Pasadena, CA – NASA’s Mars Odyssey orbiter, which has been in service at Mars since October 2001, put itself into safe mode — a protective standby status — on December 26th, while remaining in communication with Earth.
The Odyssey project team has diagnosed the cause — an uncertainty aboard the spacecraft about its orientation with regard to Earth and the sun — and is restoring the orbiter to full operations.

Pasadena, CA – This image, taken by the JunoCam imager on NASA’s Juno spacecraft, highlights the seventh of eight features forming a ‘string of pearls on Jupiter — massive counterclockwise rotating storms that appear as white ovals in the gas giant’s southern hemisphere.
Since 1986, these white ovals have varied in number from six to nine. There are currently eight white ovals visible.
Washington, D.C. – Humanity’s great leap into the space between the stars has, in a sense, already begun. NASA’s Voyager 1 probe broke through the sun’s magnetic bubble to touch the interstellar wind. Voyager 2 isn’t far behind. New Horizons shot past Pluto on its way to encounters with more distant dwarf worlds, the rubble at the solar system’s edge.
Closer to home, we’re working on techniques to help us cross greater distances. Astronauts feast on romaine lettuce grown aboard the International Space Station, perhaps a preview of future banquets en route to Mars, or to deep space.

Greenbelt, MD – Glaciers and ice sheets move in unique and sometimes surprising patterns, as evidenced by a new capability that uses satellite images to map the speed of flowing ice in Greenland, Antarctica and mountain ranges around the world.
With imagery and data from Landsat 8, a joint mission of NASA and the U.S. Geological Survey, scientists are providing a near-real-time view of every large glacier and ice sheet on Earth.
The NASA-funded Global Land Ice Velocity Extraction project, called GoLIVE, is a collaboration between scientists from the University of Colorado, the University of Alaska, and NASA’s Jet Propulsion Laboratory in Pasadena, California.

Washington, D.C. – NASA’s Oceans Melting Greenland (OMG) mission has released preliminary data on the heights of Greenland coastal glaciers from its first airborne campaign in March 2016.
The new data show the dramatic increase in coverage that the mission provides to scientists and other interested users. Finalized data on glacier surface heights, accurate within three feet (one meter) or less vertically, will be available by February 1st, 2017.

Pasadena, CA – Erosion-carved troughs that grow and branch during multiple Martian years may be infant versions of larger features known as Martian “spiders,” which are radially patterned channels found only in the south polar region of Mars.
Researchers using NASA’s Mars Reconnaissance Orbiter (MRO) report the first detection of cumulative growth, from one Martian spring to another, of channels resulting from the same thawing-carbon-dioxide process believed to form the spider-like features.

Pasadena, CA – In 1999, six career firefighters lost their lives responding to a five-alarm fire. They were part of a group of 73 dispatched to a smoke-filled warehouse in Worcester, Massachusetts. Lost inside the building’s tight corners, they were unable to find an exit before running out of oxygen.
Avoiding a tragedy like that has been a technical challenge for decades. In the outdoors, firefighters can use GPS to track one another, and radios to stay in communication. But when they move into a steel and concrete building, these technologies suddenly become unreliable.

Pasadena, CA – NASA confirmed Friday morning that all eight spacecraft of its latest Earth science mission are in good shape. The Cyclone Global Navigation Satellite System (CYGNSS) will provide scientists with advanced technology to see inside tropical storms and hurricanes as never before.
CYGNSS launched into orbit at 5:37am PST (8:37am EST) Thursday aboard an Orbital ATK air-launched Pegasus XL launch vehicle. The rocket was dropped and launched from Orbital’s Stargazer L-1011 aircraft, which took off from Cape Canaveral Air Force Station in Florida, over the Atlantic Ocean, off the coast of central Florida.

Pasadena, CA – At first glance, Ceres, the largest body in the main asteroid belt, may not look icy. Images from NASA’s Dawn spacecraft have revealed a dark, heavily cratered world whose brightest area is made of highly reflective salts — not ice.
But newly published studies from Dawn scientists show two distinct lines of evidence for ice at or near the surface of the dwarf planet. Researchers are presenting these findings at the 2016 American Geophysical Union meeting in San Francisco.

Pasadena, CA – NASA’s Juno mission completed a close flyby of Jupiter on Sunday, December 11th, its latest science orbit of the mission.
Seven instruments and the spacecraft’s JunoCam were operating during the flyby to collect data that is now being returned to Earth. Juno is currently in a 53-day orbit, and its next close flyby of Jupiter will occur on February 2nd, 2017.
On Sunday, December 11th, at 9:04am PST (12:04pm EST, 17:04 UTC) NASA’s Juno spacecraft will make its third flyby over Jupiter’s mysterious cloud tops.
