Venus' draggin' and twistin' atmosphere

here's a new story I wrote in the last couple of days for ESA about some cool experiments to study the atmosphere of our sister planet Venus:

Venus Express probes the planet's atmosphere by flying through it

ESA's Venus Express is exploring the density of the Venusian upper atmosphere by measuring how much the planet's atmosphere itself slows down or twists the pointing of the spacecraft. New density measurements, centred on the Northern Pole and obtained during these atmospheric drag experiments, show an unexpected inhomogeneous pattern in the atmosphere of our neighbouring planet.
