Here's how NASA develops asteroid samples on earth

"We're looking for something on the beach shore along the walls, without any big obstruction or big bells," said Eteel Church, deputy Lahide Martín, under the command of the Cosmic Army called the Touch and Go Sample Acquisition Mechanism.

The ideal landing area will have a minimum of 25 meters (82 feet) radius in the clear zone and the rocks are no more than two centimeters (0.7 inches) in diameter.

"We need a pretty big TAGSAM site because we do not know exactly where we are going to land and we need to have rocks that is the right size for the sample," the Church explained in an interview with Seeker.

When the time is right, the spacecraft will become his approach to Bennu by hand. As the arm is on the surface, the nitrogen gas mechanism leaves the fire. The dust should rely on the "chapter" that is attached to the arm. Arm includes a pogo-stick mechanism that will push the spacecraft away from Bennu quickly, as well as floating astronauts use their arms or legs to push away the wall.

The spacecraft will perform before closing the patterns and moving back to the Earth, and before arriving in 2023. This is a small difference in how the Japanese Hayabusa2 Isotka 2020 is asteroid material. Use the selection hinge, which then takes out the material that covers the spacecraft in the particles to activate the particle.

True, the role of TAGSAM does not take place over a few years, the church team wants to make sure that the arm is ready. At the end of October, it was successfully trying to move the weapons in the first space. The next big step is scheduled on Wednesday (Nov. 14), when the arm's full capacity is motion and visualization will be tested.

The church called the test "a very important and exciting stage for Lukayette Martin". Of course, if the arm is planned, it will be an important step for NASA. This mission will be the first time the agency will have a sample of its asteroid sample on Earth.
