Rocket Lab Sets Launch Window for Astroscale Orbital Debris Inspection Demonstration Mission
The highly responsive mission aims to demonstrate new orbital debris inspection technologies for space sustainability
Long Beach, California. February 7, 2024 – Rocket Lab USA, Inc. (Nasdaq: RKLB) (“Rocket Lab” or “the Company”), a global leader in launch services and space systems, today announced it has set the launch window for Astroscale’s orbital debris inspection demonstration mission.
The ‘On Closer Inspection’ mission is scheduled to launch during a 14-day window that opens on February 19th NZDT. The mission will lift-off from Rocket Lab Launch Complex 1 in New Zealand and will deploy the Active Debris Removal by Astroscale-Japan (ADRAS-J) satellite for Astroscale Japan Inc. The mission is the first phase of an orbital debris removal program, and during this phase ADRAS-J is designed to test technologies and operations for approaching and monitoring debris objects, also known as space junk, and delivering data that will assist in removing it, to ensure the sustainable use of space for future generations.
After launching on Electron, the 150-kilogram ADRAS-J satellite will 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. After deployment from Electron, Astroscale’s full mission will take between three and six months to complete.
To enable the rendezvous with a non-cooperative space object requires a dedicated launch, highly responsive mission planning and extremely tight margins on orbital parameters. Rocket Lab only received the final perigee, apogee, and inclination from Astroscale 20 days before launch. Only then could argument of perigee targets for different days within the 14-day 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 also demands highly accurate orbital insertion with tighter margins than required on most standard missions. In addition, the exact T-0 will only be defined the day prior to launch and the required LTAN accuracy only allows for +/- 15 seconds.
“Electron is really the only vehicle capable of delivering such a complex mission on an expedited timeline,” said Rocket Lab Founder and CEO Peter Beck. “With a dedicated launch on Electron the Astroscale team have a high degree of control over launch time and deployment parameters, and the Kick Stage delivers critical manoeuvrability for precise orbital deployment. We’re immensely proud to be working with the Astroscale team in support of a pivotal mission that could have real, positive benefits for managing space sustainability for future generations.”
“We are proud to join forces with Rocket Lab to launch the world’s first attempt to safely approach a piece of large debris,” said Astroscale Founder & CEO, Nobu Okada. “ADRAS-J is a testament to our commitment to technological innovation and to fostering the growth of the on-orbit servicing sector. This mission holds immense significance, not just for the future of space sustainability, but for pioneering advancements in Rendezvous and Proximity Operations, which are essential technologies to deliver any on-orbit servicing such as debris removal.”
‘On Closer Inspection’ will be Rocket Lab’s 2nd launch in 2024 and the 44th Electron mission overall.
