Oceanus Procellarum, or Ocean of Storms, an expansive flat basaltic basin that covers approximately 17 percent of the Moon’s near side, is surrounded by a series of linear gravitational anomalies (shown in red), as revealed by NASA’s GRAIL spacecraft. These anomalies indicate that the large basin was formed by volcanic processes rather than […]

NASA’s GRAIL spacecraft after acoustics testing at Lockheed Martin Space Systems Company near Denver. Image Credit: NASA/JPL-Caltech Even though the twin spacecraft Ebb and Flow, part of the Gravity Recovery and Interior Laboratory mission, crashed into the Moon’s surface December 17, 2012, scientists continue to pour over the massive amounts of […] In this image, both of the impact sites of the mirror-image GRAIL spacecraft can be seen. The final resting spots of these two spacecraft were imaged by the Lunar Reconnaissance Orbiter. Image Credit: NASA/GSFC/Arizona State University NASA’s Lunar Reconnaissance Orbiter (LRO) has found the impacts made by its cousin(s), the Gravity Recovery and […] NASA has selected the United Launch Alliance Delta II to send its ICESat-2 spacecraft into polar orbit. Photo Credit: Alan Walters / awaltersphoto.com CAPE CANAVERAL, Fla — The Launch Services Program at NASA’s Kennedy Space Center, located in Florida, has selected United Launch Alliance’s (ULA) Delta II rocket to launch the agency’s Ice, […] A poster made for the GRAIL mission. Image Credit: JPL After launching aboard a Delta II rocket from Cape Canaveral Air Force Station on September 10, 2011, at 9:08 a.m., and orbiting the Moon for almost a year, the two GRAIL spacecraft, which came to be named Ebb and Flow, have ended their […]
The GRAIL expedition to explore and map the Moon’s gravity field is scheduled to end today with the intentional impact of twin spacecraft, Ebb and Flolw, into the lunar surface. NASA TV plans to begin live coverage of the mission’s end at 5:00 p.m. ET The spacecraft are scheduled to impact the surface […] An artist’s concept of the twin GRAIL spacecraft, Ebb and Flow, in action around the Moon. Image Credit: NASA/JPL-Caltech/MIT NASA’s GRAIL mission to map the gravity field of the Moon has enjoyed success beyond any expectations, but all good things must come to an end. […] 
This image depicting the porosity of the lunar highland crust was derived using bulk density data from NASA’s GRAIL mission and independent grain density measurements from NASA’s Apollo moon mission samples, as well as orbital remote-sensing data. Image credit: SA/JPL-Caltech/ IPGP For well over a year now, two washer-machine sized twin […] In this image, the mirror-image GRAIL spacecraft are readied for launch at the Astrotech facilities in Titusville, Florida. Photo Credit: Jason Rhian The GRAIL spacecraft, Ebb and Flow, have begun their extended mission, and are now mapping the gravity field of the Moon and at half the altitude they were during the main […] In this image a Delta II rocket thunders off of Cape Canaveral Air Force Station’s Space Launch Complex-17 in Florida. At the time this was thought to be the final flight of a Delta II. With this latest announcement however the Delta II will see at least three more missions – all from […] |
