NASA and others are making elaborate plans to protect Earth from asteroids.

What would we do if we knew an asteroid was on 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.

No immediate threat

Though there’s no immediate threat, the International Academy of Astronautics’ 2019 Planetary Defense Conference next week at The Hotel at the University of Maryland will include an “asteroid impact exercise” featuring a realistic, but fictional scenario where an asteroid is on an impact trajectory with Earth. The scenario has been developed by the NASA Jet Propulsion Laboratory’s Center for NEO Studies (CNEOS).

NASA Administrator Jim Bridenstine will deliver the conference’s keynote address, while Bill Nye, chief executive officer of The Planetary Society, will participate in a panel discussion about defending Earth from asteroids. That will stream live on Wednesday, May 1, 2019 here.

Impact craters like Manicouagan in Quebec, Canada, are rare, but NASA, other U.S. agencies and international partners are gathering to simulate impact scenarios and discuss the best course of action for disaster mitigation.

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 June2018 Astronomers estimate there are about 1,000 near-Earth asteroids larger than a kilometer across. If one of those struck Earth, no amount of preparation would help, but there are many small asteroids that science could potentially do something about before they strike.

What is the scenario?

Astronomers “discover” a NEO called 2019 PDC that’s potentially hazardous to Earth, track it for a few months, and decide it has a 1 in 100 chance of impact with Earth in2027 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 have really helped us in the planetary defense community to understand what our colleagues on the disaster management side need to know,” said Lindley Johnson, NASA’s Planetary Defense Officer.

It’s actually the sixth NEO impact exercise that NASA has taken part in, and what it’s learned so far is that few agencies on the ground are interested in the technical details of the asteroid. “What emergency managers want to know is when, 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 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 do would 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 it sounds. Smash into an asteroid, or rather, one of its moons, then study it to see if it’s altered course.

How to deflect an 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 fire one of its Falcon 9 rockets in the direction of asteroid 65803 Didymos (or “Didymain”) and its tiny satellite “Didymoon.” A binary asteroid, it will pass close to Earth in October 2022 (though it poses no threat), and it’s hoped that by 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 by 0.4 mm/s, which will in turn slightly alter the 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 is not going to be a quick result since the ESA’s Hera mission won’t launch until October 2023, and won’t reach Didymos until2026 After that, hopefully, we’ll know how asteroids react to being smashed into, and whether they alter course.

Then we might be ready to cope if get advance warning of “the big one”.
