The programme carried out six crewed spaceflights between 1961 and 1963. The program was the first program to put humans into space, with Yuri Gagarin becoming the first man in space on April 12, 1961, aboard the Vostok 1. [79] Gherman Titov became the first person to stay in orbit for a full day on August 7, 1961, aboard the Vostok 2. [80]
The program, which took its name from Roman mythology, cost $2.76 billion (adjusted for inflation). [1] [n 1] The astronauts were collectively known as the "Mercury Seven", and each spacecraft was given a name ending with a "7" by its pilot. The Space Race began with the 1957 launch of the Soviet satellite Sputnik 1. This came as a shock to the ...
The history of water supply and sanitation is one of a logistical challenge to provide clean water and sanitation systems since the dawn of civilization. Where water resources, infrastructure or sanitation systems were insufficient, diseases spread and people fell sick or died prematurely. Astronaut Jack Lousma taking a shower in space, 1974
It was a vertical test launch. Although the rocket reached space, it did not reach orbital velocity, and therefore returned to Earth in an impact, becoming the first sub-orbital spaceflight. [24] In 1949, the Bumper-WAC reached an altitude of 393 kilometres (244 mi), becoming the first human-made object to enter space, according to NASA. [25]
A fraction of this water is retained on modern Mars as both ice and locked into the structure of abundant water-rich materials, including clay minerals (phyllosilicates) and sulfates. [ 94 ] [ 95 ] Studies of hydrogen isotopic ratios indicate that asteroids and comets from beyond 2.5 astronomical units (AU) provide the source of Mars' water ...
The dates listed are launch dates, but the achievements noted may have occurred some time later—in some cases, a considerable time later (for example, Voyager 2, launched 20 August 1977, did not reach Neptune until 1989).
The issues of human dignity, morality, philosophy, culture, bioethics, and the threat of megalomaniac leaders in these new "societies" would all have to be addressed in order for space colonization to meet the psychological and social needs of people living in isolated colonies. [89]
