Planetary science: Huygens rediscovers Titan

Owen, Tobias

The first analyses of data sent by the Huygens probe from Saturn's largest moon Titan are flooding in. They paint a picture of a `Peter Pan' world - potentially like Earth, but with its development frozen at an early stage.

Planetary science: Are there active glaciers on Mars?

Montgomery, David R.; Gillespie, Alan R.; Mushkin, Amit

Magnetospheric physics: Turbulence on a small scale

Goldstein, Melvyn L.

The four-spacecraft Cluster mission has identified small-scale vortices in Earth's magnetosphere. The observation reveals processes that transfer energy and momentum from the solar wind to the magnetosphere.

Planetary science: Are there active glaciers on Mars? (Reply)

Jaumann, R.; Head, J. W.; Neukum, G. +11 more

Gillespie et al. concur with our interpretation that certain lobate equatorial and mid-latitude features on Mars are due to debris-covered glaciers formed largely during past periods of increased spin-axis obliquity, when climate regimes favoured snow and ice accumulation and glacial flow. They suggest that the `hourglass' deposit, dated at more t…

Planetary science: The impact of Deep Impact

Feldman, Paul D.

A good look at the Deep Impact cometary encounter was taken by the Rosetta mission, itself on the way to a rendezvous with a comet in 2014. So what is a comet - icy dustball or dusty iceball?

Titan team claims just deserts as probe hits moon of crème brûlée
