The Naval Hill Planetarium at the Centre for Earth and Space on Naval Hill was inaugurated on 1 November 2013. It was the first digital planetarium in Africa south of the Sahara.

The Department of Physics at the University of the Free State (UFS) is responsible for the Naval Hill Planetarium (formerly the Lamont-Hussey Observatory). The department uses the planetarium to educate and inform citizens about the natural sciences. The planetarium, together with the Boyden Observatory, is also important for the display and communication of South Africa’s astronomical heritage.

The planetarium system was recently upgraded in a project that cost R6 million. According to Prof Matie Hoffman from the Department of Physics, it was time to upgrade the computers and graphic cards, and to replace the lamp projectors with laser projectors.

Funding for the state-of-the-art equipment came from the Faculty of Natural and Agricultural Sciences and the Information and Communication Technology Services (ICT Services) at the university. Businesses in Bloemfontein – First Technology and Raubex Construction – also contributed to the project.

Presenting programmes more often

Planetarium specialists Dieter Schwab and Alex Reither from Sky-Skan Europe, based in Germany, installed the new equipment over a period of two weeks.

Prof Hoffman says the new equipment will enhance the experience of people visiting the planetarium for a close encounter with the wonders of the universe to deepen their appreciation of science and astronomy.

“Besides a clearer image with better colour, the new projectors will also be more economical to operate. This means we will be able to offer programmes at the planetarium more often,” he says.

The upgrades also include new software. Prof Hoffman explains that the software will enable more sophisticated presentations and open the door to the use of the planetarium for higher level visualisation of scientific data where any large data sets with many variables are involved, such as climate science, astrophysics, and cosmology.

Offering an incredible experience

After completion of the installation, a period of two weeks will be spent on training to master the use of the new equipment and the software. The public can expect the first show with the new equipment at the end of June.

“I am most looking forward to the planetarium creating an incredible experience – better than in the past – for the public and increasing everyone's admiration and understanding of the universe. I also believe the planetarium is an excellent facility to improve students' skills in science communication, and it provides these students the opportunity to share their knowledge with the public,” concludes Prof Hoffman.

Johann swims his way to Olympics

In the past couple of months, Johann van Heerden has been swimming his way to the Paralympic Games, and is still preparing as if he will be going to Rio de Janeiro.

The Kovsie swimmer, who will know whether he has been included in the Paralympic team in July 2016, feels his training is progressing well. The Olympics will be held in Brazil from 7 to 18 September 2016. If all goes well, this could be the first of several Olympics for the 20-year-old second-year Education student from the University of the Free State (UFS).

Dream year for Education student

Van Heerden (cerebral palsy), whose hero is the former Paralympic superstar Natalie du Toit, has had huge successes in the run-up to the 2016 Olympics. Among others, he was named the best senior swimmer at the Nedbank National Championships for the Physically Disabled in Bloemfontein in March 2016. At the South African Senior Championships in Durban in April 2016, he qualified for the Olympics in the 100 m breast-stroke with an A-qualifying time, and in the 50 m and 100 m freestyle with B-qualifying times.

Only three male swimmers to Olympics

However, he has to wait until the announcement of the South African Paralympic team, since only three male and three female swimmers will be selected. He will not be competing in another major event before the Olympics. “My short-term goal is to compete in this year’s Games, and, in the long term, I would like to reach even greater heights at the 2020 Games,” he said. Du Toit is an inspiration to him because “she was hard-working, and she had a lot of drive”.

Other students from CUADS also excel

At the above-mentioned National Championships, Van Heerden won a total of five gold medals (200 m medley, 100 m breaststroke, 50 m freestyle, 50 m breaststroke, and 200 m breaststroke) and one silver medal (100 m freestyle). Other students from the Center for Universal Access and Disability Support at the UFS also excelled.

Dineo Mokhosoa (cerebral palsy) won three gold medals (long jump, shot-put, and discus), while the athlete Louzanne Coetzee (blind) shattered the world record in the 5 000 m, as well as the Africa record in the 1 500 m. Juanré Jenkinson (cerebral palsy) won two silver medals (discus and shot-put) while Danie Breitenbach (blind) won two gold medals (800 m and 1500 m).
