The Mars Space Flight Facility at ASU runs a program that allows students to use the camera on NASA’s Mars Odyssey orbiter. Through the program, a seventh grade science class in Cottonwood, CA, found what appears to be a previously undiscovered lava tube skylight:
From the PhysOrg writeup:
“This pit is certainly new to us,” Glen Cushing told the students. “And it is only the second one known to be associated with Pavonis Mons.” He estimated it to be approximately 190 by 160 meters (620 x 520 feet) wide and 115 meters (380 feet) deep at least.
When I was in junior high science class, we spent time dissecting cow eyeballs, not harnessing the power of a NASA Mars orbiter.
