            "description": "Shortly after NASA Administrator Michael Griffin announced that NASA would add a servicing mission to the Hubble Space Telescope, Hubble's most prominent camera and most used instrument, died. 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": "Advanced Camera for Surveys (ACS) produced many of the most popular and dramatic images from the Hubble Space Telescope over the last few years, but in January 2007 the instrument had a serious power failure which caused the three observing channels, the Wide Field Channel, The Solar Blind Channel and the High Resolution channel, to cease operation. The Solar Blind Channel was returned to service in February 2007. This animation shows how the Servicing Mission 4 astronauts will attempt to repair the Advanced Camera for Surveys by replacing the CCD electronics box in the Wide Field Channel and power this box with a replacement low voltage power supply. If this repair is successful, ACS will again provide the most sensitive images available at visible and near-infrared wavelengths. || ",

            "title": "HST SM4 STIS Repair EVA",
            "description": "Space Telescope Imaging Spectrograph (STIS), the most versatile spectrograph ever to fly on Hubble, ceased operations in August 2004 due to failure of its power supply. In order to restore STIS to operational status, astronauts may attempt an on-orbit replacement of one electronics board inside one of its main electronics boxes. The Cosmic Origins Spectrograph (COS) that will be added during Servicing Mission 4, and STIS are highly complementary and would work effectively together to provide 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. || ",

            "description": "Hubble's Advanced Camera for Surveys (ACS) was responsible for many of Hubble's most impressive images of deep space. In January 2007, ACS experienced an electrical short that put two of its three cameras out of commission. ACS contains a trio of cameras: the wide field camera, the high-resolution camera, and the solar blind camera. Each performed a specific function.This animation depicts the procedure planned to repair ACS. Astronauts will remove 4 circuit boards from inside the instrument, install a redesigned pack containing new circuit boards and then re-route the power going to the instrument. || ",
