 The surface of Saturn's moon Dione is rendered in crisp detail against a
hazy, ghostly Titan. Visible in this image are hints of atmospheric
banding around Titan's north pole. T The image was taken in visible blue
light with the Cassini spacecraft narrow-angle camera on April 10,
2010. The
view was acquired at a distance of approximately 1.8 million kilometers
(1.1 million miles) from Dione and 2.7 million kilometers (1.7 million
miles) from Titan. Scale in the original image was 11 kilometers (7
miles) per pixel on Dione and 16 kilometers (10 miles) on Titan. The
image has been magnified by a factor of 1.5 and contrast-enhanced to aid
visibility. Image Credit: NASA/JPL/Space Science Institute

 This future aircraft design concept for supersonic flight over land
comes from the team led by the Lockheed Martin Corporation. The team's
simulation shows possibility for achieving overland flight by
dramatically lowering the level of sonic booms through the use of an
"inverted-V" engine-under wing configuration. Other revolutionary
technologies help achieve range, payload and environmental goals. This
supersonic cruise concept is among the designs presented in April 2010
to the NASA A... Continue reading...

 The International Astronomical Union (IAU) recently approved the name
Rachmaninoff for an intriguing double-ring basin on Mercury. This basin,
first imaged in its entirety during MESSENGER's third Mercury flyby,
was quickly identified as a feature of high scientific interest, because
of its fresh appearance, its distinctively colored interior plains, and
the extensional troughs on its floor. The basin's name honors the
Russian composer, pianist and conductor, Sergei Rachmaninoff
(1873-1... Continue reading...

 The Seagull nebula, seen in this infrared mosaic from NASA's Wide-field
Infrared Survey Explorer, or WISE, draws its common name from it
resemblance to a gull in flight. But it depends on your point of view.
When the image is rotated 180 degrees it bears a passing resemblance to a
galloping lizard -- or perhaps a dragon or a dinosaur. The image spans
an area about seven times as wide as the full moon, and three times as
high (3.55 by 1.37 degrees), straddling the border between the
cons... Continue reading...

 The Japan Aerospace Exploration Agency’s Hayabusa spacecraft streaked
across the sky like a saber of light through the clouds as it re-entered
Earth’s atmosphere over the Woomera Test Range in Australia. In
Kingoonya, the spacecraft’s re-entry was visible to the human eye
for only 15 seconds. Image Credit: NASA/Ed Schilling Continue reading...

 Today, our sun reaches its northernmost point in planet Earth's sky.
Called a solstice, the date traditionally marks a change of seasons --
from spring to summer in Earth's Northern Hemisphere and from fall to
winter in Earth's Southern Hemisphere. In this image from 2007, NASA's
Solar
TErrestrial RElations Observatory (STEREO) satellites provided the first
three-dimensional images of the sun. STEREO, a two-year mission that
launched October 2006, provided a unique and revolutionary vie... Continue reading...

WASHINGTON
-- A NASA-led research team has successfully demonstrated for the first
time elements of a prototype tsunami prediction system that quickly and
accurately assesses large earthquakes and estimates the size of
resulting tsunamis. After the magnitude 8.8 Chilean
earthquake on Feb. 27, a team led by Y. Tony Song of NASA's Jet
Propulsion Laboratory in Pasadena, Calif., used real-time data from the
agency's Global Differential GPS (GDGPS) network to successfully
predict the size of ... Continue reading...

 On June 18, 1983, a young physicist from California took her seat
aboard the space shuttle and launched into history. On that date, Sally
Ride became the first American woman in space as a mission specialist
on STS-7. In this image Ride monitors control panels from the pilot's
chair on the Flight Deck. Image Credit: NASA Continue reading...
