NASA is planning a new mission to help us learn how to mine asteroids. The mission, called the Asteroid Redirect Mission (ARM), will launch in 2020 and will travel to a near-Earth asteroid called Bennu. Once there, the spacecraft will collect a sample of the asteroid and return it to Earth, where scientists will study it.

Asteroids are rocky objects that orbit the Sun. They are thought to contain valuable resources, such as metals and water. However, we don't yet know how to mine these resources. The ARM mission will help us test out new technologies that could be used to mine asteroids.

The ARM spacecraft will use a new solar electric propulsion system to travel to Bennu. This system uses solar panels to generate electricity, which is then used to power the spacecraft's ion engines. Ion engines are very efficient, and they will allow the spacecraft to travel a long distance without using much fuel.

Once the spacecraft arrives at Bennu, it will use a robotic arm to collect a sample of the asteroid. The sample will be placed in a capsule and returned to Earth. The capsule is expected to land in Utah in 2023.

Scientists will study the asteroid sample to learn more about its composition and structure. They will also test out new technologies that could be used to mine asteroids. The ARM mission is a major step forward in our efforts to learn how to mine asteroids.

Here are some key details about the ARM mission:

* The spacecraft will launch in 2020.

* The spacecraft will travel to a near-Earth asteroid called Bennu.

* The spacecraft will collect a sample of the asteroid and return it to Earth.

* The capsule is expected to land in Utah in 2023.

* Scientists will study the asteroid sample to learn more about its composition and structure.
