NASA’s CAPSTONE Probe Is Officially en Route to the Moon

An essential milestone has been reached within the newly launched CAPSTONE mission, because the tiny probe, transferring in extra of 24,000 miles per hour, has escaped low Earth orbit and begun its four-month trek to the Moon.

CAPSTONE, brief for Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment, bid farewell to low Earth orbit earlier this morning, according to NASA. The 55-pound (25 kilograms) cubesat is now journeying to the Moon, the place it’ll enter right into a close to rectilinear halo orbit (NRHO) on November 13.

This is identical orbit deliberate for the upcoming Lunar Gateway; the brand new mission meant to consider the suitability of NRHO on a smaller scale. Once constructed, and as a part of NASA’s Artemis program, Lunar Gateway will likely be used to help a long run and sustainable human presence at and across the Moon.

CAPSTONE launched from New Zealand atop a Rocket Lab Electron rocket on June 28. The cubesat had been orbiting Earth whereas hooked up to Rocket Lab’s Photon higher stage. A complete of seven maneuvers have been carried out over the course of six days, throughout which CAPSTONE’s orbit was steadily lifted. CAPSTONE ultimately reached a most distance of 810,000 miles (1.3 million kilometers) from Earth, which is greater than 3 times the Earth-Moon distance. Photon launched its payload as soon as the pair reached 24,500 miles per hour (39,500 km/hr)—the velocity required for CAPSTONE to flee Earth orbit.

CAPSTONE is now on a ballistic lunar switch trajectory to the Moon, a convoluted—however environment friendly—trajectory wherein the probe will comply with “dynamic gravitational contours in deep space,” as NASA explains:

Expending little vitality, CAPSTONE will cruise alongside these contours punctuated by a sequence of deliberate trajectory correction maneuvers. At crucial junctures, CAPSTONE’s workforce at Advanced Space’s mission operations middle will command the spacecraft to fireplace its thrusters to regulate course. Terran Orbital Corporation in Irvine, California, designed and constructed CAPSTONE and developed novel know-how that permits the spacecraft to execute maneuvers whereas sustaining management of the spacecraft on thrusters solely.

When CAPSTONE catches as much as the Moon, its method will likely be completely aligned for NRHO insertion, the crux of its route. While going 3,800 miles per hour [6,116 km/hr], it’ll carry out its delicate, exactly timed propulsive maneuver to enter orbit, like a flying trapeze artist who jumps from one arc to a different with a decisive, acrobatic movement.

NRHO represents an excellent gravitational candy spot for Lunar Gateway. Here, the pull of gravity from the Earth and Moon work together to allow a near-stable orbit, “allowing physics to do most of the work of keeping it in orbit around the Moon,” according to NASA. CAPSTONE will spend six months in NRHO, throughout which period it’ll journey to inside 2,100 miles (3,400 km) of the Moon’s north pole on its close to move and 47,000 miles (76,000 km) from the south pole at its most distant.

In addition, CAPSTONE will check a navigational system wherein the probe will measure its location relative to NASA’s Lunar Reconnaissance Orbiter and with out the advantage of floor stations on Earth.
