Noosphere Ventures, a California venture capital firm, has invested in Space Electric Thruster Systems, a Dnipro company that designs electro-propulsion space thrusters for satellites, Nolan Peterson reports for The Daily Sentinel. Electro-propulsion is a means of thrust that operates in the vacuum of space. Electro-propulsion thrusters are smaller and use less fuel than conventional orbital thrusters. Victor Serbin, founder and CEO of Thruster Systems, says the technology can extend orbital lifespans of geostationary satellites to 21 years, from current lifespans of 12-17 years.
