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.

An Arizona-led spacecraft mission is headed toward a carbon-rich asteroid called Bennu, and today it’s close enough to take the first photograph of its destination. KNAU’s Melissa Sevigny reports.

Mars Rover Curiosity has dug up organic material in rocks just below the surface of what’s believed to be an ancient Martian lake bed.

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

Some scientists who study Mars also study Northern Arizona. That’s because our lava fields and water-carved canyons are similar to Martian terrain. It’s a good place to test out whether future colonists on Mars would be able to build houses out of local materials. That’s what astronomer Antonio Paris of St. Petersburg College in Florida is doing. He’s traveling the Colorado Plateau collecting soil samples to see if they’ll make good cement. He told KNAU’s Melissa Sevigny, if works here, it might also work on Mars.
