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 institute set to contribute to transformation in South Africa

Today (Thursday, 27 January 2011), almost three years after the Reitz affair, the University of the Free State (UFS) is launching its International Institute for Studies in Race, Reconciliation and Social Justice. This international institute will be inaugurated by Archbishop Emeritus Desmond Tutu, Nobel Peace Prize Laureate and Chairperson of the former Truth and Reconciliation Commission, who received an honorary doctorate in Theology from the university earlier today.

According to Mr John Samuel, Interim Director of the institute and former Chief Executive Officer of the Nelson Mandela Foundation, the institute seeks to establish itself as a premier international site for research on race, reconciliation and social justice.

“It is encouraging to see the UFS bringing to the fore such an initiative, which combines a study in race, reconciliation and social justice, all of which are indispensible elements in the process of rebuilding our nation,” said the Deputy President of South Africa, Mr Kgalema Motlanthe, in his message of congratulations to the university.

“I am confident that on the strength of its stature, coupled with its eminent experience as an academic institution, the UFS will further assist our country advance towards a united, non-racial, non-sexism, just and prosperous future.

“I wish the institute well in its arduous but noble task of contributing to the building of a better human society,” he said.

Prof. Jonathan Jansen, Vice-Chancellor and Rector, stated during his official inauguration in 2009 that the university would be an example of a place where reconciliation, forgiveness and social justice would not only be studied, but where it would also be applied in practice. “Students and scholars from across the world will come to the UFS to study the theory and practice about the building of societies across the boundaries of race, as well as religion, gender, disabilities and national origin,” Prof. Jansen said.

The institute is a critical space where engaged scholarship, public discussion, community engagement and teaching are innovatively integrated towards exploring and finding solutions to the complex and challenging work of social transformation in South Africa.

The institute furthermore works towards the realisation of its mission through a multiplicity of approaches and methods, informed by the notion that deep and complex social challenges require courageous and challenging scholarship, supported by innovative organisational forms and institutional arrangements.

Working from the inside to the outside, the institute will firstly serve the needs of the university, its staff and students. Through its research, the institute will endeavour to understand the challenges facing the UFS better, as well as how to address these challenges. For this reason, the concept of the UFS as a “live laboratory” and the use of evidence-based practice remain important for the university.

The institute will also reach out and empower its stakeholder communities through research and ongoing involvement on issues of race, reconciliation and social justice. Furthermore the institution expects to contribute to the creation of national and international networks and dialogue platforms pertaining to race, reconciliation and social justice.

For the first five years, the themes of 1) Values, Faith and Social Justice; 2) Development and Social Cohesion; 3) Teaching and Learning for Social Justice; and 4) Provincial, National, Global Perspectives and Leadership will direct the institute’s work.

The UFS will make a substantial contribution to the pursuit of reconciliation, greater social cohesion and equity in South Africa. The university is thus prepared to continue to engage the difficult, practical and trying work of building a strong, quality institution as it promotes racial healing and addresses the structural imbalances of the past. It is at this nexus that the institute commits to enabling change at the university as well contributing to transformation in South Africa.
