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.
It may not seem like it, but it is approaching two years now since New Horizons made its historic flyby of Pluto and its moons in July 2015. But even though it has been quiet since then, the mission continues, as the spacecraft is now preparing for its next flyby of another Kuiper Belt Object (KBO) on Jan. 1, 2019 – and now New Horizons has reached the halfway point between Pluto and the next target, called 2014 MU69. It’s another major milestone for a mission that gave us our first close-up views of the Pluto system, and revealed worlds utterly alien and unique in the Solar System.
Long after its incredible encounter with Pluto and its moons in 2015, the New Horizons spacecraft is continuing its journey deeper into the Kuiper Belt in the outer reaches of the Solar System. Mission scientists and engineers are now preparing for its next close flyby, of a smaller body called 2014 MU69, on Jan. 1, 2019. Along the way, New Horizons makes occasional slight course corrections to keep it on track, and now the spacecraft has just successfully completed its latest one.
The New Horizons mission to Pluto has been nothing less than incredible, giving us our first close-up views of this enigmatic dwarf planet and its moons. But the show isn’t over yet, as the New Horizons team is now planning for its next encounter with another Kuiper Belt Object (KBO) in 2019. But even before then, the spacecraft has been busy observing other smaller objects, and has now collected the first science data on one of them, called 1994 JR1.
The announcement of a possible large ninth planet in our Solar System way beyond Neptune last month caused a lot of excitement, needless to say. If confirmed, it may be similar to “super-Earth” type exoplanets which have been found to be plentiful around other stars, although none, that we knew of, around ours. At this point, however, it is still a well-presented theory. Now, there’s another possibility which has been offered to explain the weird orbits of some of the small Kuiper Belt objects – not a large planet, but rather a second Kuiper Belt consisting of many smaller objects instead.
