NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft is nearing its scheduled September 21st insertion into Martian orbit after completing a 10-month interplanetary journey of 442 million miles (711 million kilometers).

Flight Controllers at Lockheed Martin Space Systems in Littleton, Colorado, will be responsible for the health and safety of the spacecraft throughout the process. The spacecraft’s mission timeline will place the spacecraft in orbit at approximately 6:50pm PDT (9:50pm EDT).

NASA's MAVEN spacecraft is quickly approaching Mars on a mission to study its upper atmosphere. When it arrives on September 21, 2014, MAVEN's winding journey from Earth will culminate with a dramatic engine burn, pulling the spacecraft into an elliptical orbit.

NASA reports Small Asteroid 2014 RC to Pass Close, but Safely past Earth

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A small asteroid, designated 2014 RC, will safely pass very close to Earth on Sunday, September 7th, 2014.

At the time of closest approach, based on current calculations to be about 2:18pm EDT (11:18am PDT / 18:18 UTC), the asteroid will be roughly over New Zealand.

From its reflected brightness, astronomers estimate that the asteroid is about 60 feet (20 meters) in size.

This graphic depicts the passage of asteroid 2014 RC past Earth on September 7, 2014. At time of closest approach, the space rock will be about one-tenth the distance from Earth to the moon. Times indicated on the graphic are Universal Time. (NASA/JPL-Caltech)

NASA reports International Space Station to get 3-D Printer built to work in Microgravity

NASA - National Aeronautics and Space AdministrationHouston, TX – Riddle: It’s the size of a small microwave, and it may alleviate the need for NASA astronauts to wait for resupply ships to arrive at the International Space Station to get some essential items.

Answer: A 3-D printer — the first ever to be flown to space. And it could change the way NASA does business aboard the space station.

The 3-D Printing In Zero-G Technology Demonstration (3-D Printing In Zero-G), led out of NASA’s Marshall Space Flight Center in Huntsville, Alabama, provided a Small Business Innovation Research (SBIR) award to Made In Space Inc. to build the first 3-D printer for operation in microgravity. It is scheduled to launch to the station aboard the SpaceX-4 resupply mission.

Mike Snyder and Jason Dunn, both from Made In Space, assemble the 3-D printer that will fly to the International Space Station in the company's cleanroom. (Made In Space)

NASA’s New Horizons spacecraft passes Neptune’s Orbit on it’s way to Pluto

 

Written by Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s Pluto-bound New Horizons spacecraft has traversed the orbit of Neptune. This is its last major crossing en route to becoming the first probe to make a close encounter with distant Pluto on July 14th, 2015.

The sophisticated piano-sized spacecraft, which launched in January 2006, reached Neptune’s orbit — nearly 2.75 billion miles from Earth — in a record eight years and eight months. New Horizons’ milestone matches precisely the 25th anniversary of the historic encounter of NASA’s Voyager 2 spacecraft with Neptune on August 25th, 1989.

NASA's Pluto-bound New Horizons spacecraft captured this view of the giant planet Neptune and its large moon Triton on July 10, 2014, from a distance of about 2.45 billion miles (3.96 billion kilometers) - more than 26 times the distance between the Earth and sun. The 967-millisecond exposure was taken with the New Horizons telescopic Long-Range Reconnaissance Imager (LORRI).

NASA’s Orbiting Carbon Observatory-2 achieves final orbit and begins sending data

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Just over a month after launch, the Orbiting Carbon Observatory-2 (OCO-2) — NASA’s first spacecraft dedicated to studying atmospheric carbon dioxide — has maneuvered into its final operating orbit and produced its first science data, confirming the health of its science instrument.

Atmospheric carbon dioxide is the leading human-produced greenhouse gas responsible for warming our world.

NASA reports Rosetta spacecraft arrives at Comet 67P/Churyumov-Gerasimenko

 

Written by Tony Phillips

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Today, after a decade-long journey chasing its target, the European Space Agency’s Rosetta probe, carrying three NASA instruments, became the first spacecraft to rendezvous with a comet, 67P/Churyumov-Gerasimenko.

“After 10 years, five months and four days travelling towards our destination, looping around the sun five times and clocking up 6.4 billion kilometers, we are delighted to announce finally we are here,” said Jean-Jacques Dordain, ESA’s director General.

NASA releases new image of Rosetta Spacecraft’s target Comet

NASA - National Aeronautics and Space AdministrationWashington, D.C. – As the ESA’s Rosetta spacecraft closes to within 1000 km of Comet 67P/Churyumov-Gerasimenko, the Rosetta science team has released a new image and made the first temperature measurements of the comet’s core.  The temperature data show that 67P is too hot to be covered in ice and must instead have a dark, dusty crust.

The new image was acquired on August 1st at 02:48 UTC by the OSIRIS Narrow Angle Camera onboard Rosetta at a distance of approximately 1000 km. It shows the rough surface of the double-lobed core in amazing detail.

NASA’s Cassini spacecraft has found 101 distinct Geysers on Saturn’s Icy Moon Enceladus

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Scientists using mission data from NASA’s Cassini spacecraft have identified 101 distinct geysers erupting on Saturn’s icy moon Enceladus. Their analysis suggests it is possible for liquid water to reach from the moon’s underground sea all the way to its surface.

These findings, and clues to what powers the geyser eruptions, are presented in two articles published in the current online edition of the Astronomical Journal.

This view looks across the geyser basin of Saturn's moon Enceladus, along fractures spewing water vapor and ice particles into space. Cassini scientists have pinpointed the source locations of about 100 geysers and gained new insights into what powers them. (NASA/JPL-Caltech/SSI)

NASA’s Opportunity Mars rover sets Off World Driving Distance Record

 

Written by Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s Opportunity Mars rover, which landed on the Red Planet in 2004, now holds the off-Earth roving distance record after accruing 25 miles (40 kilometers) of driving, and is not far from completing the first extraterrestrial marathon. The previous record was held by the Soviet Union’s Lunokhod 2 rover.

“Opportunity has driven farther than any other wheeled vehicle on another world,” said Mars Exploration Rover Project Manager John Callas, of NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California. “This is so remarkable considering Opportunity was intended to drive about one kilometer and was never designed for distance.”

NASA's Mars Exploration Rover Opportunity, working on Mars since January 2004, passed 25 miles of total driving on July 27, 2014.

NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) discovers Comet that looked like an Asteroid

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Comet C/2013 UQ4 (Catalina) has been observed by NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) spacecraft just one day after passing through its closest approach to the sun.

The comet glows brightly in infrared wavelengths, with a dust tail streaking more than 62,000 miles (100,000 kilometers) across the sky. Its spectacular activity is driven by the vaporization of ice that has been preserved from the time of planet formation 4.5 billion years ago.
