On Monday, NASA's Double Asteroid Redirection Test mission will attempt to crash its spaceship with a tiny asteroid.
The asteroid that Antares seeks is known as Didymos. It orbits the nearby moonlet Dimorphos.
Although the asteroid poses no threat to Earth, this expedition will put technology to the test that could be utilised to protect our planet from asteroid collisions.
NASA's ambitious mission is conceived and led by the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland.
The DART spacecraft, which will be launched on November 23, 2021, will be 6.8 million miles from Earth when it impacts Dimorphos.
To make conditions even more difficult, the spaceship will be approaching the space rock at a rate of nearly 4 miles per second.
It is not necessary for the DART mission to be successful because it is a test that may assist the scientific community.
