The scientists of NASA will investigate asteroids directly in the space with the Orion spacecraft
The scientists of NASA develop the robotic Orion spacecraft. The purpose of this project is to capture of space object for in-depth studies. When falling to Earth any meteorite or an asteroid loses part of weight, burning down in the atmosphere, many chemical and physical properties of combustible object thus change.
If to study an asteroid directly in the space, for the scientists of NASA it will be possible to understand, what its real chemical composition. But The scientists of NASA will not just operate the Orion, because for Orion’s successful operation on connection of the spacecraft to an asteroid requires the help of the Moon. Orion will have to fly up to object, to capture him and to put to Lunar orbit.
The pilotless ship will grab an asteroid of 7,6 meters in size and of 450 metric tons in 2019. After that, the Orion delivers to it 4 astronauts, who will land on it and will study in 2021.
The meteorite scientist Anthony Irving think, that the green rock, which had been found in Marocco last year, may be the first visitor from the innermost planet of our solar system. According to the study the rock, which name is NWA 7325, came from the Mercury. NWA 7325 is a group of 35 meteorite samples. The age of those meteorites is near to 4.56 billion years. The scientist thought that the impact was shot out the NWA 7325 from Mercury to Earth. The scientist Irving is has been studying meteorites for many years, but the NWA 7325 meteorite is unlike any meteorite which had been found before. The Mars meteorites are imbued with Martian atmosphere, which makes them simple in difference to the other rocks. Containing rocks of Vesta, as well as chemically, and the meteorite NWA 7325 different from any of space rock watched the scientists of today. It is the first meteorite from all meteorites, which the scientists observed, which has low intensity. The magnetism passed from a cosmic magnetic field into a rock. So the scientists think that the rock formed as “scum” on the top of the magma. .The geological and chemical composition of the Mercury is familiar to the scientists, and they think, that the surface of Mercury is low in iron. The meteorite is also low in iron. This fact allows the scientists to suggest the version, that the parent body of meteorite is Mercury.
Though, the American Geophysical Union reported that the spacecraft Voyager 1 was outside the heliosphere,but the NASA don’t agree with this report. By the words of team of Voyager 1, the spacecraft has not left the solar system yet, or it reached to interstellar space. The AGU, did the measurement at AUG. 25. These measurements showed radical changes, which meant that the spacecraft had left the solar system, or the huge magnetic bubble including our solar system, and the entire magnetic field. There is some disagreement between the astronomer Bill Webber (professor from New Mexico State University in Las Cruces) and the Voyager project scientist Ed Stone regarding the location of Voyager 1. Bill Webber explained, that during a few days decreased the intensity of heliospheric radiation, and the cosmic ray intensity went up. But Ed Stone explained that the spacecraft had reached to a new region, named “the magnetic highway”, where changed the energetic particles.
The spacecraft of NASA Voyager 1, is the most far object from the Earth. The Voyager 1 is the fastest spacecraft, which the people have ever created. In 35 years after start an automatic probe “Voyager-1” recorded strong change in intensity of quickly moving loaded particles called by space beams, which allowed to draw a conclusion of the device, which could cross heliosphere border. The heliosphere is a solar systems’ border. Beyond the limits of interstellar space, there must be parts, which will be independent from the loaded parts and from a magnetic field . The scientist Bill Vebber think, that everything speaks well that the Voyager-1 left the region depending on influence of the sun, its data show such characteristics of hydrogen and helium which can be observed in the interstellar environment.
The Russian spacecraft named “Soyuz” safety arrived to Kazakhstan. There were 3 man in this spacecraft, one of them was from USA, the others were from Russia. This group of astronomers had a mission in International Space Station, and has spent there about five months. It was the crew of the 34rd expedition of ISS. The Russian spacecraft “Soyuz” made landing in a regular mode on March 16 at about 11:11 p.m. According to the physicians, all crew members feel well. During the stay onboard the International Space Station, crew members participated in performance of 50 important scientific experiments according to the Russian program of scientific applied researches and experiments.
Last Saturday on March 9, the Cassini (Cassini is a NASAs’ robotic spacecraft sent to the Saturn planet) was most near to the Saturn moon Rhea , for the first time. During this close passing the Cassini did the image of the Rhea. The purpose of flyby was to observe the internal structure of the Rhea. This probe was done by measuring the gravitation pull of Rhea. The results of probe will help the scientists to find out if the Rhea, which has 950 mile wide, is homogeneous, or it is separated into core layers of mental. The distance of Cassini from the Saturn moon Rhea was 997 kilometers, and from this distance it was possible to capture the terrain of the Moon. The Rhea is the second largest moons of Saturn among the 62 moons. It has a surface with a lot of ice and craters. In the composing of Rhea is including rocks and water ice. The researchers also searched the dust flying off the moon, which will determine the micrometeorites’ impacts rate on the surface of the Rhea.
The Dragon Capsule is preparing to do the first operation, from dozen missions for Nasa. The time of launch is 8:35 p.m. on Oct. 7 from Florida Station. The spacecraft will join with International Space Station after three days. The flight, named CRS -1, will begin and do the same rendezvous with the station, as the previous craft. The Dragon capsule will go to space, on 9 rocket and 9 kerosene- and oxygen-powered engines. When the Dragon capsule is in orbit, after eleven minutes, a controllers will begin the testing of rendezvous’ sensors from the Earth. The SpaceX craft will spend about three weeks, then the craft will return to the Earth. The difference of this mission from the previous, is that the Dragon capsule will be filled by the cargo for an operational mission. In the capsule will be the freezer for the station’s samples, and the locker, which will be filled by variety materials, for those astronomers, who lives and works in the station.
NASA’s Cassini spacecraft has delivered view of Saturn, taken while the spacecraft was in Saturn’s shadow. The cameras were turned toward Saturn and the sun so that the planet and rings are backlit. This special, very-high-phase viewing geometry lets scientists study ring and atmosphere phenomena not easily seen at a lower phase. Since images like this can only be taken while the sun is behind the planet, this beautiful view is all the more precious for its rarity. The last time Cassini captured a view like this was in Sept. 2006, when it captured a mosaic processed to look like natural color.
NASA’s NuSTAR mission (a mission to search for black holes in the universe.) is scheduled to launch from Kwajalein Atoll in the central Pacific Ocean on June 13, no earlier than 8:30 a.m. PDT (11:30 a.m. EDT). The observatory, which will hunt for black holes and other exotic objects using specialized X-ray eyes, will be launched from a Pegasus XL rocket carried by an Orbital Science Corporation L-1011 “Stargazer” plane. The plane will take off from Kwajalein Atoll an hour before launch, flying out over the Pacific Ocean.
