NASA’s New Horizons spacecraft, which visited Pluto three years ago, flew by another frozen world in the outer regions of the solar system last night. Ultima Thule is now the most distant object ever visited by a spacecraft. Will Grundy of Flagstaff’s Lowell Observatory is one of the scientists involved. He spoke with KNAU’s Melissa Sevigny from mission control in Maryland.

Fifty years ago today, astronauts orbiting the Moon captured a photograph that some people say changed the world. It was the first color photograph of Earth from space. Bill Anders, Jim Lovell, and Frank Borman took the unplanned picture from Apollo 8 just as the blue Earth began to rise over the pale lunar surface. KNAU’s Melissa Sevigny spoke with local space historian Bill Sheehan about why the “Earthrise” photo mattered in 1968, and still matters today.

A NASA spacecraft operated by the University of Arizona has discovered water locked up in clay minerals on an asteroid. KNAU’s Melissa Sevigny reports, some scientists believe asteroids may have delivered water and organic molecules to Earth in its early history, sparking the origin of life.

A NASA mission to an asteroid arrives at its destination today. OSIRIS REx is led by the University of Arizona and it’s the first U.S. spacecraft to visit an asteroid with plans to bring a sample of it back home. Scientists say the mission will tell us about the origins of the solar system and how to protect Earth from asteroid impacts. KNAU’s Melissa Sevigny spoke with deputy principal investigator Heather Enos.
