Venus Express atmospheric drag measurements

06 October 2010

This animation demonstrates the orbital perturbations due to atmospheric drag experienced by Venus Express just around the pericentre pass of its orbit, at an altitude below 200 km. The orbital perturbation results in a shrinking of the elliptical orbit of Venus Express: the apocentre altitude, or the point along the orbit which is the farthest from the planet, is lowered, and the orbit becomes slightly less elliptical and more circular (the effect has been exaggerated in the animation).
