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.

Natural Wonders of South Africa Series - The Richtersveld

Landsat 8 natural colour composite image showing the Richtersveld. Acquired on 19 September 2016, the 753 natural band combination shows 8,000 square kilometres of coastal plain and sandveld, and to the east of that, the true Richtersveld – 3 000 square kilometres of geologically complex desert mountainland.

Lying inland from the coast between the mouth of the Orange River and Port Nolloth, The Richtersveld is characterised by rugged kloofs and high mountains. Scant rainfall, no permanent water source, tiny stone plants found nowhere else, the unusual halfmens, and spring daisies that defy the barren rock and stone are the hallmarks of this barren beauty. Legend has it that the Richtersveld Halfmens (i.e. desert plant with the mystical name Halfmens or “Half Person”) derives its name from the ancestors of the Bushmen who were driven south by warlike tribes from the north. Some turned to look back across the Orange River and were turned into 'halfmens' (half people), forever gazing northwards.

Natural Wonders of South Africa Series - The Orange River

Landsat 8 false colour composite image showing a portion of the Orange rive. Acquired on 22 March 2016, the 564 band combination shows built-up features for Upington, Northern Cape in shades of pink, purple and grey, water in black, and healthy vegetation and irrigated fields as bright red. The heart shaped structure visible on the eastern bank is Khi One Solar, a 50 Megawatt solar power plant.

The Orange river is the longest river in South Africa. For millions of years diamonds have been carried to the Atlantic by the Orange River, making it one of the richest alluvial diamond fields in the world. As the collection point for the majority of South Africa's water, the Orange River plays a major role in supporting agriculture, industry and mining.
