NASA’s Lunar Reconnaissance Orbiter prepares for Supermoon Eclipse

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – On the evening of September 27th, 2015, into the early morning of September 28th EDT, operators of NASA’s Lunar Reconnaissance Orbiter (LRO) will wait as Earth blots out the sun and the moon goes dark.

The flight operations team at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, have seen LRO safely through three lunar eclipses in about a year and a half. Although it is certainly not an ordinary night, science operations planner Dawn Myers at Goddard said the team knows the routine.

“We have a method and it works well,” she said. “It’s always stressful during the approach of the eclipse, but we follow the same procedures every time and we haven’t had any trouble.”

NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE) discovers Neon in Moon’s Atmosphere

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – The moon’s thin atmosphere contains neon, a gas commonly used in electric signs on Earth because of its intense glow. While scientists have speculated on the presence of neon in the lunar atmosphere for decades, NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft has confirmed its existence for the first time.

“The presence of neon in the exosphere of the moon has been a subject of speculation since the Apollo missions, but no credible detections were made,” said Mehdi Benna of NASA’s Goddard Space Flight Center in Greenbelt, Maryland and the University of Maryland, Baltimore County. “We were very pleased to not only finally confirm its presence, but to show that it is relatively abundant.”

NASA’S Lunar Reconnaissance Orbiter takes photos of LADEE’s impact crater on the Moon

 

Written by Nancy Neal-Jones

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA’S Lunar Reconnaissance Orbiter (LRO) spacecraft has spied a new crater on the lunar surface; one made from the impact of NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE) mission.

“The Lunar Reconnaissance Orbiter Camera (LROC) team recently developed a new computer tool to search Narrow Angle Camera (NAC) before and after image pairs for new craters, the LADEE impact event provided a fun test, said Mark Robinson, LROC principal investigator from Arizona State University in Tempe. “As it turns there were several small surface changes found in the predicted area of the impact, the biggest and most distinctive was within 968 feet (295 meters) of the spot estimated by the LADEE operations team. What fun!”

LRO has imaged the LADEE impact site on the eastern rim of Sundman V crater. The image was created by ratioing two images, one taken before the impact and another afterwards. The bright area highlights what has changed between the time of the two images, specifically the impact point and the ejecta. (NASA/Goddard/Arizona State University)

NASA to launch Lunar Atmosphere and Dust Environment Explorer (LADEE) to study Twilight Rays on the Moon

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Back in the 60s and 70s, Apollo astronauts circling the Moon saw something that still puzzles researchers today. About 10 seconds before lunar sunrise or lunar sunset, pale luminous streamers would pop up over the gray horizon. These “twilight rays” were witnessed by crew members of Apollo 8, 10, 15 and 17.

Back on Earth, we see twilight rays all the time as shafts of sunlight penetrate evening clouds and haze.  The “airless Moon” shouldn’t have such rays, yet the men of Apollo clearly saw them.
