A spokeswoman for the Phoenix Mars Lander mission says a hacker managed to change the lead story on the mission's public Web site overnight. Spokeswoman Sara Hammond says the University of Arizona-hosted site has been taken down while computer experts work to resolve the problem. Hammond says the latest mission update posted Friday afternoon was replaced with a hacker's signature and a link redirecting to the hacker's overseas Web site.

As seen in the top centre of this image from Phoenix, the exhaust from the descent engine has blown soil off to reveal either rock or ice, which has not yet been determined.
Scientists have discovered what may be ice that was exposed when soil was blown away as NASA's Phoenix spacecraft landed on Mars last Sunday, May 25. The possible ice appears in an image the robotic arm camera took underneath the lander, near a footpad.
Scientists for the Phoenix Mars Lander are wrestling with a short circuit on the spacecraft. Scientists said Friday that the problem is in a device designed to analyse ice and soil dug from the planet's surface. The short circuit was found during testing of the robot.
Nasa's Mars lander Phoenix has unstowed its robotic arm - the key tool in its mission to test the red planet's soil for the building blocks of life. The 2.35m-long titanium and aluminium extension will dig below the Martian topsoil to the water-ice which is thought to lie just beneath.
NASA's Mars lander is returning more detailed images from the Martian surface and is now preparing its instruments for science operations. Phoenix transmitted a 360-degree panorama of its frigid Martian world, freed its nearly 8-foot robotic arm, tested a laser instrument for studying dust and clouds, and transmitted its second weather report on Wednesday evening.

The 10-km-wide crater seen in the background is named Heimdall. The Phoenix lander eventually landed 20 km in front of the crater.
With data recorded on board Mars Express, you can hear Phoenix descend on to the surface of the Red Planet. After being processed by the Mars Express Flight Control Team, the sounds of Phoenix descending are audible, loud and clear. Listen now
The data from the Mars Express Lander Communication system (MELACOM) that tracked Phoenix was received on Earth soon after the Phoenix landing.
Colour View to Northwest of NASA Mars Phoenix Lander This approximate colour (SSI's red, green, and blue filters: 600, 530, and 480 nanometers) view was obtained on sol 2 by the Surface Stereo Imager (SSI) on board the Phoenix lander. The view is toward the northwest, showing polygonal terrain near the lander and out to the horizon.
