NASA and partners will simulate a potentially deadly asteroid strike this week

Think that it’s only Hollywood filmmakers who speculate about what would happen if Earth was ever struck by an errant asteroid? Think again! This week, NASA’s Planetary Defense Coordination Office (PDCO), the Federal Emergency Management Agency (FEMA), International Asteroid Warning Network (IAWN), and assorted other top international agencies are bringing together their sharpest minds to help figure out how Earth would prepare for the potentially devastating worst case scenario that is an asteroid strike.

Taking place throughout this week, the International Academy of Astronautics Planetary Defense Conference will play out a tabletop scenario in which a “Potentially Hazardous Asteroid” is discovered by astronomers in the sky. With an average size that could range from 100-300 meters, the asteroid is first considered to have a 1 in 50,000 chance of colliding with Earth (in the vicinity of 0.002%), which later rises to a 1 in 100 probability of impact. The conference, which sounds like the world’s most terrifying team-building event, is intended to examine what would happen next.

This is not the first time such an event has been held. Approximately every two years, asteroid experts come together to play out similar scenarios, intended to explore the best way to proceed should such an apocalyptic end-game situation actually threaten Earth. However, 2019 represents the first year in which proceedings will be shared in real-time using social media. To follow along, you can check out the @esaoperations Twitter channel and catch updates on Facebook. (Considering how the Twitter universe freaks out whenever a new episode of Game of Thrones comes out, we don’t want to imagine what it would be like if an asteroid really was on its way to wipe out humankind!)

“These exercises have really helped us in the planetary defense community to understand what our colleagues on the disaster management side need to know,” said Lindley Johnson, NASA’s Planetary Defense Officer, in a statement. “This exercise will help us develop more effective communications with each other and with our governments.”

Fortunately, as the press release stresses, “Although realistic, [this scenario] is completely fictional and does not describe an actual asteroid impact.” So don’t start building your asteroid-proof underground bunker and writing your boss a long letter revealing exactly what you think of them just yet.

How to watch NASA launch its DART anti-asteroid spacecraft tonight

NASA is about to launch a spacecraft with a daring mission: To crash into an asteroid, in order to test our planetary defense options. The mission, dubbed DART (Double Asteroid Redirection Test), will head toward a pair of asteroids called Didymos and Dimorphos and will crash into the smaller one in an attempt to knock it off-course. Don't worry -- the asteroid pair doesn't actually threaten Earth -- but this test will demonstrate what defense options Earth might have if an incoming body threatened our planet.

NASA gears up to launch a spacecraft that will crash into an asteroid

Most space missions don't intend to crash their spacecraft. But that's just what NASA has in mind for its upcoming Double Asteroid Redirection Test (DART) mission, when it will smash a spacecraft into an asteroid to see if that's a viable way to protect Earth from potentially dangerous asteroid impacts. The agency is preparing for the launch of the mission later this month.

While the large majority of asteroids that we spot whip harmlessly past Earth, a small number are termed "Potentially Hazardous Objects" which could impact the planet. With developments in technology, we're getting better at spotting these potential threats. But what do we do if we spot a chunk of rock headed for our planet? The DART project is a test of a planetary defense concept that involves crashing a craft into an asteroid.

NASA investigating possible issue with Lucy spacecraft hours after launch
At 24 feet (7.3 meters) across each, Lucy’s two solar panels underwent initial deployment tests in January 2021. In this photo, a technician at Lockheed Martin Space in Denver, Colorado, inspects one of Lucy’s arrays during its first deployment. These massive solar arrays will power the Lucy spacecraft throughout its entire 4-billion-mile, 12-year journey through space as it heads out to explore Jupiter’s elusive Trojan asteroids

NASA says its engineers are currently investigating a potential issue with its Lucy spacecraft where one of its solar arrays may have failed to lock into place.

Lucy launched aboard a United Launch Alliance Atlas V rocket from Cape Canaveral in Florida on Saturday, October 16.
