NASA - National Aeronautics and Space AdministrationPasadena, CA – The High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter captured views of comet C/2013 A1 Siding Spring while that visitor sped past Mars on Sunday (October 19th), yielding information about its nucleus.

The images are the highest-resolution views ever acquired of a comet coming from the Oort Cloud at the fringes of the solar system.

These images were taken of comet C/2013 A1 Siding Spring by NASA's Mars Reconnaissance Orbiter on Oct. 19, 2014, during the comet's close flyby of Mars and the spacecraft. (NASA/JPL-Caltech/University of Arizona)

NASA - National Aeronautics and Space AdministrationPasadena, CA – The longest-lived robot ever sent to Mars came through its latest challenge in good health, reporting home on schedule after sheltering behind Mars from possible comet dust.

NASA’s Mars Odyssey was out of communications with Earth, as planned, while conducting observations of comet C/2013 A1 Siding Spring on Sunday, October 19th, as the comet flew near Mars.

NASA’s Opportunity Rover takes picture of ‘Wdowiak Ridge’ on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The latest fieldwork site for NASA’s Mars Exploration Rover Opportunity, which has been examining a series of Martian craters since 2004, is on the slope of a prominent hill jutting out of the rim of a large crater and bearing its own much smaller crater. It’s called “Wdowiak Ridge.”

“Wdowiak Ridge sticks out like a sore thumb. We want to understand why this ridge is located off the primary rim of Endeavour Crater and how it fits into the geologic story of this region,” said Opportunity science-team member Jim Rice of the Planetary Science Institute, Tucson, Arizona.

NASA’s MAVEN spacecraft to investigate disappearance of Mars’ atmosphere

 

Written by Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – After 10-month voyage across more than 400 million miles of empty space, NASA’s MAVEN spacecraft reached Mars on September 21st 2014. Less than 8 hours later, the data started to flow.

“Our Imaging Ultraviolet Spectrograph (IUVS) obtained these false-color images of Mars on September 22nd,” says Nick Schneider who leads the instrument team at the University of Colorado. “They trace the distribution of hydrogen and oxygen in the Martian atmosphere.”

Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s extensive fleet of science assets, particularly those orbiting and roving Mars, have front row seats to image and study a once-in-a-lifetime comet flyby on Sunday, October 19th.

Comet C/2013 A1, also known as comet Siding Spring, will pass within about 87,000 miles (139,500 kilometers) of the Red Planet — less than half the distance between Earth and our moon and less than one-tenth the distance of any known comet flyby of Earth.

NASA’s Mars Rover program laser technology being adapted to find Gas Leaks on Earth

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – In collaboration with NASA’s Jet Propulsion Laboratory in Pasadena, California, Pacific Gas and Electric Company (PG&E) announced that it is testing state-of-the-art technology adapted from NASA’s Mars rover program.

Originally designed to find methane on the Red Planet, this laser-based technology is lightweight and has superior sensitivity to methane, a major component of natural gas.

NASA’s GRAIL mission data reveals ‘Ocean of Storms’ region of Earth’s Moon formed from ancient rift valleys

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Using data from NASA’s Gravity Recovery and Interior Laboratory (GRAIL), mission scientists have solved a lunar mystery almost as old as the moon itself.

Early theories suggested the craggy outline of a region of the moon’s surface known as Oceanus Procellarum, or the Ocean of Storms, was caused by an asteroid impact. If this theory had been correct, the basin it formed would be the largest asteroid impact basin on the moon.

NASA reports Rosetta Spacecraft to release Philae Lander to Comet’s surface November 12th

 

Written by DC Agle/Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The European Space Agency’s Rosetta mission will deploy its lander, Philae, to the surface of comet 67P/Churyumov-Gerasimenko on November 12th.

Rosetta is an international mission spearheaded by the European Space Agency with support and instruments provided by NASA.

Philae’s landing site, currently known as Site J, is located on the smaller of the comet’s two “lobes,” with a backup site on the larger lobe. The sites were selected just six weeks after Rosetta’s August 6th arrival at the comet, following the spacecraft’s 10-year journey through the solar system.

NASA’s Mars Curiosity rover takes first drill sample from Mount Sharp

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Curiosity Mars rover has collected its first taste of the layered mountain whose scientific allure drew the mission to choose this part of Mars as a landing site.

Late Wednesday, September 24th, the rover’s hammering drill chewed about 2.6 inches (6.7 centimeters) deep into a basal-layer outcrop on Mount Sharp and collected a powdered-rock sample. Data and images received early Thursday at NASA’s Jet Propulsion Laboratory, Pasadena, California, confirmed success of this operation. The powder collected by the drilling is temporarily held within the sample-handling mechanism on the rover’s arm.

This image from the Mars Hand Lens Imager (MAHLI) camera on NASA's Curiosity Mars rover shows the first sample-collection hole drilled in Mount Sharp, the layered mountain that is the science destination of the rover's extended mission. (NASA/JPL-Caltech/MSSS)

NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft enters Mars Orbit

 

Written by Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft successfully entered Mars’ orbit at 10:24pm EDT Sunday, September 21st, where it now will prepare to study the Red Planet’s upper atmosphere as never done before. MAVEN is the first spacecraft dedicated to exploring the tenuous upper atmosphere of Mars.

“As the first orbiter dedicated to studying Mars’ upper atmosphere, MAVEN will greatly improve our understanding of the history of the Martian atmosphere, how the climate has changed over time, and how that has influenced the evolution of the surface and the potential habitability of the planet,” said NASA Administrator Charles Bolden. “It also will better inform a future mission to send humans to the Red Planet in the 2030s.”
