Blasting Off Into History
NASA’s Space Shuttle Program conducted the final test firing of a reusable solid rocket motor Feb. 25 in Promontory, Utah. The flight support motor, or FSM-17, burned for approximately 123 seconds–the same time each reusable solid rocket motor burns during an actual space shuttle launch. Preliminary indications show all test objectives were met. After final test data are analyzed, results for each objective will be published in a NASA report. The test–the 52nd conducted for NASA by ATK Launch Systems, a unit of Alliant Techsystems Inc.–marks the closure of a test program that has spanned more than three decades. The first test was in July 1977. The ATK-built motors have successfully launched the space shuttle into orbit 129 times. Image Credit: NASA
The Possibility of a Brand New World
Several of the dwarf galaxies of in the Hickson Compact Group 31 are slowly merging. Will the result of these galactic collisions be one big elliptical galaxy? Most assuredly. The pictured galaxies of Hickson Compact Group 31 will pass through and destroy each other, millions of stars will form and explode, and thousands of nebula will form and dissipate before the dust settles and the final galaxy emerges about one billion years from now. The above image is a composite of images taken in infrared light by the Spitzer Space Telescope, ultraviolet light by the GALEX space telescope, and visible light by the Hubble Space Telescope. Hickson Compact Group 31 spans about 150,000 light years and lies about 150 million light years away toward the constellation of Eridanus. Image Credit: NASA, ESA, J. English (U.

ESA highlights the potential of satellite data for the European Investment Bank
The European Investment Bank has an annual lending portfolio of around 75 billion euros, operating globally in more than 130 countries. The Bank has been increasingly mainstreaming environmental considerations into its lending portfolio, boosting the need to monitor the impact of the projects it funds. As its environmental commitments have increased, so too has the demand for geospatial information.
