2015 will be the human space and planetary exploration missions rewarding year, wonderful good show will be staged continuously, comb your article to attract the eye of the highlights of this year's event.
Opportunity
This year is the Opportunity rover successfully landed on Mars, the 11th anniversary of the day, the scene shown in the figure is arrived at Endeavour Opportunity hit nearby pit, scientists here named "Cape Tribulation."
Since 2008 after leaving Victoria Crater, which Opportunity is the highest point reached. This solar robot weighing 180 kg took three years to complete the journey to reach the Endeavour crater, the crater 14 miles in diameter (about 22.5 km), is the way this car Rover visited the largest crater.
An important task is to search for Opportunity rocks and soil characteristics to look for in the past if there was water flowing.
Dawn spacecraft br / March of this year, NASA's Dawn probe enters orbit the dwarf planet Ceres. Ceres is the largest known asteroid belt located objects. December 18, 2014, the American Institute of Planetary Sciences scientist Lijian Yang said: "I do not think astrobiology Ceres than other potential livability of the planet for life requires three basic conditions - liquid water, energy sources. and certain chemical composition (carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur, etc.), Ceres account for a certain advantage. "and previous studies have confirmed that there are a lot of ice inside.
NASA also released the results of the detection of the asteroid Vesta Dawn surprising that scientists once thought that asteroids are extremely dry, because the asteroid not retain water. However, the latest research shows that Vesta surface liquid water, there have been brief, these features have been considered only in the planets appear. So NASA issued a statement he said. "Vesta proved to be a very interesting and complex objects."
MESSENGER Mercury MESSENGER probe br / (Photograph: Mercury surface, space environment, geochemistry and extensively explored) is a NASA satellite detected in August 3, 2004 launch, in order to study Mercury's environment and characteristics enter orbit in 2011. mESSENGER is the mariner 10 mission after the first detection of human Mercury program.
Scientists will ignite its last booster in 2015, so that the detector can work at a height sufficient to March. But by that time, the detector will be very close from the Mercury, could lead to some welding materials in its structure to melt.
25-year-old Hubble April 25, 2015 the Hubble Space Telescope will be at least 25 years old. April 25, 1990, by the US space shuttle into orbit of "Hubble" telescope 13.3 meters long, 4.3 meters in diameter and weighs 11.6 tons, cost nearly $ 3 billion. Despite some early problems, but also experienced several repairs, but still powerful Hubble. It is expected to continue to work until 2018, until the James Webb Space Telescope started.
New Horizons probe
New Horizons spacecraft in 2006 January 19 to leave the Earth, whose main task is to detect has been downgraded to a dwarf planet Pluto and its largest moon Charon and the Kuiper belt asteroid probe located group. This will give us the opportunity to provide the first close observations of the outer solar system objects. From January to Pluto began a preliminary observation, but the best observation point was July 14, New Horizons probe flew dwarf planet at the moment.
Rosetta probe
November 13, 2014 early morning, after up to seven hours after a long wait, the Rosetta comet probe release of "Philae 'lander successfully landed on 67P / Churyumov-Gerasimenko comet. And will enter the comet orbits the sun continues its journey to the comet in the company. Scientists estimate that the detector closest to the sun was on August 13, 2015.
Rosetta's mission is what will change when monitoring comet close to the sun. It hopes enough sunlight to meet the "Philae" work to solar panels, so that now in hibernation state 'Philae' lander timely wake up to collect more data.
Cassini In October 2008 NASA's Cassini mission is close overflew Enceladus. The overflights allow Cassini Enceladus Enceladus found evidence of the existence of the Antarctic underground ocean of liquid water, and ice near the south pole of the volcano ejected into space a lot of water vapor and other volatiles.
Goodbye, Voyager 2 br / Voyager 2 visited the planet mission has ended, it will be at some point in 2015 to beyond the solar system.
Voyager 1 and Voyager 2 spacecraft were launched in 1977, Pioneer 10 the farthest man-made objects in the solar system was launched in 1972. US space NASA said: Pioneer 10th at January 23, 2003 came last after a very weak signal, it lost contact with Earth. Voyager spacecraft continues to send information.
These are a few bright spots this year space mission highlights, 2015 will be the most anticipated of human space exploration is of great significance for one year.
