Credits: NASA/Goddard/Rebecca Roth --- More info: Hubble’s payload computer, which controls and coordinates the observatory’s onboard science instruments, halted suddenly on June 13. When the main computer failed to receive a signal from the payload computer, it automatically placed Hubble’s science instruments into safe mode. That meant the telescope would no longer be doing science while mission specialists analyzed the situation. In response to the anomaly, NASA began a switch to backup spacecraft hardware on Hubble in response to an ongoing problem with its payload computer. This was a multi-day event. Science observations restarted the afternoon of Saturday, July 17.

The latest image of Pacific Ocean sea surface heights from the NASA OSTIM/Jason-2 oceanography satellite, on June 11, 2010, shows that Pacific has switched from warm red to cold blue during the last few months.

Expedition 60 flight engineers Christina Koch and Nick Hague of NASA work together on the Main Bus Switching Unit aboard the space station to replace a failed circuit card before performing a test to ensure its functionality.

KENNEDY SPACE CENTER, Fla. -- In the Orbiter Processing Facility bay 3, workers are ready to move a main bus switching unit into Discovery's payload bay. A main bus switching unit is used for power distribution, circuit protection and fault isolation on the space station's power system. The units route power to proper locations in the space station, such as from solar arrays through umbilicals into the U.S. Lab. The unit will be installed on the external stowage platform 2 attached to the Quest airlock for temporary storage. Discovery is targeted to launch mission STS-120 no earlier than Oct. 20.

KENNEDY SPACE CENTER, FLA. - During power-up of the orbiter Discovery in the Orbiter Processing Facility, a technician turns on a switch. Discovery has been undergoing Orbiter Major Modifications in the past year, ranging from wiring, control panels and black boxes to gaseous and fluid systems tubing and components. These systems were deserviced, disassembled, inspected, modified, reassembled, checked out and reserviced, as were most other systems onboard. The work includes the installation of the Multifunction Electronic Display Subsystem (MEDS) - a state-of-the-art “glass cockpit.”
