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.

On 27 September 2017, on the margins of the 68th International Astronautics Conference (IAC) taking place in Adelaide, Australia, the South African National Space Agency (SANSA) and the Deutsches Zentrum fur Luft- und Raumfahrt e. V. (DLR) signed a Memorandum of Understanding (MoU).

This is the first extension of the MoU that was signed on 12 July 2012, thus confirming the party's intentions to continue with joint collaborative activities. Under the first MoU a number of successful initiatives have been implemented, which include the launch and hosting of an optical space laboratory in Sutherland, Western Cape, that will track space debris up to the geostationary orbit. In addition, an international Space Weather Camp has been initiated involving eight students each from South Africa, Germany and the United States.

SA Space Agency monitoring strongest solar flare in over a decade  

Our life giving star, the Sun, has unleashed two massive solar flares, the second of which is the strongest flare in over a decade. The burst of radiation was so intense, it caused high frequency (HF) radio blackouts across the daytime side of Earth affecting HF communication over Africa, Europe and the Atlantic Ocean.

The first flare erupted on 6 Sep 2017 from active region 2673 and measured in at X 2.2. Hot on its heels, another flare blasted off the Sun three hours later, measuring in at a whopping X 9.3 - the most powerful flare since 2005.

Solar flares are giant explosions on the surface of the Sun that occur when twisted magnetic field lines suddenly snap and release massive amounts of electromagnetic energy. Five categories — A, B, C, M and X — are used to rank solar flares based on their intensity. A-Class flares are the weakest, while X-Class are the most energetic.

The solar flares were accompanied by a coronal mass ejection (CME) which travelled towards Earth at speeds over 1200 km per second and impacted the Earth's magnetic field early morning on 8 Sep 2017. The impact of the CME has sparked a strong (G3) geomagnetic storm on Earth which can have effects on HF communication, power grids, navigation systems such as GPS, and communication systems such as DStv, mobile phones and internet connectivity. Moderate disturbances are expected at this stage. The storm will gradually subside over the next 24 hours.
