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.

“The stars aligned for this observing campaign, which was implemented expertly by the team,” said New Horizons Program Executive Adriana Ocampo at NASA Headquarters in Washington, D.C. “It’s amazing how classical astronomy – from small telescopes to some of the most advanced observatories on Earth – is helping New Horizons plan its next flyby, and it shows how truly global space exploration is.”

The observations went well it seems, according to Principal Investigator Alan Stern, with data collected from all 54 observing teams involved (known as KBO Chasers).
