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.

Antarctic temperature changes

Antarctic temperature changes

Antarctic temperature changes – Researchers at the University of Washington in Seattle (USA),
after analyzing
data from satellites observing Antarctica, came to the conclusion that Antarctica
warmed
by 0.5 ° C between 1957 and 2006. Scientists noticed that the temperature
quickly
rises to the west Antarctica. Heating the continent has an impact on rising sea levels.

Space probe Galileo on Jupiter

Space probe Galileo on Jupiter - Io and Jupiter

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.

Solar wind – The Sun has an impact on the processes

Solar wind – The Sun has an impact on the processes

Solar wind – The Sun has an impact on the processes in the solar system in many different ways. Although gravity is maintained thanks to its system time emits a space wide range of molecular types of radiation, to which the feature ” wind of the Sun”. Researchers from the University of Leicester have combined the data. Obtained during the observations of solar activity from data obtained during observations of the Martian atmosphere, provided by satellites. The solar corona disappears from the environment until 2.5 x more particles. Observations were conducted during the fall of solar activity within the 11 – year solar cycle.

GPS system – It uses 31 satellites orbiting the Earth

GPS system - GPS Receivers

GPS system

GPS system – It uses 31 satellites orbiting the Earth. Each is equipped with an atomic clock and emits signals in which encoded is its location and the clock. Satellites are close to 20 thousands km. above the Earth. The attraction is there so much weaker satellites clocks ahead of the Earth about 38 millionths of a second a day. To get the accuracy of 10-15 meters, the GPS receiver needs to know the super-accurate time transmission of the satellite signal.  Error no greater than 50 nanoseconds.

NASA Plan for 2020

NASA Plan for 2020 - Telescope EUCLID

NASA Plan for 2020

NASA Plan for 2020 – NASA in 2020. Activate EUCLID telescope that will map the shape, brightness, and portrayed the space of two billion galaxies. With this satellite scientists try to understand the role played bydark matter” and “dark energy in the history of the cosmos. The project will involve nearly 1 thousand scientists from around the world. 40 of them are experts NASA.

Earth’s magnetic field weakening

Earth's magnetic field weakening - North magnetic pole

Earth’s magnetic field weakening

Earth’s magnetic field weakening – Swarm mission, launched by the European Space Agency (ESA), launched in 11.2013. Satellites of this mission performed photos, which showed that the magnetic field of our planet is still weakening. The measurements confirmed the movement of the Earth’s North Pole to Siberia. Scientists will now investigate whether this is a temporary trend, or constant.

Optical fibers connecting continents

Optical fibers connecting continents

Optical fibers connecting continents – Currently, optical fibers connect all continents except Antarctica, which is connected with the world via satellites. At the bottom of the ocean is approx. 400 thousand. km wires. The longest measured up to 39 thousand km. Called SEA-ME-WE 3, which is an acronym of places, which connects – South – East Asia, the Middle East and Western Europe. Also extends to Africa, and one branch goes up to Australia. Since 2000., When the completed network, optical fiber link 33 countries from 4 continents.

Phobos

Phobos – One of the two moons of Mars

Phobos – One of the two moons of Mars resembles its shape potato cratered. Red Planet caught the flying asteroid and made it their satellite. Phobos looks like it went through a herd of worms, because the inside is full of holes. The object awaits the sad fate of Mars, Phobos still draws closer and for approx. 50 million years, tidal forces of Mars moon tear to shreds. Thanks to the Red Planet will become a decoration in the form of a ring.
