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.

State of our campuses: Impact of non-completion of the 2016 academic year on UFS students

2016-10-08

Dear Parents/Guardians and Students,

Impact of non-completion of the 2016 academic year

The University of the Free State (UFS) reiterates its support and commitment to the cause of free higher education. We have stated our position in all the available spaces. We want to work with UFS students to put pressure on the government to commit itself to accept the many suggestions put forward to make free education possible within a negotiated timeframe.

We are also seriously committed to our responsibility of providing education to all students enrolled at the university. We are doing our outmost to ensure that we can resume academic activities next week.

Description: " Academic non-completion 2016 Tags: " Academic non-completion 2016

We want to bring to your attention what will happen to individual students if the UFS cannot resume classes fully on Monday 10 October 2016.

Currently we have extended the academic year by one week. Some faculties are working on Saturdays and Sundays, starting earlier and finishing later to complete the material that needs to be taught and the practical work that students need to do to be able to write exams.

In the three biggest faculties at the university: Education, the Humanities, and Natural Sciences, this is what will happen:

Education will fail to graduate 1 193 students
Humanities will fail to graduate 1 125 students
Natural and Agricultural Sciences will fail to graduate 1 390 students

In the professional faculties: Economic and Management Sciences, Health Sciences, and Law, this will happen:

Economic and Management Sciences will fail to graduate 997 students
Health Sciences will fail to graduate 633 students
Law will fail to graduate 619 students

In total, approximately 6 000 students will not receive complete transcripts of their degrees and the certificates for their qualifications.

The university currently has 3 238 students on NSFAS bursaries. None of these students will be able to apply for bursaries for the lost year. They will be regarded as having failed or not completed their courses. They will not only miss this year, but the opportunity of studying in the future.

These students come from families to which their success in higher education was supposed to mean a change in the future of the entire family. Some parents/guardians hold more than one job to be able to pay tuition fees.

In not allowing the year to continue and students to finish, we are throwing away the efforts that entire families of poor people have made for four or five years to put their children through university. The promise of free education for future generations means nothing to these families who are poor in the present.

In terms of the academic calendar, it is a false argument to say that universities will be able to enrol first-years, because what 2016 students will miss, is the second semester.

We do not have the capacity to teach double the number of students in the second semester. This also misses the point that those students who were completing modules in order to graduate, will waste an entire year (assuming they have funding) to complete their degrees. This argument does not see the knock-on effect that students, not promoting in modules from first to second and second to third year, etc., will have. Finally, this also misses the point of what will happen to students who have to repeat first-semester modules.

In terms of academic staff, students are discounting the willingness of academic staff to teach double or to have the academic year extended by approximately six weeks between teaching and examinations. The same can be said for all the administrative and support staff required for running the university.

In our case, all the students in the University Preparation Programme (UPP) on the South Campus in Bloemfontein will be stuck without being able to move into mainstream modules, preventing a new intake of UPP students for 2017. These are the poorest and most disadvantaged students at the UFS.

It is absolutely necessary to find a means of protest and political action that will not jeopardise the future of current students and the country’s desperate need for critical skills. The interdict against violent protest secured by the UFS is still in force. The police will intervene if the interdict is not respected and the UFS will have no control over police actions.

We trust that parents/guardians and students understand the implications of the situation.

Kind regards,

Prof Nicky Morgan
Acting Rector
University of the Free State
