Walter Cunningham was one of three astronauts aboard the 1968 Apollo 7 mission, which paved the way for the moon landing.

NASA’s Artemis program intends to return humans to the moon after a half-century hiatus. But first, astronauts and engineers have to train and test lifesaving equipment here on Earth. So they’re returning to the same places where Apollo astronauts used to practice fifty years ago—the moonlike lava fields of Northern Arizona. KNAU’s Melissa Sevigny reports.

James A. McDivitt, who commanded the Apollo 9 mission testing the first complete set of equipment to go to the moon, has died. He was 93.

NASA announced yesterday that a spacecraft which slammed into an asteroid in September successfully shifted its orbit. KNAU’s Melissa Sevigny reports, Flagstaff astronomers are among those involved in the first-ever planetary defense test.

A NASA climate research scientist who has spent much of her career explaining how global food production systems must adapt to a changing climate was awarded the World Food Prize at a ceremony at the U.S. Department of State in Washington.

The Tunnel Fire burned through Sunset Crater Volcano National Monument and headed north toward the edge of Wupatki National Monument, through a woodland of pinyon-juniper trees. That region experienced a dramatic die-off of junipers in the last few years. Before the fire, National Park Service staff partnered with NASA to map the dead trees using satellite images. KNAU’s Melissa Sevigny spoke with ecologist Nicole Ramberg-Pihl, a member of the NASA team, about their findings.

When Apollo 16 astronauts landed on the moon fifty years ago today, one of their first stops was a crater they named Flag. That’s a secret tribute to Flagstaff, Arizona, where the astronauts did their geology training. KNAU’s Melissa Sevigny spoke with local space historian Rich Kozak about Flagstaff’s unique connection to Apollo 16. Kozak has amassed a collection of archival tape about the revolutionary moon mission.

NASA plans to launch tonight that's meant to collide with a small moon orbiting an asteroid and try to change its orbit. The DART mission or Double Asteroid Redirection Test is a practice run in case an asteroid ever sets a collision course with Earth.

It’s Wednesday, June 9. Multiple people in Flagstaff reported witnessing an illuminated, flying object in the sky Tuesday evening. The National Weather…

An Arizona-led spacecraft mission begins its journey back to Earth today after successfully scooping up a sample of an asteroid. KNAU’s Melissa Sevigny…
