An Ingenious Perseverance: The Search for Life on Mars

Abstract: Recently, NASA’s Perseverance rover (equipped with the Ingenuity helicopter) landed on Mars and is investigating the crater Jezero, a place where scientists think they might fight find possible signs of life through the leftover marks of deltas and rivers and the rocks that might contain life-signalling minerals. The Perseverance rover is only a part …

Design for a Europa Subsurface Explorer Mission with a Telescopic Subsurface Vehicle

Abstract Europa, one of Jupiter’s four large Galilean moons, is a target of prime importance for exploration. This is due to the likely presence of a global subsurface liquid water ocean beneath a water ice crust, raising the possibility that Europa could support simple life. Future mission concepts include a lander deploying a probe to …
