Mars
One of the first colour photographs of Mars, taken through the lens of the Lamont-Hussey telescope in 1939. The telescope was restored and is currently on display at the Naval Hill Planetarium.

In 2018 the University of the Free State (UFS) launched the historic 27-inch Lamont-Hussey Refractor telescope exhibit together with the completed observation platform and a garden in front of the Naval Hill Planetarium in Bloemfontein.

The re-installation of the telescope as a static outdoor exhibition at Naval Hill is now complete. The project started several years ago after the recovery of abandoned parts of the old telescope. What followed was a story of trial, patience, careful planning and a lot of hard work.

 

Taking it apart

According to Dawid van Jaarsveld from the UFS Department of Physics, the mounting and tube of the Lamont telescope has returned to its home, the Lamont-Hussey Observatory, for display. The telescope had 47 years of service and years of abandonment in the veld after it was taken apart in 1975.

Its former telescope dome now hosts the Naval Hill Planetarium, the first digital planetarium in Sub-Saharan Africa.

The telescope was taken apart after the observatory was closed in 1974. It was dismantled and the optics were sent back to the University of Michigan with the largest pieces “left for dead in the veld” on the grounds of the Ehrlichpark Fire Station.

According to Dr Hendrik van Heerden from the UFS Department of Physics, who assisted in the technical side of re-installing the telescope, the larger pieces were recovered by Braam van Zyl and subsequently moved into the museum hanger of the Bloemfontein Fire Brigade where they stayed for many years.

 

Contribution to science

The University of Michigan in the US built the Lamont-Hussey Observatory between 1926 and 1928 in Bloemfontein for the study of double stars. The telescope had great historic significance and was used by professional astronomer RA Rossiter from Michigan, who set the record for discovering and measuring more than 5 000 double stars. The planetarium also measured the most double stars in the world, more than 7 000.

Van Jaarsveld describes a double star – also known as a binary star system – as two stars orbiting around one another. Studies of double stars enable researchers to determine the mass of stars.

Earl Slipher used the telescope to take one of the very first colour photographs of Mars in 1939. Slipher took 60 000 photos of Mars in 1939, 1954 and 1956 with the telescope. He was the world expert on the planet at the time. The camera Slipher used is displayed in the Boyden Observatory museum just outside Bloemfontein.

 

Putting it together

Van Heerden continues: “In early 2017 the components [of the telescope] were relocated to Dukoc Manufacturing in Bloemfontein for cleaning, treatment and painting. It took a while, as the missing components had to be manufactured before the final painting could be completed. The missing pieces were made with the help of the original blueprints of the telescope, provided by Prof Patrick Seitzer of the University of Michigan.

“These blueprints, along with measurements taken from the cleaned parts at Dukoc Manufacturing were used by Barend Crous, UFS Head of Instrumentation, to develop and manufacture the missing parts. These include the polar axis (solid steel axle over 3 m long and weighing more than one ton), axis-bearing caps (cast-iron pieces weighing more than 100 kg and 200 kg respectively) and telescope position wheels and gear works. After the required components were manufactured and refurbished, they were relocated to the Naval Hill Planetarium for the launch ceremony which was held on 5 June 2018.

“Planning of the installation of the telescope thereafter started in earnest. The jigsaw had to be put together again. The sheer size of the parts required some heavy equipment during the installation. With hard work, good coordination and a bit of luck, a team consisting of myself as project coordinator and consultant, Barend Crous, site engineer; Innes Basson, supervisor; Denver de Koker, handyman; and Wikus Storm, welder, got the job done,” Dr Van Heerden said.

 

Information sessions

Astronomy enthusiasts, tourists, school groups and other members of the public can now visit the Lamont-Hussey telescope with it finally back home after many years of neglect and abandonment in the veld. It can again hold itself high, looking at the stars.

The official opening of the telescope will take place on 26 April 2019 and Prof Seitzer from the University of Michigan will attend the opening event.

The refurbishment of the old telescope and the establishment of the new garden and observing platform were made possible by a R1 million donation by ArcelorMittal.

School of Medicine not closing
2009-10-22

There is no immediate threat that the University of the Free State’s (UFS) School of Medicine will be closing.

This was confirmed by Prof. Gert van Zyl, Head of the UFS’s School of Medicine and acting Dean of the Faculty of Health Science, following media reports that Prof. Andries Stulting has indicated in a meeting with other medical schools and parliamentary standing committee members that the School will have to close due to the serious problems in the health sector.

“This discussion should be seen in context. Prof. Stulting, in his capacity as acting Head of the School of Medicine, and on behalf of the School and the Faculty, sent a proactive warning to the Free State Health Department, the Member of the Executive Committee and the Premier of the Free State regarding the long-term consequences of the health crisis. This statement was not interpreted correctly. Everything that Prof. Stulting said has already been included in the position statement that the School released in May 2009. What is urgent, though, is that the problems that were identified at especially Pelonomi Hospital in May this year were still not addressed,” said Prof. Van Zyl.

According to Prof. Van Zyl, problems at Pelonomi Hospital include not enough beds, lack of funding for the health sector in the Free State and in some instances problems with filling vacant positions.

“Some of these problems have already been addressed by the Free State Department of Health. Our training platform includes not only Pelonomi Hospital, but also Universitas Hospital, National Hospital, the Free State Psychiatric Complex and several clinics in the Bloemfontein area. This means that there are other facilities available that function in order to provide appropriate training to undergraduate students. Therefore, training is not in immediate danger and the School will definitely not be closing,” he said.

“New first-year students will start their studies in 2010 and I can assure you that there will be adequate training opportunities to take in and train students. However, we do struggle with a bigger intake as requested by Government. I want to put Prof. Stulting’s remark in context: He referred to postgraduate students and therefore the specialists who are in training,” said Prof. Van Zyl.

According to Prof. Van Zyl the specialists in training is a problem that was discussed with the Free State Health Department – with specific reference to less time in operating theatres and the number of beds at Pelonomi Hospital. “We are of the opinion that, should the Department address this problem as a matter of urgency, there will be no long-term damage to the training of these specialists in training. These are the students that Prof. Stulting was referring to,” he said.

The School received more than 1 500 applications for undergraduate studies in 2010 – all of these applications met the minimum selection requirements for the 140 available places. “Our current undergraduate students are therefore not influenced and they will continue to receive the quality training for which the School is renowned,” he said.

Prof. Jonathan Jansen, Rector and Vice-chancellor of the UFS, is aware of this and he satisfied himself as to the situation when he visited the hospitals in Bloemfontein on Friday, 9 October 2009. The national Minister of Higher Education and Training, Dr Blade Nzimande, was also informed of the School’s concerns when he visited the UFS in September 2009.
