NASA asks for help from the Internet community in the mission, OSIRIS-REx
Source:Scientists from space Agency NASA has decided to appeal to space enthusiasts, with a request for assistance in the detailed mapping of the surface of the asteroid Bennu. The Agency's experts want the users of the Internet helped them to celebrate on a special map all the stones available on the surface of the object so that later you can choose the most suitable point for collection of soil samples of an asteroid, according to the portal Space.com.
The Source said that experts from NASA will be six weeks from the time when the space research unit of the OSIRIS-REx located on the orbit of the asteroid Bennu, will complete the task of drawing up a detailed picture of the surface of the object, until the moment when you will need to finally determine the location of soil sampling from its surface. At all desire, the number of people that was dedicated to this mission, not nearly enough to tackle the task of drawing up detailed maps of the surface features of the asteroid.
"the Task is to map each boulder on the asteroid's surface is really big, and we really found no other way to do it is available a period of time," — explains to the participant of the project of Karina Bennett.
"We really do need help from outside" — adds the scientist.
A Detailed map of the boulders of the asteroid Bennu, scientists needed to in the process of collection of soil samples not to damage the robotic arm, equipped with a special pneumatic device. If you know the exact location of the stones, scientists will be able to choose the most optimal location to reduce staff and planned operations. The problem is complicated by the fact that the surface of Bennu was much rougher than the researchers originally anticipated.
"it's a lot more rocks and boulders than we expected," — explains Bennett.
High Quality the surface of the asteroid, NASA experts are going to publish on a special website in late April – early may. From this point on will begin a six-week report, for which space enthusiasts will have to look carefully at the image, noting the boundaries of the boulders on the surface of the object.
"I Think the most interesting component of this work will be that you will actually be able to contribute to the adoption of subsequent decisions. You can then see how we will take the sample, and may see the same area where you yourself noted the boulders", — said Bennett.
The spacecraft OSIRIS-REx is designed to study asteroid Bennu and the collection of soil samples from its surface, was launched in September 2016. The device is equipped with several science instruments including cameras, spectrometers and a laser altimeter. At the end of December 2018, OSIRIS-REx entered the orbit of the asteroid, and is currently waiting for the next stage of the mission – in fact, collecting samples of soil from its surface.
The Surgery is scheduled for mid 2020. It will hold with a special manipulator with pneumatic mechanism. The mission team expects to receive a total of 60 grams to 2 kilograms of soil samples. To return the unit to home is planned in the autumn of 2023. The samples were placed in a special capsule will be dropped on the ground.
The Asteroid Bennu has a diameter of about 550 meters. He belongs to the group of Apollo objects whose orbit crosses the Earth's orbit. According to rough estimates, the probability of collision of Bennu with the Earth is 1 in 4000. In case it is really falling on our planet, the energy released when you drop a body on a surface, the power will be equivalent to the explosion of a bomb with a capacity of 2700 megatons.
