Almost five months after a successful launch by Rocket Lab, the CAPSTONE spacecraft has reached its lunar destination - a unique orbit around the Moon where the future Gateway space station will support NASA's Artemis missions

Rocket Lab USA, Inc. (Nasdaq: RKLB) (“Rocket Lab” or “the Company”), a leading launch and space systems company, is celebrating the successful arrival of the Electron-launched, Photon-deployed CAPSTONE spacecraft to lunar orbit. Following an initial orbit insertion maneuver on Sunday, CAPSTONE will perform clean-up maneuvers over the next several days to complete insertion into its target orbit. CAPSTONE (Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment) has been travelling in space for almost five months following a successful launch by Rocket Lab on June 28, 2022.

CAPSTONE is owned and operated by Advanced Space; CAPSTONE’s primary mission is to test a unique, elongated lunar orbit, formally known as near-rectilinear halo orbit (NRHO), as a pathfinder for Gateway, a Moon-orbiting space station that is part of NASA’s Artemis program which will ultimately pave the way for human exploration of the Moon, Mars and beyond.

CAPSTONE was launched to low Earth orbit from Rocket Lab’s Launch Complex 1 on June 28 on the Electron launch vehicle. From there, Rocket Lab’s Lunar Photon spacecraft carried out a series of obit raising maneuvers over six days, pushing CAPSTONE deeper into space before conducting a final maneuver to place CAPSTONE on a ballistic lunar transfer. This maneuver saw CAPSTONE travel more than 1.5 million kilometers from Earth before looping back to be captured by the Moon’s gravity and reaching its final planned destination in near rectilinear halo orbit. Rocket Lab’s role in the mission was successfully completed on July 4^th with the injection of the spacecraft onto the ballistic lunar transfer designed by Advanced Space. Advanced Space and Terran Orbital managed operations of CAPSTONE for the remainder of the spacecraft’s solo journey to lunar orbit.

“Congratulations to the many teams behind mission success for CAPSTONE. This is a monumental day for small spacecraft science and exploration,” said Rocket Lab Founder and CEO Peter Beck. “After delivering a successful launch and deployment for CAPSTONE almost five months ago, we’ve watched with bated breath as CAPSTONE drew closer to lunar orbit. Throughout that time the teams at Advanced Space and Terran Orbital have shown relentless dedication, culminating in mission success today. We’re cheering CAPSTONE on as it now transitions into the next phase of operations in lunar orbit.”

About Rocket Lab

Founded in 2006, Rocket Lab is an end-to-end space company with an established track record of mission success. We deliver reliable launch services, satellite manufacture, spacecraft components, and on-orbit management solutions that make it faster, easier and more affordable to access space. Headquartered in Long Beach, California, Rocket Lab designs and manufactures the Electron small orbital launch vehicle and the Photon satellite platform and is developing the large Neutron launch vehicle. Since its first orbital launch in January 2018, Rocket Lab’s Electron launch vehicle has become the second most frequently launched U.S. rocket annually and has delivered 152 satellites to orbit for private and public sector organizations, enabling operations in national security, scientific research, space debris mitigation, Earth observation, climate monitoring, and communications. Rocket Lab’s Photon spacecraft platform has been selected to support NASA missions to the Moon and Mars, as well as the first private commercial mission to Venus. Rocket Lab has three launch pads at two launch sites, including two launch pads at a private orbital launch site located in New Zealand and a second launch site in Virginia, USA which is expected to become operational in 2022.
