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.

Space Talk at SANSA - Life Inside a Bubble

on . Posted in SANSA Space Science News

In 1958, a simple Geiger counter attached to a primitive rocket made a startling discovery: Space is radioactive!  Hailed as the first major discovery of the space era, it was soon realised that this observation was intimately related a number of other puzzles.  The melodious whistling tones that were sometimes heard on long wire antennae when they were attached to a loudspeaker and the bewildering events reported a century prior where telegraph wires began to generate their own electric currents. It was possible to read a newspaper by the light of the bright red aurora, even as close to the equator as Cuba.  In this talk, Dr Bortnik will briefly explain some of the background and history of space weather, and discuss a few of the questions that continue to elude space physicists today. Particular attention will be paid to results from the recently launched Van Allen Probes, which are recording in unprecedented detail the Earth's radiation environment as the Sun awakens from its long and deep solar minimum.

Fig 2The latest SPOT 5 national mosaic for 2012 has been released at an event by the South African National Space Agency (SANSA) to key stakeholders in government departments and private industry for use in addressing national requirements. 

The imagery which is collected over a period of 12 months is downloaded and processed by SANSA into the comprehensive tool which is delivered free to stakeholders who utilize this information to address issues facing South Africa, such as planning for infrastructure and housing, agriculture, water and environmental management and national census, amongst others. 

Dr Jane Olwoch, MD of SANSA Earth Observation stated, “It is a significant achievement for SANSA to be able to provide a state-of-the-art product that brings huge impact to the lives of our citizens when used by our government stakeholders.” The mosaic is made up of 485 images taken by the SPOT 5 satellite which has been processed and compiled to make up the entire map of the country. The detail within each of the tiles of the mosaic provides information of an area 60km by 60km.
