Ten years ago, on Dec. 30, 2000, NASA's Cassini spacecraft made its closest approach to Jupiter on its way to orbiting Saturn. The main purpose was to use the gravity of the largest planet in our solar system to slingshot Cassini towards Saturn, its ultimate destination. But the encounter with Jupiter, Saturn's gas-giant big brother, also gave the Cassini project a p

Technicians in the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida are making such good progress with X-ray type image scans of space shuttle Discovery's external fuel tank that they expect to finish the job today, a day ahead of schedule. The team has been using a refined method of gathering the computed radiography scans of all 108 support beams

One of the greatest challenges that NASA faces in incorporating advanced technologies into future missions is bridging the mid-Technology Readiness Level (TRL 3-6) gap between early conceptual studies and infusion of a new technology onto the critical path of a science or exploration mission. Maturing a space technology to flight readiness status through relevant env

Snows are finally winding down in New England today, Dec. 27, as a powerful low pressure system brought blizzard conditions from northern New Jersey to Maine over Christmas weekend. The GOES-13 satellite captured an image of the low's center off the Massachusetts coast and saw the snowfall left behind. The Geostationary Operational Environmental Satellite called GOES

A rock-zapping laser instrument on NASA's next Mars rover has roots in a demonstration that Roger Wiens saw 13 years ago in a colleague's room at Los Alamos National Laboratory in New Mexico. The Chemistry and Camera (ChemCam) instrument on the rover Curiosity can hit rocks with a laser powerful enough to excite a pinhead-size spot into a glowing, ionized gas. ChemCa

On Dec. 16, 2010, NASA's Mars Exploration Rover Opportunity reached a crater about the size of a football field—some 90 meters (295 feet) in diameter. The rover team plans to use cameras and spectrometers during the next several weeks to examine rocks exposed at the crater, informally named "Santa Maria."A mosaic of image frames taken by Opportunity's navigation cam

NASA has taken the next step toward a new generation of Deep Space Network antennas. A $40.7 million contract with General Dynamics SATCOM Technologies, San Jose, Calif., covers implementation of two additional 34-meter (112-foot) antennas at Canberra, Australia. This is part of Phase I of a plan to eventually retire the network's aging 70-meter-wide (230-foot-wide)

NASA and Pratt & Whitney Rocketdyne have successfully completed the heart of the J-2X upper stage rocket engine - the turbomachinery assemblies - for the first development engine off the production line.The engine's turbomachinery consists of two turbopumps, each part pump and part turbine.

Christmas Eve, 1968. As one of the most turbulent, tragic years in American history drew to a close, millions around the world were watching and listening as the Apollo 8 astronauts -- Frank Borman, Jim Lovell and Bill Anders -- became the first humans to orbit another world. As their command module floated above the lunar surface, the astronauts beamed back images o

Lots of questions are coming in about the best times to view this around the world. Here's a summary from our astronomers below: "Early in the morning on Dec. 21, a total lunar eclipse will be visible to sky watchers around the world. The eclipse is visible across all of North America - for viewers in western states, the eclipse actually begins late in the evening of

Two satellite instruments aboard NASA's Solar Radiation & Climate Experiment (SORCE) mission - the Total Solar Irradiance Monitor (TIM) and the Solar Irradiance Monitor (SIM) - have made daily measurements of the sun's brightness since 2003. The two instruments are part of an ongoing effort to monitor variations in solar output that could affect Earth's climate.

The 33-year odyssey of NASA's Voyager 1 spacecraft has reached a distant point at the edge of our solar system where there is no outward motion of solar wind. Now hurtling toward interstellar space some 17.4 billion kilometers (10.8 billion miles) from the sun, Voyager 1 has crossed into an area where the velocity of the hot ionized gas, or plasma, emanating directl

On August 1, 2010, an entire hemisphere of the sun erupted. Filaments of magnetism snapped and exploded, shock waves raced across the stellar surface, billion-ton clouds of hot gas billowed into space. Astronomers knew they had witnessed something big.It was as big as it may have shattered old ideas about solar activity. "The August 1st event really opened our eyes,"

Astronomers have caught sight of an unusual galaxy that has illuminated new details about a celestial "sandbar" connecting two massive islands of galaxies. The research was conducted in part with NASA's Spitzer Space Telescope.These "sandbars," or filaments, are known to span vast distances between galaxy clusters and form a lattice-like structure known as the cosmic

A space shuttle main engine burns at 6,000 degrees F, but the outside of the nozzle remains cool to the touch. Prior to launch, sometimes it even frosts over. The nozzle technology that allows a finger-width of ridged metal to contain and steer flames that would boil iron is just one of the scores of innovations designers came up with for the engines three decades ag

Active sunspot 1121 has unleashed one of the brightest x-ray solar flares in years, an M5.4-class eruption.Radiation from the flare created a wave of ionization in Earth's upper atmosphere that altered the propagation of low-frequency radio waves. There was, however, no bright CME hurled in our direction, so the event is unlikely to produce auroras in the nights ahea

During the encounter, the spacecraft and comet whisked past each other at a speed of 12.3 kilometers per second (27,560 miles per hour). The spacecraft came within about 700 kilometers (435 miles) of the comet's nucleus at the time of closest approach.The video clip of the flyby is comprised of 40 frames taken from the spacecraft's Medium-Resolution Instrument during
