Scientists recommend sailing the seas of Titan


The concept of a new mission to discover Saturn's largest moon is a machine capable of driving on the surface of Titan on the wheels, and then turn the boat and walk with blades and propeller on hydrocarbon seas second largest satellite solar system.

The mission of "Cassini-Hyuygens" Titan is actively studied in the 2000s, was able to stay a short time on the surface of its seas.

The new mission, called Titan Lake In-situ Sampling Propelled Explorer will land in the middle of the largest lake in Titan's called Sea Ligei will float to the coast, along the way making scientific measurements. The expedition will last from six months to a year.

Shock waves are concerned the solar system


The planets of our solar system could have formed at different times, with the participation of shock waves coming from the sun, according to an astronomer.

This theory presumes that the Earth is one of the youngest of the planets in the solar system, along with Mercury, Venus and Mars.

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.

Solve the mystery of the magnetic anomalies asteroid Oljato


Asteroid 2201 Oljato moving surrounded by the orbit of Venus shows a slightly extraordinary behavior. Past observations point to the associated magnetic phenomena, but new data from the unit Venus Express, show that the magnetic anomaly is suddenly no longer appear.

Team member mission Venus Express Dr. Christopher Russell explains the behavior of asteroid Oljato follows:

Vesta may be a tiny planet


Deep melancholy surrounding the asteroid Vesta, may indicate that the message has a complex structure, a characteristic not of asteroids, and to the planets, according to a new study.

Researchers led by Debra Butskovski (Debra Buczkowski) Applied Physics Laboratory of Johns Hopkins University in Laurel, Maryland, noted that grooves that extend to the surface of Vesta, are no cracks in the form of the letter V, which are usually formed on the surfaces of asteroids in the result their collision with other space objects, and so-called grabens - areas of the cortex, which fell on the level of the rest of the surface tectonic fault lines, so that the form of education closer to the letter U. 

Get the most accurate picture of Pluto, made with Earth


The planet, dwarf planet or Kuiper Belt objects, so what's the difference? The main thing that astronomers the most detailed picture to date of Pluto ever do with ground-based observations.

And that's how they got it:

They did a series of pictures of Pluto and Charon, using a newly developed camera called Differential Speckle Survey Instrument (DSSI), which is mounted on an 8-meter telescope of the Gemini North, located in Hawaii. 

Map of the route of the rover Curiosity in the first 43 days of sunshine on Mars ...


This map shows the route of the NASA rovers Curiosity in the first 43 Martian solar days (called solami) on the planet Mars (solar day on Mars is almost equal to the earth - 24 h 39 min) during the execution of the mission on Mars (September 19, 2012)...

The route starts from the contact with the surface of Mars rover, that is from the landing site, later known as the landing site Bradbury (in honor of the American science fiction writer Ray Bradbury, who passed away recently).
