What would we do if we knew and asteroid a collision course with Earth? That’s the question that will be asked next week as NASA, the European Space Agency and others prepare for the possibility of a near-Earth object (NEO) impact in future.

What is a near-Earth object?

A NEO is defined as anything, asteroid or comet, that orbit the Sun and come within 30 million miles (50 million kilometers) of Earth’s orbit. The exercise is part of the National Near-Earth Object Preparedness Strategy and Action Plan that the White House published in June 2018. Astronomers estimate there are about 1,000 near-Earth asteroids larger than a kilometer across. If one of these struck Earth, the amount of preparation would help, but there are many small asteroids that could potentially do something about before they strike.

What is the scenario?

Astronomers “discover” a NEO called 2019 PDCs potentially hazardous to Earth, track it for a few months, and decide it has a 1 in 100 chance of impact with Earth in 2027. Among NEO watchers, 1 in 100 is the magic number and means it’s time to take the threat super-serious. After all, the future of humanity could be at stake.

‘Simulated emergency’

The simulated emergency Exercise will include NASA’s Planetary Defense Coordination Office (PDCO), the European Space Agency’s Space Situational Awareness NEO Segment and the International Asteroid Warning Network (IAWN). “These exercises really helped us in the planetary defense community to understand what our colleagues need to know on the disaster management side,” said Lindley Johnson, NASA’s Planetary Defense Officer.

It’s actually the sixth NEO impact exercise that NASA has taken part in, and what is learned so far is that & nbsp; few agencies on the ground are & nbsp; interested in the technical details of the asteroid. “What emergency managers know when is where, where and how an asteroid would impact, and the type and extent of damage that could occur,” said Leviticus Lewis of the Response Operations Division for the Federal Emergency Management Agency (FEMA).

ESA’s Hera mission concept, currently under study, would be humanity’s first mission to a binary asteroid: the 780 m diameter Didymos is accompanied by a 160 m diameter secondary body.

How to & nbsp; cope with an Earth-bound NEO?

When it comes to potential NEO strikes there’s a lot of international collaboration on “asteroid mitigation.” It’s called the Asteroid Impact and Deflection Assessment ( AIDA, and it will be more fun than the sounds. Smash into an asteroid, rather, one of its moons, then study it to see if it’s altered course.

How to deflect and asteroid

Set for launch June 2021, the NASA’s Double Asteroid Redirection Test (DART) mission will be the first spacecraft impact asteroid redirect mission. It was announced earlier this month that NASA had awarded [$ $ 69 million to SpaceX to four one of its Falcon 9 rockets in the direction of asteroid 65803 Didymos (or “Didymain”) and its tiny satellite ” Didymoon ” & nbsp; A binary asteroid, it will pass close to Earth in October 2022 (though it poses no threat), and it’s hoped that then the DART spacecraft will be ready to slam into Didymoon, and slightly change its course using a technique called “kinetic deflection.” The 500 kg DART will crash into the asteroid moon at about 6 km / s and, hopefully, change its orbital velocity at 0.4 mm / s, which will turn slightly altered trajectory of Didymos.

Is “asteroid redirect” plausible?

Will DART work? The European Space Agency’s “Hera” follow-up mission, effectively an asteroid rendezvous spacecraft, will tell us if an impactor works. It will survey both the Didymos asteroid and its moon, using an asteroid framing camera, also using lasers, a star-tracker, a thermal infrared camera, and accelerometers to see if DART’s “asteroid redirect” worked or not. It will get within 200 meters of the moon and study the impact crater left by DART

Using its laser altimeter Hera scans Didymoon’s surface. ESA’s Hera mission concept, currently under study, would be humanity’s first mission to a binary asteroid: the 780 m diameter Didymos is accompanied by a 160 m diameter secondary body.

However, this The ESA’s mission won’t launch until October 2023, and won’t reach Didymos until 2026. After that, hopefully, we’ll know how asteroids react to being smashed into, and whether they

Then we might be ready to cope with the advance warning or “the big one.”
