Investigators who studied the crash of the European Space Agency’s Schiaparelli lander on Mars last year have recommended more stringent testing and computer modeling before the launch of a joint European-Russian landing craft in 2020 to avoid a repeat of the mistakes that doomed the probe’s descent through the Martian atmosphere.
In the final months of Europe’s LISA Pathfinder mission, scientists have found an unexpected use for the trailblazing testbed for a future gravitational wave observatory by tracking the tiny dings made by microscopic particles that strike the spacecraft in deep space, exploiting the impacts to learn about the population of dust grains cast off by comets and asteroids across the solar system.
The ExoMars Trace Gas Orbiter, a Russian-launched, European-built spacecraft that arrived at Mars in October, is starting to dip into the upper reaches of the red planet’s atmosphere in a year-long “aerobraking” campaign place the observatory in the right position to hunt for methane, an indicator of potential biological activity.
Scientists observing a curious neutron star in a binary system known as the ‘Rapid Burster’ may have solved a forty-year-old mystery surrounding its puzzling X-ray bursts. They discovered that its magnetic field creates a gap around the star, largely preventing it from feeding on matter from its stellar companion.
