Joe Knows: NASA's Pluto flyby was 9 years in the making
After a journey of more than nine years and traveling 3 billion miles, the New Horizons spacecraft made it’s closet approach to Pluto Tuesday arriving just before 8 a.m. - making it the first-ever space mission to explore a world so far from Earth.
This amazing high definition image was taken approximately 7,800 miles above the frigid icy surface.
Scientists at NASA celebrated their achievement and will use these images to determine the geological landscapes, and strong atmospheric cycles which exist on the dwarf planet.
This Pluto flyby is a key moment in the history of human space exploration.
It now marks the moment that all nine planets in our Solar system have now been visited once by a NASA space probe.
On a side note, notice the large heart-shaped ice feature on the southern pole that’s captured the imagination of people around the world.
Consider it Pluto’s Antarctica - and a big hello to planet Earth!
