The New York Times has a new interactive feature detailing the things that we’ve learned so far from the New Horizons Pluto mission. It includes a bunch of short videos and I think is basically summarizing the new Science papers that appeared yesterday. The papers include studies of the atmosphere, satellites, geology, and other properties of Pluto.
NASA announced earlier today that the New Horizons spacecraft has crossed Neptune’s orbit. New Horizons is on its way toward Pluto. It will perform detailed studies of Pluto when it flies by in July next year and then hopefully continue on to study some Kuiper Belt objects.
