UFS Solar car
Team UFS entered the Sasol Solar Challenge for the very first time this year, competing with seven other teams and showcasing their technological input and innovation.

Excitement. Nervousness. A thousand thoughts going through our minds, but primarily “Are we really ready for the challenges that lie ahead?” and “What did we get ourselves into?” In the moments leading up to this year’s Sasol Solar Challenge, these were the thoughts and emotions of Team UFS, who entered their solar car, Lengau.

“But I had confidence in the team,” says Dr Hendrik van Heerden from the UFS Department of Physics at the University of the Free State (UFS) and project manager of Team UFS who entered the challenge for the very first time this year.

Testing perseverance

Entering the Sasol Solar Challenge – a biennial competition that has been running since 2008 – Team UFS competed against seven other teams (representing local and international universities, high schools, and engineering teams), sharing the public roads of South Africa with trucks and regular traffic, sometimes experiencing steep mountain climbs, testing not only their technological input and innovation, but also their perseverance over an eight-day period. 

“One of our main challenges was the long time on the road, to which the heavy weight of the solar car, efficiency of the solar panels, and the effective charging of the battery contributed,” says Dr Van Heerden, stating that these problems were difficult to tackle with the small budget they had. “We, however, stayed positive and was determined to pull through.” 

“We were also open for learning from the other teams, the scrutineers, and observers regarding the mechanical, electrical, and body of competing solar cars. Thus, building knowledge and collaborating is a success we celebrate,” he adds.

In the end it paid off, as Team UFS completed the race, covering a distance of more than 500 km and ending in seventh place overall. The team that finished with the greatest distance covered within the allotted time won the challenge, in this instance the Brunel Solar Team, covering 4 228,2 km.

Dr Van Heerden believes that they did exceptionally well for a debut team, proving themselves against the best. “I am of the opinion that this challenge made us stronger and gave each of us a new perspective on how we should approach life,” he adds.

“As we are all enthusiastic about science and engineering, this challenge inspired us to build towards a future where renewable energy could be an important source of energy in South Africa.”

Learning the ropes

The teams left Carnival City in Johannesburg on 9 September 2022 and arrived at the finish line at the V&A Waterfront in Cape Town on Friday 16 September 2022.

Talking about the next race, Dr Van Heerden says he wants to build a better, more effective solar car. “We strive to continuously improve the design, technology, and science going into our car,” he says. 

“For this challenge, we were interested in learning about the mechanical, electrical, and overall body of a solar car. Hence, our solar vehicle was designed well enough to participate and reliable enough to succeed.”

According to him, their focus will shift to competing against the other teams for the next Sasol Solar Challenge. “We will also be more prepared, since we now know what to expect from the challenge. It was our first time participating in the Sasol Solar Challenge, and we’ve learnt so much from the past two weeks – we will carry that forward to the next challenge.

The University of the Free State (UFS) hosted NASA Deep Space engineer Christopher Jacobs on 27 March 2017 at the Bloemfontein Campus. The engagement was hosted by Prof Matie Hoffman of the Department of Physics and the Department of Institutional Advancement, in collaboration with the US Consulate General in Johannesburg.

Jacobs is stationed at NASA’s Jet Propulsion Laboratory (JPL) at the California Institute of Technology and has served as the Reference Frame Calibration task manager for 25 years. In this role he has been responsible for delivering the reference frames used to navigate NASA missions such as the Mars Science Laboratory to planetary targets.

His visit to the UFS included a presentation to the Department of Astrophysics at the Faculty of Natural and Agricultural Sciences and at the Naval Hill Planetarium in Bloemfontein where he spoke on Stellar GPS: Navigating the Solar System. He also spoke about the latest research and developments at NASA in Astrometry. The visit will establish and develop shared interests and possible collaboration with UFS and other institutions of interest in the country. “South Africa, because of its well-placed geographic location in the southern hemisphere, holds a lot of answers to astronomy,” Jacobs said.

He has an active interest in professional and public education, and outreach, having given public lectures around the world. “Astronomy brings people together and is a point of common interest that is key in solving environmental and geographical challenges such as climate change, therefore global cooperation is important,” he said.

Prof Hoffman welcomed the initiative by the US Consulate and the possible outcomes of joint efforts to position the UFS as a key partner in South Africa on NASA’s astronomy projects. In the coming weeks Jacobs will speak at high schools in Gauteng including the Mae Jemison US Science Reading Room in Mamelodi, Pretoria, a centre that is focused on promoting science education.
