NASA’s Ebb and Flow spacecraft on final decent to Moon Impact

NASA - National Aeronautics and Space AdministrationPasadena, CA – The lunar twins of NASA’s Gravity Recovery and Interior Laboratory (GRAIL) mission have each completed a rocket burn that has sealed their fate. The burns modified the orbit of the formation-flying spacecraft.

Over the next three days, this new orbit will carry the twins lower and lower over the moon’s surface. On Monday afternoon, December 17th, at about 2:28pm PST (5:28pm EST), their moon-skimming will conclude when a portion of the lunar surface – an unnamed mountain near the natural satellite’s north pole – rises higher than their orbital altitude.

NASA’s GRAIL Lunar Probes to impact the Moon’s Surface December 17th

NASA - National Aeronautics and Space AdministrationPasadena, CA – Twin lunar-orbiting NASA spacecraft that have allowed scientists to learn more about the internal structure and composition of the moon are being prepared for their controlled descent and impact on a mountain near the moon’s north pole at about 2:28pm PST (5:28pm EST) Monday, December 17th.

Ebb and Flow, the Gravity Recovery and Interior Laboratory (GRAIL) mission probes, are being sent purposely into the lunar surface because their low orbit and low fuel levels preclude further scientific operations. The duo’s successful prime and extended science missions generated the highest resolution gravity field map of any celestial body. The map will provide a better understanding of how Earth and other rocky planets in the solar system formed and evolved.

NASA - National Aeronautics and Space AdministrationPasadena, CA – Twin NASA probes orbiting Earth’s moon have generated the highest resolution gravity field map of any celestial body.

The new map, created by the Gravity Recovery and Interior Laboratory (GRAIL) mission, is allowing scientists to learn about the moon’s internal structure and composition in unprecedented detail. Data from the two washing machine-sized spacecraft also will provide a better understanding of how Earth and other rocky planets in the solar system formed and evolved.

NASA’s GRAIL Spacecraft returns First Student-Selected Moon Images

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – One of two NASA spacecraft orbiting the moon has beamed back the first student-requested pictures of the lunar surface from its onboard camera. Fourth grade students from the Emily Dickinson Elementary School in Bozeman, MT, received the honor of making the first image selections by winning a nationwide competition to rename the two spacecraft.

The image was taken by the MoonKam, or Moon Knowledge Acquired by Middle school students.

This image of the far side of the lunar surface, with Earth in the background, was taken by the MoonKAM system board the Ebb spacecraft as part of the first image set taken from lunar orbit from March 15th - 18th, 2012. (NASA/Caltech-JPL/MIT/SRS)

Currahees stay connected on Mother’s Day

Task Force Currahee Public Affairs

The CurraheesFort Campbell KY, 101st Airborne DivisionPaktika Province, Afghanistan – Each day begins much like the last for the Task Force Currahee Soldiers from 4th Brigade Combat Team, 101st Airborne Division, who observed Mother’s Day though continents away from their own mothers and children while deployed to Paktika Province, Afghanistan.

While the Currahees are active in the fight, each uses various communication channels to stay connected to their mothers and children.

“I stay connected with my mother and daughter through e-mail and morale phone calls,” said U.S. Army 1st Lt. Monica M. Baker, the personnel officer-in-charge from Headquarters and Headquarters Battery, 4th Battalion, 320th Field Artillery Regiment, 4th Brigade Combat Team, 101st Airborne Division and native of Tampa, FL. “I also send letters and cards to my daughter. We often forget how exciting it is to receive a letter in the mail. My daughter loves to check the mail, and gets so excited when she sees a card from mommy with her name on it.” «Read the rest of this article»
