Sirin Finney Creator Invests In Effective Space

Space drone is to be launched in 2020.

Effective Space is developing a small spacecraft they call the Space Drone. It has a non-intrusive docking system that also provides maintenance and monitoring of the drone by performing attitude control, orbit correction, orbital station keeping and more. Space Drone is a satellite servicing vehicle by the Israeli company Effective Space Solutions, which will dock with their customer’s existing satellites to provide stationkeeping and attitude control capabilities.
According to Singulariteam, Chairman and Co-Founder of Sirin Labs, Kenes (Kenges) Rakishev intends to invest $6-8 million in the Israeli company. Kenes fund owns 30% of Effective Space stocks at the moment.

In March 2018 the company signed a contract over the launch of two of its Space Drone satellite life extension vehicles as secondary payloads on a Proton-M Briz-M (Ph.4) in 2020, which will deliver them directly into geostationary orbit.

Space Drone is a 400 kilogram spacecraft designed to dock with existing satellites that are running low on fuel but are otherwise operational. The spacecraft, launched as a secondary payload, uses electric propulsion to maneuver to its target satellite, attaching to the satellite’s launch vehicle interface ring via four robotic arms.

There are more than 500,000 pieces of junk floating around Earth’s orbit, including defunct satellites, rocket boosters, nuts and bolts, all of which pose a substantial threat to astronauts and spacecraft, according to U.S. space agency NASA. The European Space Agency states that as of January 2018, there are about 29,000 objects larger than 10 centimeters, around 750,000 objects that range between 1 cm to 10 cm and about 166 million objects between 1 millimeter to 1 cm in size. All this junk can damage or even destroy on-orbit facilities. One of Space Drone responsibilities is stationkeeping and, basically, cleaning.
