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.

Deputy Minister leads a space science outreach programme in Bloemfontein
2014-02-28

The Deputy Minister of Science and Technology, Michael Masutha and Mandla Maseko– the first black South African expected to go into space in 2015 – will participate in a Space Science Outreach Programme at the University of the Free State on Saturday 1 March 2014.

The event, taking place at the Bloemfontein Campus, is part of an outreach programme to raise awareness about South Africa’s advances in space science and technology and its benefits to society.

Mr Maseko will share his exciting experiences in the Axe Apollo Space Academy competition, a challenging event that included skydiving, aptitude tests and building and launching a rocket with about 600 learners from the surrounding areas. The 25-year-old from Mabopane near Pretoria will become the first black astronaut when he goes into space on the Lynx Mark II Shuttle, next year.

The outreach event will include activities such as telescope making and rocket launching. Workshops demonstrating the benefits of space science in areas such as earth observations, scientific research and development and human capital development, will also be conducted.

Among others, the open day will feature exhibitions such as the project to build the world’s largest telescope, the Square Kilometre Array and the recent launch into space of the country’s micro-satellite – ZACUBE1 built by post-graduate students at the Cape Peninsula University of Technology (CPUT).

Other exhibitors will include the Hartebeesthoek Radio Astronomy Observatory (HartRAO), the Agricultural Research Council, Denel Dynamics, the South African National Space Agency (SANSA) and the South African Weather Services (SAWS).

Officials from the provincial Department of Basic Education are also expected to attend.

Journalists are invited to the outreach

Venue: Economics Building, University of the Free State
