Navil Hill Planetarium
At the Naval Hill Planetarium, one of only two in the world that is located in a game reserve in the middle of a city, are from the left, front: Bishop Billyboy Ramahlele, Director of Community Engagement, Tony Horn, Dr Molapo Qhobela, Dorah Klaas from UFS Institutional Advancement, Motheo Leeuw, and Prof Matie Hoffman.

Just over 11 years ago, the University of the Free State (UFS), the Mangaung Metro Municipality, and the Department of Small Business Development, Tourism and Environmental Affairs (DESTEA) signed a Memorandum of Understanding that focused on the development and establishment of the Naval Hill Planetarium. In 2016, the partnership was extended to include the establishment of a facility for environmental education adjacent to the planetarium. Thus, the site on Naval Hill, Bloemfontein is now the Centre for Earth and Space.

Recently, colleagues from the UFS and DESTEA, as well as Free State tourism entrepreneurs, gathered at the planetarium and Boyden Observatory to discuss the next step in this partnership – a collaboration to bring astro-tourism to the Free State.

 

Astro-tourism facilities

Tourism Registrar at DESTEA, Motheo Leeuw, said in his welcome address that,in order to increase the number of visitors to the Free State, it is important to work together. “We are creating a new product, that of astro-tourism,” he stated, and requested the tour guides who attended the event to develop an innovative new product for their market.

Speaking on behalf of the UFS, Dr Molapo Qhobela, Vice-Rector: Institutional Change, Strategic Partnerships and Societal Impact, stated that astro-tourism holds enormous potential for this country. He said the UFS is excited to be a partner in this initiative.

Dr Qhobela said he believes the beauty of science can be used to promote astro-tourism. He echoed Leeuw’s sentiment, stating that it is only through partnerships that astro-tourism will become a reality. “If we want to drive astro-tourism, we need to find creative ways to connect with each other,” he stated.

“We must work together to make our home, Bloemfontein, a better place,” he said.

 

A taste of astro-tourism

About 30 delegates, including the UFS, DESTEA, military representatives, and tour guides from Bloemfontein and Clarence, gained first-hand experience of the potential of astro-tourism. They attended a full-dome pre-rendered astronomy show and a presentation on the night sky in the Naval Hill Planetarium, where images were projected onto the planetarium dome, resulting in an immersive experience of the wonder of the universe. The tour guides proceeded on a game drive in the Franklin Game Reserve on Naval Hill.

Later in the afternoon – after enjoying a sunset view of the environment at the Boyden Observatory – guests were introduced to the observatory, including its telescopes and the Astronomy Museum. Prof Matie Hoffman, Dr Mart-Mari Duvehage, and Dawid van Jaarsveldt from the Department of Physics at the UFS, were on hand to conduct the tour of the observatory, and Bishop Billyboy Ramahlele, Director of Community Engagement, hosted the guests.

Tony Horn, a tour guide from Bush Junkies Adventure Safaris – one of the guests at the event – is optimistic about the potential of this initiative. He said he will bring visitors to Boyden and the planetarium to experience the attractions.

 

The Two-Observatories Project

The Boyden Observatory and the Naval Hill Planetarium are known as the Two-Observatories Project, which will be the focus of astro-tourism in the Free State. Focus areas of the Two Observatories Project are science communication and education, research, astronomy heritage, and the environment. The project therefore has great potential to attract tourists.

According to Prof Hoffman, the two observatories work in synergy to educate and inform citizens about the natural sciences. They are also important for the display of and communication about South Africa’s astronomical heritage.

In addition to being an active optical research site, Boyden Observatory is ideal for public lectures and star-gazing events. Educational programmes, including observations with telescopes, are also presented at the observatory. An astronomy museum is a major attraction at Boyden.

The Naval Hill Planetarium, also a good venue for public lectures and concerts, offers planetarium shows, including full-dome films. The site also offers a large hall that is primarily used for environmental education. These facilities operate under the banner of the Free State Centre for Earth and Space.

UFS researchers are producing various flavour and fragrance compounds
2015-05-27

 

The minty-fresh smell after brushing your teeth, the buttery flavour on your popcorn and your vanilla-scented candles - these are mostly flavour and fragrance compounds produced synthetically in a laboratory and the result of many decades of research.

This research, in the end, is what will be important to reproduce these fragrances synthetically for use in the food and cosmetic industries.

Prof Martie Smit, Academic Head of the Department of Microbial, Biochemical and Food Biotechnology at the UFS, and her colleague Dr Dirk Opperman, currently have a team of postgraduate students working on the production of various flavour and fragrance compounds from cheap and abundantly available natural raw materials. 

Prof Smit explains that most of the flavours and fragrances that we smell every day, originally come from natural compounds produced mainly by plants.

“However, because these compounds are often produced in very low concentrations by plants, many of these compounds are today replaced with synthetically-manufactured versions. In recent times, there is an increasing negative view among consumers of such synthetic flavour and fragrance compounds.”

On the other hand, aroma chemicals produced by biotechnological methods, are defined as natural according to European Union and Food and Drug Administration (USA) legal definitions, provided that the raw materials used are of natural origin.  Additionally, the environmental impact and carbon footprint associated with biotech-produced aroma chemicals are often also smaller than those associated with synthetically-produced compounds or those extracted by traditional methods from agricultural sources.

During the last four years, the team investigated processes for rose fragrance, vanilla flavour, mint and spearmint flavours, as well as butter flavour. They are greatly encouraged by the fact that one of these processes is currently being commercialised by a small South African natural aroma chemicals company. Their research is funded by the Department of Science and Technology and the National Research Foundation through the South African Biocatalysis Initiative, the DST-NRF Centre of Excellence in Catalysis and the Technology Innovation Agency, while the UFS has also made a significant investment in this research.
