STS056-90-034 (8-17 April 1993) --- Backdropped against heavy cloud cover over the Mediterranean Sea, the SPARTAN-201 satellite was captured on 70mm by crewmembers aboard the Space Shuttle Discovery. SPARTAN is a free-flying payload designed to study the solar wind and part of the sun's corona. The project was conceived in the late 1970s to take advantage of the opportunity offered by the Space Shuttle to provide more observation time for the increasingly more sophisticated experiments than the five to ten minutes provided by sounding rocket flights. On the mission's third day, Astronaut Ellen Ochoa, Mission Specialist, used the remote manipulator system (RMS) to lift the satellite from its support structure on Discovery and release it in space. The reusable craft was later recaptured and returned to Earth with the crew. Note the tip of Discovery's vertical stabilizer at frame's edge.

One of NASA newest Earth-observing instruments, the SeaWinds scatterometer aboard Japan Advanced Earth Observing Satellite Adeos 2--now renamed Midori 2--has successfully transmitted its first radar data to our home planet.

Karma Snyder, a project manager at NASA's John C. Stennis Space Center, was a senior design engineer on the RL10 liquid rocket engine that powered the Centaur, the upper stage of the rocket used in NASA's Lunar CRater Observation and Sensing Satellite (LCROSS) mission in October 2009. Part of the LCROSS mission was to search for water on the moon by striking the lunar surface with a rocket stage, creating a plume of debris that could be analyzed for water ice and vapor. Snyder's work on the RL10 took place from 1995 to 2001 when she was a senior design engineer with Pratt & Whitney Rocketdyne. Years later, she sees the project as one of her biggest accomplishments in light of the LCROSS mission. 'It's wonderful to see it come into full service,' she said. 'As one of my co-workers said, the original dream was to get that engine to the moon, and we're finally realizing that dream.'
This satellite image, taken by NASA's Earth-observing Terra satellite on Aug. 18, 2019, shows the ECOSTRESS study area in the Amazon Basin and smoke from active fires in the rainforest. ECOSTRESS also captured an image of the Amazon rainforest, PIA23432, revealing water-stressed and non-stressed forest in the area. The water-stressed areas of the forest look as green and healthy as these cooler areas, making them invisible except to a radiometer that can measure thermal infrared energy from the surface. https://photojournal.jpl.nasa.gov/catalog/PIA23546

An artist's rendition of the next Landsat satellite, the Landsat Data Continuity Mission (LDCM) that will launch in Feb. 2013. Credit: NASA The Landsat program is the longest continuous global record of Earth observations from space – ever. Since its first satellite went up in the summer of 1972, Landsat has been looking at our planet. The view of Earth that this 40-year satellite program has recorded allows scientists to see, in ways they never imagined, how the Earth's surface has transformed, over time. In the 1970s Landsat captured the first views from space of the Amazonian rainforest and continued to track the area year after year after year, giving the world an unprecedented view of systemic and rapid deforestation. This view from space let us see an activity that was taking place in an exceptionally remote part of our world. These now iconic-images of tropical deforestation spurred the global environmental community to rally in an unprecedented way, and resulted in worldwide attention and action.

VANDENBERG AIR FORCE BASE, Calif. -- A security guard waits to clear NASA's National Polar-orbiting Operational Environmental Satellite System Preparatory Project (NPP) satellite through the gates of Vandenberg Air Force Base in California. NPP represents a critical first step in building the next-generation of Earth-observing satellites. NPP will carry the first of the new sensors developed for this satellite fleet, now known as the Joint Polar Satellite System (JPSS), to be launched in 2016. NPP is the bridge between NASA's Earth Observing System (EOS) satellites and the forthcoming series of JPSS satellites. The mission will test key technologies and instruments for the JPSS missions. NPP is targeted to launch Oct. 25 from Space Launch Complex-2 aboard a United Launch Alliance Delta II rocket. For more information, visit http://www.nasa.gov/NPP.

VANDENBERG AIR FORCE BASE, Calif. -- At Space Launch Complex-2 at Vandenberg Air Force Base in California, technicians check the position as a crane moves a solid rocket motor closer to the United Launch Alliance Delta II rocket. The Delta II will carry NASA’s National Polar-orbiting Operational Environmental Satellite System Preparatory Project (NPP) satellite into space.
