F-35B
STOVL-mode Flight
Mar. 12,
2010
The first
Lockheed Martin [NYSE:LMT] F-35B Lightning II stealth fighter
passes overhead at 40 knots (46 mph) prior to a slow landing at
Naval Air Station Patuxent River, Md., on Wednesday, March 10.
The flight was one of the last missions before the aircraft's
first vertical landing, and confirmed the jet's power and
controllability at very low speeds.

Saturn's moon Mimas peeks out from behind the night
side of the larger moon Dione in this Cassini image captured
during the spacecraft's Dec. 12, 2011, flyby of Dione. Dione is
698 miles, or 1,123 kilometers, across and its day side dominates
the view on the right of the image. Smaller Mimas is on the left
and measures 246 miles, or 396 kilometers, across

NASA
has a bold mandate to launch a new journey of innovation and
discovery. As we seek to explore far beyond earth, we must invest
in critical knowledge and capabilities to enable this journey.

Composition

Sand
dunes are among the most widespread aeolian (wind-formed)
features present on Mars. Their spatial distribution and
morphology are affected by changes in wind direction and wind
strength. Patterns of dune erosion and deposition provide insight
into the sedimentary history of the surrounding terrain.

Here we see
three views of an image collected during MESSENGER's first flyby
of Mercury in January 2008. The top two images have had a harsh
contrast stretch applied, to emphasize portions of the image with
low signal levels. Notice that in the top left image there are
bright streaks in the sky that extend from the edge of the planet
toward the bottom of the image.

The
Helix Nebula
NEW
Jan.
19, 2012
The
Helix Nebula is one of the closest and most remarkable examples
of a planetary nebula. It lies in the constellation of Aquarius
(The Water Bearer), about 700 light-years away from Earth. This
strange object formed when a star like the Sun was in the final
stages of its life. Unable to hold onto its outer layers, the
star slowly shed shells of gas that became the nebula. It is
evolving to become a white dwarf star and appears as the tiny
blue dot seen at the center of the image.

LRO:
Mapping Our Future
May.
30, 2009
The
Lunar Reconnaissance Orbiter (LRO) is the first mission in NASA's
planned return to the moon. LRO is an unmanned mission to create
the comprehensive atlas of the moon's features and resources
necessary to design all future lunar exploration efforts. LRO
focuses on the selection of safe landing sites, identification of
lunar resources and the study of how lunar radiation will affect
humans.

CERN,
the European Organization for Nuclear Research, is one of the
world’s largest and most respected centers for scientific
research. We conduct fundamental research in physics to study the
basic constituents of matter — the elementary particles. By
studying what happens when very energetic particles collide,
physicists can learn more about the laws of nature.

galaxy / NGC 3628
May
11, 2010
NGC 3628 is an unbarred spiral galaxy about 35
million light-years away in the constellation Leo. It was
discovered by William Herschel in 1784. It has an approximately
300,000 light-years long tidal tail. NGC 3628 along with M65 and
M66 form the famous Leo Triplet, a small group of galaxies. Its
most conspicuous feature is the broad and obscuring band of dust
located along the outer edge of its spiral arms, effectively
transecting the galaxy to our view. By: Urban Observatory / John
