Reference excerpt

The South African National Space Agency (SANSA) is South Africa's government agency responsible for the promotion and development of aeronautics and aerospace space research. It fosters cooperation in space-related activities and research in space science, seeks to advance scientific engineering through human capital, as well as the peaceful use of outer space, and supports the creation of an environment conducive to the industrial development of space technologies within the framework of national government. SANSA was established on 9 December 2010 by the National Space Agency Act. Currently, SANSA's main focusses include using data obtained from remote sensing through satellites and other projects to provide assessment on flooding, fires, resource management and environmental phenomena in South Africa and the African continent.

History

SANSA was formed after an act of parliament was passed by acting President Kgalema Motlanthe in 2009. The agency was formed with the intent of consolidating space-related research, projects and research in South Africa and to assume the role as a regional centre for space research in Africa. Throughout the 1950s to 1970s lunar and interplanetary missions conducted by NASA had been supported from a tracking station at Hartebeesthoek where the first images of Mars were received from the Mariner IV spacecraft in the first successful flyby of the planet. Other South African facilities also assisted in tracking satellites to determine the effects of the upper atmosphere on their orbits. In 1980s work on the development of a launcher and a satellite had been in progress but was discontinued after 1994. In 1999, South Africa launched its first satellite, SUNSAT from Vandenberg Air Force Base in the US. A second satellite, SumbandilaSat, was launched from the Baikonur Cosmodrome in Kazakhstan in 2009.

Mission SANSA's mission is to use space science and technology to:

Deliver space-related services and products to the citizens of South Africa and the region. Support, guide and conduct research and development in space science and engineering and the practical application of the innovations they generate. Stimulate interest in science and develop human capacity in space science and technologies in South Africa. Create an environment that promotes industrial development. Nurture space-related partnerships to enhance South Africa's standing in the community of nations.

South African National Earth Observation Strategy SANSA is a key contributor to the South African Earth Observation Strategy (SAEOS), for which the primary objective is "to coordinate the collection, assimilation and dissemination of Earth observation data, so that their full potential to support policy, decision-making, economic growth and sustainable development in South Africa can be realised." SANSA will provide space-based data platforms that focus on in-situ Earth observation measurements in collaboration with entities such as the South African Environmental Observation Network (SAEON).

SANSA Space Weather Centre SANSA Space Science is host to the only Space Weather Regional Warning Centre in Africa, which operates as part of the International Space Environment Service (ISES). The Space Weather Centre provides an important service to the nation by monitoring the sun and its activity to provide information, early warnings and forecasts on space weather conditions. The space weather products and services are required primarily for communication and navigation systems, in the defence, aeronautics, navigation and communication sectors.

Worked examples

Example 1 — a first encounter with South African National Space Agency

Start with the simplest possible case. Write down what South African National Space Agency claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to South African National Space Agency before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about South African National Space Agency ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of South African National Space Agency

In research: South African National Space Agency appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses South African National Space Agency in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: South African National Space Agency is common in secondary-school and first-year university syllabi. It links to neighbouring topics Government agencies established in 2010, Space agencies, Space programme of South Africa, so understanding it makes those chapters shorter.
In everyday life: Look for South African National Space Agency outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
