It was originally known as the "250 ft telescope" or the Radio Telescope at Jodrell Bank, before becoming the Mark I telescope around 1961 when future telescopes (the Mark II, III, and IV) were being discussed. Lovell telescope. Learn more about our use of cookies. Sir Alfred Charles Bernard Lovell OBE FRS, born on 31 August 1913, was an English physicist and radio astronomer. The final part of the debt from the construction of the telescope, £50,000, was paid off by Lord Nuffield and the Nuffield Foundation on 25 May 1960[35] (partly due to the telescope's early, very public role in space probe tracking; see below), and Jodrell Bank observatory was renamed to the Nuffield Radio Astronomy Laboratories. It also received data from Pioneer 5, and was the only telescope in the world capable of doing so at the time. Construction of the telescope had begun in 1952 and by 1957, it was almost complete. It has been upgraded several times since then and has now completed three phases of its most recent four-step upgrade program. (source: The Telegraph. First, the rusting sheet-metal surface panels were replaced with galvanized steel plates (used instead of aluminum to keep the bowl structure in balance). [25] Also, in February 1954 Lovell and the Air Ministry met to see if funding could be made available for improving the accuracy of the dish so that it could be used on centimetre wavelengths, for research at these wavelengths for the Ministry as well as "other purposes". Photo courtesy of Jodrell Bank. The 76-meter (250-foot) radio telescope was built in 1957 and has long been an icon of British science. [85] It has also been used in Very Long Baseline Interferometry, with telescopes across Europe (the European VLBI Network), giving a resolution of around 0.001 arcseconds. [66] Also, the telescope tracked Luna 9 in February 1966, the first spacecraft to make a soft landing on the Moon. Due to increases in the cost of steel during the upgrade, the final amount for the upgrade was £664,793.07. It has a 250ft (76.2m) diameter and was the largest steerable dish telescope in the world when it was commissioned in 1957. [27] Instead, receivers were mounted on 50-foot (15-m) long steel tubes, which were then inserted by a winch into the top of the aerial tower while the bowl was inverted. When the Lovell Telescope was built in 1957, it was expected to be in use about 10 years. [38] The telescope was therefore repaired and upgraded to become the Mark IA; the £400,000 of funding to do this was announced on 8 July 1968 by the SRC. The telescope tracked Mars 1 in 1962–3,[61] and Mars 2 and Mars 3 in 1971 (amidst the upgrade of the telescope to the Mark IA). The telescope's inspiration, Sir Bernard Lovell, said: "When built, the telescope had only been expected to have an operational life of some 10 years. The Lovell Telescope was first used in 1957 to track the launch rocket of Sputnik 1 at the dawn of the space age. In 1987, on its 30th birthday, the MkIA radio telescope was renamed the Lovell Telescope. The telescope was replaced by the steerable 250 ft Lovell Telescope and the Mark II telescope was subsequently built at the same location. [84], In 1968, the telescope observed the coordinates of the recently discovered pulsar, confirming its existence and investigating the dispersion measure. Read more about Jodrell Bank. Huge engineering challenges included how to move 2,000 tonnes with accuracy at a quarter of an inch per minute, how to avoid resonance frequency (that had destroyed the Tacoma Narrows Suspension Bridge in 1940), and how to compensate for the changing weight distribution as the dish was tilted and it turned. Sir Bernard Lovell, first Director of the Observatory and instrumental in the building of the telescope, watched as the new surface was revealed. The telescope listened in on its facsimile transmission of photographs from the moon's surface. This was then used to determine the 2D shape of quasars on the sky. Home → What’s On → News → The Lovell Telescope And Sputnik 1. The cables from the receivers then ran down the inside of this tube, which could then be connected when the telescope was pointed at the zenith. [95] In the summer of 1961, a 25-foot (8-m) diameter paraboloid telescope was constructed (it was made of aluminium tubing and was mounted on the rotating structure of an old defence radar). 300 pulsars are regularly observed using either the Lovell, or a nearby 42-foot (13-m) dish. The Lovell Telescope is a radio telescope at Jodrell Bank observatory in Cheshire in the north west of England. The telescope could map a ± 15-degree strip around the zenith at 72 and 160 MHz, with a resolution at 160 MHz of 1 degree. James Randerson. The structure has been upgraded several times since it was built. [47] A new drive system was installed, which provides a much higher pointing accuracy. He may even have been the subject of a Cold War assassination attempt. In terms of American space probes, the telescope tracked Pioneer 1 from 11 to 13 November 1958,[59][60] Pioneer 3 in December 1958,[61] and Pioneer 4 in March 1959. When it was built in … Lovell telescope. These are the only two wheel changes needed since the telescope started operation in 1957.[49].

Home  →  What’s On  →  News  →   The Story of the Lovell Telescope. [90], Between 1972 and 1973, the telescope was used for "a detailed survey of the radio sources in a limited area of the sky … up to the sensitivity limit of the instrument". [85] OH masers emit on four frequencies around 18 cm (7 in), which are easily observable on the telescope. It is truely magnificent." BORN: 31 August 1913 [27] However, the movable tower was never built, due jointly to funding constraints and the fact that much of the receiver equipment was placed at the base of the telescope rather than at the focus. When it was built in 1957 the Lovell telescope was the largest in the world and cost £750,000. [58], The Lovell Telescope was used to track both Soviet and American probes aimed at the Moon in the late 1950s and early 1960s. The new Lovell Telescope will be used to discover new distant pulsars, study the formation of stars in our own galaxy and seek out faint radio galaxies and quasars in the far reaches of the Universe. [10][11], Two circular 15" turret drive gear sets and associated pinions from 15-inch (38-cm) gun turrets were bought cheaply in 1950; these came from the World War I battleships HMS Revenge and Royal Sovereign, which were being broken up at the time.
