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.

ANC is not a party of the people - Mbeki
2010-08-30

 

 

“The unions in this country do not understand the political economy of South Africa. They think that the ANC is the party of the people. The ANC is the party of the black middle class. The fact that the masses vote for it does not mean they control it. The policies of the ANC favour the black middle class and the established businesses. They do not favour the working class.”

This was said by renowned economic and political commentator Mr Moeletsi Mbeki, brother of former president Thabo Mbeki, during a guest lecture he recently presented to Economics students of the University of the Free State (UFS) in Bloemfontein.

“You just have to look at the types of houses that the ANC government builds for ordinary South Africans,” he said.

“If you had a party that was a pro-working class party it would not have built these so-called RDP houses that are being built by the ANC government. The unions have all along been under the illusion that the ANC is the government of the working class and (Zwelinzima) Vavi and them are now beginning to realise that this is not the case.

“The public-sector workers are in a special dilemma. They think the ANC is their ally but at the same time they feel they are not getting any benefits out of this alliance. Therefore you are beginning to get a very acrimonious environment emerging between the public-sector unions and the government.”

Regarding the current issue of the Protection of Information Bill and the proposed media tribunal that have brought the media and the government onto a collision course, Mbeki said the ANC government was trying to muzzle the media because it wanted to safeguard corruption within government.

“The question of freedom of information is very closely linked to the rise in corruption in the government,” he said.

“What the politicians are doing is that they are trying to hide that corruption. The media in this country have been playing a very critical role in exposing cases of corruption. That is why Vavi now has bodyguards.”

He said he recently met Vavi, the General Secretary of Cosatu, surrounded by four bodyguards. He said Vavi told him that he was getting death threats because he was opposing corruption in government.

Mbeki said the economic policies of South Africa were the “worst in the world” because they benefited people who were already rich and militated against the emergence of entrepreneurs.

“In fact, one of the serious downsides of Black Economic Empowerment (BEE) is that it takes people who should normally be entrepreneurs and who should be creating new companies and new jobs, out of that space and just makes them wealthy. BEE has been a disaster because it created this massive economic inequality; it created this class of idle rich who have tons of money but do nothing,” he added.

He said the under-investment in the economy was having dire consequences in terms of unemployment and poverty. He said this, coupled with the growth of consumption that Black Nationalism was driving, was actually driving down the ability of the economy to absorb labour.

“What really lies at the bottom of our economic problems in South Africa is that we have too much of a one-party dominance of our political system. We need more competition in our political system and until we realise the policies of the ANC are not going to change,” he said.

Mbeki’s guest lecture was on the topic: Architects of Poverty: Why African capitalism needs changing.
