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.

Full week of graduation ceremonies at UFS in April

2015-04-10

Autumn always sees the UFS’s first graduation ceremony of the year on the Bloemfontein Campus.

From 14 – 17 April 2015, graduates will once again be rewarded for their hard work while top speakers will address them in the Callie Human Centre. There will be a ceremony at 09:00 and at 14:30 each day on all four days of the graduation.

The programme for the 2015 April Graduation is as follows:

Tuesday 14 April 2015:

Professor Himla Soodyall will be the speaker at both ceremonies on this day. Prof Soodyall is a Medical Scientist for the South African Institute for Medical Research. She is also a Principal Medical Scientist for the National Health Laboratory Service, and a Director for the Human Genome Diversity and Disease Research Unit at the University of Witwatersrand.

During the first ceremony of the day at 09:00, all diplomas/certificates and B degrees in the Faculty of Natural and Agricultural Sciences will be awarded. Only Honours degrees in the Faculty of Natural and Agricultural Sciences will be awarded at the 14:30 ceremony.

Wednesday 15 April 2015:

Wednesday will see Ndumiso Hadebe take the stage to address graduates at both ceremonies.

At the age of 23, Hadebe is the Founder and Managing Director of Master Frontiers Consulting, a firm that capacitates leaders and managers to achieve business goals through their people. He worked previously as a Researcher at Shanduka Black Umbrellas, a flagship enterprise and supplier development programme of the Shanduka Foundation.

He has been received numerous awards for excellence in leadership, such as the Sedibeng District Municipal Mayor’s Award for Service and Leadership. He is a Brand South Africa Ambassador and Read Educational Trust Ambassador.

All diplomas/certificates, B and Honours degrees in the Faculty of Economic and Management Sciences, except B Com degrees, will be awarded during the morning ceremony at 09:00. Later, at the 14:30 ceremony, only B Com degrees in the Faculty of Economic and Management Sciences will be awarded.

Thursday 16 April 2015:

Multiple award winning South African TV presenter, Leanne Manas, will be the speaker at both Thursday ceremonies.

Manas has graced our screens for over a decade. Not many broadcasters can boast having had live TV experience, 5 days a week for 12 years. She is currently the anchor of SABC 2’s flagship breakfast programme, Morning Live. Leanne is a qualified Speech and Drama teacher. having studied at London Trinity College. She also has an Honours degree in English.
Diplomas/certificates up to and including Honours degrees in the Faculty of the Humanities, Social Sciences, and Communication Sciences will be awarded during the ceremony at 09:00. The 14:30 ceremony will have diplomas/certificates up to and including Honours degrees in the Faculty of the Humanities’ other qualifications except for Social Sciences and Communication Sciences.

Friday 17 April 2015:

Dr Maria Phalime will be the speaker at both ceremonies on Friday.

Phalime is a medical doctor and award-winning author. She practiced for a brief period as a general practitioner in South Africa and the United Kingdom, before leaving medical practice to pursue non-clinical interests. She has worked in trade and investment promotion, and has undertaken research and consulting in the areas of economic development and business facilitation.

Diplomas/certificates up to and including Honours degrees in the Faculty of Education (CE, NPDE and ACE excluded) will be awarded during the ceremony at 09:00. Diplomas/certificates up to and including Honours degrees in the Faculties of Health Sciences, Law, and Theology will be awarded at the 14:30 ceremony.
