Rocket Lab Successfully Launches Mission Designed to Investigate Removing Space Junk from Orbit

Rocket Lab’s Electron rocket successfully deployed the ADRAS-J satellite for Astroscale Japan Inc to conduct an orbital debris inspection demonstration mission.

Rocket Lab USA, Inc. (Nasdaq: RKLB) (“Rocket Lab” or “the Company”), a global leader in launch services and space systems, today launched its 44^th Electron rocket, successfully deploying an orbital debris inspection satellite for Astroscale Japan Inc.

The mission, named “On Closer Inspection”, launched from Pad B at Rocket Lab’s Launch Complex 1 in New Zealand at 03:52 NZDT February 19^th, 2024 (14:52 UTC, February 18^th). Electron deployed the Active Debris Removal by Astroscale-Japan (ADRAS-J), a satellite designed to test technologies and operations for approaching and monitoring debris objects in orbit, also known as space junk. The mission is the first phase in assessing the potential for satellites to rendezvous with orbital debris objects in future and assist in de-orbiting them, supporting space sustainability for future generations.

Following the successful launch on Electron, the 150-kilogram ADRAS-J satellite will now approach an aged, derelict rocket stage in orbit to observe it closely, understand how it behaves and determine potential methods for its assisted deorbiting in future. The rocket stage it will be observing is the Japanese H-2A upper stage left in low Earth orbit after the launch of the GOSAT Earth observation satellite in 2009. ADRAS-J will fly around the stage, 11 meters long and four meters in diameter, inspecting it with cameras and sensors. Astroscale’s full mission will take between three and six months to complete.

“Congratulations to the Astroscale team on this historic mission that paves the way for new and innovative ways to reduce orbital debris and ensure space remains safely accessible,” said Rocket Lab founder and CEO Peter Beck. “It’s a real honor to provide a dedicated launch service and enable the kind of precise orbital maneuvers required for an advanced mission like this.”

To enable the ADRAS-J satellite to rendezvous with the derelict H-2A upper stage in orbit, Rocket Lab had to design a mission with strict launch timing and precision orbital deployment parameters. Rocket Lab only received the final perigee, apogee, and inclination from Astroscale 20 days before launch, parameters that are typically determined many months in advance of a launch. Only then could argument of perigee targets for different days within the launch window be selected, essentially determining the timing of Electron Kick Stage burns to facilitate the unique elliptical orbit required depending on the launch date. The mission demanded highly accurate orbital insertion with tighter margins than required on most standard missions. The exact T-0 was only able to be defined the day prior to launch and the required LTAN accuracy only allows for +/- 15 seconds, demonstrating Rocket Lab’s capability to deliver rapid and responsive advanced guidance, navigation and control analysis.

“Today’s successful launch of ADRAS-J marks another milestone toward our efforts to grow the on-orbit servicing sector while creating a sustainable space environment,” said Astroscale founder & CEO Nobu Okada. “We are grateful for the collaboration with Rocket Lab, whose expertise in dedicated launch services has been instrumental to the start of this ground breaking mission.”
