A mini satellite weighing 1.2 kilograms will be launched from the Cape Peninsula University of Technology (CPUT) in November to collect information about space weather, it was learned on Wednesday.
Funded by the Department of Science and Technology, the satellite - ZACUBE-1-- will be South Africa's first nano- satellite running on the same amount of power used by a 5-watt light bulb, according to researchers at the CPUT.
Comparing ZACUBE-1 to Sputnik, the first satellite in the world to be launched into space in 1957, lead researcher Robert van Zyl described the nano-satellite as an evolutionary leap in space technology.
He said ZACUBE-1 cost much less and was 84 times smaller than Sputnik, tiny enough to be put on the palm of a human hand.
The satellite will travel to Russia and ultimately to space where the satellite will be released from its pod and its 10- meterantennae will be deployed to send information to receiving stations at CPUT and the town of Hermanus near Cape Town, according to the local newspaper Cape Times.
The satellite, also known as CubeSat, will be operational for between two and five years. Researchers expect the satellite to fall to the earth and burn up in about 10 to 20 years.
ZACUBE-1 is the result of 18 months of research and development by students and staff from the French South African Institute of Technology at CPUT, according to the report.

MIT-developed 'microthrusters' could propel small satellites
Boston MA (SPX) Aug 21, 2012
A penny-sized rocket thruster may soon power the smallest satellites in space. The device, designed by Paulo Lozano, an associate professor of aeronautics and astronautics at MIT, bears little resemblance to today's bulky satellite engines, which are laden with valves, pipes and heavy propellant tanks. Instead, Lozano's design is a flat, compact square - much like a computer chip - covered ... read more
