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 [...]

NASA Spacecraft Returns First Video From Far Side Of The Moon

The twin GRAIL spacecraft will map the moon's gravity field in unprecedented detail, resulting in the most accurate gravity map of the moon ever made. The mission also will answer longstanding questions about Earth's moon, including the size of a possible inner core, and it should provide scientists with a better understanding of how Earth and other rocky planets in the solar system formed.
