Fly over Pluto and Charon for second anniversary of New Horizons’ historic visit

Pluto is a world of wonders, with vast glaciers and plains of nitrogen ice, mountains of water ice capped with methane snow, ancient rivers and lakes of liquid nitrogen, massive “ice spikes” reaching 500 metres tall (similar to Penitentes on Earth but much larger), a possible subsurface ocean and a hazy blue atmosphere.

It was two years ago today that NASA’s New Horizons spacecraft became the first-ever probe to visit Pluto in the cold, outer fringes of the Solar System. To help celebrate the occasion, NASA has posted a new video of the epic flyby, when the spacecraft soared over the tall mountains and vast icy plains of this small but active world.

New Horizons team successfully observes transit of next KBO target, and clouds on Pluto!

With the Pluto flyby now well behind them, the New Horizons team has been busy preparing for the next encounter, the small Kuiper Belt Object (KBO) called 2014 MU69. New Horizons is scheduled to fly past 2014 MU69 on Jan. 1, 2019, and it will be the farthest Solar System body to ever be visited so far. From June 2-3, astronomers in Argentina and South Africa pointed their telescopes at 2014 MU69, hoping to catch its “shadow” moving across a background star as it transited the star (also known as a stellar occultation). This would help determine the object’s exact size and allow the mission team to fine-tune the planned flyby. Back at Pluto, there is more evidence, from data gathered by New Horizons during the flyby, for clouds in Pluto’s thin atmosphere.
