D-Sat, the first nanosatellite with the ability to remove itself from orbit in a direct and controlled way through a dedicated device at the end of its mission, was successfully launched on Friday June 23rd, 2017, from Satish Dhawan Space Centre in India atop a PSLV rocket.
The satellite, built and operated by D-Orbit LLC, is the first in-orbit demonstration of D-Orbit Decommissioning Device (D3), a smart and independent propulsive system designed to decommission a satellite with a direct and controlled propulsive maneuver at the end of a space mission even if the main satellite has become unresponsive. The same technology can be scaled up to decommission spacecraft of up to 5 tons.
"This mission is a milestone in how we deal with the problem of space debris" said Luca Rossettini, D-Orbit founder and CEO. "We believe that everything that goes up should come down as soon as it served its purpose, and we want to provide a practical and affordable solution to enable this vision. Our dream is to have a D3 installed in every new satellite by 2025."
The commercial aspect of the mission is funded through a EU Horizon 2020 grant called "SME instrument", under grant agreement No 711193 for D3 Project. The scientific part of the mission is partially funded by a crowdfunding campaign on Kickstarter accessible from the following link.
D-Orbit LLC is an Italian space system company specialized in products and services to streamline commissioning and decommissioning of satellites and constellations, reducing system complexity and cost of operation, and increasing lifetime, reliability, and revenues.
Magnetic space tug could target dead satellites
Derelict satellites could in future be grappled and removed from key orbits around Earth with a space tug using magnetic forces.
This same magnetic attraction or repulsion is also being considered as a safe method for multiple satellites to maintain close formations in space.
Such satellite swarms are being considered for future astronomy or Earth-observing missions – if their relati … read more
