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.”

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 - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Mars Curiosity rover has reached the Red Planet’s Mount Sharp, a Mount-Rainier-size mountain at the center of the vast Gale Crater and the rover mission’s long-term prime destination.

“Curiosity now will begin a new chapter from an already outstanding introduction to the world,” said Jim Green, director of NASA’s Planetary Science Division at NASA Headquarters in Washington. “After a historic and innovative landing along with its successful science discoveries, the scientific sequel is upon us.”

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 Spitzer Space Telescope observes Asteroids circling a Young Star collide

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Spitzer Space Telescope has spotted an eruption of dust around a young star, possibly the result of a smashup between large asteroids. This type of collision can eventually lead to the formation of planets.

Scientists had been regularly tracking the star, called NGC 2547-ID8, when it surged with a huge amount of fresh dust between August 2012 and January 2013.

“We think two big asteroids crashed into each other, creating a huge cloud of grains the size of very fine sand, which are now smashing themselves into smithereens and slowly leaking away from the star,” said lead author and graduate student Huan Meng of the University of Arizona, Tucson.

This artist's concept shows the immediate aftermath of a large asteroid impact around NGC 2547-ID8, a 35-million-year-old sun-like star thought to be forming rocky planets. (NASA/JPL-Caltech)

NASA reports Mars Curiosity rover will not drill rock “Bonanza King” because of instablity

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Evaluation of a pale, flat Martian rock as the potential next drilling target for NASA’s Curiosity Mars rover determined that the rock was not stable enough for safe drilling.

The rock, called “Bonanza King,” moved slightly during the mini-drill activity on Wednesday, at an early stage of this test, when the percussion drill impacted the rock a few times to make an indentation.

This image from the front Hazcam on NASA's Curiosity Mars rover shows the rover's drill in place during a test of whether the rock beneath it, "Bonanza King," would be an acceptable target for drilling to collect a sample. Subsequent analysis showed the rock budged during the Aug. 19, 2014, test. (NASA/JPL-Caltech)

NASA’s Curiosity Mars rover gets ready to drill it’s fourth rock on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The team operating NASA’s Curiosity Mars rover has chosen a rock that looks like a pale paving stone as the mission’s fourth drilling target, if it passes engineers’ evaluation.

They call it “Bonanza King.”

It is not at the “Pahrump Hills” site the team anticipated the rover might reach by mid-August. Unexpected challenges while driving in sand prompted the mission to reverse course last week after entering a valley where ripples of sand fill the floor and extend onto sloping margins.

In this image from NASA's Curiosity Mars rover looking up the ramp at the northeastern end of "Hidden Valley," a pale outcrop including drilling target "Bonanza King" is at the center of the scene. (NASA/JPL-Caltech)

NASA says Comet Siding Spring and Mars’ Atmospheres may Collide in October

 

Written by Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – On October 19th, 2014, Comet Siding Spring will pass by Mars only 132,000 km away–which would be like a comet passing about 1/3 of the distance between Earth and the Moon.

The nucleus of the comet won’t hit Mars, but there could be a different kind of collision.

“We hope to witness two atmospheres colliding,” explains David Brain of the University of Colorado’s Laboratory for Atmospheric and Space Physics (LASP). “This is a once in a lifetime event!”

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Low-Density Supersonic Decelerator (LDSD) project successfully flew a rocket-powered, saucer-shaped test vehicle into near-space in late June from the U.S. Navy’s Pacific Missile Range Facility on Kauai, Hawaii.

The goal of this experimental flight test, the first of three planned for the project, was to determine if the balloon-launched, rocket-powered, saucer-shaped, design could reach the altitudes and airspeeds needed to test two new breakthrough technologies destined for future Mars missions.

NASA’s Mars Odyssey spacecraft adjusts orbit in lieu of Comet Siding Spring Flyby

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Mars Odyssey spacecraft has successfully adjusted the timing of its orbit around Mars as a defensive precaution for a comet’s close flyby of Mars on October 19th, 2014.

The orbiter fired thrusters for five and a half seconds on Tuesday, August 5th. The maneuver was calculated to place the orbiter behind Mars during the half hour on the flyby date when dust particles released from comet C/2013 A1 Siding Spring are most likely to reach Mars.
