0 comments
It is perhaps an unlikely combination – an international team of scientists stationed in Svalbard, Norway and two polar explorers crossing the North Pole on foot. Both teams, however, are currently part of a common effort to collect vital data on the ground and from the air in support of ESA's ice mission CryoSat-2.

The onboard camera OSIRIS imaged the asteroid passing through its field of view during the spacecraft's gradual approach to Mars. The planet will be reached on 25 February 2007 for the mission's next gravity assist.

Huygenss second landing anniversary – the surprises continue

0 comments
Two years ago, planetary scientists across the world watched as Europe and the US did something amazing. The Huygens descent module drifted down through the hazy atmosphere of Saturn's moon Titan, beaming its data back to Earth via the Cassini mothership. Today, Huygens's data are still continuing to surprise researchers.

Surprises from the Edge of the Solar System

0 comments
Almost every day, the great antennas of NASA's Deep Space Network turn to a blank patch of sky in the constellation Ophiuchus. Pointing at nothing, or so it seems, they invariably pick up a signal, faint but full of intelligence. The source is beyond Neptune, beyond Pluto, on the verge of the stars themselves.
