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.

Achieving programme accreditation from the respective professional bodies is the ultimate goal for the Department of Quantity Surveying and Construction Management at the University of the Free State (UFS). This is according to Prof Kahilu Kajimo-Shakantu, the head of this department. This hallmark of quality reflects the university’s aspiration towards excellence.

Construction Management programmes reviewed
The university recently received a visit by a panel, representing the South African Council for the Project and Construction Management Professions (SACPCMP) to re-accredit programmes offered by the Department of Quantity Surveying and Construction Management. During the accreditation visit, the panel evaluated the programmes to determine whether they met the minimum requirements according to a set of pre-determined criteria.

When reviewing the programmes: BSc and BSc Hons Construction Management respectively, as well as the Project Management stream of the Masters programme in Land and Property Development Management (MLPM), the panel looked at programme design and outcomes including curriculum, study material and exam papers, institutional support, student recruitment, admission, development, retention and throughput, staffing recruitment and development, teaching and learning strategies, quality assurance, facilities, infrastructure and resources, professional development, industry and practical exposure and postgraduate policies, procedures and regulations, including research activities.

If the minimum requirements are achieved, the Department of Quantity Surveying and Construction Management at the UFS will receive accreditation for its programmes from 1 April 2017 to 31 March 2022.

It will also mean that we are certified
as producing quality employable
graduates who are well prepared to
enter the industry and make a difference.

Currently, the department has full accreditation by the SACPCMP (until March 2017) and the SACQSP (until December 2017).

Later this month, a panel from the South African Council for Property Valuation Profession (SACPVP) will review the accreditation of the Valuation stream of the MLPM programme. The South African Council for Quantity Surveying Profession responsible for accrediting the Quantity Surveying programmes will visit the university in 2018.

Certified as producing quality students
Prof Kajimo-Shakantu said: “If we maintain our accreditation, it will reflect that the UFS is among the best, with programmes which are recognised by professional bodies that set competence standards for professional registration of students. It will also mean that we are certified as producing quality employable graduates who are well prepared to enter the industry and make a difference. The programmes contribute to the development of the much-needed critical skills in the built environment.”
