More recently, NASA announced its summary plan for 2016 – to send to the new automatic asteroid mission OSIRIS-REx.
OSIRIS-REx probe will hover above the asteroid and using the hand-arm to take soil samples from him and then bring them to Earth.
In world practice, this was accomplished only a few times, and in all cases it was a negligible amount of a substance that causes additional problems. After the Japanese and American efforts, this feat was decided NASA.
This mission is designed to get closer to the target designated by President Obama, to expand its activities beyond Earth orbit and to pave the way for manned missions into deep space further.
OSIRIS-REx project was selected among the only two other candidates, offering to take soil samples from the back side of the moon and the planet Venus.
In this context, the asteroid and is the most accessible and interesting to science, earth satellite sufficiently studied and poorly known earthlings against a difficult expedition to Venus, with its poisonous climate.
In other words, the asteroids are now more interesting than the Moon and more accessible than Venus. At one time they were formed from the same protoplanetary nebula, and we know that the planets in our solar system.
Do not have a life on its surface, asteroids are bodies “lifeless”, and therefore do not change, so keep your precious prints of pedigree. Often, this is why they are called “windows into the past,” returning us to the birthday during the solar system.
After the convergence of several kilometers, the probe for another six months will be very detailed three-dimensional map of its surface, scientists can only choose the most interesting parts of the fence and the ground will command the probe to a final rapprochement.
It is planned to collect a minimum of 50g of a substance that only 2023 will be delivered to Earth for study. OSIRIS-REx landing planned in the desert of Utah.
Information about the asteroid RQ36
NASA selected an object for research is not accidental. Has a diameter of RQ36 a little over a mile. He almost did not undergo major changes over billions of years of existence, and therefore should give a good “snapshot” of conditions in which he was born and the rest of the solar system. Scientists also believe that the RQ36 rich in carbon and therefore can expect to find on it and the simplest organic compounds.
Another objective of the mission OSIRIS-REx
Finally, scientists can directly measure the first known Yarkovsky effect. The effect is the appearance of a weak jet momentum resulting from the uneven heating of the asteroid’s weak rays of the star, enough to make on a large scale to have a significant effect on the orbits of asteroids. So far, the effect was only confirmed by the observations of ground-based observatories, but a more accurate measure of its value should be to clarify the existing formula for a “gem” predict trajectories of celestial bodies.
