Space and satellites: awareness and observations

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.

You have the knowledge, which is a big resource, and should use it to the benefit of South Africa. This was the overwhelming message to graduates obtaining their master’s and doctoral degrees at the University of the Free State (UFS).

Their responsibility was emphasised by the likes of Justice Mahube Molemela during the ceremonies in the Callie Human Centre at the Bloemfontein Campus on 26 June 2017. Justice Molemela, Judge President of the Free State Division of the High Court and Acting Justice of the Supreme Court of South Africa, was the guest speaker at the morning and afternoon ceremonies.

The UFS conferred 388 master’s and 72 doctoral degrees on the final day of its mid-year graduation ceremonies, which was the biggest set of ceremonies in the university’s history. The doctorates came from the Faculty of Natural and Agricultural Sciences (30), Faculty of the Humanities (15), Faculty of Economic and Management Sciences (9), Faculty of Education (8), Faculty of Health Sciences (5), and Faculty of Theology (5). A total of 5 258 degrees were conferred over six days from 19 to 26 June 2017.

Future dependant on youth
Justice Molemela said the master’s and doctoral graduates have the skills to make a difference. “The future of a nation is largely dependent on its youth playing a meaningful role in creating a strong economy, culminating in a good standard of living for everyone.”

She said they should plough back into their communities and give opportunities to others. “I am certain that if each one of you thinks innovatively in your respective fields, you will find solutions which will eradicate poverty, improve service delivery, and hence our education will advance gender equity, and promote public participation.”

Dr Khotso Mokhele, UFS Chancellor, said these graduates have every reason to hold their heads high, their shoulders square, and walk with a bit of an attitude, as they have distinguished themselves.

Generation of new knowledge
According to Prof Francis Petersen, Rector and Vice-Chancellor, the UFS strives to be a university that is research led. “For me, one of the important aspects about universities which set them apart from other training and vocational institutions is the generation of new knowledge,” he said at a lunch function for PhD graduates on 26 June 2017. He feels it is critically important for them to make a contribution to the country.

Dipiloane Phutsisi, Principal and Chief Executive Officer of the Motheo TVET College in the Free State, also emphasised this. Phutsisi was the guest speaker on 23 June 2017. “Your courage and eagerness to face the future and tell the truth in the midst of this confusion, is highly desired by South Africans.”

Justice Ian van der Merwe, Judge of Appeal at the Supreme Court of Appeal and former Chair of the UFS Council, was the guest speaker at the ceremonies on 22 June 2017. He encouraged graduates from a chapter in the book War and Peace by Leo Tolstoy.

“There is no greatness where there is not simplicity, goodness, and truth (according to Tolstoy). Or maybe more modernly translated: There is no greatness where simplicity, goodness, and truth are absent.”
