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.

Cohesions and Disruptions Forum
2014-07-15

 
The Institute for Reconciliation and Social Justice at the UFS and the Johannes Stegmann Art Gallery, in partnership with the Vryfees, co-presented an artist and academic forum on 18 July 2014.

The forum, ‘Cohesions and Disruptions: Art as a Key to Transformation’, was aptly timed to coincide with Mandela Day. This event formed part of the transformation strategy of the Vryfees arts festival, aiming to support more diversity and cross-cultural, contemporary art programmes.

“Cohesions and Disruptions is part of the new Program for Innovation in Artform Development (PIKO/PIAD),” said Adri Herbert, Director of the Vryfees. “This includes both the cross-cultural OPENLab 2014, a new Australian/South African laboratory for early and mid-career South African artists, and a partnership with the Australian based SituateArt in Festivals initiative, managed by Salamanca Arts Centre in Hobart, Tasmania.”

The forum’s keynote speaker was Lee-Ann Tjunypa Buckskin. She is a Narungga, Wirangu, Wotjobaluk woman from South Australia and Victoria respectively. She is well known throughout the Aboriginal and Torres Strait Islands and broader arts communities. Buckskin’s presentation was titled ‘Building Young Indigenous People’s Lives through Art and Culture in Remote Central Australia.’

Buckskin spoke broadly about her involvement with youngsters – often poverty stricken and sniffing petrol – in remote areas of Australia. She explained how the arts have given the youth a chance at rehabilitation and hope for the future.

After her presentation, she was joined by Dr Willy Nel, lecturer at the UFS School of Education Studies. Dr Nel completed his PhD among the Khomani San in the Kalahari. 

Other forum speakers who presented their work included:
Dr Mari Velonaki, Director of the Centre for Social Robotics at the National Institute for Experimental Art at the University of New South Wales, Sydney;
Dr Nigel Helyer of Sonic Objects; Sonic Architecture, Sydney;
Bec Dean, Curator at Performance Space, Sydney;
Jesse Olivieri, co-founder of Parachutes for Ladies in Sydney; and
Cigdem Aydemir, Vryfees visual artist for 2014.

“Given the histories and present experiences of human rights violations and racial discrimination that indigenous people in Australia and South Africa are subjected to, we are particularly honoured to have Lee-Ann (Buckskin) as a guest speaker,” said Prof Andre Keet, Director of the UFS Institute for Reconciliation and Social Justice.
