Look out Monday - Ebb and Flow Nowhere to Go

Two space probes known as Ebb and Flow, respectively, are due to crash onto the dark side of the moon. Why? Because NASA don't want thesethings to just fall anywhere - most especially to randomly kerplunk where astronaut Neil Armstrong trod. As before in the history of western man the motto is ‘Let’s send our debris to the dark side.’

Background is the two spacecraft were launched in September of 2011 - they entered the lunar orbit earlier this year. Correlating data from the two objects, researchers were able to measure variations in the moon's gravitational field.  Understanding the gravity helps to discern the composition of the moon and in turn it cosmological history. But our probes are running out of fuel. Look out, Dale here comes Ebb and Flow.
