When scientists first observed the asteroid Bennu up close in 2018, they were shocked to find that its surface was covered with sizeable boulders.

From Earth, Bennu appeared smooth.

But it turns out the asteroid is able to maintain huge clumps of rock in the harsh environment of space — igniting new questions about asteroid evolution and erosion.
