ISS006-E-33084 (24 February 2003) --- Astronauts Kenneth D. Bowersox (right) and Donald R. Pettit, Expedition Six mission commander and NASA ISS science officer, respectively, participate in a scheduled extravehicular activity (EVA) development test objective (DTO) in the Quest Airlock on the International Space Station (ISS). The test demonstrated the ability of two crewmembers to safely get into the American Extravehicular Mobility Unit (EMU) spacesuit without the assistance of a third crewmember; that ability is a prerequisite to sending smaller crews to ISS while the space shuttle fleet remains grounded during the investigation of the Columbia accident. Bowersox and Pettit helped each other into their EMU spacesuits, donned jet backpacks called Simplified Aid for EVA Rescue (SAFER), set up the necessary equipment for a pre-breathe of oxygen to purge nitrogen from their bloodstreams, and then got out of the spacesuits.

This artist's concept depicts the stationary NASA Mars lander known by the acronym InSight at work studying the interior of Mars. The InSight mission (for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) is scheduled to launch in March 2016 and land on Mars six months later. It will investigate processes that formed and shaped Mars and will help scientists better understand the evolution of our inner solar system's rocky planets, including Earth. InSight will deploy two instruments to the ground using a robotic arm: a seismometer (contributed by the French space agency Centre National d'Etudes Spatiales, or CNES) to measure the microscopic ground motions from distant marsquakes, providing detailed information about the interior structure of Mars; and a heat-flow probe (contributed by the German Aerospace Center, or DLR) designed to hammer itself 3 to 5 meters (about 16 feet) deep and monitor heat coming from the planet's interior. The mission will also track the lander's radio to measure wobbles in the planet's rotation that relate to the size of its core and will include a camera and a suite of environmental sensors to monitor the weather and variations in the magnetic field. Lockheed Martin Space Systems, Denver, is building the spacecraft. Note: After thorough examination, NASA managers have decided to suspend the planned March 2016 launch of the Interior Exploration using Seismic Investigations Geodesy and Heat Transport (InSight) mission. The decision follows unsuccessful attempts to repair a leak in a section of the prime instrument in the science payload. http://photojournal.jpl.nasa.gov/catalog/PIA17358

KENNEDY SPACE CENTER, FLA. -- Endeavour is towed in front of the Vehicle Assembly Building (VAB) where it is going for temporary storage. The orbiter has been moved from the Orbiter Processing Facility (OPF) to allow work to be performed in the OPF that can only be accomplished while the bay is empty. Work scheduled in the OPF includes annual validation of the bay’s cranes, work platforms, lifting mechanisms and jack stands. Endeavour will remain in the VAB for approximately 12 days, then return to the OPF.
