Marsbee is a robotic flapping wing flyers. Its size is as the same as bumblebee size with cicada sized wings. The Marsbee is combined with sensors and wireless communication devices. The mobile base can act as a recharging station and main communication center. Why NASA wants to send Marsbee to the Red Planet. NASA explains:
“The objective of the proposed work is to increase the set of possible exploration and science missions on Mars by investigating the feasibility of flapping wing aerospace architectures in a Martian environment. The proposed architecture consists of a Mars rover that serves as a mobile base and a swarm of Marsbees.”
A research of the most mysterious planet which stores for us a set of riddles proceeds. Recently from Mars comes the most unexpected news, regarding the secret of Mars. Mars Curiosity rover managed to find out strong evidences of that once far back in the past the Red planet could be quite suitable for life. According to results of research by the American space agency (NASA), careful analyses of the atmosphere of Mars show that this planet not strongly differed more than 4 billion years ago from Earth. During an era about which researchers speak, the atmosphere of Mars was much denser, and a planet surface – warm and damp. Mars Curiosity rover helped scientists to specify chemical and isotope composition of the Martian atmosphere, and also to find out hints that the most part of air of Mars disappeared in space about 4 billion years ago.
The Mars rover Opportunity confirmed the discovery made before Curiosity. It found proofs that in the ancient time there was water on Mars, which is suitable for live organisms. Earlier data from automatic probes testified that Martian water differed extreme high salinity and acidity. In March Curiosity mars rover obtained the evidence that Martian environment in the ancient time was suitable for life. In particular, that water on Mars was almost fresh and neutral. Now results of work of the Curiosity rover confirmed this find. Mars rover Opportunity studied a chemical composition of a stone to which the scientists appropriated Esperance 6 designation. They fix a ratio of aluminum, potassium, calcium and sodium, and also iron in clay breed in cracks of the stone. This clay could be formed only in the presence of a large amount of water.
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.
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.
The Mars rover Curiosity again started its full scientific researches on a surface of Red Planet. Even, the Curiosity rover made a fence of new samples of Martian soil and turned it into powder by scientific tools. Curiosity carries a pair of main computers. Each of these computers, (A-side and B-side) also has other subsystems. Now Curiosity is operating in B-side, and the A-side is a backup. One aspect of activities after switching to the B-side computer will check the six engineering cameras. The science instruments of the rover, including the cameras, can operate by either the A-side or B-side computer, whichever is active. Now the Mars rover Curiosity is ready to carry out the full chemical and spectral analysis of the received powder and to send results to Earth to Laboratory of Jet Movement (NASA).
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.
The Mars rover Curiosity of NASA, switched off, to wait out a Mars-bound solar blast. The mars rover will be put on standby after the Tuesday, when the SUN unleashed a flare in the direction of Red Planet. The team of rover views the shutdown of Curiosity, for withstanding of solar outbursts. The move can delay the return of mars rover to the operation, which is anticipated in this weekend. The robot perfectly operated in the Red Planet until Feb. 27, when it didn’t send the recorded data to the Earth.
NASA has narrowed the target for its most advanced Mars rover, Curiosity, which will land on the Red Planet in August. The car-sized rover will arrive closer to its ultimate destination for science operations, but also closer to the foot of a mountain slope that poses a landing hazard. It was possible to adjust landing plans because of increased confidence in precision landing technology aboard the Mars Science Laboratory spacecraft, which is carrying the Curiosity rover.
