Rocket Lab has launched 11 missions to date using the 57-foot-tall Electron, a vehicle designed to loft small satellites rapidly, efficiently, and relatively cheap. All of those flights went to Earth's orbit, however, so CAPSTONE will mark a big leap for the company
FREMONT, CA: The California-based company, Rocket Lab, has won a NASA contract to launch a tiny cubesat toward the moon. The 55-lb Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment spacecraft, or CAPSTONE, is scheduled to lift off atop a Rocket Lab Electron booster in early 2021.
The launch will take place from Rocket Lab’s pad at the Mid-Atlantic Regional Spaceport (MARS), located at NASA’s Wallops Flight Facility in Virginia. CAPSTONE will be the second lunar probe to depart from Virginia, after NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE), which lifted off from MARS in September 2013.
After the two-stage Electron gets CAPSTONE aloft, Rocket Lab’s Photon satellite bus will fire up its onboard engine, sending the cubesat on a long journey toward the moon. About three months later, CAPSTONE will get itself into a highly elliptical “rectilinear halo orbit” around Earth’s nearest neighbor, the same orbit targeted for Gateway, the small space station NASA plans to build as part of its Artemis lunar-exploration program.
“CAPSTONE is a rapid, risk-tolerant demonstration that sets out to learn about the unique, seven-day cislunar orbit we are also targeting for Gateway,” said Marshall Smith, director of human lunar exploration programs at NASA headquarters in Washington. “We are not relying only on this precursor data, but we can reduce navigation uncertainties ahead of our future missions using the same lunar orbit.”
The MARS facility is Rocket Lab’s second launch complex. The first, on New Zealand’s North Island, has supported all 11 Electron liftoffs to date.
Electron is currently an expendable vehicle, but Rocket Lab plans to begin recovering and reusing the booster’s first stage. The company successfully guided the first stages back down toward Earth during the last two Electron launches and may soon take the next step: attempting to snag a falling booster out of the sky with a helicopter.
“Small satellites like CAPSTONE will play a crucial role in supporting the return of human missions to the moon, and we’re proud to be supporting NASA in this unique and pivotal mission,” said Rocket Lab founder and CEO Peter Beck. “In the same way we opened access to low Earth orbit for small satellites, we’re proud to be bringing the moon within reach to enable research and exploration.”
