The Japanese are preparing to launch the second asteroid expedition

60
JAXA, the Japan Aerospace Exploration Agency, announced the completion of the assembly of the Hayabusa-2 spacecraft, which is supposed to deliver soil samples from the asteroid. The launch of the launch vehicle is scheduled for the end of this year, the portal Science and life.

"Hayabusa-2" and a projectile-impactor (Figure).

This is the second attempt of the Japanese to deliver asteroid substances to the earth for their direct study. The first was undertaken in 2003. Then the Itokawa earth group asteroid became the object of study. The Hayabus-1 device was sent to it, which produced asteroid dust collection. The space operation was supposed to end in 2007, but due to technical problems that had arisen, the capsule with the alien substance could only be returned in the middle of 2010.

The goal of the current expedition is a near-earth asteroid (162173) 1999 JU3. It belongs to the Apollo group and has a shape close to spherical. The asteroid was discovered in 1999, but has no own name yet.

According to the researchers, "This carbon-rich small celestial body, belonging to the dark spectral class C, can contain in its rocky rocks both water and virgin organic matter belonging to the initial period of the solar system." This circumstance, according to planetologists, "could shed light on the evolution in the early stages of our solar system more than 4,5 billion years ago."

The diameter of the spherical block is almost a kilometer (about 0,92 km), which is twice the size of the previous object of study - the Itokawa asteroid.

“1999 JU3 moves in an elongated elliptical orbit at an average speed of approximately 27 km / s, crossing the orbits of the Earth and Mars. Its orbital period around the Sun is about 474 days, the period of its own rotation is 7, 63 hours. The inclination angle of its orbital plane to the ecliptic is more than 5,88 degrees, ”reports JAXA.

Experts have calculated that the most advantageous window for launching Hayabusa-2 falls on the end of 2014. If the launch for any reason fails, then the next favorable opportunity presents itself only in 10 years - in 2024.

According to the developers, the new spacecraft is in many ways similar to its predecessor, the Hayabus-1, but there are also differences in equipping it with a kind of gun, which will help to get samples of asteroid soil, and not only from the surface, but also deeper layers of this heavenly body. "

The agency said that when approaching a space object from the spacecraft "from a distance of 100 meters, an asteroid will be released at a speed of 2km / s metal projectile impactor, which will produce a small explosion on the surface of a celestial body." After that, soil samples (surface and surface) will be collected using a sliding device and placed in a special container, which must then be delivered to Earth by the device.

Probably, this will be the ground pick-up.

          If the asteroid’s orbit is calculated, then why break it by dividing it into pieces. And if it falls apart into several pieces, which will go in their orbits and where they will go, it is not yet possible to predict, only after division.

            Yes, no one thinks to crush an asteroid !!! Substance will be taken for analysis! When a metal blank strikes the surface of an asteroid, there will be a release of matter that will be captured by the space probe trap.

          In fact, the mission of the Japanese is quite unique, because the probe should not be brought closer to a large planet with its own gravitational field, but to an object with a diameter of only 1 km and moving at a speed of 27 km per second.

Even science fiction writers "scientists" until the 60s wrote that interplanetary flights are not possible, because do not catch up with the ground when returning (29 ...).

      Asteroids, in addition to studying the primacy of the universe, are interesting in that they may contain elements that are few on Earth. In Japan, they don’t get anything at all for the production of electronics, they buy everything. And it’s very interesting to know if there are any new elements or substances that are unknown on Earth. Their presence and extraction from asteroids will allow this country, perhaps, to make a breakthrough in science and technology and technology. It is also possible domination and control (through coercion) of the whole World.

The Japanese want to raise dust from the solid surface of the asteroid's body, and for this an artillery piece is completely unnecessary. And to change the orbit of that scanty "gun" (can be compared with firing a slingshot at a flying plane) is clearly not enough.

    It is possible that Japan is not telling anyone, but one of the goals of studying the terrestrial asteroids is to change their orbits and the direction of the trajectories of falling on certain countries. This is not a nuclear weapon; there are no prohibitions on it. The catastrophic consequences for the country on which the asteroid will fall are comparable to a massive nuclear attack, i.e. the country plunges into the stone age. And to prove that Japan has done this is very difficult, which means complete impunity. This will seem fantastic to some, but scientists around the world are already thinking about how to change the trajectory of especially dangerous asteroids (for example, Apophis) so that they fly past Earth.

    It was interesting to read about Hayabusu-1. Due to the solar flare during the flight, batteries were damaged, ion engines junk, gyroscopes failed. During an attempt to land on an asteroid, a computer crash occurred, as a result of which it lost a mini-robot and damaged one of the engines. Nevertheless, the mission as a whole was successfully completed. The world's first delivery of an asteroid substance to Earth. This one will probably have fewer surprises.

    On Hayabus-1, several bullets were used to shell an asteroid, or rather they tried to use. I understand that bullet shots should have pushed the apparatus in time, but since the shots did not happen, the apparatus collided with an asteroid.
