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.

Stem cell research and human cloning: legal and ethical focal points
2004-07-29

   

(Summary of the inaugural lecture of Prof Hennie Oosthuizen, from the Department of Criminal and Medical Law at the Faculty of Law of the University of the Free State.)

 

In the light of stem cell research, research on embryo’s and human cloning it will be fatal for legal advisors and researchers in South Africa to ignore the benefits that new bio-medical development, through research, contain for this country.

Legal advisors across the world have various views on stem cell research and human cloning. In the USA there is no legislation that regulates stem cell research but a number of States adopted legislation that approves stem cell research. The British Parlement gave permission for research on embryonic stem cells, but determined that it must be monitored closely and the European Union is of the opinion that it will open a door for race purification and commercial exploitation of human beings.

In South Africa the Bill on National Health makes provision for therapeutical and non therapeutical research. It also makes provision for therapeutical embryonical stem cell research on fetuses, which is not older than 14 days, as well as for therapeutical cloning under certain circumstances subject to the approval of the Minister. The Bill prohibits reproductive cloning.

Research on human embrio’s is a very controversial issue, here and in the rest of the world.

Researchers believe that the use of stem cell therapy could help to side-step the rejection of newly transplanted organs and tissue and if a bank for stem cell could be built, the shortage of organs for transplants would become something of the past. Stem cells could also be used for healing of Alzheimer’s, Parkinson’s and spinal injuries.

Sources from which stem cells are obtained could also lead to further ethical issues. Stem cells are harvested from mature human cells and embryonic stem cells. Another source to be utilised is to take egg cells from the ovaries of aborted fetuses. This will be morally unacceptable for those against abortions. Linking a financial incentive to that could become more of a controversial issue because the woman’s decision to abort could be influenced. The ideal would be to rather use human fetus tissue from spontaneous abortions or extra-uterine pregnancies than induced abortions.

The potential to obtain stem cells from the blood of the umbilical cord, bone-marrow and fetus tissue and for these cells to arrange themselves is known for quite some time. Blood from the umbilical cord contains many stem cells, which is the origin of the body’s immune and blood system. It is beneficial to bank the blood of a newborn baby’s umbilical cord. Through stem cell transplants the baby or another family member’s life could be saved from future illnesses such as anemia, leukemia and metabolic storing disabilities as well as certain generic immuno disabilities.

The possibility to withdraw stem cells from human embrio’s and to grow them is more useable because it has more treatment possibilities.

With the birth of Dolly the sheep, communities strongly expressed their concern about the possibility that a new cloning technique such as the replacement of the core of a cell will be used in human reproduction. Embryonic splitting and core replacement are two well known techniques that are associated with the cloning process.

I differentiate between reproductive cloning – to create a cloned human embryo with the aim to bring about a pregnancy of a child that is identical to another individual – and therapeutically cloning – to create a cloned human embryo for research purposes and for healing human illnesses.

Worldwide people are debating whether to proceed with therapeutical cloning. There are people for and against it. The biggest ethical objection against therapeutical cloning is the termination of the development of a potential human being.

Children born from cloning will differ from each other. Factors such as the uterus environment and the environment in which the child is growing up will play a role. Cloning create unique children that will grow up to be unique individuals, just like me and you that will develop into a person, just like you and me. If we understand this scientific fact, most arguments against human cloning will disappear.

Infertility can be treated through in vitro conception. This process does not work for everyone. For some cloning is a revolutionary treatment method because it is the only method that does not require patients to produce sperm and egg cells. The same arguments that were used against in vitro conception in the past are now being used against cloning. It is years later and in vitro cloning is generally applied and accepted by society. I am of the opinion that the same will happen with regard to human cloning.

There is an argument that cloning must be prohibited because it is unsafe. Distorted ideas in this regard were proven wrong. Are these distorted ideas justified to question the safety of cloning and the cloning process you may ask. The answer, according to me, is a definite no. Human cloning does have many advantages. That includes assistance with infertility, prevention of Down Syndrome and recovery from leukemia.
