Flagstaff may not be the center of the space exploration universe, but a constellation of science-based organizations hopes a systematic approach will draw more attention to capabilities in the region.
That conviction is one of the motivations behind a public poster session being sponsored by the Northern Arizona Planetary Science Alliance. The community, students and scientists are welcome to attend the event being held from 1–4 p.m. Wednesday, Sept. 16, at the DuBois Center Ballroom on the Northern Arizona University campus.

Nadine Barlow may be keeping her eyes on Mars, but a faint asteroid zipping along an orbit between the red planet and Jupiter has her name on it.
The asteroid, 15466 Barlow, was named in her honor by the International Astronomical Union. Now, years later, the Northern Arizona University professor of physics and astronomy finally has the official plaque.
Barlow received the plaque in March at the Lunar and Planetary Science Conference in Houston. Longtime collaborators Faith Vilas, from the Planetary… Read more

An asteroid hurtles from space and strikes the surface of Mars, creating an impact crater. The hit causes a turbulent dust cloud to flow outward, scattering a thin layer of fine-grained material that settles up to 20 times the crater’s radius. Winds normally remove this deposit within a few weeks of its formation. But in certain areas of the planet, the deposits somehow resist erosion and survive for… Read more
Lessons from underground nuclear tests and explosive volcanoes may hold the answer to how a category of unusual impact craters formed on Mars.
The craters feature a thin-layered outer deposit that extends well beyond the typical range of ejecta, said Nadine Barlow, professor of physics and astronomy at Northern Arizona University. She… Read more
