Happy International Asteroid Day! To celebrate the today, which I see as the younger but paradoxically more established version of Apophis Day, I'm sharing four videos Seeker posted during the past year about asteroids. The most recent, which was uploaded just yesterday, had Seeker ask If An Asteroid Was Heading For Earth, How Could We Stop it?
NASA and ESA have a unique plan to slam a spacecraft into an asteroid—here’s why.As I wrote in a comment at the video, "Perfect video for International Asteroid Day!"
Agencies around the world are working to bring samples of asteroids back to Earth, like NASA’s Osiris-Rex and JAXA’s Hayabusa-2, because bringing a piece back is like looking into a time capsule from the universe. BUT asteroids pose a serious threat to Earth. And ESA and NASA have a unique plan to combat that particular problem: they’re going to slam a spacecraft into an asteroid.
But asteroids also post a serious threat to Earth and so ESA and NASA formed a scientific collaboration known as the Asteroid Impact and Deflection Assessment, or AIDA, to combat this potential problem. The collab consists of two missions: NASA’s Double Asteroid Redirection Test, or DART, and ESA’s Hera Probe.
DART will smash into an asteroid in 2022 helping the AIDA mission study how effective a kinetic impactor would be in asteroid deflection and then four years later the Hera probe will arrive to do some assessments.
Seeker examined the mission eight months ago in NASA Plans to Slam a Spacecraft Into an Asteroid, which I'm including for completeness.
What if a deadly asteroid was on a collision course to Earth? NASA and the ESA have come up with a solution.As I have written many times about Apophis Day, it's when I observe the perils of space, particularly asteroids. Follow over the jump for the promise of asteroids.
Asteroids impacting Earth can be devastating—killing all the dinosaurs in existence level devastating. But even the asteroids that aren’t mass-extinction huge can be a serious threat.
Every few thousand years Earth (a.k.a. you and I) get hit with a massive asteroid the size of the Great Pyramid of Giza, so what is the plan when we get hit with the next asteroid?
We get hit with an asteroid about the size of the Great Pyramid of Giza every few thousand years, and when the next one hits it could cause massive damage to an entire region. So when we spot the next one coming, what’s the plan?
