Well, hello, Pluto. Nice to finally meet you!
3 billion miles. That's quite a trek.
A star trek, if you will.
It's more than a million road trips from New York City to Los Angeles. Or, for those of you who'd get carsick, roughly 32 trips to the sun.
It's also about the distance between Earth and Pluto — a historic journey completed by NASA's New Horizons probe on July 14, 2015.
NASA launched the piano-sized spacecraft into space back in 2006 with the goal of capturing images very close to Pluto's surface.
As of July 14, 2015, we officially have our first up-close photos of the ex-planet.
And Pluto was more than ready for its close up.
Here's what New Horizons caught on camera:
Gorgeous Pluto! The dwarf planet has sent a love note back to Earth via our New Horizons spacecraft, which has traveled more than 9 years and 3+ billion miles. This is the last and most detailed image of Pluto sent to Earth before the moment of closest approach, which was at 7:49 a.m. EDT Tuesday - about 7,750 miles above the surface -- roughly the same distance from New York to Mumbai, India - making it the first-ever space mission to explore a world so far from Earth. This stunning image of the dwarf planet was captured from New Horizons at about 4 p.m. EDT on July 13, about 16 hours before the moment of closest approach. The spacecraft was 476,000 miles (766,000 kilometers) from the surface. Images from closest approach are expected to be released on Wednesday, July 15.

This photo — which took several hours to get from the New Horizons spacecraft to Earth — was taken at about 4 p.m. Eastern on July 13 and debuted on Instagram the morning of July 14. It marks the first of its kind taken of Pluto.
Pluto may look close (and it is, relatively speaking), but this image was snapped about 476,000 miles from the dwarf planet's surface!
"I'm thrilled," Katie Bechtold, a flight controller on the team, told Upworthy. "It's almost unbelievable that after all these years of hard work, our little piano-size robot is finally getting to show us Pluto."
That incredible image is part of a bigger mission to learn a lot more about the icy dwarf planet billions of miles away.
Sure, we know some things about Pluto. Take, for instance, gravity: It isn't as much of a thing there. If you weigh 100 pounds on Earth, you'd weigh 7 on Pluto! Or, consider its massive orbit around the sun: 248 Earth years = 1 Pluto year. And as far as its size? We're talking smaller than our own moon.
But New Horizons wants to dig deeper! Bechtold explained to Upworthy that New Horizons will hopefully give us Earthlings a more in-depth look into things like Pluto's composition, geology, atmosphere, and surface temperature. The probe will also check out Charon, the largest of Pluto's five known moons.
That's great, you might be thinking, but isn't that info sort of ... useless knowledge? No way!
A better glimpse at Pluto helps us understand our own home here on planet Earth.
For one, there's Pluto's unique atmosphere. It's escaping into space! And nothing like that is happening anywhere else in our solar system. But scientists think it used to happen here on Earth, too, when our atmosphere was hydrogen-helium (a long, long time ago). By studying Pluto, the team at New Horizons is hoping to better understand the evolution of our own atmosphere.
New Horizons may teach us more about comets, too. Pluto is in the Kuiper Belt — the outermost region of our solar system. This frigid "third zone" is where tons of cometary impactors come from, including — quite possibly — the one that wiped out the dinosaurs! Documenting the sizes of craters on Pluto and its moons may provide helpful context about comets and how they affect the planets around us.
The New Horizons mission hasn't just been a success for space exploration — it's been a big win for gender equality, too.
Bechtold, a self-proclaimed "intersectional geek feminist activist," said she's proud to be on a team where women have played critical roles in the group's success. Half of New Horizons' mission operations team is women. That may seem like no big deal, but considering the hurdles women face in science, tech, and math-related fields, it's an impressive feat.
The mission is one of the most female-driven space explorations in history, according to New Horizons.
The mission is far from over, though. The team already has post-Pluto plans in mind.
The probe may be far away, but there's plenty to discover out there on the Kuiper Belt, such as thousands of comets and dwarf planets. A few of these objects — known as Kuiper Belt Objects, or KBOs — are possible flyby targets for the spacecraft in the coming years. The New Horizons team and NASA are working to nail down which one the probe can check out while it's near our solar system's peripheral. All the candidates are about a billion miles past Pluto!
Pending a few things, like NASA's approval and funding for the extended trip, the next phase in New Horizons' journey could begin in 2017.
So space nerds, rejoice! We may not have seen the last from what New Horizons has to offer.
