This image was taken on February 13, 2010 and received on Earth February 15, 2010. The camera was pointing toward Mimas at approximately 69,730 kilometers away, and the image was taken using the CL1 and GRN filters. This image has not been validated or calibrated. A validated/calibrated image will be archived with the NASA Planetary Data System in 2011. Full-Res: N00151588.jpg Image Credit: NASA/JPL/Space Science Institute

ESA: Today Mars Express began a series of flybys of Phobos, the largest moon of Mars. The campaign will reach its crescendo on 3 March, when the spacecraft will set a new record for the closest pass to Phobos, skimming the surface at just 50 km. The data collected could help untangle the origin of this mysterious moon.

The European Space Agency is about to launch the most sophisticated satellite ever to investigate the Earth's ice fields and map ice thickness over water and land: lift-off scheduled for 25 February.

ESA's ice mission satellite CryoSat will be placed into orbit 700 km above Earth by a Russian Dnepr rocket to be launched from the Baikonur Cosmodrome in Kazakhstan.

These six narrow-angle color images were made from the first ever 'portrait' of the solar system taken by Voyager 1, which was more than 4 billion miles from Earth and about 32 degrees above the ecliptic. Image credit: NASA/JPL Full image and caption

Twenty years ago on February 14, NASA's Voyager 1 spacecraft had sailed beyond the outermost planet in our solar system and turned its camera inward to snap a series of final images that would be its parting valentine to the string of planets it called home.

The Cassini spacecraft spies two types of waves in Saturn's A ring: a spiral density wave on the left of the image and a more pronounced spiral bending wave near the middle.

See Two Kinds of Wave to learn more about these two kinds of waves. The slight pixelation visible near the brightest and darkest lines is an unavoidable result of the size of the camera's sensor and of image processing.

The first batch of concrete was poured Thursday, February 11, marking the start of the final concrete finish phase of the runway construction at Spaceport America, the world's first purposebuilt commercial spaceport.
