Moonless development – Earth without Moon
Moonless development – Earth without Moon – Simulations 4 billion years of
development of the Earth without the presence of the Moon. Were performed in the
Research Center of NASA in Moffett Field, California by Jack Lisauer. In the developed model,
the maximum angle at which leaned to the axis of the Earth, turned out to be much smaller
than assumed earlier studies. The conclusions of the study were: Earth would be the Earth,
even without his extremely large satellite.
DNA chain – ladders with millions rungs
DNA chain – ladders with millions rungs – DNA strands looks like spiral ladders
with the millions rungs, each of which carries the instructions written by chemical code.
If we could unravel and stretch the DNA of a single human cell, measure the approx.
2 meters, its thickness, however, would amount to approx. 0.000002 mm. Chain DNA from
the body of one man is 16 times longer than the path from Earth to the Moon.
Galileo Galilei – In 15.02.1642 was born Italian philosopher, physicist and astronomer Galileo.
Developer basics of modern physics. He confirmed the heliocentric theory of Copernicus.
In 07.01.1610 he discovered the four largest moons of Jupiter, later named in his honor.
Solar System coldest place – space probe discovery
Solar System coldest place – American space probe Lunar Reconnaissance Orbiter (LRO), close to the pole of the Moon, on the southwestern edge of the crater Hermite discovered the coldest place of the solar system. The temperature was -249 ° C, thus lacking 24 ° C to the point of absolute zero. Substance cooled to -273.15 ° C, or to absolute zero, has no thermal energy. It is a place which does not escape any direct sunlight.
Space probe Galileo on Jupiter
Space probe Galileo on Jupiter – In October, 1989. Space shuttle Atlantis took into space probe Galileo. Did not move out of orbit straight to Jupiter, but first flew in the direction of Venus, which was used to assist gravity. In the same order twice used the Earth and finally moved toward the gas giant. Along the way, the first probe approached asteroid, specifically Gaspra, a distance of 1600 km.
Galileo probe to Jupiter was heard after 7 years and accompanied him the next 8. It became his artificial satellite. Among other things, sent into the atmosphere of Jupiter measuring instrument, which in hellish conditions lasted almost an hour. Several times flew near the Galilean moons: Io, Ganymede, Europa and Callisto. Discovered that beneath the surface of the last three is salty ocean water.
Due to the good operation of the systems, the probe mission was extended several times (the last time – at the end of April 2001.). Made a total of 34 laps around Jupiter. At that time, 7 times visited Io, Callisto 8 times, as many times Ganymede, 11 times Europe.
Blue Marble photography
Blue Marble photography – 12.07.1972. – was launched Apollo 17, the last in the American program of flights to the moon. On the same day the vehicle made famous photograph of the Earth, known as the Blue Marble, the most commonly used photography in the history of mankind. The mission of Apollo 17 flew Eugene Cernan and Harrison H. Schmitt, the last to date a man who walked on the moon. The crew of the space flight, passed the longest stay on the Moon – 74 hours 59 minutes and 38 seconds.
Lunar sports – During the Apollo 14 mission
Lunar sports – During the Apollo 14 mission in February 1971. On the surface of the Moon stood Edgar Mitchell and Alan Shepard. For a moment before returning to Earth, Shepard shot a few golf balls with a special golf club. The second cosmonaut, Mitchell threw the javelin, which remained on the lunar surface with golf balls.
Yutu Jade Rabbit – Chinese space program
Yutu Jade Rabbit – The ambitious Chinese space program Chang’e took part lunar rover Yutu (“Jade Rabbit“) – The Chinese have chosen this name in the nationwide vote. Jade Rabbit landed on the moon December 15, 2013.. According to Chinese scientists on the way Rabbit came a sharp stone, which caused extensive damage. Chinese Jade Rabbit no longer traverses the lunar plains, only slowly waiting for his death …
Moon influence sleeping – sleep and brain activity
Moon influence sleeping – Swedish researchers from the University of Gothenburg watching sleep and brain activity of 47 adults and found that the fullness shortens sleep an average of 20 minutes. In addition it makes it more difficult to us to sleep. The results indicate that our biological clock is regulated by the phases of the moon.
Neil Armstrong’s footprints – where Apollo 11 landed
Neil Armstrong’s footprints – Photos places where Apollo missions landed, made by the Lunar Reconnaissance Orbiter, shows that the footprints left there by Neil Armstrong July 21, 1969 the year you can see today. Moon hasn’t atmosphere, and hence erosion. Its surface changes only due to meteorite impacts, seismic and cosmic radiation.
