  Preparing for the Shuttle Mission The NASA Railroad transported the last space shuttle solid rocket booster segments over the Indian River on the 13-mile trip from the Jay Jay Rail Yard in Titusville, Fla., to NASA's Kennedy Space Center. Six cars transported the segments along the Florida East Coast Railway, which began at the ATK solid rocket booster plant in Promontory, Utah. The booster segments will be used for shuttle Atlantis on what currently is planned as the "launch on need," or potential rescue mission for the final shuttle flight, Endeavour's STS-134 mission.

  X-51A Makes Longest Scramjet Flight The X-51A successfully made the longest supersonic combustion ramjet-powered hypersonic flight to date off the southern California coast on May 26. It was powered by a SJX61-2 that was first validated in a NASA wind tunnel. The air-breathing scramjet engine, built by Pratt & Whitney Rocketdyne, burned for more than 200 seconds to accelerate the U.S. Air Force's X-51A vehicle to Mach 5, or five times the speed of sound. It broke the previous record for the longest scramjet burn in a flight test, set by NASA's X-43 vehicle. In this image from 2008, the SJX61-2 successfully completed ground tests simulating Mach 5 flight conditions at NASA's Langley Research Center, Hampton, Va. Image Credit: NASA

  Spacewalker Anchored to a Canadarm2 mobile foot restraint Garrett Reisman conducts the mission's first spacewalk. During the seven-hour, 25-minute spacewalk, Reisman and Steve Bowen installed a second antenna for high-speed Ku-band transmissions and added a spare parts platform to Dextre, a two-armed extension for the station’s robotic arm.

  Atlantis Lifts Off Space shuttle Atlantis lifted off from Launch Pad 39A at NASA's Kennedy Space Center in Florida on the STS-132 mission to the International Space Station at 2:20 p.m. EDT on May 14. The third of five shuttle missions planned for 2010, this was the last planned launch for Atlantis. The Russian-built Mini Research Module-1, also known as Rassvet, or "dawn," will be delivered and it will provide additional storage space and a new docking port for Russian Soyuz and Progress spacecraft. The laboratory will be attached to the bottom port of the station's Zarya module. The mission's three spacewalks will focus on storing spare components outside the station, including six batteries, a communications antenna and parts for the Canadian Dextre robotic arm.

  STS-125 Crew Visits the Stock Exchange NASA astronauts Scott Altman and Mike Massimino of the STS-125 mission visit the New York Stock Exchange to support the release of Hubble 3D, the newest IMAX film, which documents the mission to repair the Hubble Space Telescope and features never-before-seen 3D flights through Hubble imagery such as the Orion Nebula. In honor of the occasion, Altman and Massimino ring 'The Closing Bell' ending the day's trading at the Exchange on Thursday, March 18, 2010. Image Credit: NYSE (Used by permission)

  Experience Hubble's Universe in 3-D This image depicts a vast canyon of dust and gas in the Orion Nebula from a 3-D computer model based on observations by NASA's Hubble Space Telescope and created by science visualization specialists at the Space Telescope Science Institute (STScI) in Baltimore, Md. A 3-D visualization of this model takes viewers on an amazing four-minute voyage through the 15-light-year-wide canyon. The model takes viewers through an exhilarating ride through the Orion Nebula, a vast star-making factory 1,500 light-years away. This virtual space journey isn't the latest video game but one of several groundbreaking astronomy visualizations created by specialists at STScI, the science operations center for NASA's Hubble Space Telescope. The cinematic space odysseys are part of the new Imax film Hubble 3D, which opens today at select IMAX theaters worldwide. The 43-minute movie chronicles the 20-year life of Hubble and includes highlights from the May 2009 servicing mission to the Earth-orbiting observatory, with footage taken by the astronauts. The giant-screen film showcases some of Hubble's breathtaking iconic pictures, such as the Eagle Nebula's "Pillars of Creation," as well as stunning views taken by the newly installed Wide Field Camera 3. While Hubble pictures of celestial objects are awe-inspiring, they are flat 2-D photographs. For this film, those 2-D images have been converted into 3-D environments, giving the audience the impression they are space travelers taking a tour of Hubble's most popular targets. Based on a Hubble image of Orion released in 2006, the visualization was a collaborative effort between science visualization specialists at STScI, including Greg Bacon, who sculpted the Orion Nebula digital model, with input from STScI astronomer Massimo Roberto; the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign; and the Spitzer Science Center at the California Institute of Technology in Pasadena. For some of the sequences, STScI imaging specialists developed new techniques for transforming the 2-D Hubble images into 3-D. STScI image processing specialists Lisa Frattare and Zolt Levay, for example, created methods of splitting a giant gaseous pillar in the Carina Nebula into multiple layers to produce a 3-D effect, giving the structure depth.

  Mars Express Images Phobos This image of Mars' moon Phobos was taken by the High Resolution Stereo Camera (HRSC) on Mars Express. The HRSC camera is operated by the German Aerospace Center and the Mars Express mission is operated by the European Space Agency. The HRSC took this image using the nadir channel on March 7, 2010, on HRSC Orbit 7915. The image has been enhanced to bring out the features in the less illuminated areas. Visit the German Aerospace Center page for 3-D and other imagery of Phobos. Image Credit: ESA/DLR/FU Berlin (G. Neukum)

  Bursting at the Seams Dramatic plumes, both large and small, spray water ice out from many locations along the famed 'tiger stripes' near the south pole of Saturn's moon Enceladus. The tiger stripes are fissures that spray icy particles, water vapor and organic compounds. This mosaic was created from two high-resolution images that were captured by the narrow-angle camera when NASA's Cassini spacecraft flew past Enceladus and through the jets on Nov. 21, 2009. Imaging the jets over time will allow Cassini scientists to study the consistency of their activity. Image Credit: NASA/JPL/Space Science Institute
