During the installation of the new computer and projector equipment at the Naval Hill Planetarium, were from the left: Dieter Schwab and Alex Reither from Sky-Skan, and Prof Matie Hoffman, Barry Crous (Instrumentation), and Pat van Heerden (Department of Physics) from the UFS.

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.

Kovsie trailblazing track runner sets South African 200 m record

Wayde van Niekerk became the only South African, and the fourth athlete in the world, to clock sub-20-seconds in a 200 m race on Tuesday 14 July 2015. With this winning time, he became the fourth member of the prestigious quartet, consisting of Michael Johnson, LaShawn Merritt, Isaac Makwala and himself.

The Kovsie gold medallist’s ground-breaking performance saw him beat world-class 200 m specialist and last year's Diamond League race winner, Alonso Edward of Panama. Van Niekerk crossed the finish line half a metre ahead of Edward, who was followed by Fujmitsu Kenji of Japan in the third place.

Van Niekerk's 19.94-time at the Diamond League meeting in Lucerne (Switzerland) set a national record, and improved on his personal best. In 2010, he claimed the World Junior Championship title in Moncton, Canada, by covering 200 m in 21.02 seconds.

Recently, he made history by defeating the London 2012 Olympic Games champion, Kirani James, of Grenada in the Caribbean.

On 4 July 2015, he surged 0.79 seconds ahead of Kirani in his number five lane, becoming the first African to cover 400m in less than 44 seconds. The Kovsie student won the race at 43.96, occupying 10th place on the International Association of Athletics Federations (IAAF) Diamond League all-time list.

Kovsies were still celebrating the gold medalist’s South African record-setting time of 44.24 on 13 June 2015 when he dominated the Diamond League meeting. At the previous race in New York, Van Niekerk improved on his own national record of 44.38. With an impressive dash to the finish line at that particular event, he surpassed Christopher Brown’s 400 m record.

In addition to the country’s record, Van Niekerk made his name as one of the continent’s record-breakers. On 7 June 2015, he broke the 1986 African 300 m record. Van Niekerk replaced Ivorian Gabriel Tiacoh’s best time of 31.74 with a 31.63 championship win at the Birmingham Diamond League meeting. Simultaneously, he bettered Morné Nagel’s 2006 South African national record.

Following his outstanding performance, he was positioned in 10th place on the world list in the men’s 300 m.
