NASA - National Aeronautics and Space AdministrationPasadena, 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.

NASA’s Journey to Mars builds ground work for missions beyond our Solar System

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, 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.

NASA’s Global Land Ice Velocity Extraction project provides near real time view of Glacier movement

 

Written by Kate Ramsayer
NASA Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, 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.

The texture on the surface of flowing ice, such as Heimdal Glacier in southern Greenland, allows Landsat 8 to map nearly all the flowing ice in the world. (NASA/John Sonntag)

NASA’s Oceans Melting Greenland mission survey produces new data, maps of Greenland’s Glaciers

 

Written by Carol Rasmussen
NASA Earth Science News Team

NASA - National Aeronautics and Space AdministrationWashington, 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.

NASA’s Mars Reconnaissance Orbiter observes thawing Carbon Dioxide creating Channels on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, 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.

This sequence of three HiRISE images from NASA's Mars Reconnaissance Orbiter shows the growth of a branching network of troughs carved by thawing carbon dioxide over the span of three Martian years. This process may also form larger radially patterned channel features known as Martian "spiders." (NASA/JPL-Caltech/Univ. of Arizona)

New NASA Tracking Technology Could Help Track Firefighters inside Buildings

 

Written by Andrew Good
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, 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.

A test of a new tracking technology, which can be followed on a computer map. JPL may have solved a longstanding technology problem for firefighters: how do you track them inside of buildings, which often block radio signals? (Paul Wedig/DHS-Science and Technology Directorate.)

NASA looks to use Satellite Observations of Earth’s Magnetic Fields to Measure Ocean Heat

 

Written by Kate Ramsayer
NASA Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – As Earth warms, much of the extra heat is stored in the planet’s ocean — but monitoring the magnitude of that heat content is a difficult task.

A surprising feature of the tides could help, however. Scientists at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, are developing a new way to use satellite observations of magnetic fields to measure heat stored in the ocean.

NASA’s Juno Spacecraft has successful Flyby of Jupiter

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, 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.

NASA - National Aeronautics and Space AdministrationPasadena, CA – On Sunday, December 11th, at 9:04am PST (11:04am CST, 17:04 UTC) NASA’s Juno spacecraft will make its third science flyby of Jupiter.

At the time of closest approach (called perijove), Juno will be about 2,580 miles (4,150 kilometers) above the gas giant’s roiling cloud tops and traveling at a speed of about 129,000 mph (57.8 kilometers per second) relative to the planet. Seven of Juno’s eight science instruments will be energized and collecting data during the flyby.

NASA’s Curiosity Mars rover undergoes diagnostic tests on Drill Arm

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Curiosity Mars rover is studying its surroundings and monitoring the environment, rather than driving or using its arm for science, while the rover team diagnoses an issue with a motor that moves the rover’s drill.

Curiosity is at a site on lower Mount Sharp selected for what would be the mission’s seventh sample-collection drilling of 2016. The rover team learned December 1st that Curiosity did not complete the commands for drilling. The rover detected a fault in an early step in which the “drill feed” mechanism did not extend the drill to touch the rock target with the bit.

This Dec. 2, 2016, view from the Navigation Camera (Navcam) on the mast of NASA's Curiosity Mars Rover shows rocky ground within view while the rover was working at an intended drilling site called "Precipice" on lower Mount Sharp. (NASA/JPL-Caltech)
