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]
Cosmic inflation expands space by a factor of the order of 10 26 over a time of the order of 10 −36 to 10 −32 seconds. The universe is supercooled from about 10 27 down to 10 22 Kelvins. [18] The strong interaction becomes distinct from the electroweak interaction. Electroweak epoch ends 10 −12 s 10 15 K (150 GeV)
In 1865, Secchi began classifying stars into spectral types. [96] The first evidence of helium was observed on August 18, 1868, as a bright yellow spectral line with a wavelength of 587.49 nanometers in the spectrum of the chromosphere of the Sun. The line was detected by French astronomer Jules Janssen during a total solar eclipse in Guntur ...
The program, which took its name from Roman mythology, cost $2.68 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 ...
Like the universe itself, there is no end to the number of space-related baby names. Think: the planets in the solar system (Mars), astrology (Leo) or Greek mythology (Amalthea).
The first space rendezvous was accomplished by Gemini 6A and Gemini 7 in 1965.. Records and firsts in spaceflight are broadly divided into crewed and uncrewed categories. Records involving animal spaceflight have also been noted in earlier experimental flights, typically to establish the feasibility of sending humans to outer space.
