NASA’s Juno probe has been discovering more about Jupiter Internal Structure than ever before. It is about its internal structure. The $1.1 billion spacecraft, which arrived in orbit around Jupiter in 2016, has been studying variations in the gas giant’s gravitational pull. The probe’s latest discoveries point out that Jupiter’s wind-sculpted bands extend down over 3,000km. That’s on a planet which is 140,000km wide. “This solves a long-time mystery,” said Juno scientist Tristan Guillot. According to him that was all really important for understanding atmospheric dynamics, not just on Jupiter but on other gaseous planets like Saturn, Uranus and Neptune and also the exoplanets they were at that moment discovering.View More New Discoveries about Jupiter Internal Structure
The European Space Agency (ESA) has reported a new re-entry forecast for China’s Tiangong-1 space lab. It is supposed that the 8,5-ton spacecraft may fall into Earth’s atmosphere between March 24 and April 19, although European Space Agency officials stressed that this is a rough estimate. “Re-entry will take place anywhere between 43 degrees north and 43 degrees south such as Spain, France, Portugal, Greece, etc.View More China’s Big Spacecraft May Fall into Earth this Month
The Soyuz MS-02 spacecraft parachutes down to Earth on April 10, 2017 with 3 members of Expedition 50 on beard. On Tuesday February 27, 3 Expedition 54 crewmembers came back from the International Space Station in the Soyuz MS-06 spacecraft. They came back to Earth yesterday after spending 168 days abroad the International Space Station(ISS). NASA astronauts Joe Acaba and Mark Vande Hei and Russian cosmonaut departed the ISS at 6:00.View More 3 Space Station Crewmembers Came Back to Earth
NASA develops a moon rover for search and analysis water and other materials taken in a trap of ices on poles of the Moon and demonstration of how water can be made on a place. Flight is planned for November 2017, mission received the name Regolith and Environment Science and Oxygen and Lunar Volatile Extraction (RESOLVE) and will have a week for achievement of the purposes. To be enclosed the squeezed budget of $250 million (into the sum includes the rocket to the Moon) the project managers plan to use solar energy for a food of systems of a moon rover and scientific tools. However in places, where there can be water and other flying substances, the sunlight appears time in some days. For the value of this mission, it is necessary to use nuclear power. According to the scientists the solar batteries of mission are more available and such way they will try to go. It gives the scientist the long list of affairs and very a short time.View More New moon rover for finding the liquid water on the Moon
The American scientists suggest “to withdraw from resignation” the ISEE-3 space probe started more than 30 years ago, and to return it to research work. The ISEE-3 probe was one of three probes intended for research of solar and terrestrial communications, influence of a solar wind on a magnetosphere and near-earth space. Two others worked at Earth orbit, and ISEE-3 became the first artificial object output in a point Lagrange of L1 of Sun- Earth system, at 1,5 million kilometers distance towards the Sun.
In 1982 began the second life of the probe — it received the new name International Cometary Explorer (ICE), was put to heliocentric orbit and went on interception of a comet. In September, 1985 the probe successfully passed through a comet, then he participated in the project on comet research Gallia. But in May 1997, the mission of a space probe was officially stopped. In August 2014, the space probe ISEE will return to Earth. The scientists note, that at rather small investments it is possible to receive the big return comparable to results of start of a new research vehicle.
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.View More According to the Mercury Messenger spacecraft the green rock is from the 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.View More Disagreement Regarding the Location of NASAs’ Spacecraft Voyager 1
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.View More Spacecraft Vojager 1 is Outside of the Heliosphere
