Jericho is a general designation given to a loosely-related family of deployed ballistic missiles developed by Israel since the 1960s. The name is taken from the first development contract for the Jericho I signed between Israel and Dassault in 1963, with the codename as a reference to the Biblical city of Jericho. As with some other Israeli high tech weapons systems, exact details are classified, though there are observed test data, public statements by government officials, and details in open literature especially about the Shavit satellite launch vehicle.
The Prince Edward Islands are two small uninhabited volcanic islands in the sub-Antarctic Indian Ocean that are administered by South Africa. They are named Marion Island and Prince Edward Island.
The Astronomical Society of Southern Africa (ASSA), formed in 1922, is a widespread body consisting of both amateur and professional astronomers. There are eight autonomous centres throughout Southern Africa.
The Vela incident was an unidentified double flash of light detected by an American Vela Hotel satellite on 22 September 1979 near the South African territory of Prince Edward Islands in the Indian Ocean, roughly midway between Africa and Antarctica. Today, most independent researchers believe that the flash was caused by a nuclear explosion—an undeclared joint nuclear test carried out by South Africa and Israel.
From the 1960s to the 1990s, South Africa pursued research into weapons of mass destruction, including nuclear, biological, and chemical weapons under the apartheid government. South Africa’s nuclear weapons doctrine was designed for political leverage rather than actual battlefield use, specifically to induce the United States of America to intervene in any regional conflicts between South Africa and the Soviet Union or its proxies. To achieve a minimum credible deterrence, a total of six nuclear weapons were covertly assembled by the late 1980s.
Secunda is a town built amidst the coalfields of the Mpumalanga province of South Africa. It was named for being the second Sasol extraction refinery producing oil from coal, after Sasolburg, some 140 kilometres (87 mi) to the west.
The following lists events that happened during 1993 in South Africa.
Sasol Limited is an integrated energy and chemical company based in Sandton, South Africa. The company was formed in 1950 in Sasolburg, South Africa, and built on processes that German chemists and engineers first developed in the early 1900s. Today, Sasol develops and commercializes technologies, including synthetic fuel technologies, and produces different liquid fuels, chemicals, coal tar, and electricity.
Coal liquefaction is a process of converting coal into liquid hydrocarbons: liquid fuels and petrochemicals. This process is often known as "Coal to X" or "Carbon to X", where X can be many different hydrocarbon-based products. However, the most common process chain is "Coal to Liquid Fuels" (CTL).
The South African Astronomical Observatory (SAAO) is the national centre for optical and infrared astronomy in South Africa. It was established in 1972. The observatory is run by the National Research Foundation of South Africa. The facility's function is to conduct research in astronomy and astrophysics. The primary telescopes are located in Sutherland, which is 370 kilometres (230 mi) from Observatory, Cape Town, where the headquarters is located.
Concor Holdings (Proprietary) Limited. is a South African construction and mining services company. It is active throughout Southern Africa, involved in civil engineering, buildings, roads and mining projects. Concor returned as an independent brand in late 2016.
The military history of South Africa chronicles a vast time period and complex events from the dawn of history until the present time. It covers civil wars and wars of aggression and of self-defence both within South Africa and against it. It includes the history of battles fought in the territories of modern South Africa in neighbouring territories, in both world wars and in modern international conflicts.
The South African National Antarctic Programme is the South African government's programme for research in the Antarctic and Subantarctic. Three research stations fall under this programme: the Antarctica research station SANAE IV, and one station each on the subantarctic islands Gough Island and Marion Island. These stations are managed and administered by the Directorate: Antarctic and Islands of the Department of Environmental Affairs. Borga Base was also operated by SANAP from 1969 to 1976.
Michiel Daniel Overbeek, also known as Danie Overbeek, was a South African amateur astronomer and one of the most prolific variable star observers.
South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. Its nine provinces are bounded to the south by 2,798 kilometres of coastline that stretches along the South Atlantic and Indian Ocean; to the north by the neighbouring countries of Namibia, Botswana, and Zimbabwe; to the east and northeast by Mozambique and Eswatini; and it encloses Lesotho. Covering an area of 1,221,037 square kilometres, the country has over 62 million people. Pretoria is the administrative capital, while Cape Town, as the seat of Parliament, is the legislative capital. Bloemfontein has traditionally been regarded as the judicial capital. The largest and most populous city is Johannesburg, followed by Cape Town and the busiest port city in sub-Saharan Africa, Durban.
S. A. Agulhas is a South African ice-strengthened training ship and former polar research vessel. She was built by Mitsubishi Heavy Industries in Shimonoseki, Japan, in 1978. S. A. Agulhas was used to service the three South African National Antarctic Programme research bases, Gough Island, Marion Island in the Southern Ocean and SANAE IV in Antarctica, as well as various research voyages.
As of 2011, South Africa produces in excess of 255 million tonnes of coal and consumes almost three-quarters of that domestically. As of 2018, South Africa was the seventh largest producer and consumer of coal in the world. The industry, as of 2015, employs about 80,000 workers, or .5% of total employment, down from a peak in 1981 of 135,000 workers. The coal industry is South Africa's largest contribution to the greenhouse gases that cause climate change.
South Africa has a large energy sector, being the third-largest economy in Africa. The country consumed 227 TWh of electricity in 2018. The vast majority of South Africa's electricity was produced from coal, with the fuel responsible for 88% of production in 2017. South Africa is the 7th largest coal producer in the world. As of July 2018, South Africa had a coal power generation capacity of 39 gigawatts (GW). South Africa is the world's 14th largest emitter of greenhouse gases. South Africa is planning to shift away from coal in the electricity sector and the country produces the most solar and wind energy by terawatt-hours in Africa. The country aims to decommission 34 GW of coal-fired power capacity by 2050. It also aims to build at least 20 GW of renewable power generation capacity by 2030. South Africa aims to generate 77,834 megawatts (MW) of electricity by 2030, with new capacity coming significantly from renewable sources to meet emission reduction targets. Through its goals stated in the Integrated Resource Plan, it announced the Renewable Energy Independent Power Producer Procurement Programme, which aims to increase renewable power generation through private sector investment.
