Study: NASA Space Strike Might Have Reshaped an Asteroid
A new study suggests that an asteroid strike by an American spacecraft likely changed the shape of the targeted object.

Study: NASA Space Strike Might Have Reshaped an Asteroid
NASA crashed the DART spacecraft into the asteroid Dimorphos in 2022.

Study: NASA Space Strike Might Have Reshaped an Asteroid
The asteroid strike happened about 11 million kilometers from Earth.

Study: NASA Space Strike Might Have Reshaped an Asteroid
The experiment tested a method for changing the orbit of some asteroids to prevent them from possibly crashing into our planet in the future.

Study: NASA Space Strike Might Have Reshaped an Asteroid
NASA has said its studies of the crash showed it was successful because the force of the strike changed the asteroid’s orbit around a larger

asteroid Didymos. NASA’s measurements also found the strike reduced the orbital period of Dimorphos by 33 minutes.

Study: NASA Space Strike Might Have Reshaped an Asteroid
Such a major crash would normally create a large crater in the targeted object.

But a new study presents evidence that the crash made more than a hole it likely changed the shape of the whole asteroid.

Study: NASA Space Strike Might Have Reshaped an Asteroid
The researchers said their simulation method has been used in the past to recreate space objects crashing into each other.
