In his book, The World is Flat, Thomas Friedman mentions how at first countries, then companies, and eventually communities went global. In true flat-world fashion, a combined team of the University of the Free State (UFS) and the Astronomical Society of South Africa – led by Prof Matie Hoffman, Associate Professor in the Department of Physics – participated in a once-in-a-lifetime event with their counterparts from the Ellinogermaniki Agogi School and the Skinakas Observatory in Greece.

On 21 December 2020, Earth was treated to the Jupiter-Saturn conjunction, when the two planets were only 0.1 degrees apart in the sky. Although conjunctions are regular phenomena, NASA mentions that the great conjunction of Jupiter and Saturn in 2020 was the closest since 1623 and the closest observable since 1226! A pinkie finger at arm’s length could cover both planets – although they were still millions of kilometres apart in space.

Planning started months ahead of the event, with the Ellinogermaniki Agogi Observatory in Greece and the Boyden Observatory in Bloemfontein chosen as the two selected vantage points. From both the Southern and Northern Hemisphere, the conjunction would be broadcast live on YouTube. As with any other technical project on an international scale, challenges arose. For example, in the Northern Hemisphere, it was already dark at 17:45 while the South African astronomers were still basking in sunlight until after 19:00. The conjunction would only be visible from South Africa after 19:30, almost two hours after it would be visible in Athens. The time was well used, with the event including a word of welcome by the Consul General of Greece in South Africa, Ioannis Chatzantonakis, presentations on Saturn and Jupiter, as well as a virtual tour of the Boyden Observatory, emphasising its connection with Greece through its first Director, Stefanos Paraskevopoulos. 

On Saturday, 19 December, the teams ‘gathered’ on opposite sides of planet Earth to do a dry run. One could sense the urgency and tension as both teams realised that they would have a huge captive audience on YouTube, and plans had to be made in case of connectivity challenges and if the weather did not allow the conjunction. As preparations progressed, Prof Hoffman was talking to his Greek counterparts and was simultaneously walking around with his laptop to share the landscape and activities via his webcam with colleagues in Greece. 

Monday 21 December 2020 – the weather prediction was correct. Clouds covered the Free State sky and scattered raindrops started to fall. Revert to Plan B. A recording made on Saturday evening was shared via the YouTube link, while a live feed of the conjunction from elsewhere in South Africa was arranged. From both sides of the world, information was shared about the history of the venues, as well as the marvel of what was happening in space. Fortunately, expert planetary photographer Clyde Foster was able to share a live feed just after 19:30 from the observatory at his home in Centurion, Gauteng. Those attending the event where visuals and speakers were together on one screen – yet thousands of kilometres apart – watching an event in outer space, will indeed agree with Thomas Friedman: the world is flat. The live-stream event of the conjunction was a catalyst that will result in continued collaboration between the UFS and colleagues in Greece in the field of astronomy. 

By the time of this writing, the livestream has reached more than 50 000 people.

The University of the Free State (UFS) joined people around the globe in celebration of the fourth annual Nelson Mandela Day. Long-time Madiba confidant, Zelda la Grange, delivered the main address, inspiring the crowd with anecdotes gleaned from her intimate knowledge of the former president.

La Grange felt that the UFS as an institution can contribute greatly towards the upliftment of South African society.

“Your university has become what we hope for in South Africa – a transformed society whose purpose serves the greater good of humanity. Embrace and nurture what you have here under the leadership of Prof Jansen and his team. And influence society consciously, every day, in the same way as Madiba did for every day of the 67 years of his activism, and beyond.”

As UFS Vice-Chancellor and Rector, Prof Jonathan Jansen, aptly put it, the Kovsie celebrations aim to give thanks to Madiba as a ‘model of humanity’ and for what he has done for all South Africans.

Prof Jansen stressed that the importance of Mandela Day cannot be overstated.

"I think it is incredibly important because the real legacy of Nelson Mandela is that of a man who gave everything he had for the struggle to gain our freedom, our democracy and that we can get along as just human beings and not as a skin colour, a religion or as strangers," he said.

Events began with a clean-up operation by UFS volunteers, Zelda la Grange and the Bikers for Mandela Day, the Mangaung Metropolitan Municipality and other sponsors. The team cleaned areas in Heidedal and Manguang before returning to the UFS Bloemfontein Campus.

Kicking off the campus section of the programme, UFS staff and students formed a ‘human chain’ on the Red Square as part of a wider initiative which was the brainchild of Archbishop Emeritus Desmond Tutu – who was the main attraction of the 2012 Mandela Day activities at Kovsies.

The assembled ‘chain’ recited the UFS Mandela Day pledge, whilst snaking around the Red Square and the gardens surrounding the Main Building, before offering interfaith prayers to Madiba in honour of the 67 minutes of selflessness epitomised by Nelson Mandela Day.

To conclude the first part of the celebrations, the No Student Hungry campaign’s patrons, Mrs Grace Jansen and Dr Carin Buys, released symbolic doves and joined the chain in the singing of the national anthem.

Rudi Buys, Dean of Student Affairs, said that the symbolic chain showed the UFS community’s aim to “join together as a country and show our commitment to our people” on the special day.

Mangaung Metropolitan Municipality Executive Mayor, Thabo Manyoni, together with Prof Jansen, welcomed UFS staff and students to the main festivities which centred around a coin-laying ceremony in front of the Main Building. All proceeds of the coin laying are to be contributed towards the NSH. More than R83 000 was raised through the coin-laying ceremony and donations, more than double the amount of 2012.

The jubilant crowd was edged on by OFM presenter, Johrné van Huyssteen, who offered to preside as master of ceremonies free of charge as part of his 67 minutes.

Manyoni stressed that Mandela Day is a celebration and should be regarded as a joyous occasion. He said that Madiba’s ability to take action and inspire change, is the foremost aspect of his legacy, one all South Africans should strive to emulate.

“We should all be the champions in the areas where we are. There can never be another Madiba, but we should all aim to be smaller, better Madibas,” he said.

Zelda la Grange emphasised the life-changing influence Madiba has had on her own life, as well as South Africa in general.

“Mandela Day is a call to action for individuals, for people everywhere, to take responsibility for changing the world into a better place, one small step at a time, just as Mr Mandela did. It is a day of service,” she said.

According to her, certain key characteristics are responsible for Madiba’s vast reverence throughout the world, principles everyone should try to emulate. She mentioned his principles, simplicity, honesty, integrity, discipline and respect for other people even when opinions differ, as the foremost of these qualities.

La Grange also stressed that the goodwill shown on Mandela Day should not be limited to one day in a year, but that we should all strive to live each day according to these principles.
