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.

“My time at the UFS was the golden gem of my career”

“My time at the University of the Free State (UFS) was the golden gem of my career. I have worked at medical schools or biomedical research centres in the United Kingdom, United States and at some of the top medical schools in South Africa, but working at the UFS was one of the highlights of my career,” says Prof Alan St Clair Gibson, Head of the UFS School of Medicine.

After spending just over two years at the UFS, Prof St Clair Gibson resigned from the institution in June 2016 and will take up the position of Dean: Health and Human Performance Sciences at the Waikato University in New Zealand in mid-July, where he will assist to establish a new faculty for all the health-science disciplines. “It was a privilege to work at the UFS. I come from a strong research background and wanted to grow research at the university, which I achieved. I came to the UFS because of the Academic and Human Projects and am proud of what has been achieved at the School of Medicine during the time I was here,” he said.

Prof St Clair Gibson highlighted some of these achievements, including the development of a management infrastructure across the disciplines of the school. “The establishment of an executive management committee for the school, as well as research champions in departments, highlighted the importance of proper governance and strategic management. By developing data dashboards, my management team and I could develop an understanding of research income and productivity, how the school works, what the role of teaching and learning is, and how the school could benefit in terms of third-stream income from the many contracts obtained by its academic staff. As a result, contracts and the financial management model of the school have also been reconfigured to the benefit of the university so that the institution and school can benefit from it,” he said.

His strong belief in an open-door policy has made staff feel part of the environment and it has created an atmosphere of equality and inclusivity. He believes in staff development and has, for instance, established leadership and management courses for heads of departments. Another factor to be proud of is the increase in the number of young researchers who recently joined the school, such as Prof Ross Tucker, who is one of the foremost sport scientists in the country. “It is a fact that staff retire or resign in all schools and departments of any university. It is also true that these departures offer opportunities to bring new academic and professional staff into the UFS. In fact, for the first time virtually every department in the School of Medicine now has a full-time Head of Department and 46 new staff were appointed since January 2015,” said Prof St Clair Gibson.

“I am especially proud of contributing, together with the senior leadership of the UFS, to stabilise the relationship with the Free State Department of Health (DoH). With the assistance of these parties, as well as my executive management team, we could find a better way of working together to the benefit of the school and the province.’’

Transforming the student profile to be representative of the country’s demographics is another milestone Prof St Clair Gibson will remember. “The intake of black and white students is of such a nature that we now have a much more balanced ratio of black and white undergraduate students than before.”

“I wanted to stay longer to see the effect of all the changes I made at the school, but the deanship is an offer I cannot refuse. I would have liked to see a steadier increase in the number of permanent clinical staff and have worked hard with both the UFS management and the DoH to try and achieve that; but more work needs to be done.”

I have worked with a number of fantastic staff members at the school, who are determined to do good in a challenging environment. I am amazed at the energy of the university leadership and how the Human and Academic Projects are executed. My wish for the university is to maintain and grow its standards and for the School of Medicine to maintain its reputation as one of the best schools in the country. I will always be a proud alumnus of the UFS,” he said.
