Moon landing. Clickable imagemap of the locations of all successful soft landings on the Moon to date.
Dates are landing dates in UTC. Still frame from a video transmission, taken moments before Neil Armstrong became the first human to step onto the surface of the Moon, at 02:56 UTC on 21 July 1969. An estimated 500 million people worldwide watched this event, the largest television audience for a live broadcast at that time.[1][2] Luna 2. Luna 2 site is near the right of the image, close to the Apollo 15 landing site Launch was scheduled for September 9, but the Blok I core stage was shut down after it failed to reach full thrust at ignition.
The booster was removed from the pad and replaced by a different vehicle, delaying the flight by three days. Luna 2, like Luna 1, took a direct path to the Moon with a journey time of around 36 hours. This was dictated by the fact that the Earth-Moon gravitational system forced it to follow a curved trajectory, and launch had to occur from the side of the Earth opposite the Moon. Its journey time had to be, therefore, 12 hours, 36 hours or 60 hours in order to ensure that the Moon was above the horizon in the Soviet Union. Luna 2 was similar in design to Luna 1, a spherical spacecraft with protruding antennas and instrument parts. Van Allen Radiation Belt[edit] Luna 2 showed time variations in the electron flux and energy spectrum in the Van Allen radiation belt. USSR pennants[edit] Lunokhod programme.

Soviet moonrover Development[edit] Parabolic dish TNA-400 and abandoned NIP-10 Lunokhod's original primary mission was the survey of sites for later manned landings and lunar bases. It was intended that the spacecraft would provide a radio beacon for precision landings of manned spacecraft. At least four complete vehicles were constructed, with the serial numbers 201, 203, 204 and 205. Lunokhod 201[edit] After years of secret engineering development and training, the first Lunokhod (vehicle 8ЕЛ№201) was launched on February 19, 1969. Lunokhod 1[edit] Lunokhod 1 robot vehicle After the destruction of the original Lunokhod, Soviet engineers began work immediately on another lunar vehicle.
Luna 17 was launched on November 10, 1970 at 14:44:01 UTC. Voyager Golden Record. Cover of the Voyager Golden Record The Voyager Golden Records are phonograph records which were included aboard both Voyager spacecrafts, which were launched in 1977.
They contain sounds and images selected to portray the diversity of life and culture on Earth, and are intended for any intelligent extraterrestrial life form, or for future humans, who may find them. Yuri Gagarin. Gagarin became an international celebrity, and was awarded many medals and titles, including Hero of the Soviet Union, the nation's highest honour.
Vostok 1 marked his only spaceflight, but he served as backup crew to the Soyuz 1 mission (which ended in a fatal crash). Gagarin later became deputy training director of the Cosmonaut Training Centre outside Moscow, which was later named after him. Gagarin died in 1968 when the MiG-15 training jet he was piloting crashed. Early life and education Yuri Gagarin was born in the village of Klushino, near Gzhatsk (renamed Gagarin in 1968 after his death), on 9 March 1934.[1] His parents worked on a collective farm:[2] Alexey Ivanovich Gagarin as a carpenter and bricklayer, and Anna Timofeyevna Gagarina as a milkmaid.
Moon landing. 3C 321. 3C 321 is a system of two galaxies rotating around each other.
They are notable for showing the first observed galaxy smiting another galaxy with a blast of energy, which is theorized to be from a supermassive black hole at the center of the former galaxy. The larger galaxy, dubbed the "Death Star Galaxy" by NASA astronomers, has an energetic jet directed towards its companion. The discovery was announced by NASA Dec 18 2007. Observation of the enormous jet was possible due to the combined efforts of both space and ground-based telescopes. Tools included NASA's Chandra X-ray Observatory, the Hubble Space Telescope, Spitzer Space Telescope, the Very Large Array-VLA, and the Multi-Element Radio Linked Interferometer Network.
References[edit] Earth's shadow. The Earth's shadow or Earth shadow (also sometimes known as the dark segment) are names for the shadow that the Earth itself casts on its atmosphere.
This shadow is often visible from the surface of the Earth, as a dark band in the sky near the horizon. This atmospheric phenomenon can sometimes be seen twice a day, around the times of sunset and sunrise. Gomez's Hamburger. Gomez's Hamburger is believed to be a young star surrounded by a protoplanetary disk.[1] It was initially identified as a planetary nebula (i.e. an old dying star), and its distance therefore wrongly estimated to be approximately 6500 light-years away from planet Earth.[2] However, recent results suggest that this object is a young star surrounded by a protoplanetary disk whose distance is only around 900 light-years away.[1][3]
