GRAIL Launch to Moon Nears



NASA's Gravity Recovery and Interior Laboratory mission is less than two weeks away from launch as scientists and engineers discuss how its two spacecraft will reveal new data about the surface and interior of the moon, from crust to core. GRAIL is set to launch from Cape Canaveral Air Force Station the morning of Sept. 8.

NASA Moon Mission in Final Preparations for September Launch

NASA's Gravity Recovery And Interior Laboratory (GRAIL) mission to study the moon is in final launch preparations for a scheduled Sept. 8 launch from Cape Canaveral Air Force Station in Florida.
GRAIL's twin spacecraft are tasked for a nine-month mission to explore Earth's nearest neighbour in unprecedented detail. They will determine the structure of the lunar interior from crust to core and advance our understanding of the thermal evolution of the moon.

NASA Sets GRAIL/DELTA II Launch Coverage Events

NASA's GRAIL spacecraft is set to launch to the moon aboard a United Launch Alliance Delta II rocket on Sept. 8, 2011, from Cape Canaveral Air Force Station, Fla. There are two instantaneous (one-second) launch windows at 12:37:06 and 13:16:12 GMT (8:37:06 a.m. and 9:16:12 a.m. EDT). The launch period extends through Oct. 19. The launch times occur approximately 4 minutes earlier each day.

NASA Hosts News Conference on Upcoming Moon Mission

NASA will host a news conference at 11 a.m. EDT (8 a.m. PDT), on Thursday Aug. 25, to discuss the upcoming launch of the Gravity Recovery And Interior Laboratory (GRAIL) mission. Scheduled to launch Sept. 8, GRAIL will help answer longstanding questions about Earth's moon and provide a better understanding of how Earth and other rocky planets in our solar system formed.

NASA's GRAIL Moon Twins are Joined to Their Booster
 
NASA's lunar-bound GRAIL twins were mated to their Delta II launch vehicle at the Cape Canaveral Air Force Station's Launch Complex 17 at 8:45 a.m. EDT (5:45 a.m. PDT) today. The 25-kilometre trip from Astrotech Space Operations in Titusville, Fla., is the last move for GRAIL before it begins its journey to the moon. NASA's dynamic duo will orbit the moon to determine the structure of the lunar interior from crust to core and to advance understanding of the thermal evolution of the moon.

GRAIL Launch Less Than One Month Away

GRAIL-A and GRAIL-B - completed their final inspections and were weighed one final time at the Astrotech Space Operations facility in Titusville, Fla., on Tuesday. The two Gravity Recovery and Interior Laboratory (GRAIL) spacecraft will orbit the moon in formation to determine the structure of the lunar interior from crust to core and to advance understanding of the thermal evolution of the moon. GRAIL's launch period opens Sept. 8, 2011, and extends through Oct. 19. For a Sept. 8 liftoff, the launch window opens at 5:37 a.m. PDT (8:37 a.m. EDT) and remains open through 6:16 a.m. PDT (9:16 a.m. EDT).
Later this week, the two spacecraft will be loaded side-by-side on a special adapter and packaged inside a payload fairing that will protect them during their launch into space. Next week, GRAIL is expected to make the trip from Astrotech to Launch Complex 17 at the Cape Canaveral Air Force Station where it will be mated with its United Launch Alliance Delta II Heavy rocket.

NASA Announces Launch Tweetup for Grail Moon Mission

NASA will host a two-day launch Tweetup for 150 of its Twitter followers on Sept. 7-8 at the agency's Kennedy Space Centre in Florida. The Tweetup is expected to culminate in the launch of the twin lunar-bound GRAIL spacecraft aboard a Delta II rocket from Cape Canaveral Air Force Station in Florida.
The launch window opens at 5:37 a.m. PDT (8:37 a.m. EDT) on Sept. 8. The two GRAIL spacecraft will fly in tandem orbits around the moon for several months to measure its gravity field, from its crust to core, in unprecedented detail. The mission also will answer longstanding questions about the moon and provide scientists with a better understanding of how Earth and other rocky planets in the solar system formed.

NASA's Twin Craft Arrive in Florida for Moon Mission

NASA's twin lunar probes have arrived in Florida to begin final preparations for a launch in late summer. The two Gravity Recovery And Interior Laboratory spacecraft (Grail) were shipped from Lockheed Martin Space Systems, Denver, to the Astrotech payload processing facility in Titusville, Fla., Friday, May 20. NASA's dynamic duo will orbit the moon to determine the structure of the lunar interior from crust to core and to advance understanding of the thermal evolution of the moon.

NASA's Two Lunar-Bound Spacecraft, Vacuum-Packed

NASA's two Gravity Recovery And Interior Laboratory (Grail) spacecraft have completed all assembly and testing prior to shipment to Florida.
As seen in the photo, taken April 29, technicians installed lifting brackets prior to hoisting the 200-kilogram Grail-A spacecraft out of a vacuum chamber at Lockheed Martin Space Systems, Denver. Along with its twin Grail-B, the Grail-A spacecraft underwent an 11-day-long test that simulated many of the flight activities they will perform during the mission, all while being exposed to the vacuum and extreme hot and cold that simulate space.

Lockheed Martin finishing work on moon-mapping GRAIL spacecraft

Twin spacecraft are undergoing final tests at Lockheed Martin's Waterton Canyon facility for an extremely precise mission that will map the moon from crust to core.
Scheduled for shipment May 20 to Cape Canaveral, Fla., the nearly identical probes will work together to measure tiny variations in the moon's gravitational field.
