How to Prevent our Spacecraft From Contaminating Mars

Mars has become something of an international playground over the past twenty years. There are currently eleven missions from five space agencies exploring the Red Planet, a combination of orbiters, landers, and rovers. Several additional robotic missions will be leaving for Mars in the next few years, and crewed missions are planned for the 2030s. Because of this increase in ...

Perseverance Sees Evidence of Flash Floods in Jezero Crater

Nearly eight months into the Perseverance rover’s mission on Mars, researchers have confirmed that Jezero crater is (as was believed) an ancient lakebed, but more significantly, that it once experienced powerful flash floods that pushed boulders from tens of miles upstream into the crater basin. Years before Perseverance ever left Earth, orbital photographs of Jezero crater showed what looked to ...

Although it’s Quiet Today, Mars Once had Thousands of Volcanic Eruptions on its Surface

Earth is a geologically active planet, which means it has plate tectonics and volcanic eruptions that have not ceased. This activity extends all the way to the core, where action between a liquid outer core and a solid inner core generates a planetary magnetic field. In comparison, Mars is an almost perfect example of a “stagnant lid” planet, where geological ...
