The small comet P/2010 A2 (LINEAR) has characteristics at the same time an asteroid and a comet. For the first time this asteroid was open on January 6, 2010. When this asteroid was in the main asteroid belt, astronomers noticed at it a tail, as at a comet. For this reason initially this asteroid was entered in the catalog as a comet of the main asteroid belt.
About 1 month astronomers observed the object P/2010 A2 (LINEAR) with help of Hubble telescope. After one month the astronomers came to conclusion that it is not a comet with a tail from parts of ice, but an asteroid with a tail from a dust and the gas, formed after collision with any other space object.View More Astronomers captured the tailed asteroid P/2010 A2 (LINEAR)
If the dangerous asteroid departs towards to Earth, one of options will be sending the spaceship, which will destroy it a nuclear bomb.
Such mission which will cost about $1 billion can be developed in NASA, for protection against asteroids. Bong Wie, the director of the Research center at university of the State of Iowa, described system which develops it team, for visitors at the International conference on space development in La-Hoya, California, on May 23.
The anti-asteroid spaceship delivers the nuclear bomb to destroy threats before they will be able to reach Earth. The two-section spaceship will consist of an impact of kinetic energy, which will separate for crater creation in an asteroid. Other part of the spacecraft will bear the nuclear weapon, which will explode in an asteroid crater.
The purpose will consist in division of an asteroid into a set of parts, which then will disperse on separate trajectories.
Wie considers that 99 percent of parts of an asteroid will fly by Earth that considerably limits impact on a planet. What will overtake Earth, will burn down in the atmosphere and don’t pose any threat.View More A nuclear bomb can be the best protection of Earth from dangerous asteroids
Found new research, that twenty five percent of lunar craters can store the remains of asteroids, which created them. The surprising result allows to assume that it is necessary to scientists a little more difficult, than they expected to find out, from what the Moon consists. By the words of coauthor of research Jay Melosh from University of Pardyyu future researches of structure of the lunar soil should work to prove that breeds on a surface really lunar, instead of arose owing to falling of the asteroids, especially unusual or exotic minerals. Melosh and his colleagues used computer models for imitation of formation of lunar craters from collision with asteroids. They defined that one quarter of craters on the Moon were left the asteroids flying with a speed of 26 800 miles/h (43 130 km/h) or less – improbably quickly, but not quickly enough that the asteroid was destroyed. Other calculations executed by team, show that at such speeds the asteroid doesn’t evaporate, and many its parts remain in the formed crater. If diameter of a crater not less than 20 kilometers, the remains of an asteroid tend to collect in the central dive of a crater, gradually collapsing under the influence of gravitation of the Moon.View More In lunar craters remained splinters of ancient asteroid
At the end of the month the big asteroid will fly by the Earth. It will be the asteroid’s greatest rapprochement with our planet for the next two centuries. On May 31 the asteroid 1998 QE2, which diameter makes about 1,7 miles (2.7 km), will fly by the Earth and doesn’t pose threat. The space stone will fly by at distance of 3600000 miles (5800000 km) from our planet – in 15 times more distances between Earth and the Moon. Astronomers, who plan to consider 1998 QE2 with help of two huge telescopes, wait for uneasy the approach of asteroid. Every time when the asteroid comes nearer, it provides opportunity to scientists in details to study it to understand his sizes, a form, rotation, features of a surface. This information can tell us about its origin. Also we will calculate diameter of an asteroid and its speed with help of Goldstoun to improve the calculations of the orbit and to calculate future trajectory of asteroid movement.View More The huge asteroid 1998 QE2 will fly near the Earth on May 31
The asteroid 1999 RQ36 by the results of competition among school students received a new name Bennu, in honor of an Ancient Egyptian deity heron. The asteroid (101955) 1999 RQ36 of 500 meters in size opened by scientists from the LINEAR project of Massachusetts Institute of Technology. In 2182 it will approach to the Earth. After “cancellation” of threat of Apofis and some other asteroids, it became the main potentially dangerous object for the Earth. Participants of the OSIRIS-REx project, for receive a name, which will be easier to be said, than 1999 RQ36, declared competition on the best name, which participants could become school students from any country of the world, but more younger than 18 years. On competition arrived more than 8 thousand options from school students from 25 countries. As a result the Committee on names of small bodies of Solar system of the International astronomical union accepted the option offered by nine-year-old Michael Puzio from Northern Carolina. The American asteroid project OSIRIS-REx for the USA will be the first program of research of an asteroid with help of an automatic probe.View More Asteroid 1999 RQ36 which will approach to Earth in 2182 received new name Bennu
In NASA deny calculations of the Italian astronomer and claim, that the probability of collision of an asteroid with Earth is insignificant. After 13 years, in April 2026, the twenty-meter asteroid 2013 GM3 will fly by in only 8,5 thousand kilometers from a terrestrial surface. The calculations, which have been carried out by the Italian astronomer Francesco Manka from observatory of Sormano testify to it. For the first time the asteroid 2013 GM3 was found on April 3 of this year by the scientists working at the American observatory of “Maunt-Lemmon”. The laboratory of jet movement of NASA carried out calculations, which showed that on April 14 2026, at 13.30 across Greenwich this asteroid will fly by at distance of 39,7 thousand kilometers from Earth surface. However the Italian scientist conducted the researches: its calculations showed that appointment to heavenly “guest” can become “closer”.View More Asteroid 2013 GM3 will fly close to Earth in 2026
The head of NASA submitted the draft of the budget of agency for 2014. The total amount of the required budget of space agency for 2014 fiscal year makes 17,7 billion dollars. By the words of astronomers using available breakthrough technologies, NASA develops the first mission in the history on identification, capture and asteroid towage. This mission will bring research of a space and human knowledge to new level, will help the astronomers to protect a native planet and will approach them to sending people for an asteroid. The task of project is to take a small asteroid and to transfer it to a circumlunar orbit. Flight of astronauts on an asteroid then will be provided with help of NASA carrier rocket “System of space starts” (Space Launch System) and the Orion spacecraft. For a start, the probe, which will pursue and will take approximately 25-foot (8 meters) the asteroid, will be pilotless. It will receive a food from solar electric motors, which generate draft at the expense of acceleration of the loaded particles called by ions. Pilotless test start of Orion is planned for the next year.View More Methods NASA for catching asteroid
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 next three weeks will be critical for United States, as the asteroid may fall in the USA territories. The astronomer from the American Space Agency of NASA reported that there is a real threat of collision with huge object. The unknown asteroid was noticed on March 22 over east coast of the USA in the form of a big fiery sphere. From the moment of flight of this asteroid over the USA, in the American meteoric society arrived about 630 messages concerning this phenomenon. The 0,9-meter asteroid was called the Manhattan asteroid. According to its trajectory of flight, it can really pose serious threat for the USA, however scientists calm Americans that according to statistics the asteroid of the decent size hits the Earth about 1 time in 1 000 years. The astronomers think that the asteroid may change its own course by the time and void the hitting the Earth. Some of the astronomers think that the asteroid wouldn’t hit the Earth, because it is in the sky and passing the atmosphere the huge object may lose its fire. But, the other part of astronomers fear, that it will create a huge crash over the city of New York.View More NASA Reported United States Faced a Real Threat of an Asteroid Strike
