Forty-nine years ago tomorrow, Apollo astronauts landed on the Moon. But first they came to Flagstaff to train. Friday night the city is launching a yearlong celebration of Flagstaff’s role in the lunar missions. KNAU’s Melissa Sevigny spoke with local geologist and historian Rich Kozak about that legacy.

Astronomers at Lowell Observatory have one of the first instruments capable of detecting Earth-sized exoplanets outside our solar system.

Scientists have discovered enormous white dunes made of methane ice on Pluto. They were found in high-resolution images taken by NASA’s New Horizons spacecraft. KNAU’s Melissa Sevigny reports it’s a mystery how they formed.

In the last few years, Pluto has gone from being a fuzzy dot in the sky to a geologically active world of mountains, canyons, and heart-shaped glaciers. That’s thanks to NASA’s New Horizons spacecraft, which sailed by Pluto in 2015 to photograph it up close for the first time. The mission’s leader Alan Stern is currently on a book tour and visits Flagstaff today. He spoke with KNAU’s Melissa Sevigny from the road.

About 30 miles northeast of Flagstaff in a remote area of high desert, is a set of manmade craters blasted into an ancient lava flow. They were put there 50 years ago as a training site for astronauts preparing to walk and drive on the moon.
