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.

UFS gets more than R3 Million for HIV/Aids activities

UFS gets more than R3 Million for HIV/Aids activities

The Chief Directorate: Community Service at the University of the Free State (UFS) has received more than R3 million to intensify activities regarding HIV/AIDS at all UFS campuses for the next seventeen months.

Higher Education HIV/AIDS Programme (HEAIDS) contributed R3 127 207 and the UFS R615 116 towards this initiative. The money will be used to implement intervention strategies from 1 January 2008 to 31 May 2009.

“The mandate poses an extensive challenge and puts pressure on the institution, but at the same time creates some incredible opportunities for intervention,” said the Chief Director of Community Service and Project Co-ordinator, Rev. Kiepie Jaftha.

HEAIDS is a nationally co-ordinated initiative to develop and strengthen the capacity of South African higher education institutions to respond to the causes, challenges and consequences of the HIV/AIDS pandemic in the sector. It is an initiative of the Department of Education and the implementing agency is Higher Education South Africa (HESA), an organisation representing vice-chancellors of tertiary institutions in South Africa.

The proposed areas and actions of intervention are categorised into three main components, namely:

- Prevention, treatment, care and support aimed at both students and staff on all UFS campuses.
Incorporation of HIV/AIDS issues into the teaching offerings of the UFS and the development of a formal policy in this regard.

- Implementation of an integrated management information system to empower stakeholders to make decisions and adapt actions by visualising facts, actions and progress on the overall HIV/AIDS programme.

The UFS met all the requirements of HEAIDS to qualify for this funding. A five-member team was formed to come up with a document entitled The Quest for an AIDS Competent Society that met the required standards.

“Each institution of higher learning had to identify and establish a project team, appoint a project leader, assign responsibilities to members of the team with different expertise, analyse the needs of the institution, and define and agree on projects in order to access the grant,” said Rev. Jaftha.
