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.

GEO-X SA STATEMENT

From Department of Science and Technology

 Thank you Chair

 

We would like to highlight some of the advances made by South Africa with respect to Earth Observation and our contributions to GEO vision and GEOSS.

South Africa, through the Department of Science and Technology, has made major strides in the development and implementation of the South African Earth Observation Strategy (SAEOS), which is aimed at promoting an integrated Earth observation system. The strategy, approved in October 2006 and launched during the margins of the GEO IV Plenary in Cape Town, captures the country’s response to the 10-year Implementation Plan for a Global Earth Observation System of Systems (GEOSS). The SAEOS Earth Observation Data Centre and the web-based Portal have been developed and are currently being operationalised and institutionalised. The Portal is integrated to the GCI and contributed resources to the GEOSS Data-CORE. South Africa strongly believes that the SAEOS model could form the basis for other African EO strategies.

Chair

National Communities of Practice have been established and these have been encouraged to contribute to GEO Work Plan and activities. South Africa is now active in 19 GEO tasks and is lead of 4 components. For a country with limited resources and capacity, this is a significant contribution. South Africa – through NEOSS, has also played a significant support role in launching AfriGEOSS and promoting the initiative within the GEO community and in other relevant platforms. Furthermore, South Africa is involved in (and will continue to be involved in) initiatives such as the Africa Working Group on Land Cover Mapping, GEO Global Agriculture Monitoring (GEOGLAM), Blue Planet, GEO Global Biodiversity Network (GEOBON), African Water Cycle Initiative and GEO Common Infrastructure (GCI). In all these initiatives South Africa has both contributed and benefited from its participation.

With further development and enhancement of the SAEOSS Portal, South Africa continues to contribute to data discovery and access of space, aerial and in-situ datasets.

Chair

The Research and Development institutions in South Africa like the CSIR, are actively applying the standards and interoperability philosophy promoted by GEO such that important locally produced datasets can be freely shared and accessed. For example, through Sensor Web Enablement Southern Ocean datasets that were not previous openly available have been incorporated into SAEOSS. GEO-Spatial infrastructure that can be shared and accessed across the continent has been established at the CSIR and is used to host data and operational services accessible to all. Our institutions are also actively working on Earth Observation projects with many of our other African partners and are making use of GEO led innovations like GEONETCAST together with mobile technology to provide access to EO services as a way to deal with infrastructure challenges.

Release: CME from Sun heads toward Earth

on . Posted in SANSA Space Science News

Solar flare1

Active region 1944 erupted on 7 January 2014 with an X-class X-ray solar flare accompanied by a coronal mass ejection (CME). The CME is travelling towards Earth and is estimated to impact the Earth's magnetic field around 9:00 UT on 09 January 2014. Based on time/height measurements of SOHO/LASCO data the initial CME speed is estimated at ~2353 km/s. The impact of the CME could spark a strong geomagnetic storm through 9 - 10 January 2014 and will be monitored by the South African National Space Agency (SANSA).

A CME is a massive cloud of high energy particles ejected from the surface of the Sun when stored energy is suddenly released. When the magnetic field of a CME interacts with the Earth's magnetic field it causes a temporary disturbance know as a geomagnetic storm.

The impact of a CME will not harm humans and other life forms on Earth as we are protected by the Earth's magnetic field. However it can cause disturbances to our satellite communication systems like GPS, radio communications, internet, cell phones and DStv. Major disturbances are expected at this stage.
