Satellite docking plate for use in on-orbit servicing of spacecraft by Astroscale

Docking plate made by Astroscale for use in on-orbit servicing in space. This docking plate is designed to be integrated into a spacecraft prior to launch during the assembly, integration and test process. It will eventually be used in conjunction with Astroscale's ELSA-M satellite which can grab or dock with the docking plate on the spacecraft and provide in-orbit services such as refuelling, refurbishments or relocation. It can also provide end of life removal which would de-orbit the satellite so it burns up in the Earth's atmosphere. The markings on the top are called fiducial markers and these, along with retroreflectors help to guide navigation when docking. The plate also has a knurled reinforced rim which allows for robotic grappling technology. The plate is compatible with magnetic and robotic capture mechanisms. It is designed to be lightweight, compact and minimally intrusive since weight and volume are so critical for satellites.

This is one example of the way that companies are thinking about space sustainability and preventing future build up of further space debris. While this does not solve the current space debris problem, it does provide an option for not only de-orbiting satellites when they reach the end of their life, but also for potentially prolonging the life of satellites through refuelling and refurbishment. ELSA-d was the successful demonstration mission that took place in 2021. The next phase, ELSA-m, is due to launch in 2025.
