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.

Kovsies celebrate ‘model of humanity’

The University of the Free State (UFS) joined people around the globe in celebration of the fourth annual Nelson Mandela Day. Long-time Madiba confidant, Zelda la Grange, delivered the main address, inspiring the crowd with anecdotes gleaned from her intimate knowledge of the former president.

La Grange felt that the UFS as an institution can contribute greatly towards the upliftment of South African society.

“Your university has become what we hope for in South Africa – a transformed society whose purpose serves the greater good of humanity. Embrace and nurture what you have here under the leadership of Prof Jansen and his team. And influence society consciously, every day, in the same way as Madiba did for every day of the 67 years of his activism, and beyond.”

As UFS Vice-Chancellor and Rector, Prof Jonathan Jansen, aptly put it, the Kovsie celebrations aim to give thanks to Madiba as a ‘model of humanity’ and for what he has done for all South Africans.

Prof Jansen stressed that the importance of Mandela Day cannot be overstated.

"I think it is incredibly important because the real legacy of Nelson Mandela is that of a man who gave everything he had for the struggle to gain our freedom, our democracy and that we can get along as just human beings and not as a skin colour, a religion or as strangers," he said.

Events began with a clean-up operation by UFS volunteers, Zelda la Grange and the Bikers for Mandela Day, the Mangaung Metropolitan Municipality and other sponsors. The team cleaned areas in Heidedal and Manguang before returning to the UFS Bloemfontein Campus.

Kicking off the campus section of the programme, UFS staff and students formed a ‘human chain’ on the Red Square as part of a wider initiative which was the brainchild of Archbishop Emeritus Desmond Tutu – who was the main attraction of the 2012 Mandela Day activities at Kovsies.

The assembled ‘chain’ recited the UFS Mandela Day pledge, whilst snaking around the Red Square and the gardens surrounding the Main Building, before offering interfaith prayers to Madiba in honour of the 67 minutes of selflessness epitomised by Nelson Mandela Day.

To conclude the first part of the celebrations, the No Student Hungry campaign’s patrons, Mrs Grace Jansen and Dr Carin Buys, released symbolic doves and joined the chain in the singing of the national anthem.

Rudi Buys, Dean of Student Affairs, said that the symbolic chain showed the UFS community’s aim to “join together as a country and show our commitment to our people” on the special day.

Mangaung Metropolitan Municipality Executive Mayor, Thabo Manyoni, together with Prof Jansen, welcomed UFS staff and students to the main festivities which centred around a coin-laying ceremony in front of the Main Building. All proceeds of the coin laying are to be contributed towards the NSH. More than R83 000 was raised through the coin-laying ceremony and donations, more than double the amount of 2012.

The jubilant crowd was edged on by OFM presenter, Johrné van Huyssteen, who offered to preside as master of ceremonies free of charge as part of his 67 minutes.

Manyoni stressed that Mandela Day is a celebration and should be regarded as a joyous occasion. He said that Madiba’s ability to take action and inspire change, is the foremost aspect of his legacy, one all South Africans should strive to emulate.

“We should all be the champions in the areas where we are. There can never be another Madiba, but we should all aim to be smaller, better Madibas,” he said.

Zelda la Grange emphasised the life-changing influence Madiba has had on her own life, as well as South Africa in general.

“Mandela Day is a call to action for individuals, for people everywhere, to take responsibility for changing the world into a better place, one small step at a time, just as Mr Mandela did. It is a day of service,” she said.

According to her, certain key characteristics are responsible for Madiba’s vast reverence throughout the world, principles everyone should try to emulate. She mentioned his principles, simplicity, honesty, integrity, discipline and respect for other people even when opinions differ, as the foremost of these qualities.

La Grange also stressed that the goodwill shown on Mandela Day should not be limited to one day in a year, but that we should all strive to live each day according to these principles.
