Curiosity NASA Find Water on Mars

Within the first three months on Mars, NASA's Curiosity robot look unique diversity on the surface of Mars. Robots have examined soils and sediments along the route cruising the red planet.

After half a mile crawl Curiosity Mars in the early days after the landing, the robot wheels reportedly found on the red planet survive drying. Dust and fine soil had reportedly contains a small amount of water.

"We made this discovery is true with the first laser shot on the Red Planet," said Roger Wiens, ChemCam instrument team leader. He said, whenever Curiosity dust shot, the team then looked and saw a significant hydrogen.

In some papers that reveal debut Curiosity on Mars, the Los Alamos researchers use ChemCam instrument on Curiosity to collaborate with international scientists, Chemin, APXS, and SAM instruments to describe the history of volcanic and water on Mars.

Researchers believe, hydrogen seen in the dust coming from the water. This hypothesis is strengthened by the SAM instrument Curiosity, which shows all found in the Martian soil contains between 1.5 to 3 percent water.

Curiosity rover to explore Mars is scheduled for one more year. Within a few months, Curiosity will travel to Mount Sharp, which is the peak towering to a height of nearly three miles.

Mount Sharp is believed to contain sediment layers that reveal the history of Mars billions of years ago. Scientists need information about Mount Sharp to uncover the history of the red planet's climate and geology.

Could it be that the Asteroid will Hit the Earth

Head of the U.S. space agency NASA, Charles Bolden revealed how it can handle a large asteroid that reportedly will approach Earth. This space rock is heading right now predictable over the skies of New York City.

In such a case, Charles reveals that all parties should pray. In addition, it hopes to be able to avoid things that are undesirable due to the possibility of the asteroid threat.

Charles said, this is about all of the United States or anyone else for that matter, who could do something about the asteroid which is now rumored to be on track with the Earth. Bolden brought this to MPs in the House of Representatives Science Committee of the United States.

Landing event space objects or meteor had happened some time ago in Russia. Meteor is estimated to have a diameter of 55 feet (17 meters) causing injuries to 1,500 people due to the shock wave broke the glass and damage to buildings.

This event, he said, are proof that humans live in an active solar system with objects potentially dangerous. Eddie Bernice Johnson of Texas Democrat said, these asteroids have approached the Earth with surprising frequency.

"We are very fortunate that the incident last month was just a simple coincidence rather than a disaster," said Committee Chairman Lamar Smith. NASA discover and browse approximately 95 percent of the space object approaching Earth.

Of the asteroid is detected, the largest asteroid has a diameter of 1 kilometer wide. "An asteroid that size, one kilometer or larger, it makes sense to be able to put an end to civilization," said John Holdren, the White House Science Advisor.

Material Asteroid High Sales Value

The company carries asteroid mining project, Deep Space Industries some time ago had echoed the call of their work space rock would be a gold fields in 2015. Large asteroid that reportedly will cross the Earth in February 15, 2013 also encouraged them to estimate the value that can be generated when the asteroid was successfully mined. Asteroid 2012 DA14 which supposedly can be seen also in the sky Sumatra, Indonesia has the minerals and metals, which when cashed worth USD195 billion.

Scientists have warned that the space rock will be approached and crossed at the closest distance to the Earth. Deep Space Industries fairly certain that some of the material in the asteroid mining is not a bad idea. They estimate, 2012 DA14 contains 5 percent of the water that can be recovered. Of course the water element, reportedly has generated USD 65 billion.

In addition to the element of water, iron, nickel and other metals estimated at USD130 billion. However, valuation is still a rough calculation. Scientists need to look at how well the composition of the asteroid or size. However, it also proves asteroid mining operations more complicated. However, reportedly, track asteroid 2012 DA14 was in a position that is less appropriate to do mine asteroids. In addition, the required energy to pursue the asteroid's trajectory.

Potentially Habitable Planets

Researchers from Pennsylvania State University (USA) examines the habitable zone in space for Earth-type planets. Using research related to water and carbon dioxide molecules, the researchers concluded that the planet could still potentially habitable planet when it was far from the sun.

This research is important for planning future projects to find extrasolar planets. But it seems that researchers are still constrained on technology, the author's work, as well as criticism of the study.

One of the points driving to the search for planets outside the solar system is dependent on what researchers have discovered at this time. Total foreign planet, which is called the new world has been growing rapidly.

Nearly 700 objects identified as exoplanets around stars. More than 2,000 candidates found by Kepler space telescope.

The position of the planet called habitable zone, a selection criteria. The zone is a region of space around a star, where the mass of the Earth and the planets of similar composition atmosphere (nitrogen, water, carbon dioxide) can raise liquid water on its surface.

Scientists say there is no liquid water on the surface of the Earth's two nearest planets, namely Venus and Mars. Not only the temperature of the star, but also the composition and properties of the atmosphere affects the habitable zone boundaries.

This study also used data from the distance between the Earth to the Sun, which is 1.5 million kilometers. The team of researchers from Pennsylvania State University, NASA, Washington University and the University of Bordeaux dubious previous research models in 1993.

The previous model predicts that border the habitable zone of the Sun internal and external, are between 0.95 and 1.67 astronomical units. Researchers now want to update these inaccuracies, using the absorption of solar radiation.

Antidote Giant Asteroid

NASA, the National Aeronautics and Space Administration reportedly would consider to capture a giant asteroid. By capturing large asteroids and placed in high orbit around the moon, then it is likely the object space would not threaten the Earth in 2020.

NASA confirmed that it will pay high attention related to the project and the move is expected to bear fruit in 2020.

According to New Scientist, the idea to divert the asteroid lane is associated with enthusiasm by U.S. President Barack Obama to send manned missions to near-Earth asteroids. If NASA robot can pick and place objects in space that orbit around the moon, the crew of the space shuttle can be involved without the need to move beyond the reach of rescue mission.

NASA set the time for 6 to 10 years and see spacecraft moves towards the target asteroid. Then, NASA asteroid will catch them in a big bag and send it back to the moon.

Potential uses to be included NASA as anticipatory measures, one of them using the object space. Object space is expected to be used as a source of fuel or building materials for space missions, including support for the mission trip to Mars.

The Flow of Water Found on Mars

Mars rover robot creations National Aeronautics and Space Administration (NASA) found evidence related to the flow of water that have occurred on Mars. These findings provide evidence of the early existence of water on the red planet. This evidence suggests the rocks that once fed by the water and this is the first of its kind. "From the size of pebbles, we interpret the water was moving about 3 feet per second range in depth from ankle to hip," says scientist William Dietrich University of California at Berkeley.

He said many studies reveal about the channels on Mars with a variety of different hypotheses about the flow of water in it. This is the first time that scientists see gravel carried by the flow of water on Mars. Curiosity found this site which is located between the northern part of Gale Crater and the base of Mount Sharp. Initial image captured through the orbit of Mars may provide additional understanding of these pebbles.

A captured image shows alluvial material washed by the water and move to the edges. Spherical shape of some of the rock shows it moving from a distance, where the channel called Peace Vallis pointed to the alluvial fan. The number of channels in the alluvial fan indicates that water flows in continuous motion. The flow was also repeated each time in a long time, not just once or over several years.

Asteroids that Will be a Moon

Along with small asteroids trapped by gravity, and spend more time to circle the Earth, one might say that the asteroid into hundreds of small moon orbiting around Earth. Researchers have long suspected asteroids that pass, sometimes approaching the Earth at a distance close enough to be trapped by gravity. Asteroids is exactly what will be a moon while.

Mikael Granvik from the University of Helsinki in Finland, along with his colleagues run a computer simulation, to find the frequency of various near-Earth asteroids, and their likelihood of being caught gravity when approached. To be caught, an object must start out of the orbit is quite identical with the Earth. Team estimates that, on average, an asteroid with a size of 1 yard or 1,000 space rock measuring approximately 4 inches, may be orbiting the Earth.

 "There's a lot more than people might think," said Mikael Granvik. These asteroids, generally stay in orbit around the Earth for less than one year. Although the simulations were done by researchers, also expressed some asteroids may have stayed longer.
