"Curiosity" rovers landed on Mars on August 6

"Curiosity" rovers scheduled for the U.S. Eastern time at 1:31 on August 6 to Mars.
Total project investment of up to $ 2.5 billion, is by far the most expensive of the Nike shox NZ Mars exploration project, the United States, "Washington Post" So describe, which is the U.S. National Aeronautics and Space Administration a "gamble". If the "curious" errors, such a huge investment in Mars project will be halted.
"Curiosity" No. November last year, lifted off from Kennedy Space Center. It will be the surface of Mars, "Parade", "Washington Post" said, "curiosity" and the goal is not to find water, but looking for a carbon-based organics.
Since the 1960s, the United States to launch a dozen Mars probe, only six times a Mars landing. "Curiosity" can become a successful seventh, is unknown.
U.S. Space Agency, said on the 4th, "Weather Forecast", the Mars rover landing near the good weather, suitable for landing. Mars, on the 6th will be with the Nike shox Dream help of good weather, "the Aspen temperature Vasa-vada, the Mars rover project scientist, said in a press conference held on the 4th.
As planned, the "curiosity" will be landing in the Martian the Gaelic crater near the center of Mountains, the time for the Greenwich time at 5:31 on the 6th, is expected to "landing" is seven minutes long.
Vasa Wada said, near the landing point two days ago a strong dust storm, but now this dust storm has been weakened, and the hazards of dust on the rover, "cloud" is not expected to rover into the atmosphere, landing and landing constitutes any substantial impact. "
"Curiosity" landing point is scheduled to Mars the Gaelic crater center foot of the mountain. Gaelic crater is located in the south of the equator of Nike shox Dress Mars, named after the late Australian astronomer Walter Gail, formed about 350 million to 380 million years ago, about 154 km in diameter, covering an area equivalent to Connecticut, USA and Rhode Island State. Layer tilting of the crater center hill in Gaelic with clay and sulfuric acid, landing around the formation of the alluvial fan of sediment, the formation of these substances and landscapes are water-related.
The most thrilling period in the process of the whole "curious" to Mars than to enter - and fall - landing process, the stage abbreviated as EDLs, refers to the spacecraft to a speed of 5.9 kilometers per second hit the top of the atmosphere of Mars. began the landing process. EDL process lasted just seven minutes (known as the terrorist 7 minutes), the rover safely landed on the Martian surface as the end marker. From the start 10 minutes before exposure to top of the atmosphere of Mars detector discard cruise level, cut off attached to the decreased level known as the "sky crane" "curiosity" and the number of cables, the spacecraft will experience a total of six different attitude, which allows the commencement of stage action.
"Curiosity" of the landing on Mars, was undoubtedly the most exciting air suspension links. Space Agency to adopt a new "sky crane" system, about 20 meters away from the surface of Mars a high degree of Nike shox Cartoon order "curious" suspension at rest, but will put it down. Since this system has never been previously practical exercises, so the landing suspense.
Lavery, Project Officer, said, "curiosity" in the landing process, has been around Mars, the other three detectors will promptly send signals to the ground control center, control center is the fastest in 14 minutes after landing in the "curiosity" to confirm its safe landing.
U.S. Mars Society 15th annual international opening of the 3rd brightest to discuss the "curiosity". The meeting was attended by the U.S. Planetary Society President Jim Bell is no need to worry about. "I want to say that we should fully trust the engineering team, they spend years to build out the system ... they make where we landed safely."
Arizona State University, Earth and Space Exploration professor had to lead a team for the now-retired Mars Rover "Spirit" and "Opportunity" the development of Panoramic Camera color imaging system. He told the audience after the completion of the mission of "courage", stranded Mars, "it has not been stolen ... it's wheels are still ... the rover is still there a good life."
According to U.S. media reports, NASA plans to let some of the American people can see the "curiosity" board Mars live television. NASA officials said NASA's live television coverage of New York's Times Square, where the giant electronic screen synchronous playback of the scene picture. Broadcast start time from the U.S. Eastern time at 23:30 on August 5th (continued until 4:00 am the next day.
John glycopyrrolate Rumsfeld, assistant administrator of Nike shox Torch NASA's Science Mission Directorate, said in a statement: "In the city that never sleeps, Times Square is to allow New Yorkers to participate in this historic event, a good place when you recall the history of All major events, you will think of Times Square, I can not think of what better place to commemorate the big news from Mars.
