Mission To The Moon
Supporting NASA's mission to return humans to the Moon
In May 2022 Rocket Lab will launch a CubeSat to the Moon. This historic pathfinding mission supports NASA’s Artemis program which will land the first woman and first person of color on the Moon.
Using our Electron rocket and new Lunar Photon upper stage, Rocket Lab will inject the Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) CubeSat to a highly efficient transfer orbit to the Moon. CAPSTONE is owned and operated by Advanced Space in Westminster, Colorado, for NASA.
CAPSTONE’s primary objective is to test and verify the calculated orbital stability of a Near Rectilinear Halo Orbit around the Moon, the same orbit planned for Gateway. NASA’s Gateway is a small space station that will orbit around the Moon to provide astronauts with access to the lunar surface. It will feature living quarters for astronauts, a lab for science and research and ports for visiting spacecraft. CAPSTONE will also test a navigation system developed by Advanced Space that will measure its absolute position in cislunar space using interaction with NASA's Lunar Reconnaissance Orbiter without relying on ground stations for navigation support.
CAPSTONE is one of the first steps to learn how to operate more robust missions in this unique orbit, thus laying the groundwork for future exploration of our solar system.
How We're Getting There
The Electron launch vehicle is CAPSTONE’s ride to space. Launching since 2017, Rocket Lab's Electron rockets have delivered 100+ satellites to orbit on time and on target. Electron will provide the Lunar Photon upper stage and CAPSTONE CubeSat with the initial ride to low Earth orbit.
Once Electron reaches low Earth orbit, our Lunar Photon upper stage takes the reigns to deliver the CAPSTONE spacecraft onto its highly efficient ballistic transfer orbit to the Moon.
Lunar Photon, with Advanced Space’s CAPSTONE attached, will orbit the Earth in elliptical phasing orbits over nine days to build up velocity for a Trans Lunar Injection (TLI) to deploy CAPSTONE into the deep space, low energy transfer orbit to the vicinity of the Moon.
The Launch Site
CAPSTONE will be launched from Rocket Lab Launch Complex 1, located on New Zealand's Mahia Peninsula.
CAPSTONE will be the first satellite to operate in a Near Rectilinear Halo Orbit around the Moon. CAPSTONE aims to reduce risk and validate operational concepts for future missions using the same lunar orbit.
In this orbit, CAPSTONE will orbit together with the Moon as it orbits Earth and will pass as close as 1600km and as far as 70000km from the lunar surface. About the size of a microwave oven, this 25kg satellite has an onboard communications system capable of determining how far CAPSTONE is from NASA’s Lunar Reconnaissance Orbiter and how fast the distance between the two spacecraft is changing. This inter-spacecraft information will be used to demonstrate the software for autonomous navigation, CAPS, that, when fully demonstrated, will enable future missions to determine their location without having to rely exclusively on tracking from Earth.
The mission is supported by the hundreds of women and men of Rocket Lab at our Long Beach Headquarters, our launch sites and our production facilities.
Right now, and in the months to come before lift-off, our team members are building the Electron rocket for this mission, developing the Lunar Photon Lunar upper stage, designing phasing orbit mission trajectories, readying the launch pad and spacecraft integration facilities, and preparing systems for the mission.
We’re proud to be working alongside NASA and industry partners Advanced Space and Tyvak Nano-Satellite Systems to deliver this historic mission and play our part in humanity’s return to the Moon.
