The South African National Space Agency (SANSA) was established in 2010. Following a period of rapid growth and transition the agency has made significant advancements towards addressing its mandate of deriving greater value from space science and technology for the benefit of South African society.

Next generation technology could result in cheaper satellite communication

on . Posted in SANSA Space Operations News

On 27 February 2015, SANSA will support its first Solar Electric Propulsion (SEP) mission. A SEP satellite extends the length and capabilities of the space mission while reducing costs. This in turn, could result in the form of cheaper satellite services such as television and internet data.

SEP is a NASA initiative which involves high power; high-efficiency solar electric propulsion systems requiring much less propellant than a comparable, conventional chemical propulsion system. "Simply put, instead of using fuel, these satellites make use of large solar panels and the sun's energy to boost them in space," says Tiaan Strydom, SANSA's Business Development Manager. "Think of a car. When it runs out of fuel, you have to refuel it or your journey ends. Using SEP means the energy source never runs out and therefore your journey can go on and on and on."
