Incredible pictures reveal the battered surface of Saturn's icy moon Rhea in satellite's last ever close-up trip


Nasa say the pictures will be the last close-up images taken of Rhea 

  • Detailed photos show crater-ridden surface of Saturn's second largest moon
  • Pictures taken by Cassini spacecraft, which flew within 997km of Rhea

These stunning images reveal the battered surface of one of Saturn's icy moons in extraordinary detail.
The pictures were taken by Nasa’s Cassini spacecraft during its final flyby of Rhea, which is about 1.2billion km from Earth.
The unprocessed images show its large craters formed by millions of years of collisions with space rocks.

Nasa's Cassini spacecraft took the photographs on March 9 as it flew within 997km (620 miles) of the surface of the moon - one of Saturn's 60 satellites.
It was Cassini's fourth and final encounter with Rhea. 


 
The spacecraft is due to pass the moon in a few years’ time but at a much greater distance. 
It is only scheduled to operate until 2017 and will not make another flyby of the moon before it disintegrates. 
Carolyn Porco, Cassini imaging team lead from the Space Science Institute in Boulder, Colorado, was quoted by NBC as saying: 'Take a good, long, luxurious look at these sights from another world, as they will be the last close-ups you'll ever see of this particular moon'.
The flyby was designed to measure Rhea's gravity field.

Scientists also collected cosmic dust to try to work out the rate at which objects and small meteors bombard the Saturn system.
However, the spacecraft managed to take detailed pictures of the moon's surface revealing its craggy and ancient landscape.
New 'curious' features were shown for the first time, which scientists still do not understand.
These include a narrow fracture or 'graben' along the surface, which is made up of a block of ground lower than its surroundings and bordered by cliffs on either side.

A Nasa statement said: 'This feature looks remarkably recent, cutting most of the craters it crosses, with only a few small craters superimposed.'
Rhea is Saturn's second largest moon and has a diameter of 1,500km (949 miles).
The Cassini mission is jointly run by NASA, the European Space Agency and the Italian Space Agency.
Rhea was discovered by mathematician and astronomer Giovanni Domenico Cassini, who gave his name to the mission.
