The US space agency (Nasa) has succeeded in placing two new satellites in orbit around the Moon.
Both spacecraft were put in elliptical paths around the lunar body over the weekend after performing braking manoeuvres following their more than 100-day journey from Earth.
The identical Grail twins are to map gravity variations across the lunar body in unprecedented detail.
This will help scientists refine our theories for how the Moon formed.
It will also enable them to test new ideas, such as the provocative suggestion made earlier this year that there were probably two moons in the sky above Earth billions of years ago.
Lead scientist Dr Maria Zuber is certainly hoping for some dramatic discoveries.

That was a good write-up by Jonathan Amos. Conveyed what science is and can be. A child presented with a Lionel train set. The possibilities, limited they may be, are wondrous.
