            "title": "Swift and Hubble Probe an Asteroid Crash",
            "description": "Late last year, astronomers noticed that an asteroid named Scheila had unexpectedly brightened and it was sporting short-lived plumes. Data from NASA's Swift satellite and Hubble Space Telescope show that these changes likely occurred after Scheila was struck by a much smaller asteroid. On Dec. 11, 2010, images from the University of Arizona's Catalina Sky Survey, a project of NASA's Near Earth Object Observations Program, revealed the Scheila to be twice as bright as expected and immersed in a faint comet-like glow. Looking through the survey's archived images, astronomers inferred the outburst began between Nov. 11 and Dec. 3. Three days after the outburst was announced, Swift's Ultraviolet/Optical Telescope (UVOT) captured multiple images and a spectrum of the asteroid. Ultraviolet sunlight breaks up the gas molecules surrounding comets; water, for example, is transformed into hydroxyl (OH) and hydrogen (H). But none of the emissions most commonly identified in comets — such as hydroxyl or cyanogen (CN) — show up in the UVOT spectrum. The absence of gas around Scheila led the Swift team to reject scenarios where exposed ice accounted for the activity.Images show the asteroid was flanked in the north by a bright dust plume and in the south by a fainter one. The dual plumes formed as small dust particles excavated by the impact were pushed away from the asteroid by sunlight. Hubble observed the asteroid's fading dust cloud on Dec. 27, 2010, and Jan. 4, 2011.The two teams found the observations were best explained by a collision with a small asteroid impacting Scheila's surface at an angle of less than 30 degrees, leaving a crater 1,000 feet across. Laboratory experiments show a more direct strike probably wouldn't have produced two distinct dust plumes. The researchers estimated the crash ejected more than 660,000 tons of dust—equivalent to nearly twice the mass of the Empire State Building.For the collision animation go to #10759. || ",

            "title": "SLIC: The Unsung Hero of Servicing Mission 4",
            "description": "The composite Super Lightweight Interchangeable Carrier (SLIC) is a new breed of equipment carrier that will allow the Space Shuttle to transport a full complement of scientific instruments and other components to Hubble. Made of carbon fiber with a cyanate ester resin and a titanium metal matrix composite, SLIC is the first all-composite carrier to fly on the shuttle. This flat, reusable pallet looks very different from the carriers flown on previous Hubble servicing missions because of its efficient design. This design, plus SLIC's composite construction, makes it much lighter and stronger than traditional aluminum carriers. About half the weight of its predecessors, SLIC shows a dramatic increase in performance over other Hubble equipment carriers, with nearly double the carrying capability. || ",

The incredible engineering challenge to understand the problem, develop a strategy to fix ACS that astronauts could perform, create the tools and new circuit board components in an incredibly short time, could not have been accomplished if the Space Telescope Imaging Spectrograph (STIS) hadn't failed a few years ealier. Goddard Engineers leveraged techniques they developed for STIS repair to fix ACS. || ",

            "description": "Space Telescope Imaging Spectrograph (STIS), the most versatile spectrograph ever to fly on Hubble, ceased operations in August 2004 due to the failure of its power supply. In order to restore STIS to operational status, astronauts will perform a never-before-attempted on-orbit replacement of an electronics board inside STIS's main electronics box. On Earth this operation is relatively simple, but in space many challenges confront the astronauts as they work to replace the failed board including working to remove 111 tiny, non-captive screws with astronaut gloves.  The Cosmic Origins Spectrograph  (COS) that will be added during Servicing Mission 4, and STIS are highly complementary and are very complimentary to each other providing scientists with a full set of spectroscopic tools for astrophysical research. The STIS instrument's accomplishments include determining the atmospheric composition of an exoplanet as well as spectra and images at ultraviolet and visible wavelengths of the Universe from our solar system out to cosmological distances.
