Mars radation

High radiation on Mars surface

The Mars rover Curiosity helped the American scientists to find out that travelers to Mars will absorb lethal dose of the radiation, over 1 sievert of ionizing radiation, which indicates the need of installation of special “shelters” onboard of spaceships. By the words of scientists, they found that astronauts will absorb about 1,8 millisieverts of radiation a day during flight. The general dose during flight to Mars and Earth will make 0,66 sieverts, and together with stay on a Mars surface, can reach one sievert. Such quantity of radiation approaches to a radiation limit for astronauts during their career. The scientists came to such conclusion, having analyzed the data collected by the RAD device onboard a mars rover of Curiosity during its travel to Mars. This tool was switched on in Earth orbit in November, 2011. It is practically in the rover center that allowed to use it as model of the astronaut during flight to the Red planet.

Ancient water keeps secrets

Ancient water keeps secrets of life on Earth and Mars

Finding of sources of ancient water will help scientists to answer fundamental questions of emergence of life on Earth. The international team of scientists from Great Britain and Canada opened ancient deposits of the water, which age is estimated approximately at 1,5-2 billion years. This water was completely isolated from waters of the World Ocean and covered deeply underground. Interestingly that this water contains many all set of the chemical elements necessary for emergence of life. Scientists assume that the water found by them can be the most ancient on the earth and contain traces of any forms of life. Detailed research of this water will help scientists to learn how microbe life can arise and exist in isolation. Researchers from Manchester, Lancaster, Toronto and Makmaster found the most ancient water on a planet in mines in Ontario (Canada) at a depth of 2,4 kilometers by means of the most advanced equipment provided by University of Manchester.

Martian mountains

Mountains on Mars are created by a wind

Scientists came to a conclusion that Winds on Mars influenced its landscape more, than water. According to researches of the American Mars rovers and the European prospecting probes, the mountain on Mars has very peculiar form. Proceeding from all obtained data, after their careful analysis, scientists came to a conclusion that at all water, and a strong wind created mountains on Mars. Many scientists assume that the 5,5-kilometer mountain Sharp was also formed by numerous and powerful Martian winds. The group of scientists of Princeton University and the Californian institute of technology showed that formation of the mountain Sharp probably happened on the following mechanism: in the afternoon the air heated by the Sun, rose from a crater bottom, and by the evening process of return of air masses was observed back.

Arima twins craters on Mars surface

Mars craters the reason of underground explosions

The underground explosions are the reason for craters on Mars The underground explosions, which are involving ice, are responsible for two craters on Mars. The Mars twin craters are in the Thaumasia Planum, which is near to the largest canyon in the Solar System. The name of northern crater is Arima, but the southern crater has no name. The two craters have 50 km wide and show intricate interior features. The central pit craters are common on Mars, such as on the icy moons orbiting the planets in the Solar System. In this article I’ll explain the process, how the craters formed.

New data from Curiosity-How Martian atmosphere was disappeared

Curiosity’s information confirmed a hypothesis of reduction of amount of light gases in the atmosphere of Mars. There was found the most reasonable confirmation of gradual disappearance of the atmosphere of a planet. Results of research confirmed, that light gases disappeared from the top layers of the Martian atmosphere. For process of research of disappearance of the atmosphere the scientists analysed its structure. As a subject of studying isotopes of gas of argon were chosen. Now in the tmosphere of Mars is four times lighter argon-36, than heavy argon-38. It is much lower, than initial indicators for planets of Solar system. Such results allowed drawing a conclusion that gas disappeared from the atmosphere. First the planet lost easier isotopes.

Sandbot

SandBot – the Robot for navigation in the sand of Mars

As you know, the Mars rover named Spirit died four years ago in the Red planet. Its aluminum wheels sank in a sandy trap. Spirit landed on Mars in January 2004. Its last signal was six years later. The first sign that the Mars could have been a violent place was created by the Spirit. For future the robotic legs of this rover gives the physicist the new idea for creating the new Martian rovers. The physicist from UC Berkeley research lab Chen Li, combined a robot, which has six legs and can run in a bed of sand faster than any Martian spacecraft. The robot named by SandBot may help the experts of robots, to create more “terradynamic” robots, which can more closely mimic the way today’s animals move on the ground.

TGO and EDM for ExoMars Mission

TGO and EDM for ExoMars Mission

For the determination the existing the life on Mars, the European Space Agency (EAS) and Russian federal agency signed a contract. This contract allows them to work together on the ExoMars program. The EAS agreed to provide the Trace Gas orbiter (TGO) and the Entry, Descent and Landing Demonstrator Module (EDM) in 2016, and the rover in 2018. The Russian part agreed to be responsible for both missions. Two partners will supply all the scientific instruments and will closely cooperate. By the TGO the researchers will search the presence of methane and other gases on the atmosphere of Mars. Also the TGO will collect information for the 2018 mission. The EDM will lend on Mars in 2016 and will support the key technologies for the mission of rover in 2018.

The Martian Surface

Studying of the Martian Surface proves the version about the life in the Ancient Mars

The results of observation the rock, which was drilled from the Martian surface, the scientists announced that the conditions of Mars may have been suitable for human life. As you remember, several weeks ago the rover Curiosity drilled to the Martian surface and took materials from the underneath from the Martian surface. From the pictures, which the Curiosity had sampled, the scientists decided, that if there were an organic material in the Mars, it could be preserved. Also, the scientists find such components as carbon, sulfur, nitrogen, oxygen, phosphorus. These elements are basic elements for life in the Earth During the examination of the chemical components of the minerals from the Mars, the scientists discovered oxidized and reduced forms of sulfur compounds. That fact proves, that there was an energy gradient in the Ancient Mars. During next months and years, the rover Curiosity will continue to look for suitable areas and materials in the other parts of the Martian surface, because the scientists have a mission to find life in the Ancient Mars.

buried channels under the Surface of Mars

The Researchers found Mars Buried Channels

The Researchers who observing the surface of Mars saw the first 3D view of the channels, which were buried under the surface. The discovery shows that an underground channel is twice deeper than the scientists thought, and this fact is accepts as a water shape in the surface of Mars. The researchers think, that the surface of Mars has been barren for the past 2,5 billion years, as the Mars today is dry and cold, because the most part of its water is an ice caps. But the channels, which are in the surface, hint that the Red Planet’s surface once was flooded by the water. The largest from the Mars channels, which engraved within the past 500 million years, belong to the Marte Vallis system. Marte Vallis is in the Elysium Planitia, which is the youngest volcanic region of the Mars, and the volcanism covered the most part of the surface with lava during the past several hundred million years. Because of this, all the new information regarding its history, were buried under the lava. Using the radar researchers scanned the surface of the Elysium Planitia. The 3D reconstructions of Marte Vallis, showed many details, under the lava covering. But this shows that the Marte Vallis channels were deep approximately 230 feet (which is twice deep than the researchers thought).
