Paul Chodas, manager of NASA's Center for Near-Earth Object Studies, helped design and host the recent simulation, as well as five previous exercises like it that the agency has hosted since 2013. In total NASA has helped lead seven asteroid-impact scenarios in the last eight years.
But the outcomes have, for the most part, had a worrisome similarity: In all but one, at least part of the incoming space rock has hit Earth.
Two Asteroids That Could Be As Big As Football Fields to Zip Past Earth
The first of the pair of large space rocks to make a close approach to our planet is an object known as 2021 KC.
According to NASA 's Center for Near Earth Object Studies (CNEOS,) the asteroid is estimated to measure somewhere between around 174 feet and 394 feet in diameter.
Data from the CNEOS shows that 2021 KC will make a close approach to the Earth on May 21 at 11:36 p.m. Coordinated Universal Time (UTC), or 7:36 p.m. ET.
Spacecraft heads for Earth with asteroid sample | Technology Today | theredstonerocket.com
Bennu ejects particles from its surface Jan. 19, 2019. The image was created by combining two images taken aboard OSIRIS-REx.
After nearly five years in space, NASA's Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer – OSIRIS-REx – spacecraft is on its way back to Earth with an abundance of rocks and dust from the near-Earth asteroid Bennu.
On May 10 at 3:23 p.m., the spacecraft fired its main engines full throttle for seven minutes – its most significant maneuver since it arrived at Bennu in 2018. This burn thrust the spacecraft away from the asteroid at 600 miles per hour, setting it on a 2 ½-year cruise toward Earth.

5 of the Most Significant Impact Craters in North America - HISTORY
There are roughly 180 known impact craters worldwide and fully a third of them—including some of the biggest—are located in North America. These massive blast zones were formed by meteors, asteroids and comets that slammed into the earth’s surface with a force many times greater than today’s most powerful nuclear bombs.
A popular tourist destination, the bowl-shaped Barringer Crater or “Meteor Crater” in Arizona is one of the most recognizable impact craters in North America. It was formed 50,000 years ago when a hunk of iron called the Canyon Diablo meteorite struck the earth at an estimated speed of 26,000 mph. The rock, measuring 100 feet across, was barely slowed by the Earth’s atmosphere and struck with an explosive force greater than 20 million tons of TNT.
Biodiversity devastation: Human-driven decline requires millions of years of recovery
Lake Volvi (Greece) temporarily dries up as a consequence of excessive irrigation for agriculture paired with climate change - one of many examples of a freshwater system under human impact.
Pyrgulifera matheronii, a freshwater snail common at the time of the dinosaurs and extinct along with them. Cretaceous, Hungary.
The current biodiversity crisis, often called the 6th mass extinction, is one of the critical challenges we face in the 21st century. Numerous species are threatened with extinction, mostly as a direct or indirect consequence of human impact. Habitat destruction, climate change, overexploitation, pollution and invasive species are among the main causes for Earth's biota to decline rapidly.
Mass Effect: Should You Fight Balak Or Let Him Go? | TheGamer
Bring Down the Sky was one of the DLC packs for Mass Effect but it is automatically included in the base game as part of the Legendary Edition. This content sees Shepard becoming more acquainted with the Batarians on Asteroid X57. Like the main story missions, the location for this assignment will be flagged on the Galaxy map.
You'll have to disable three fusion torches on Asteroid X57 in order to avoid a collision with a nearby human planet called Terra. However, at the end of this assignment, you'll be faced with a moral dilemma that echoes in the following games in the series.
