NASA said on Monday that its mission to deflect an asteroid in deep space using a spacecraft is targeting a late November launch.

Known as the Double Asteroid Redirection Test (DART) mission, the U.S. space agency will send the DART spacecraft to a pair of asteroids – the Didymos binary – at 1:20 a.m. EST on November 24 aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California.

DART will smash in one of the two asteroids, known as Didymoon, at roughly 13,500mph on October 2, 2022.

In doing so, it will change the speed of Didymoon a fraction of a percent, but it will be enough so NASA can measure its altered orbit.

This will provide valuable input into future missions to deflect asteroids.

At roughly 160 meters (524ft) wide, Didymoon orbits a much larger space rock known as Didymos that is approximately 780 meters (2,559ft) across.

Didymoon came relatively close to Earth in 2003, coming within 3.7 million miles.

Of the two asteroids, Didymoon is more likely to hit Earth, given there are more space rocks its size that NASA and the Center for Near-Earth Object Studies (CNEOS) have yet to observe.

‘DART will be the first demonstration of the kinetic impactor technique, which involves sending one or more large, high-speed spacecraft into the path of an asteroid in space to change its motion,’ NASA said in a statement

NASA considers any near-Earth object as ‘potentially hazardous’ if it comes within 0.05 astronomical units (4.6 million miles) and measures more than 460 feet in diameter.

According to the U.S. space agency, there are just over 25,000 NEOs, but many more are waiting to be discovered.    

On October 1, NASA said that the cube satellite (CubeSat) that will accompany DART was ready for installation.

The CubeSat weighs 31 pounds and measures ‘roughly the length of an adult’s hand and forearm,’ the agency said

DART is the first part of NASA’s asteroid defense strategy, designed in collaboration with the European Space Agency to protect Earth from a possible impact from a ‘hazardous asteroid.’

‘Planetary defense is really about the present solar system and what are we going to do in the present,’ Dr Nancy Chabot, project scientist for DART, previously told

‘DART is not the final answer but rather just the first important step if we needed to defend the Earth from an asteroid impact.

‘Finding the asteroids that pose potential impact risks to Earth, tracking them, and characterizing them are critically important to all planetary defense efforts.’ 

The mission is being managed by NASA’s Planetary Defense Coordination Office and the Science Mission Directorate’s Planetary Science Division at NASA headquarters. 

In August, a study from researchers in California said that several bumps would be needed to change the course of an asteroid, such as Bennu.

NASA has previously said that Bennu has a one in 1,750 chance of hitting Earth in the next 300 years.
