South Africa’s first government-owned satellite was scheduled to be launched later on Tuesday from the Central Asian republic of Kazakhstan aboard a Russian rocket.
The R26-million SumbandilaSat will be piggybacking on a Soyuz rocket, which will blast off at 8.55pm local time from the Baikonur cosmodrome in Kazakhstan to launch a Russian weather satellite called Meteor.
The 81kg satellite, which will orbit 500km above the equator and pass over South Africa four times a day, will collect images for use by the government in agriculture, water management, urban planning and other domains.
Commissioned by the Department of Science and Technology from a company in the Western Cape, SumbandilaSat, which means ”to lead the way” in TshiVenda, was originally supposed to be launched in 2006 from a Russian rocket over the Barents Sea.
But ”geopolitical issues” torpedoed that launch, according to Khalid Manjoo, team leader for assembly, integration and testing at SunSpace & Information Systems, the company that built the satellite.
The United States was concerned about a Russian rocket being launched into orbit over its territory and Russia had to cancel the launch.
The project lay dormant until mid-2008 when South Africa and Russia signed a new agreement on space cooperation.
Russia is also cooperating with South Africa on the establishment of South Africa’s own space agency, which is expected to be launched by the end of the year.
This is the first government satellite in Southern Africa. Egypt and Nigeria have also launched satellites. South Africa’s first satellite, SunSat was launched in 1999 as an experiment by the University of Stellenbosch and exhausted its lifetime in space two years later.
While SumbandilaSat will serve South Africa first and foremost, it can also be used to view ”any part of Southern Africa, or the world,” said Manjoo.
South Africa’s ultimate aim is the creation of a constellation of satellites for disaster management in Africa, according to Manjoo. ”This would be a technology demonstrator,” he says.
The satellite’s main imager, which has multispectral imaging, has a ground resolution of 6,25m. – Sapa-DPA
