Stellary Starry Universe

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

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.

Floating just below the International Space Station, astronaut Nicholas Patrick put some finishing touches on the newly installed cupola space windows last week. Patrick was a mission specialist onboard the space shuttle Endeavor’s recently completed STS-130 mission to the ISS. Image Credit: NASA

 

Radio astronomers have uncovered 17 millisecond pulsars in our galaxy by studying unknown high-energy sources detected by NASA’s Fermi Gamma-ray Space Telescope.

At NASA’s Kennedy Space Center in Florida, work platforms are moved into position around space shuttle Endeavour in Orbiter Processing Facility-2, following its touchdown at the completion of the STS-130 mission to the International Space Station on Feb. 21.

Processing now begins for Endeavour’s next flight, STS-134. The six-member STS-134 crew will deliver the Express Logistics Carrier 3 and the Alpha Magnetic Spectrometer to the International Space Station, as well as a variety of spare parts including two S-band communications antennas, a high-pressure gas tank, additional spare parts for Dextre and micrometeoroid debris shields. STS-134 will be the 35th shuttle mission to the station and the 133rd flight in the shuttle program. Launch is targeted for July 29. Image Credit: NASA/Kim Shiflett
