NASA Probes Smash Into Moon Mountain as Planned

NASA’s GRAIL project spacecrafts, Ebb and Flow, crash-landed on the surface of the moon yesterday afternoon. The impact had been pre-planned, and occurred as predicted at 5:28 pm December 17, 2012. The landing site has been named in honor of Sally Ride, the first U.S. woman in space and a member of the GRAIL mission team. “Sally was all about …

NASA Probes Prepare to Slam Into the Moon

NASA‘s Gravity Recovery and Interior Laboratory (GRAIL) probes today completed a burn that irreversibly altered their orbit and have begun skimming the surface of the moon. Over the weekend, the probes, named Ebb and Flow, will orbit ever closer to the surface of the moon. On Monday, December 17, at around 5:28 pm EST the probes will slam into the …

NASA to Crash GRAIL Probes Into the Moon

NASA this week detailed its plans to crash two lunar-orbiting probes into the moon next week. On Monday, December 17 at 5:28 p.m., the probes, named Ebb and Flow, are part the Gravity Recovery and Interior Laboratory (GRAIL) project. They will descend and impact a lunar mountain near the moon’s north pole. The crash-landing is purposeful, as the probes’ low …

Moon is Battered, Reveals New Gravity Map

A new gravity map of Earth’s moon shows a record of billions of years of impacts on its surface. The new map, generated by NASA‘s Gravity Recovery and Interior Laboratory (GRAIL) mission, is now the highest resolution gravity field map of any celestial body. It will allow scientists to learn about the internal structure of the moon, its tectonic structures, …

Huge South Pole Moon Crater Could Hold Frozen Water

The moon still holds some mysteries. One of those being whether or not there is any discernible amount of ice on the surface. While we have been to the moon, we have only visited a very small area. The way of knowing without actually going there are hit and miss too. For instance, the Japanese spacecraft Kaguya saw no discernible …

NASA GRAIL: Far Side Of The Moon

The GRAIL mission consists of two spacecraft, GRAIL-A and GRAIL-B, which have been placed into orbit around the Moon. As the two GRAILs circle the moon, changes in topography (mountains and valleys) will create fluctuations in gravitational pull resulting in slight movements to and away from each other. The change in velocity created by the movements will be measured and …
