their efforts have already been rewarded.

“We’ve re-established communications with CAPSTONE. The spacecraft is trying pleased and wholesome. Extra particulars to come back,” Colorado-based firm Superior House, which operates the mission for NASA, said via Twitter today (opens in new tab) (July 6).

CAPSTONE launched to Earth orbit atop a Rocket Lab Electron booster on June 28, then spent per week spiraling farther and farther away from our planet by way of occasional Photon engine burns. The ultimate Photon firing, on Monday, imparted sufficient of a kick to ship CAPSTONE on its method to the moon, and the cubesat separated from the spacecraft bus shortly thereafter.

CAPSTONE then notched a number of different massive milestones in fast succession; the microwave-oven-sized craft deployed its photo voltaic arrays as deliberate, for instance, and started readying its onboard propulsion system for its first engine burn, NASA officers mentioned in an replace yesterday (opens in new tab) (July 5). CAPSTONE made contact with the mission workforce two instances by way of NASA’s Deep House Community shortly after separation, however it then went darkish, for causes that stay mysterious.

The lack of contact compelled the CAPSTONE workforce to delay the cubesat’s first trajectory-correction engine burn, which had been scheduled for yesterday. However that should not be an enormous deal; the spacecraft has sufficient gasoline to deal with a delay of “a number of days” on this preliminary burn, NASA officers mentioned in one other replace yesterday (opens in new tab).

CAPSTONE is on its method to a close to rectilinear halo orbit (NRHO) across the moon, a extremely elliptical path that NASA has chosen for its Gateway area station. No spacecraft has ever occupied a lunar NRHO, and CAPSTONE is tasked with verifying its stability for Gateway, which is a key a part of NASA’s Artemis program of moon exploration.

It will take CAPSTONE (brief for “Cislunar Autonomous Positioning System Know-how Operations and Navigation Experiment”) some time to get to its vacation spot. As a result of it launched aboard the 58-foot-tall (19 meters) Electron — a rocket designed to loft small satellites to Earth orbit — the cubesat is taking an extended, looping and extremely fuel-efficient path to the moon. If all goes in line with plan, CAPSTONE will slip into its NRHO on Nov. 13.
