Scaled to fly SpaceShipOne for the period of one year.

Louros Valles.

These latest images show a system of sapping channels, called Louros Valles (named in 1982 after river in Greece), south of the Ius Chasma canyon which runs east to west.

These images were taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express during orbit 97 from an altitude of 269 kilometres. The images have a resolution of about 13 metres per pixel and are centred at 278.8º East and 8.3º South. The colour image has been created from the nadir and three colour channels. North is at the right.

Earth's Magnetic Field Reversal Takes 7,000 Years.

Scientists have known for a long time now that the Earth's magnetic field unexpectedly reverses polarity over long periods of time, but how often this happens was still a mystery. Brad Clement, a geologist funded by the National Science Foundation, has concluded that the reversal seems to happen every 7,000 years, on average. He gathered this data by analyzing deep-ocean sediment cores. One surprise is that the variation seems to alter with latitude - the directional change takes half as long at low-latitude sites as it does at mid- to high-latitude sites.

Cassini Sees Merging Storms on Saturn.

NASA's Cassini spacecraft continues its approach to Saturn, and its latest images show incredible detail of two storms in the act of merging. The storms were both at least 1,000 km wide, and they were moving westward across the surface of the planet, relative to its rotation. After about a month of dancing, the storms actually merged on March 19-20, and the new storm now sits almost stationary on the surface of the planet. Saturn is the windiest planet in the Solar System, and the reason for these winds is one of the mysteries that scientists hope to solve with Cassini.

Galaxy NGC 300 by Hubble Space Telescope.

The Hubble Space Telescope has been focused to peer deep into the heart of nearby Galaxy NGC 300, and revealed the stars as individual points of light; even though it's 6.5 million light-years away. Hubble's Advanced Camera for Surveys has resolved the Galaxy 10 times better than ground-based telescopes, which can only see the brightest individual stars.

SpaceShipOne Gets Government Approval.

The US Department of Transportation announced this week that it has given Scaled Composites a license to fly its SpaceShipOne suborbital spacecraft. The license was issued on April 1, and allows Scaled to fly SpaceShipOne for the period of one year. This authorization is required for all the X-Prize contenders who plan to launch their vehicles within the United States. On April 8, SpaceShipOne completed its second supersonic test flight - this time it traveled up to Mach 2, beating its own record.
