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 mission with [...]

GRAIL Mission Ends

 

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 [...]

NASA Breathes New Life Into Reliable United Launch Alliance Workhorse

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 Vandenberg [...]

A Step Closer to the Lunar Holy GRAIL
