NASA's freshly painted Stratospheric Observatory for Infrared Astronomy (SOFIA) 747SP aircraft sits outside a hangar at L-3 Communications Integrated Systems' facility in Waco, Texas. The observatory, which features a German-built 100-inch (2.5 meter) diameter infrared telescope weighing 20 tons, is approaching the flight test phase as part of a joint program by NASA and DLR Deutsches Zentrum fuer Luft- und Raumfahrt (German Aerospace Center). SOFIA's science and mission operations are being planned jointly by Universities Space Research Association (USRA) and the Deutsches SOFIA Institut (DSI). Once operational, SOFIA will be the world's primary infrared observatory during a mission lasting up to 20 years, as well as an outstanding laboratory for developing and testing instrumentation and detector technology.

This map of Ceres, constructed from data collected by NASA's Dawn spacecraft, shows the dwarf planet's surface with features that have been named as of August 14, 2015. This is a simple cylindrical projection centered on 0 degrees east longitude, created by science team members at the German Aerospace Center (DLR). The most recently named feature is the small crater Kait, after the Hattic goddess of grain. It is a mere 0.2 miles (0.4 kilometers) across. A full list of crater names on Ceres is available at http://planetarynames.wr.usgs.gov/SearchResults%3Ftarget=CERES. http://photojournal.jpl.nasa.gov/catalog/PIA19625

KENNEDY SPACE CENTER, Fla. -- Framed by branches of oak leaves in this photo, Space Shuttle Endeavour, on its mobile launcher platform, is transferred to Launch Pad 39A for mission STS-99. The van behind it is barely noticeable next to the gigantic stature of the moving vehicle. Named the Shuttle Radar Topography Mission (SRTM), it involves an international project spearheaded by the National Imagery and Mapping Agency and NASA, with participation of the German Aerospace Center DLR. The SRTM consists of a specially modified radar system that will gather data for the most accurate and complete topographic map of the Earth's surface that has ever been assembled

Inside the Multi-Payload Processing Facility, the lid covering the Shuttle Radar Topography Mission (SRTM) is lifted from the crate. The primary payload on mission STS-99, the SRTM consists of a specially modified radar system that will fly onboard the Space Shuttle during the 11-day mission scheduled for September 1999. This radar system will gather data that will result in the most accurate and complete topographic map of the Earth's surface that has ever been assembled. SRTM is an international project spearheaded by the National Imagery and Mapping Agency and NASA, with participation of the German Aerospace Center DLR. Its objective is to obtain the most complete high-resolution digital topographic database of the Earth
