This observation from NASA's Mars Reconnaissance Orbiter shows the floor of a large impact crater in the southern highlands, north of the giant Hellas impact basin. Most of the crater floor is dark, with abundant small ripples of wind-blown material. However, a pit in the floor of the crater has exposed light-toned, fractured rock. The light-toned material appears fractured at several different scales. These fractures, called joints, result from stresses on the rock after its formation. Joint...

NASA's Swift satellite views Comet Lulin as it made it closest approach to Earth in February 2009. Lulin, like all comets, is a clump of frozen gases mixed with dust. These "dirty snowballs" cast off gas and dust whenever they venture near the sun. Comet Lulin, which is formally known as C/2007 N3, was discovered in 2008 by astronomers at Taiwan's Lulin Observatory. Lulin passed closest to Earth -- 38 million miles, or about 160 times farther than the moon -- late on the evening of Feb. 23, 2...

This image shows the effects of a giant black hole that has been flipped around twice, causing its spin axis to point in a different direction from before. The large optical image, from the Sloan Digital Sky Survey, is centered on a radio galaxy named 4C +00.58. The smaller image to the right shows a close-up view of this galaxy in X-rays (in gold) from the Chandra X-ray Observatory, and radio waves (in blue) from the Very Large Array.

At the center of 4C +00.58 is a supermassive black ho...

Children experience NASA from the inside during the annual "Take Your Children to Work Day" held each summer at NASA facilities across the country. Children get to see NASA facilities, participate in education activities and shadow their parents during the workday. They can also observe the agency's many different careers, learning about occupations as varied as engineering, graphic design, accounting, maintenance and many other professions. Pictured here, children explore the Exploration Exp...

One day homeowners everywhere may be protected from deadly carbon monoxide fumes, thanks to a device invented at NASA's Langley Research Center. The device uses a new class of low-temperature oxidation catalysts to convert carbon monoxide to non-toxic carbon dioxide at room temperature and also removes formaldehyde from the air. The catalysts initially were developed for research involving carbon dioxide lasers. Image Credit: NASA

On July 17, 1975, Cold War rivals America and the Soviet Union met in Earth orbit as American Apollo astronauts Tom Stafford, Vance Brand and Deke Slayton docked with Soviet Soyuz cosmonauts Aleksey Leonov and Valeriy Kubasov. During their joint mission, the astronauts and cosmonauts assembled this commemorative plaque in orbit as a symbol of the international cooperation. The American side is blue with English text, while the Soviet side is red with Russian text. Image Credit: NASA

On July 11, 2010, the new moon passed directly in front of the sun, causing a total solar eclipse in the South Pacific. In this image, the solar eclipse is shown in gray and white from a photo provided by the Williams College Expedition to Easter Island and was embedded with an image of the sun’s outer corona taken by the Large Angle Spectrometric Coronagraph (LASCO) on the SOHO spacecraft and shown in red false color. LASCO uses a disk to blot out the bright sun and the inner corona so tha...

On its way to a 2014 rendezvous with comet 67P/Churyumov-Gerasimenko, the European Space Agency's Rosetta spacecraft, with NASA instruments aboard, flew past asteroid Lutetia on Saturday, July 10. The instruments aboard Rosetta recorded the first close-up image of the biggest asteroid so far visited by a spacecraft. Rosetta made measurements to derive the mass of the object, understand the properties of the asteroid's surface crust, record the solar wind in the vicinity and look for evidence ...

A piece of NASA history landed at the Glenn Research Center's Visitor Center, now located at the Great Lakes Science Center in Cleveland, Ohio. The Apollo Command Module, used for the Skylab 3 mission in 1973, was moved successfully from Glenn to the Science Center on Tuesday, June 22. The module will be the focal point of the Visitor Center, which includes space and aeronautics artifacts, models and interactive experiences. The move was carefully planned to protect and preserve the module, w...

Taken in 1989 by Voyager 2 during its flyby of the Neptune system, this is a global color mosaic of Triton. The color was synthesized by combining high-resolution images taken through orange, violet and ultraviolet filters; these images were displayed as red, green, and blue images and combined to create this color version. With a radius about 22 percent smaller than Earth's moon, Triton is the largest satellite of Neptune and is one of the few bodies in the solar system known to have a nitro...

Spacecraft attempting to land on an unfamiliar surface need to perform a maneuver called “deep throttling" -- a step that allows the vehicle to precisely throttle down to perform a smooth, controlled landing. NASA and industry partners have demonstrated this type of engine control capability to help design a more reliable and robust descent engine that could be used to land space exploration vehicles on the moon, an asteroid or another planet. The Common Extensible Cryogenic Engine, also kn...

NASA's Mars Exploration Rover Opportunity used its navigation camera to take the images combined into this full 360-degree view of the rover's surroundings after a drive on the 2,220th Martian day, or sol, of its mission (April 22, 2010). Opportunity launched on July 7, 2003, on a mission slated to last 90 days, landing on Mars in January 2004. The rover has exceeded its mission parameters by more than 2,200 days as its exploration of the Red Planet continues. Opportunity took some of the com...

Like an Independence Day fireworks display, a young, glittering collection of stars looks like an aerial burst. The cluster is surrounded by clouds of interstellar gas and dust -- the raw material for new star formation. The nebula, located 20,000 light-years away in the constellation Carina, contains a central cluster of huge, hot stars, called NGC 3603. This environment is not as peaceful as it looks. Ultraviolet radiation and violent stellar winds have blown out an enormous cavity in the g...

Space shuttle Discovery and its seven-member crew launched at 2:38 p.m. EDT on July 4, 2006 to begin their journey to the International Space Station during the STS-121 mission. The shuttle made history as it was the first human-occupied spacecraft to launch on Independence Day. During the 12-day mission, the crew tested new equipment and procedures that increase the safety of the orbiters. It also performed maintenance on the space station and delivered supplies, equipment and a new Ex...

There are two possible explanations for this 'slingshot' in space: kickback by a triple black hole system, or the effects of gravitational waves produced after two supermassive black holes merged a few million years earlier. The discovery of this object comes from a large, multi-wavelength survey, known as the Cosmic Evolution Survey (COSMOS). This survey includes data from Chandra, HST, XMM- Newton, as well as ground-based observatories. Of the 2,600 X-ray sources found in COSMOS, only...

The Mercury 7 astronauts examine their 'couches.' Each astronaut's couch was molded to fit his body to help withstand the G-loads of the launch. Plaster casts of the astronauts were created in order to properly mold the couches. Left to right are Alan Sheppard, John Glenn, Walter Schirra, Scott Carpenter, Gordon Cooper, Deke Slayton, Gus Grissom and Bob Gilruth. Gilruth was director of the Space Task Group, which planned and managed the Mercury Project. Image Credit: NASA

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 kil...
