The exploration of the outer Solar System has revealed a plethora of amazing worlds, the likes of which […]

Researchers Develop New Technique to Search for Chemical Evidence of Life on Mars

Despite decades of searching, definitive evidence for life on Mars, past or present, has still remained elusive and controversial. Confirmation of such a finding would need to be thoroughly tested and documented, and now researchers at the University of Kansas have developed a new technique that they hope would help to do just that, […]

NASA Actively Working to ‘Save Opportunity and LRO’ From Budget Cutters' Axe

Opportunity at Spirit of Saint Louis crater scanning into Marathon Valley and Endeavour crater from current location on Mars in April 2015 in this photo mosaic. The crater, featuring an odd mound of rocks, is the gateway to Marathon Valley and exposures of water altered clay minerals. This pancam camera photo mosaic was assembled […]
