Old enough to vote in many countries, the Mars Advanced Radar for Subsurface and Ionospheric Sounding (MARSIS) is finally receiving an update that will make the search for Martian water easier. It searches for water beneath Mars’ surface using sound waves, whose reflections researchers use to make maps of the Martian underground. With the software update, MARSIS will be able to collect and send better data to Earth without having to store it in its memory, which is a feature that slows it down. Read full article here

‘Ghostly’ neutrinos provide new path to study protons
In groundbreaking research, an international collaboration of scientists from the University of Rochester have used a beam of neutrinos to measure the size and shape of the protons that make up the nuclei of atoms. This feat, once thought impossible, provides scientists with a new way of looking at the small components of an atom’s nucleus and opens up a wealth of new information about the structure of an atom’s nucleus and the dynamics of the forces that affect neutrino interactions. The researchers solved the challenge of harnessing neutrinos in large numbers by using a neutrino detector containing a target of both hydrogen and carbon atoms, and over nine years of data collection at Fermilab’s accelerator.
