NASA's Landsat Satellite Looks for a Cloud-Free View

For decades, Landsat satellites have documented the desiccation of the Aral Sea in Central Asia. Once one of the largest seas in the world, it shrunk to a tenth of its original volume after Russia diverted its feeder rivers in the 1960s. Scientists studying the Aral Sea's changing ecology and retreating shoreline have looked to Landsat -- and a new feature of the Landsat Data Continuity Mission will help ensure they get a clear, cloud-free view.

NASA's GROVER Debuts On Greenland’s Ice Sheet (Our GROVER has a Grover!) -- NASA's new Earth-bound rover began testing on the Greenland ice sheet this week.
GROVER, which stands for both Greenland Rover and Goddard Remotely Operated Vehicle for Exploration and Research, is an autonomous, solar-operated robot that carries a ground-penetrating radar to examine the layers of Greenland’s ice sheet. Its findings will help scientists understand how the massive ice sheet gains and loses ice.
The GROVER team, led by glaciologist Lora Koenig from NASA's Goddard Space Flight Center in Greenbelt, Md., arrived in Summit Camp, the highest spot in Greenland, on May 6, 2013. After loading and testing the rover’s radar and fixing a minor communications glitch, the team began the robot’s tests on the ice on May 8, defying winds of up to 23 mph (37 kph) and temperatures as low as minus 22 F (minus 30 C). The GROVER tests will continue through June 8. GROVER, a prototype, was first developed in 2010 and 2011 during summer engineering boot camps at Goddard, before further refinement, with NASA funding, at Boise State University. Its trial in Greenland will also serve as a test of using rovers in harsh polar regions to gather data. #nasa #nasagoddard #grover

When did the first stars and galaxies form in the universe? How brightly did they burn their nuclear fuel?

Scientists will seek to gain answers to these questions with the launch of the Cosmic Infrared Background ExpeRIment (pictured) on a Black Brant XII sounding rocket June 4 from the Wallops Flight Facility in Virginia.

Lightning Flashes and Gravity Waves in Tropical Cyclone Mahasen - Tropical Cyclone Mahasen is moving north through the Indian Ocean along a track that places landfall along the Bangladesh coast on May 16th around 1200Z. On May 13, 2013 the Suomi NPP satellite caught an interesting glimpse of the storm as it moved off the eastern coast of India. The VIIRS Day-Night Band was able to resolve lightning flashes towards the center of the storm, along with mesopheric gravity waves emanating outwards like ripples in a pond. These gravity waves are of particular interest to air traffic controllers so assist in identifying areas of turbulence. Since the moon was in a new phase, the lights and other surface features of India and Sri Lanka are clearly visible, though the clouds of TC Mahasen are not - a tradeoff that occurs as the amount of moonlight cycles throughout the month.

Repairing the Station in Orbit --- Expedition 35 Flight Engineers Chris Cassidy (pictured) and Tom Marshburn (out of frame) completed a spacewalk at 2:14 p.m. EDT May 11, 2013 to inspect and replace a pump controller box on the International Space Station’s far port truss (P6) leaking ammonia coolant. The two NASA astronauts began the 5-hour, 30-minute spacewalk at 8:44 a.m.
A leak of ammonia coolant from the area near or at the location of a Pump and Flow Control Subassembly was detected on Thursday, May 9, prompting engineers and flight controllers to begin plans to support the spacewalk. The device contains the mechanical systems that drive the cooling functions for the port truss.

Solar Eclipse's Shadow on Earth - NASA's Terra satellite didn't observe the May 2013 eclipse directly, but it did see the moon's shadow darkening the region northeast of Australia including the Solomon Islands.

On May 10, 2013, the sun experienced what’s called an annular eclipse -- when the moon moves directly in front of the sun, but doesn’t obscure it completely. This leaves a thin, fiery ring, the annulus, visible around the outside. This eclipse was only visible from the South Pacific, along an approximately 100-mile-wide track that traverses Australia, Papua New Guinea, the Solomon Islands and the Gilbert Islands. Other areas in Australia and Indonesia saw a partial eclipse, in which the moon blocks a much smaller region of the sun.

NASA EVEX Experiment Launches from the Marshall Islands - Red and white vapor clouds filled the skies over the Marshall Islands as part of NASA’s Equatorial Vortex Experiment (EVEX). The red cloud was formed by the release of lithium vapor and the white tracer clouds were formed by the release of trimethyl aluminum (TMA). These clouds allowed scientists on the ground from various locations in the Marshall Islands to observe the neutral winds in the ionosphere.

A view of the fire in Southern California from our friend @sherisalata. She captured this image from an airplane on Friday, May 3rd. Some details from @usatoday - "A #wildfire tearing through a coastal region in Southern California nearly tripled in size as high temperatures fueled the flames, but a fire official said early Saturday that a favorable shift in the weather will likely help crews make progress against the flames.

The fire 50 miles northwest of Los Angeles mushroomed to 43 square miles Friday as 900 firefighters used engines, aircraft, bulldozers and other equipment to battle the flames."

Gigantic Rolling Wave Captured on the Sun - A coronal mass ejection (CME) erupted from just around the edge of the sun on May 1, 2013, in a gigantic rolling wave. CMEs can shoot over a billion tons of particles into space at over a million miles per hour. This CME occurred on the sun’s limb and is not headed toward Earth. The prominence you see erupting here is 25 Earth radii across at the point where it hits the outside of the frame. This image was captured in extreme ultraviolet light by NASA’s Solar Dynamics Observatory (SDO). #nasa #nasagoddard #sun #cme #sdo #mayday

Enter the Vortex - in Psychedelic Color.

This spectacular, vertigo inducing, false-color image from NASA's Cassini mission highlights the storms at Saturn's north pole. The angry eye of a hurricane-like storm appears dark red while the fast-moving hexagonal jet stream framing it is a yellowish green. Low-lying clouds circling inside the hexagonal feature appear as muted orange color. A second, smaller vortex pops out in teal at the lower right of the image. The rings of Saturn appear in vivid blue at the top right.

The images were taken with Cassini's wide-angle camera using a combination of spectral filters sensitive to wavelengths of near-infrared light. The images filtered at 890 nanometers are projected as blue. The images filtered at 728 nanometers are projected as green, and images filtered at 752 nanometers are projected as red. At Saturn, this scheme means colors correlate to different altitudes in the planet's polar atmosphere: red indicates deep, while green shows clouds that are higher in altitude. High clouds are typically associated with locations of intense upwelling in a storm. These images help scientists learn the distribution and frequencies of such storms. The rings are bright blue in this color scheme because there is no methane gas between the ring particles and the camera. #nasa #jpl #cassini #saturn

The spinning vortex of Saturn's north polar storm resembles a deep red rose of giant proportions surrounded by green foliage in this false-color image from NASA's Cassini spacecraft. Measurements have sized the eye at a staggering 1,250 miles (2,000 kilometers) across with cloud speeds as fast as 330 miles per hour (150 meters per second). This image is among the first sunlit views of Saturn's north pole captured by Cassini's imaging cameras. When the spacecraft arrived in the Saturnian system in 2004, it was northern winter and the north pole was in darkness. Saturn's north pole was last imaged under sunlight by NASA's Voyager 2 in 1981; however, the observation geometry did not allow for detailed views of the poles. Consequently, it is not known how long this newly discovered north-polar hurricane has been active. #NASA #JPL #space #Saturn

This image of Saunders Island and Wolstenholme Fjord with Kap Atholl in the background was taken during an Operation IceBridge survey flight in April, 2013. Sea ice coverage in the fjord ranges from thicker, white ice seen in the background, to thinner grease ice and leads showing open ocean water in the foreground.

In March 2013, NASA's Operation IceBridge scientists began another season of research activity over Arctic ice sheets and sea ice. IceBridge, a six-year NASA mission, is the largest airborne survey of Earth's polar ice ever flown. It will yield an unprecedented three-dimensional view of Arctic and Antarctic ice sheets, ice shelves and sea ice. These flights will provide a yearly, multi-instrument look at the behavior of the rapidly changing features of the Greenland and Antarctic ice.
