Planetary Defense at NASA

In 2016, NASA established the Planetary Defense Coordination Office (PDCO) to manage the agency's ongoing mission of finding, tracking, and better understanding asteroids and comets that could pose an impact hazard to Earth. Here you can stay informed about the PDCO, NASA's Near-Earth Object (NEO) Observations Program, and upcoming planetary defense flight missions, including NASA'S NEO Surveyor mission.

Planetary Defenders

NASA’s Planetary Defenders is a gripping documentary that delves into the high-stakes world of asteroid detection and planetary defense by journeying alongside NASA’s dedicated team of scientists, astronomers, and engineers who discover, track, and monitor near-Earth asteroids to safeguard Earth from potential impacts. Available now on NASA+ and other streaming platforms.

How would humanity respond if we discovered an asteroid headed for Earth? NASA’s "Planetary Defenders" is a gripping documentary that delves into the high-stakes world of asteroid detection and planetary defense.

NASA Planetary Defense:
Backyard Asteroid Observer

Backyard astronomer Robert Holmes of Westfield, Illinois, is part of NASA's army of observers scanning the night sky for asteroids.

"We do follow-up observations with NASA's near-Earth observations program. All night long, I'm running big telescopes. One's a 24-inch, a 30-inch, and a 32-inch. And then the 50 inch is my… my biggest telescope [...]."

"[...] We do follow-up observations for the discoveries that are made by the large sky surveys. By looking at these asteroids, and measuring these asteroids, we can determine what their possibilities of actually hitting the Earth in the future are going to be.

NASA provides coordinates of specific objects that they need observations on. I'm gonna punch in the coordinates here, and I'm doing this remotely from inside a control room, not at the telescope. And so, we look these objects up and then use those coordinates to look at a tiny piece of the sky that this object happens to be in. And then we follow those objects, and define and refine orbits for those objects, and reduce the uncertainty of where it's going to go in the near future.

I started off as a volunteer in 2006. It's just blossomed into a full-time opportunity to work for NASA under their grant program, where I'm now doing this every single clear night.

Now we're starting the observing run for 2017 KK3. You don't build a telescope that's this big without having… being passionate about what you do. I'm really driven to be a part of a program that's important and has importance to the future. And we're not talking about next year or the year after, We're talking about asteroids that could potentially hit the Earth 100 years from now. And the work we do today may make a difference 100 years from now."

Backyard astronomer Robert Holmes of Westfield, Illinois, is part of NASA's army of observers scanning the night sky for asteroids. By observing and tracking asteroids, NASA programs can determine whether an asteroid is potentially hazardous to Earth -- now or years in the future. In 2015, Bob made 36,000 asteroid observations -- the most by anyone in a single year. He started off as a volunteer in 2006, and his hobby has since blossomed into a full-time opportunity to work for NASA under a grant program.

Orbits of Potentially Hazardous Asteroids

Explanation:
Are asteroids dangerous? Some are, but the likelihood of a dangerous asteroid striking the Earth during any given year is low. Because some past mass extinction events have been linked to asteroid impacts, however, humanity has made it a priority to find and catalog those asteroids that may one day affect life on Earth. Pictured here are the orbits of the over 1,000 known Potentially Hazardous Asteroids (PHAs). These documented tumbling boulders of rock and ice are over 140 meters across and will pass within 7.5 million kilometers of Earth -- about 20 times the distance to the Moon. Although none of them will strike the Earth in the next 100 years -- not all PHAs have been discovered, and past 100 years, many orbits become hard to predict. Were an asteroid of this size to impact the Earth, it could raise dangerous tsunamis, for example. To investigate Earth-saving strategies, NASA successfully tested the Double Asteroid Redirection Test (DART) mission in 2022. Of course, rocks and ice bits of much smaller size strike the Earth every day, usually pose no danger, and sometimes create memorable fireball and meteor displays.
