Rocket Lab launches first in-house built Photon satellite

The mission is Rocket Lab’s first full demonstration of end-to-end mission service, encompassing satellite build, launch, and on-orbit operations.

Rocket Lab has launched its first in-house designed and built operational Photon satellite, named First Light.

The move cements the company’s evolution from a launch provider to an end-to-end space solutions company that offers turnkey satellites and spacecraft components, launch, and on-orbit operations.

Launched as a technology demonstration, First Light builds upon the existing capabilities of the Electron launch vehicle’s Kick Stage with additional subsystems to enable long-duration satellite operations.

This mission is an initial demonstration of the new power management, thermal control and attitude control subsystem capabilities. By testing these systems for an extended period on orbit, Rocket Lab is building up flight heritage for future Photon satellite missions planned to low Earth orbit, the Moon, and Venus.

First Light was deployed to orbit on Rocket Lab’s 14th Electron mission, ‘I Can’t Believe It’s Not Optical’, which lifted-off from Rocket Lab Launch Complex 1 in New Zealand on August 31.

Approximately 60 minutes after lift-off, Electron deployed a 100kg microsatellite for Capella Space, an action that would typically signal the successful completion of a standard Rocket Lab mission. However, shortly after deploying the customer payload, Rocket Lab conducted an entirely new operation for the first time: Rocket Lab engineers sent a command to transition the Kick Stage into Photon satellite mode.

This action marked the first on-orbit demonstration of Rocket Lab’s Photon satellite as a two-in-one spacecraft, first using it to complete its conventional launch vehicle function to deploy customer satellites, then transitioning into a satellite to continue a standalone mission.

“We started with the launch and solved it, releasing small satellites from the time and orbit constraints experienced when flying on larger launch vehicles. Now we’ve simplified satellites too,” said Rocket Lab’s founder and CEO, Peter Beck. “Launching the first Photon mission marks a major turning point for space users – it’s now easier to launch and operate a space mission than it has ever been. When our customers choose a launch-plus-spacecraft mission with Electron and Photon, they immediately eliminate the complexity, risk, and delays associated with having to build their own satellite hardware and procure a separate launch.”

Designed for launch on Electron, as well as other launch vehicles,  ‘First Light’ paves the way for future, high-energy variations of Photon designed for lunar and interplanetary missions, including the CAPSTONE mission to the Moon for NASA in early 2021.

Lifting off from Launch Complex 2 in Virginia, Rocket Lab will use the Electron rocket and Photon Lunar spacecraft to launch NASA’s Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) CubeSat to Near Rectilinear Halo Orbit (NRHO), the same orbit planned for Artemis.
