Summary:
    Massive landslides, similar to those found on Earth, are occurring on the asteroid Ceres. That's according to a new study adding to the growing evidence that Ceres retains a significant amount of water ice.

is it even possible? I don't think Ceres has any gravity, seems like a "landslide" would cause  the debris to be flung into space

All objects with mass have gravity. Ceres is massive enough to have gravity compress it into a sphere.

yes, but with such low gravity it wouldn't take much for a "landslide" to reach escape velocity

Future colony of New Texas?

Just considering that not only should Texas be its own country (again), maybe even its own planet.

you asked for it...

Ceres's surface gravity is about 3% of Earth's. Take Newtonian physics and calculate the end velocity of a landslide on both Earth and Ceres, you will see that the end velocity on Ceres is much lower than on Earth for the same height. The only energy source for a landslide in both places is the potential energy of height and on neither body can the rubble even get close to escape speed. Also take into consideration the vector of acceleration is downward, not upwards.

Think on it a little bit before you post nonsense.

There was a Japanese probe Hyabusa that sent a tiny robot that was supposed to bounce along the surface of a small asteroid, the release point was too high and the bouncy robot just went into space.

The operative word here is "small". Hyabusa was sent to a small irregular asteroid. Ceres is classified as a dwarf planet. it is on the asteroid belt, but it is definitely not an asteroid.

I shall call him "Joe" and never have to hear him again, since sound doesn't travel in space and the ignore function is high-powered
