With NASA's DART asteroid deflection mission about to launch and a new movie asteroid disaster movie coming to Netflix, this question is hot on many people's minds. Now, a NASA scientist has weighed in on what the agency would do if there really was an asteroid about to collide with Earth.

The inner solar system is filled with space boulders that probably broke off of bigger bodies at some point.
A sneaky space rock sped by Antarctica on Sunday without any advance warning and narrowly avoided being fully incinerated by Earth's atmosphere.
Humanity's first asteroid defense mission launches in less than1 month | Space
NASA is less than one month away from launching humanity's first-ever asteroid-deflecting mission, known as DART, short for "Double Asteroid Redirection Test."
DART is a spacecraft that will launch in late November with the purpose of deflecting an asteroid. The craft will hit an asteroid head-on in an attempt to move it onto a slightly different path.
EarthSky | Asteroid Bennu's boulder mystery solved
Why does near-Earth asteroid Bennu have so many boulders on its surface? Prior to late 2018, when NASA’s visiting spacecraft OSIRIS-REx visited Bennu, scientists expected the asteroid to have a surface entirely or partly coated in a fine regolith of sand and pebbles.
The new study, published in the peer-reviewed journal Nature on October 6, 2021, comes from the University of Arizona. The study suggests that porous rocks are responsible for the lack of fine regolith on Bunnu’s surface.
Astro Bob: Biggest asteroid Ceres buzzes the Hyades | Duluth News Tribune
Giuseppe Piazzi at the Palermo (Italy) Observatory discovered Ceres on Jan. 1, 1801. At the time, it was dubbed a new planet. But when dozens more of these tiny bodies turned up over the coming years astronomers faced a dilemma.
William Herschel, discoverer of the planet Uranus, suggested calling them "asteroids," a word that means "star-like," after aster , the Latin word for star. Through telescopes of the era, Ceres and its ilk showed no discernable disks but instead looked exactly like the pinpoint stars.
Balky solar array still troubling NASA's Lucy asteroid probe | Space
Shortly after Lucy's Oct. 16 liftoff, mission team members determined that one of the spacecraft's two huge solar arrays had not fully deployed . Lucy's handlers have been working hard on the problem, but it remains unsolved at present.
"Analysis indicates that the array is between 75% and 95% deployed. It is currently being held in place by a lanyard, specifically designed to help unfurl the arrays during deployment," NASA officials wrote in an update on Wednesday afternoon (Oct. 27).

The US$981-million Lucy mission, which launched from Cape Canaveral, Florida, on 16 October, will spend the next 12 years performing gravitational gymnastics to swoop past six of the asteroids, known as Trojans, to snap photos and determine their compositions.
Rocks Ejected From Asteroid Bennu Can Reach Earth | Planetary News
NASA's Origins Spectral Interpretation Resource Identification Security-Regolith Explorer (OSIRIS-REx) spacecraft spent more than two years orbiting asteroid (101955) Bennu.
Robert Melikyan of the University of Arizona and colleagues simulated the paths traveled by particles ejected from Bennu to determine how many ejected particles would reach Earth and when.
The Week Unwrapped: martial lawlessness, asteroid action and statue sparring | The Week UK
A landmark study has found that London has more public sculptures of animals than it does of women or people of colour. The research, which is funded in part by City Hall, is part of a major project launched in the light of the global protests against racism and inequality last year.
