TARGET: EUROPA Slamming a spent fuel tank into the surface of Jupiter’s icy moon Europa could vibrate the surface so much that a spacecraft flying by (shown in artist’s illustration) could see the tremors. Scientists might be able to analyze the tremors to gauge the thickness of the ice.
MISSION TO MARS By the 2030s, NASA and the aerospace industry want to send a crew to explore Mars, seen in this simulated image based on data from the Mars Global Surveyor orbiter.
SURF’S UP Meteor impacts may have generated supersized tsunamis on Mars that reshaped the coastlines of an ocean around 3.4 billion years ago. Red-shaded region shows the reach of the more recent of two tsunamis.
