May 16, 2009 (provided by NASAexplorer): 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 STISs 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.

March 31, 2009 (By H. Josef Hebert): After more than a decade of work and $3.5 billion, engineers have completed the world's most powerful laser, capable of simulating the energy force of a hydrogen bomb and the sun itself. The federal Energy Department announced Tuesday that it has officially certified the National Ignition Facility at the Lawrence Livermore National Laboratory in California, clearing the way for a series of experiments over the next year that eventually is hoped will mimic the heat and pressure found at the center of the sun. The facility, the size of a football field, comprises 192 separate laser beams, each traveling 1,000 feet in one-thousandth of a second to converge simultaneously on a target the size of a pencil eraser.
