E23 – Between a Varnished Rock and a Hard Place

Scientists have been testing whether life exists on Mars for over 40 years, ever since the Viking 1 lander touched down on the Red Planet. Researchers often perform experiments on Earth to better understand the context of data collected by Viking 1 and subsequent landers – data that gives scientists tantalizing clues about the habitability of the Martian surface.

E21 – X-rays of the Earth’s Gooey Center

Much like x-rays can show broken bones (or noses), seismic equipment can show us what’s going on in Earth’s interior. While seismologists can’t take quick snapshots like medical doctors can, they can provide an image of tectonic plate movements over time to help the scientific community – and local communities – understand geophysical phenomena from mountain formations to volcanoes to the earthquakes that rock their world.
