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.

The Qwaqwa Campus welcomed its new Head in the person of Prof Prakash Naidoo. Prof Naidoo, former Deputy Vice-Chancellor: Finance (Resources and Planning) at the Vaal University of Technology (VUT), received a very warm welcome from the staff, students and the Eastern Free State community.

In response to his welcoming, Prof Naidoo thanked among others, his predecessor, Dr Elias Malete, for his leadership of the campus, as well as the Head: Operations, Teboho Manchu and the Head: Academic, Dr Elsa Crause, for their support during his first few days on campus.

“I am elated to be joining an institution that is serious about transformation. There is still a lot of work ahead to make this campus the best,” said Prof Naidoo.

“Positive vibrancy exists here and all of us must begin to think about how we can multiply the effect to make it even better.”

“This year the campus is celebrating its tenth year in existence as part of the University of the Free State and we have accomplished much in this time. However, there is still a lot to accomplish in the next 10 years. We need progressive change. Let us all look ahead, but let us never forget the past.”

“Today’s students live with greater complexities, like watching too much TV and reading less. They need more counselling and guidance. In my book, students come first. Academic business comes first.”

Prof Naidoo expressed his optimism in working with all internal and external stakeholders.

“I am a team player and we must all develop a working plan for this campus,” Prof Naidoo said.

The welcoming was attended by members of the Council and the Rectorate.
