Get past the fake science, and the Taurid meteor shower foreshadows what could, one day, pose a troubling scenario.
Ramses, a European space mission to study the asteroid Apophis, has been approved for perparatory work.
In 2022, a probe was sent crashing into an asteroid as part of a “planetary defence” test. This Monday, the second part of the mission flies off to study the consequences of the impact.
Discovered less than a week ago, the truck-sized asteroid skimmed much closer to Earth’s surface than most satellites.
NASA has been gaining momentum in recent years as investment into space has ramped up in the US. In 2022, missions dealt with the farthest, closest, hottest and coldest conditions in the universe.
The Double Asteroid Redirection Test successfully showed that it is possible to crash a spacecraft into a small asteroid and change its orbit. This technique could save Earth from asteroids in the future.
The Double Asteroid Redirection Test successfully showed that it is possible to crash a spacecraft into a small asteroid. Whether the approach could save Earth from a future threat remains to be seen.
Crashing the 1,340-pound DART probe into the small moonlet orbiting the asteroid Didymos should redirect its trajectory – and could be a model for how to save Earth in the future.
