Topic: MAVENWritten by Guy Webster
Data from observations carried out by NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) mission, NASA’s Mars Reconnaissance Orbiter (MRO), and a radar instrument on the European Space Agency’s (ESA’s) Mars Express spacecraft have revealed that debris from the comet added a temporary and very strong layer of ions to the ionosphere, the electrically charged layer high above Mars. ![]() This artist’s concept depicts the Imaging Ultraviolet Spectrograph (IUVS) on NASA’s MAVEN spacecraft scanning the upper atmosphere of Mars. IUVS uses limb scans to map the chemical makeup and vertical structure across Mars’ upper atmosphere. (NASA/Univ. of Colorado) «Read the rest of this article» Sections: Technology | No Comments
NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft enters Mars OrbitWritten by Tony Phillips
“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.” «Read the rest of this article» Sections: Technology | No Comments
NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft ready to enter Mars orbitWritten by Izumi Hansen and Elizabeth Zubritsky
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. «Read the rest of this article» Sections: Technology | No Comments
NASA’s Mars Reconnaissance Orbiter, Odyssey Orbiter, MAVEN spacecraft ready for Comet C/2013 A1 flybyWritten by Dwayne Brown
The comet’s nucleus will miss Mars by about 82,000 miles (132,000 kilometers), shedding material hurtling at about 35 miles (56 kilometers) per second, relative to Mars and Mars-orbiting spacecraft. At that velocity, even the smallest particle — estimated to be about one-fiftieth of an inch (half a millimeter) across — could cause significant damage to a spacecraft. ![]() This graphic depicts the orbit of comet C/2013 A1 Siding Spring as it swings around the sun in 2014. On Oct. 19, the comet will have a very close pass at Mars. Its nucleus will miss Mars by about 82,000 miles (132,000 kilometers). The comet’s trail of dust particles shed by the nucleus might be wide enough to reach Mars or might also miss it. «Read the rest of this article» Sections: Technology | No Comments
NASA’s MAVEN spacecraft to examine Solar Wind’s roll in Mars losing it’s AtmosphereWritten by Claire Saravia
One instrument aboard the spacecraft will study a special component of the Martian atmosphere to help solve this mystery. By studying ions, or small electrically charged particles, in and above the Red Planet’s tenuous atmosphere, the Solar Wind Ion Analyzer will help answer why Mars has gradually lost much of its atmosphere, developing into a frozen, barren planet. ![]() This artist’s concept shows the MAVEN spacecraft orbiting Mars.

NASA prepares Spacecraft for Comet Siding Spring’s flyby of MarsWritten by Guy Webster
On that date, comet 2013 A1 Siding Spring will buzz Mars about 10 times closer than any identified comet has ever flown past Earth. Spacecraft at Mars might get a good look at the nucleus of comet Siding Spring as it heads toward the closest approach, roughly 86,000 miles (138,000 kilometers) from the planet, give or take a few percent. ![]() This graphic depicts the orbit of comet C/2013 A1 Siding Spring as it swings around the sun in 2014. On Oct. 19, the comet will have a very close pass at Mars, just 86,000 miles ( 138,000 kilometers) from the planet. Although the nucleus will miss the planet, the comet’s coma of dust particles might envelop the Red Planet. (NASA/JPL-Caltech) «Read the rest of this article» Sections: Technology | No Comments
NASA’s Mars Curiosity Rover confirms that some Meteors that land on Earth are from MarsWritten by Guy Webster
A key new measurement of the inert gas argon in Mars’ atmosphere by Curiosity’s laboratory provides the most definitive evidence yet of the origin of Mars meteorites while at the same time providing a way to rule out Martian origin of other meteorites. ![]() This self-portrait of NASA’s Mars rover Curiosity combines 66 exposures taken by the rover’s Mars Hand Lens Imager (MAHLI) during the 177th Martian day, or sol, of Curiosity’s work on Mars (Feb. 3, 2013).

NASA’s Mars Curiosity Rover to celebrate First Year on Mars
“Successes of our Curiosity — that dramatic touchdown a year ago and the science findings since then — advance us toward further exploration, including sending humans to an asteroid and Mars,” said NASA Administrator Charles Bolden. “Wheel tracks now, will lead to boot prints later.” «Read the rest of this article» Sections: Technology | No Comments
NASA’s Mars Curiosity rover data reveals alot about Mars’ Atmosphere in the Past
Curiosity’s Sample Analysis at Mars (SAM) suite of laboratory instruments inside the rover has measured the abundances of different gases and different isotopes in several samples of Martian atmosphere. Isotopes are variants of the same chemical element with different atomic weights due to having different numbers of neutrons, such as the most common carbon isotope, carbon-12, and a heavier stable isotope, carbon-13. ![]() This picture shows a lab demonstration of the measurement chamber inside the Tunable Laser Spectrometer, an instrument that is part of the Sample Analysis at Mars investigation on NASA’s Curiosity rover.
