A meteoroid recently slammed into the side of a hillside on Mars, exploding on impact, destabilising the slope and triggering a long avalanche. The crater only measures about five meters (16 feet) across, but the avalanche left a dark trail of dry dust stretching a full kilometre (0.62 miles) down the side of a slope in a hilly region of the red planet. The image was captured by the High Resolution Imaging Science Experiment – HiRISE – aboard NASA’s Mars Reconnaissance Orbiter spacecraft.
NASA confirms evidence that liquid water flows on today’s Mars
New findings from NASA’s Mars Reconnaissance Orbiter (MRO) provide the strongest evidence yet that liquid water flows intermittently on present-day Mars. Using an imaging spectrometer on MRO, researchers detected signatures of hydrated minerals on slopes where mysterious darkish streaks that appear to ebb and flow over time are seen on the Red Planet.
Jupiter’s moon Ganymede shows hints of Solar System’s largest impact
Blue aurorae in Mars’ sky visible to the naked eye
For the first time, an international team of scientists from NASA, the Institute of Planetology and Astrophysics of Grenoble (IPAG), the European Space Agency and Aalto University in Finland, have predicted that colourful, glowing aurorae can be seen by the naked eye on a terrestrial planet other than Earth — Mars.
