New Horizons is going to reach Pluto in July, 2015. What happens after that?
New Horizons will arrive at Pluto in mid-2015. Images of ancient tectonic features on its surface may provide evidence for the existence of an ancient, subsurface ocean.
Pluto’s small satellites have very low escape velocities, which means that dust kicked up by impacts has a relatively easy time of escaping rather than settling back down to the little moon’s surface. Today’s paper looks at the fates of that dust.
The number of known moons of Pluto has now reached five. What are they like, and how did they get there? Kenyon and Bromley use numerical simulations to answer these questions and determine what else New Horizons may find in 2015.
