Titan-7 is the eighth targeted encounter of Saturn's largest moon. The flyby occurs on Wednesday 7 September at 08:12 UTC. The closest approach will be at an altitude of 1075 km above the surface at a speed of 5.9 km s-1. Titan has a diameter of 5150 km, so the spacecraft passes just a Titan radii. The phase on approach is approximately 50°, reaching 85° at closest approach, and is approximately 128° outbound. The lower phase angles are good for the Cassini cameras.

On 9 August 1975 ESA's first scientific satellite, Cos-B, was launched. Cos-B was ESA's first foray into producing a spacecraft with a single payload: a high-energy gamma-ray telescope. The mission was a remarkable success and returned the first detailed observations of gamma-ray emission from within our galaxy.

Thanks to measurements by ESA's Cluster mission, a team of European scientists have identified 'micro' -vortices in Earth's magnetosphere. Such small-scale vortex turbulence, whose existence was predicted through mathematical models, has not been observed before in space. The results are not only relevant for space physics, but also for other applications like research on nuclear fusion.

Titan possesses a dense atmosphere with a surface pressure of 1.5 bar and with N2 as its main constituent. Methane is the second most important component, but it is photodissociated on a timescale of 107 years. Because methane is still observed in Titan's atmosphere a replenishment process must be taking place through either surface, or subsurface, hydrocarbons.
