Very proud of my PhD student Dikshita Meggi who just published her first paper in @jgrplanets! She studied how the Martian magnetic field controls the topside dynamics of the ionosphere using data from the MARSIS radar on Mars Express

The Role of the Magnetic Field Orientation on the Variability of the Martian Topside Ionosphere Using MARSIS‐Mars Express Data
The variability of topside ionospheric electron densities from MARSIS onboard Mars Express is analyzed Dayside topside layers of enhanced electron density tend to occur over horizontal magnetic f...

Dwarf planet #Ceres may have its origin in the #asteroidbelt, #MPSGoettingen scientists argue in a new @jgrplanets paper. Yellowish bright material in #ConsusCrater is rich in ammonium and connected to Ceres’ curious #cryovolcanism, they find. More here: https://t.co/lxIl0B4fWV

A really cool study led by Dave Rubin I’ve had a lot of fun participating in. We showed that Mars’ atmosphere had thinned (at least temporarily) before the last episode of subaqueous deposition in Gale crater!
