Space and satellites 2024

A delegation from the United States (US) Consulate General in Johannesburg, including Consul General Stephanie Bunce and Public Affairs Officer, Vanessa Toscano, visited the Bloemfontein Campus of the University of the Free State (UFS). Consul General Bunce met with the acting Vice-Chancellor and Principal of the UFS, Prof Anthea Rhoda, and the Dean of the Faculty of Natural and Agricultural Sciences, Prof Paul Oberholster. The US delegation also visited the Naval Hill Planetarium.

The UFS recently received a grant from the US Embassy to fund a project to promote science education by highlighting the role of satellites in our lives. Colleagues from the Department of Physics had the opportunity to demonstrate first-hand how the planetarium technology will be used to implement the project, which poses the question – what if something happens in space that interferes with the thousands of satellites we use for communication, weather prediction, navigation, banking … surveillance?

Thanks to this grant, the UFS will explore these questions and contribute to space situational awareness (SSA) and space domain awareness (SDA). SSA involves knowledge about the orbits of spacecraft and space debris. SDA refers to the knowledge and understanding of all activities occurring within the space domain.

There are currently at least 10 000 active satellites in Earth orbit, most of which are in low Earth orbit (LEO). However, in addition to satellites, there are well over 45 000 objects larger than 10 cm in orbit, including more than 35 000 pieces of space debris, such as dead satellites, rocket bodies, and pieces from breakups and collisions. Since 1991, there have been at least six unintentional collisions between active satellites and space debris.

Space turned out to be not as big as once thought, especially not in low Earth orbit (LEO – altitude less than 2 000 km). To make things worse, there are plans to launch up to 100 000 new satellites into LEO over the next decade.

Prof Matie Hoffman from the UFS Department of Physics notes, “We live in an era when the space economy is growing fast and the number of objects in Earth orbit, including satellites and space debris, is increasing rapidly. This poses risks to operational satellites. Recent publicity around Elon Musk’s Starlink satellites has generated additional interest around this topic. It is important to raise awareness of the challenges, which will allow scientists to mitigate them.”

The project will involve expertise in optical satellite observations from the University of Michigan through Prof Patrick Seitzer, international patron of the Friends of Boyden Observatory, and the American Museum of Natural History (AMNH). The grant will fund planetarium upgrades that will enable education on space and satellites, as well as optical satellite observations from Boyden Observatory. Beneficiaries will include learners, higher education institutions (both locally and in the US), and the public. South African project partners will be the South African National Space Agency (SANSA), the Future African Space Explorers’ STEM Academy (FASESA), and satellite-related companies in South Africa.

The Boyden Observatory is ideally situated to provide valuable optical satellite observations in an area of the sky that is not accessible from existing satellite observing facilities, especially for objects in LEO. In fact, the first observation of space debris in geosynchronous orbit was from Boyden Observatory in 1967.

The project will be rolled out from the end of 2024, harnessing facilities at both Boyden Observatory and the Naval Hill Planetarium.

CR Swart Memorial Lecture: Mr Cecil le Fleur
2006-08-08

Khoe and San call for government to speed up policy dialogue with indigenous communities  

 Mr Cecil le Fleur, leader of the National Khoe-San Consultative Conference and member of the executive management of the National Khoe-San Council, has called for a national policy on indigenous peoples to protect the human rights and special needs of indigenous people in South Africa.

 Mr Le Fleur delivered the 38th CR Swart Memorial Lecture on the Khoe and San at the University of the Free State (UFS).  He commended the UFS for its serious approach to the Khoe and San and for initiating initiatives such as a research project on the Griqua in which various aspects linked to language, -culture, -history, - leadership, their role in the South African community (past and present) and the conservation of their historical cultural heritages will be covered.   

 “The policy dialogue with indigenous communities initiated by government in 1999 and supported by the International Labour Organisation (ILO), has been exceedingly slow, owing to political and bureaucratic problems,” said Mr Le Fleur.

 According to Mr Le Fleur the slow pace is also impacting negatively on the United Nations’ efforts to expand the international standards and mechanisms for human rights so as to include the special needs of indigenous peoples.

 “The successful adoption of a South African policy would probably have a major impact on the human rights culture of Africa and, more specifically, on the UN system,” he said.

 “South Africa has a powerful moral authority internationally and is willing to use this authority in multilateral forums. At this stage, however, South Africa’s Department of Foreign Affairs (DFA) may not take an official position on UN instruments and declarations pertaining to indigenous issues, until the Cabinet has resolved its own domestic policy position,” he said. 

 According to Mr le Fleur it therefore came as a great surprise when the DFA brought out a positive vote in the UN for the adoption of the "Draft Declaration on the Rights of indigenous Peoples" in June this year, even before the completion of the policy process. 

 Policy consolidation in South Africa is the primary key to creating a new policy climate in Africa in order to protect the rights of indigenous peoples.  “The existing constitution of the Republic of South Africa is one of the most liberal on the continent, and embraces the concept of redress of past discrimination.  It already includes a clause (Section 6) making provision for the protection of language rights for Khoe and San peoples - the fist peoples of southern Africa,” he said. 

 “If South Africa can effectively integrate this ‘third generation’ of collective rights within an existing democratic constitution, this will send a clear message to Africa and the world that indigenous rights are a necessary component of human and civil rights in modern democracies,” he said.

 Mr Le Fleur proposed an institutional framework based on set principles that would satisfy the needs and aspirations of the Griqua and other first indigenous peoples in South Africa.  “The proposed framework was based on the notion of vulnerability as a result of colonialism and apartheid, which stripped us of our indigenous identity, cultural identity and pride as people.  This injustice can hardly be addressed within the existing mechanisms provided by the current text of the Constitution,” he said.

 Mr Le Fleur also proposed that the principles of unique first-nation status, as recognised in international law, should be applied in the construction of the framework of the constitutional accommodation for the Khoe and San. 

 Mr Le Fleur further proposed that the Khoe and San’s indigenous status in constitutional terms must be separate from the constitutional acknowledgement of their status as a cultural community, as envisaged in sections 185 and 186 of the Constitution of 1996.

 According to Mr Le Fleur, the suggested mechanism should make provision for structures such as:

  •  A statutory representative council for First Indigenous Peoples of South Africa at a national level;
  • a separate Joint Standing Committee on Indigenous and Traditional Affairs, in both the National Assembly and the National Council of Provinces on which the Khoe and San can be represented;
  • a representative structure for the Khoe and San in the legislature of each relevant province; and
  • ex officio membership in the relevant structures of local government.
