As ESA mission manager Ian Carnelli explains, "We will gain insight into ... how the technique could be applied if a real threat were to occur." "To protect Earth from potentially hazardous impacts, we need to understand asteroids much better—what they are made of, their structure, origins, and how they respond to collisions," an ESA lead investigator says of the plan, revealed Wednesday at the European Planetary Science Congress in France.
As such, before AIM retreats to a safe distance to watch the impact, it will first study Didymoon`s mass, density, and internal structure. The mission is set to launch in October 2020 and will meet up with the binary system in May 2022.
Per the ESA, Didymos will be "comparatively close" to Earth in 2022, at a distance of about 6.8 million miles; the Independent reports it came within 4.5 million miles of our planet in 2003.
(In the meantime, here`s how humanity might survive an asteroid strike.)
