Next Stop for Curiosity Rover? Lava Mound May Hold Answers to Ancient Martian Lava Flows

SPACE While NASA’s Curiosity Rover revealed a possible location for reoccurring lakes on the surface of the red planet last week, NASA’s Mars Reconnaissance Orbiter is finding even larger discoveries from its vantage point in the sky. Capturing new images with its HiRISE camera, one of six onboard instruments used by the orbiter, Reconnaissance has found evidence of one of the largest lava mounds found to date. And while it looks like a crispy pie pulled right from the oven, researchers say that the 1.2-mile wide circle of Martian crust is composed of iron-rich metamorphic rock, created thousands of years ago in a series of lava flows.

Future Mars Missions Threatened by Cosmic Radiation

Young would-be space explorers received some bad news this week. Due to the Sun entering in to a phase of relatively low solar activity, cosmic radiation is projected to increase to such levels that any prolonged manned space expedition would prove harmful and even deadly to the astronauts involved.

Watch: NASA Moves Martian Orbiters to Avoid Comet Siding Spring
