Tricorder Tech: The Limits, Capabilities, and Potential for Life Detection with MinION Sequencing in a Paleochannel Mars Analog
No instrument capable of direct life detection has been included on a mission payload to Mars since NASA’s Viking missions in the 1970s. This prevents us from discovering whether life […]

Accomplishments of the Curiosity Rover’s Chemistry and Mineralogy CheMin Instrument
Minerals are like a time capsule; they provide a record of what the environment was like at the time they formed. Different minerals are linked to different kinds of environments. […]
