A person who's living in space for a year took these astounding photos

Astronaut Scott Kelly is halfway to making history.

Along with Russian cosmonaut Mikhail Kornienko, Kelly is about six months into a year-long mission on board the International Space Station (ISS). If the men succeed, they will be the first humans to ever spend a full year in zero gravity.

As a visual diary of his year in space, Kelly has posted a photo almost every day since arriving at the ISS in March 2015 — and the images have been incredible.

Scroll down to see someĀ of his best work.

Every morning, astronaut Scott Kelly wakes up to a view that few people get to see.

He'll enjoy it for a while. Kelly (right) and Russian cosmonaut Mikhail Kornienko (left) are about six months into a year-long mission aboard the space station.

Kelly posts a photo almost every day to document the journey, part of an online visual diary he calls #YearInSpace.

From 250 miles up, the ISS offers breathtaking views of Earth and space.

He even snapped a photo of the pyramids when he flew over Egypt.

The space station is also the best place to spot auroras. Kelly has mastered documenting these colourful atmospheric light shows.

He even put together a time-lapse video of the phenomenon. (Click to play.)

A full 'day' only lasts about 90 minutes as the station speeds around the Earth. So Kelly created another time-lapse video to crunch a full orbit in a few seconds. (Click to play.)

Space is also a great vantage to see powerful weather events, like flashes of lightning.

But Kelly isn't spending a year in space for pleasure.

Scientists are studying him and Kornienko to see how the human body changes during long-term space travel.

That data is critical if we ever hope to colonize Mars -- and the worlds beyond it.
