Why would the surface of Titan light up with a blinding flash? The reason: a sunglint from liquid seas. Saturn's moon Titan has numerous smooth lakes of methane that, when the angle is right, reflect sunlight as if they were mirrors. Pictured here in false-color, the robotic Cassini spacecraft orbiting Saturn imaged the cloud-covered Titan last summer in different bands of cloud-piercing infrared light. This specular reflection was so bright it saturated one of Cassini's infrared cameras. Although the sunglint was annoying -- it was also useful. The reflecting regions confirm that northern Titan houses a wide and complex array of seas with a geometry that indicates periods of significant evaporation. During its numerous passes of our Solar System's most mysterious moon, Cassini has revealed Titan to be a world with active weather -- including times when it rains a liquefied version of natural gas. via NASA ift.tt/1z3XsyB

A New Moon joined giant sunspot group AR 2192 to dim the bright solar disk during Thursday's much anticipated partial solar eclipse. Visible from much of North America, the Moon's broad silhouette is captured in this extreme telephoto snapshot near eclipse maximum from Santa Cruz, California. About the size of Jupiter, the remarkable AR 2192 itself darkens a noticeable fraction of the Sun, near center and below the curved lunar limb. As the sunspot group slowly rotates across the Sun and out of view in the coming days its activity is difficult to forecast. But the timing of solar eclipses is easier to predict. The next will be a total solar eclipse on March 20, 2015. via NASA ift.tt/1skb2KM

NASA's Curiosity Mars rover can be seen at the "Pahrump Hills" area of Gale Crater in this view from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. Pahrump Hills is an outcrop at the base of Mount Sharp. The region contains sedimentary rocks that scientists believe formed in the presence of water. The location of the rover, with its shadow extending toward the upper right, is indicated with an inscribed rectangle. Figure A is an unannotated version of the image. North is toward the top. The view covers an area about 360 yards (330 meters) across. HiRISE made the observation on Dec. 13, 2014. At that time, Curiosity was near a feature called "Whale Rock." A map showing the rover's path for the weeks leading up to that date is at ift.tt/1DeDac2 . The inset map at ift.tt/16owOdk labels the location of Whale Rock and other features in the Pahrump Hills area. The bright features in the landscape are sedimentary rock and the dark areas are sand. The HiRISE team plans to periodically image Curiosity, as well as NASA's other active Mars rover, Opportunity, as the vehicles continue to explore Mars. This image is an excerpt from HiRISE observation ESP_039280_1755. Other image products from this observation are available at ift.tt/16owPha . The University of Arizona, Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp., Boulder, Colorado. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Reconnaissance Orbiter Project and Mars Science Laboratory Project for NASA's Science Mission Directorate, Washington.

Check this out from NASA -- Do you see the bat? It haunts this cosmic close-up of the eastern Veil Nebula. The Veil Nebula itself is a large supernova remnant, the expanding debris cloud from the death explosion of a massive star. While the Veil is roughly circular in shape and covers nearly 3 degrees on the sky toward the constellation of the Swan (Cygnus), the Bat Nebula, NGC 6995, spans only 1/2 degree, about the apparent size of the Moon. That translates to 12 light-years at the Veil's estimated distance, a reassuring 1,400 light-years from planet Earth. In the composite of image data recorded through broad and narrow band filters, emission from hydrogen atoms in the remnant is shown in red with strong emission from oxygen and nitrogen atoms shown in hues of blue. Of course, in the western part of the Veil lies another seasonal apparition: the Witch's Broom Nebula. (ift.tt/35yM1XY)
The NASA Tweet Up event held at NASA Headquarters July 21, 2009 in Washington, D.C. The focus of the Tweet Up was the STS-125 (Space Shuttle) Mission. K. Megan McArthur is a member of the STS-125 crew.An estimated crowd of 200 people who follow NASA's twitter feed were in attendance.
Early spring in the northern hemisphere is good season for aurora hunters. Near an equinox Earth's magnetic field is oriented to favor interactions with the solar wind that trigger the alluring glow of the northern lights. On March 28/29 the skies over Kaunispää Hill, Lapland, Finland did not disappoint. That night's expansive auroral curtains are captured in this striking panoramic view that covers a full 360 degrees. Local skywatchers were mesmerized by bright displays lasted throughout the dark hours, shimmering with colors easily visible to the naked eye. via NASA go.nasa.gov/1NfDzxg

Racing at Miller Motorsports Park NASA Round 6
If you are interested in wheel to wheel racing, then our competition racing program is for you. NASA has created racing programs that accommodate all sorts of popular vehicles with rules that encourage aftermarket modification. NASA has a class for almost any type of vehicle ranging from Production Sedans, Stock Cars, and Formula Cars. If you do not posses a competition license, NASA has programs that will allow you to participate in a racing school to become qualified to race. If you are currently racing with another recognized organization, NASA welcomes you to our program and accepts competition licenses from many different sanctioning bodies.

From the International Space Station, NASA astronaut Scott Kelly (stationcdrkelly on Instagram) took this photograph and posted it to social media on April 6, 2015. Kelly wrote, "Australia. You are very beautiful. Thank you for being there to brighten our day. #YearInSpace" Kelly and Russian Federal Space Agency (Roscosmos) cosmonaut Mikhail Kornienko began their one-year mission aboard the space station on March 27. Most expeditions to the space station last four to six months. By doubling the length of this mission, researchers hope to better understand how the human body reacts and adapts to long-duration spaceflight. Image Credit: NASA via NASA ift.tt/1DEGXSp
NASA has started an airborne science campaign to get a better understanding of what affects the composition of the atmosphere and the climate. The project is using specially equipped research planes.

NASA has built and is sending a set of high-tech legs up to the International Space Station for Robonaut 2 (R2), the station's robotic crewmember. The new legs are scheduled to launch on the SpaceX-3 commercial cargo flight to the International Space Station, scheduled to launch Monday, April 14 at 4:58 p.m. EDT from Cape Canaveral Air Force Station in Florida. These new legs, funded by NASA's Human Exploration and Operations and Space Technology mission directorates, will provide R2 the mobility it needs to help with regular and repetitive tasks inside and outside the space station. The goal is to free up the crew for more critical work, including scientific research. Once the legs are attached to the R2 torso, the robot will have a fully extended leg span of nine feet, giving it great flexibility for movement around the space station. Each leg has seven joints and a device on what would be the foot, called an "end effector," which allows the robot to take advantage of handrails and sockets inside and outside the station. A vision system for the end effectors also will be used to verify and eventually automate each limb's approach and grasp. > Read more Image Credit: NASA via NASA ift.tt/1gwd9GW
Taking part in the Safari 2000 project in Pietersburg, South Africa
SAFARI 2000 – Pietersberg, 2000
The Southern African Regional Science Initiative (SAFARI 2000) project was an international science initiative to study the linkages between land and atmosphere processes conducted from 1999-2001 in the southern African region. In addition, SAFARI 2000 examined the relationship of biogenic, pyrogenic, and anthropogenic emissions and the consequences of their deposition to the functioning of the biogeophysical and biogeochemical systems of southern Africa.
During September 2000 NASA flew an ER-2 out of Polokwane, also known as Pietersburg. The ER2 carried a number of imaging instruments and was accompanied by low level in situ measurements conducted from a University of Washington C-580. Flying took place over South Africa, Namibia, Botswana, Mozambique and Zambia. The project was supported and supplied by a USAF C-141 and K -135 from March AFB. The single seater ER-2 flew across the Atlantic from Recife Brazil.
