Space and satellites 2024 — During the visit to the Naval Hill Planetarium, were from the left, Dr Mart-Mari Duvenhage and Prof Matie Hoffman from the UFS Department of Physics, Consul General Stephanie Bunce and Vanessa Toscano from the US Consulate, and Dinah Mangope from the Department of Physics.

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 researchers receive awards from the NSTF

The University of the Free State (UFS) last week received two prestigious awards from the National Science and Technology Forum (NSTF) during its tenth gala-awards ceremony held in Kempton Park.

Prof. Maryke Labuschagne from the Department of Plant Sciences at the UFS was the female recipient of the research capacity-development award over the last ten years. She received the award for her successful mentoring of black researchers and students. The award, sponsored by Eskom, includes a prize of R100 000 which will be used for research purposes.

A team consisting of Prof. Jan van der Westhuizen and Dr Susan Bonnet from the Department of Chemistry at the UFS and Prof. Kenneth Swart and Prof. Thinus van der Merwe from FARMOVS–PAREXEL received the innovation award for an outstanding contribution to science, engineering and technology from either an individual or a team over the last ten years.

Prof. Labuschagne, an expert in the field of plant breeding and food security in Africa, received the award for her contribution to the training and development of black students and researchers in this field. Various black students successfully completed their postgraduate studies under her guidance at the UFS during the past ten years, with positive results.

Research by her South African students has led to a firmly entrenched research relationship between the Agricultural Research Council (ARC) and the UFS, while research by her local and international students has culminated in no less than 82 publications over the last decade.

It has also led to the establishment of collaboration agreements with universities and research institutes in Malawi, Kenya, Uganda and Tanzania – among others with the University of Malawi where Prof. Labuschagne and her students are involved in the International Programme in the Chemical Sciences (IPICS) of the Uppsala University in Sweden. The project focuses on the study of genetics and chemistry of tropical roots and tuber crops in Malawi. This has led to collaboration with international research organisations and has generated overseas funding.

The combined team from FARMOVS–PAREXEL and the UFS won an award for the synthesis of drug analogues used as reference products during the analysis of the drug concentration in blood, from existing and new drugs registered nationally and internationally.

The project resulted in capacity building in synthetic organic chemistry, mass spectrometry and chromatography: Five master’s degrees were completed, seven are in progress, and six postgraduate students commenced with Ph.D.’s.

The skills transferred during this project are already being applied to examine the properties of indigenous medicinal plants as part of the recently established UFS novel drugs and bioactive compound cluster.

Applied Biosystems, the Canadian manufacturer of mass spectrometers, donated equipment to the value of more than R10 million for this project. As a result the UFS is one of the few universities in the world that can offer postgraduate training in bioanalytical chemistry.

Prof. Hendrik Swart, head of the Department of Physics at the UFS, and Dr Martin Ntwaeaborwa, senior lecturer at the Department of Physics were finalist in the research- capacity developer and black-researcher categories respectively.
The NSTF awards gives recognition to the outstanding contributions of individuals and groups to science, engineering and technology. This includes all practising scientists, engineers and technologists across the system of innovation, including, for example, teachers and students in mathematics, science and technology. The NSTF represents government, science councils, professional bodies, higher education, business and civil society.

Altogether nine individuals and three organisations were presented with the NSTF Awards trophy by the Minister of Science and Technology, Mr Mosibudi Mangena.
