Nasa S Osiris Rex Have Discovered That The Heat From The Sun Cracked The Rocks On Asteroid Bennu
Scientists from NASA’s OSIRIS-REX have discovered that the heat from the Sun cracked the rocks on Bennu in just 10,000 to 100,000 years, showing that surface regeneration occurs much more quickly on asteroids than on Earth. The researchers examined rock cracks on the asteroid Bennu using high-resolution photos taken by the spacecraft OSIRIS-REX to arrive at its conclusions (Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer). With the aid of this knowledge, scientists will be able to predict the time it takes boulders on asteroids like Bennu to fragment into smaller pieces, some of which may eject into space while others may remain on the asteroid’s surface....
