Both space agencies are preparing to discover whether it is possible to push a deceptive asteroid out of its lethal trajectory. The world's first planetary defense operation hopes to study the effect of a collision with a small Didymon cosmic rock orbiting the asteroid Didimos A.
The Joint Asteroid Impact Assessment and Aviation Mission (AIDA) consists of a double test for a self-test NASA Asteroids (DAR) spacecraft to hit the space rock, and the ESA HERA mission to conduct impact studies.
However, the mission depends on the agreement of the politicians who meet in Seville later this month to decide which projects will be funded in the coming years.

They wrote: "As citizens of our Solar System, we need to expand our knowledge of the universe we live in and how we can protect our planet from the dangers that occur in space.

"Asteroids near Earth will either hit the Earth's surface or burst into flames, or burst into flames, or burst into flames. in both cases, they cause serious damage to thousands of regions per square kilometer or more.
"Unlike other natural disasters, asteroid impact with Earth is not only what we know how to predict, but also what we can prevent through means that just need to be tested.
"Today, we are the first generation of people who have the technology they need to try to change the trajectory of an asteroid.
"We strongly urge governments to keep the forthcoming Hera mission on the agenda … by providing new and vital knowledge necessary to protect themselves and future generations. "

Asteroids are remnants of nascent planets ranging in size from a few feet to hundreds of miles.
Just like Earth, they orbit the Sun and sometimes come dangerously close to Earth and nothing can be done to
Tens of millions of asteroids are greater than 30 feet, which means that they potentially have energy greater than a small nuclear weapon if they enter the earth's atmosphere. financing is on
Dr. Patrick Michel, AIDA / Hera Principal Investigator, said: "New asteroids are now being discovered at a speed of about four per day.
" We need a coordinated international
AIDA collaboration will give us the unique opportunity to test our ability to deflect an asteroid combined with fascinating science. ”
The NASA DART mission is likely to launch next year, arriving in the binary asteroid system in 2022, where it will immediately collapse into the wide 525 feet of Didymos B, about half a mile away from Didymos A
discovered in 1966. system that orbits the sun every 771 days and is classified as an asteroid "potentially dangerous" to our planet.
