05 Feb 1974 Venus probe	science	Venus probe In 1974, the U.S. space probe Mariner 10 returned the first close-up photos of the cloud structure of Venus, at a closest range of 5768-km. It also was the first time a spacecraft used a gravity assist from one planet to help it reach another planet, helping Mariner 10 reach Mercury in Mar 1974. Carbon dioxide and sulphuric acid make up the Venusian atmosphere and clouds, having a greenhouse effect that heats the surface to 485ºC, while obscuring any view of the planet's surface, where the atmospheric pressure is 90 times greater than at sea level on Earth. The Soviet probe Venera 9 which penetrated the clouds and landed on 22 Oct 1975, was briefly able to transmit images of the surface.

07 Jul 1974 Lyman C. Craig	science	death Lyman C. Craig Died 7 Jul 1974 at age 68 (born 12 Jun 1906). Lyman Creighton Craig was an American chemist who developed the counter-current distribution (CCD) method. Within five years of earning his Ph.D., he had designed and built a microdistillation apparatus (1936). Wartime research on antimarial drugs required identification of microgram amounts of an organic compound in a mixture, for which he devised a laboratory technique based on the distribution coefficient. He soon developed the CCD method for fractionation of complex mixtures with an apparatus that could simultaneously accomplish 20 quantitative extractions in a single step. A notable separation, from a difficult mixture, was the isolation and purified parathormone, the active principle of the parathyroid gland, achieved in 1960 with his colleagues. Craig also designed several other significant instruments, including his rotary evaporator, among others.
13 Jul 1974 Patrick M.S. Blackett	science	death Patrick M.S. Blackett Died 13 Jul 1974 at age 76 (born 18 Nov 1897). (Baron Blackett of Chelsea) Patrick Maynard Stuart Blackett was an English physicist and winner of the Nobel Prize for Physics in 1948 for his discoveries in the field of cosmic radiation. In these studies he used cloud-chamber photographs that revealed the way in which a stable atomic nucleus can be disintegrated by bombarding it with alpha particles (helium nuclei). Although such nuclear disintegration had been observed previously, his data explained this phenomenon for the first time and were useful in explaining disintegration by other means.
