The world's first satellites outside the earth's orbit transmit a radio signal to our planet

NASA indicating a radio signals received that the world's first satellites of the "kubsat" format, moving in outer space beyond the limits of the orbit of our planet, are in good working order and operate in the regular mode. The first signal was received yesterday at 20:15 UTC, and the second - almost two hours after the first - at 21:58 UTC. 

NASA has shown a unique picture of the Martian surface

Scientists of the American space agency NASA have published on the official website of the agency a unique picture of the Martian surface.

Based on this and other images of the Red Planet,

Giant comet to pass Mars for the first time in a million years

The closest look ever at a new comet will happen when the mountain-size comet Siding Spring buzzes past Mars this weekend. The comet will buzz the Red Planet on October 19. NASA

A comet on a once-in-a-million-years journey will graze the atmosphere of Mars, astronomically speaking, this Sunday. 

Man on mars

The Red Planet has been getting a lot of attention recently, between India's low-cost MOM probe entering Mars's orbit, NASA's MAVEN doing the same, and the Curiosity rover reaching the most potentially fertile site yet for signs of ancient life. Elon Musk has even talked about building a city there. For most people who look out at the night sky and wonder whether we're alone, Mars holds our best hope for proving that we're not.

New research Curiosity

Moving away from the forced hibernation, the rover “Curiosity " immediately proceeded to new research. He even made a fence of new samples of Martian soil and made it into powder with its onboard scientific instruments. Now, the rover is ready to perform a complete chemical and spectral analysis of the obtained powder and send the results to Earth at the Jet Propulsion Laboratory (NASA).

Curiosity found on Mars, radiation is not dangerous for humans

Radiation levels on the surface of the Red Planet is equivalent to environment radiation in low Earth orbit, NASA discovered Martian rover Curiosity.

The first measurements of radiation levels - the first held on the surface of another planet - can cheer those who want to see how once on Mars for the first time set foot on the person: Curiosity rover found that people may well spend some time on the surface of the Red Planet.

Curiosity rover sent to Earth a self-portrait

Curiosity, which is already three months traveling on the Red Planet, sent to Earth is a typical tourist photo - self-portrait in a landscape. There you can see the Martian sky, sandy valley and the mountain range of the crater Gale. The question is - who is shooting?

Mystery of the fourth planet

The Soviet space station...

Mars is on the border of the so-called "habitable zone" - the climatic conditions on the planet Earth is much harder, but still acceptable for organic life forms. Summer on the equator at noon the temperature is +20 ° C, the long winter it can drop below minus 140 ° C - twice colder very middle of winter in Antarctica.

Curiosity found Martian river on mars

New NASA rover Curiosity discovered that, most probably, is the bed of a dried-up Martian flow indicating that the surface of the Red Planet once flowed a stream depth of about a meter.

Photos taken by the rover, found in layers of rock outcrops large, rounded stones. Their shape suggests that the stones were transferred water on the planet's surface over long distances.

MARS AND SATURN

The planet Saturn, with details could hardly see our eyes. You can see the Cassini Division separating the rings as well as details of its turbulent surface. Date: April 6, 2012. (Credit: Fernando Silva.)

The red planet is revealed in detail for the CCD camera Fernando Silva. The polluted skies over the city of Santiago de Chile are not an obstacle for the astrophotography captures the details of the Martian surface.

Using a telescope Celestron Nexstar 127 SLT, a Maksutov-Cassegrain with focal radius of 12, ideal for capturing planets and planetary camera of the same brand Reimage, Silva took videos of these objects with little exposure to then add several frames in register.
