The two space agencies are preparing to find out if it's possible to knock a rogue asteroid off its deadly trajectory. The world's first planetary defense operation hopes to investigate the effects of a collision with a small "didymoon" space rock orbiting the Didymos A asteroid) spacecraft invading space space rock and ESA's HERA mission in the effects are examined.
The mission, however, depends on an agreement between the politicians gathered later this month in Seville to decide which projects will be funded The next few years.
Owing to the uncertainty, 1,200 scientists, including the astronomer Royal Lord Rees, wrote to the ministers warning them against the risk of being unable to finance the asteroid mission.
They wrote: "As citizens of our solar system, we must expand our knowledge of the universe in which we live and how we can protect our planet from the dangers of space.

of square kilometers or more.
"Unlike other natural disasters, an asteroid impact on Earth is not just one we can predict, but one that we can prevent by just testing it.
"Today We are the first generation of people to have the technology to try to change the trajectory of an asteroid.
"We urge governments to keep the upcoming Hera mission high on the agenda … and to provide new and vital knowledge that is needed for our protection and future generations.

Asteroid Hazard: 1
Asteroids are the remnants of emerging planets ranging in size from a few feet to several hundred kilometers.
Just like the earth, they orbit the sun and sometimes they are dangerous. No threat can be averted near the earth.
Tens of millions of asteroids are larger than 30 feet, which means they may have more energy than a small nuclear weapon when they enter the Earth's atmosphere.  Scientists have so far identified only 21,443, which is less than 20 percent of the total.
The call for funding was made at a press conference in Berlin before the ministerial meeting in Spain.
Dr. Patrick Michel, AIDA / HERA Principal Investigator said: "New asteroids are now being discovered at a rate of about four per day.
" We need a coordinated international strategy to reduce the impact of near-earth objects.
"Collaboration with AIDA will result We have a unique opportunity to test our ability to deflect an asteroid in combination with fascinating science."
The NASA DART mission is expected to launch next year and be completed in 2022 at the binary asteroid Didymos B orbits half a mile Didymos A
The system discovered in 1966 orbits the Sun every 771 days and is classified as an asteroid that is "potentially dangerous" to our planet. is.
