Question: Choose how you want this story to end.

By Becky Evans PUBLISHED: 13:05 EST, 17 March 2013 | UPDATED: 06:22 EST, 18 March 2013 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. Scroll down for video Battered: Saturn's icy moon Rhea has been pictured in extraordinary detail Craggy: The deep craters were formed by collisions with space rocks Deep space: Cassini took the images as it flew with 620 miles of the surface of the moon

Saturn: The flyby was designed to enable scientists to measure

OPTIONS:
- Becky Evans's gravity field
- Cassini's gravity field
- Cassini spacecraft's gravity field
- Craggy's gravity field
- Earth's gravity field
- Nasa's gravity field
- Rhea's gravity field
- Saturn's gravity field
- icy moon Rhea's gravity field


Answer: Imagine you are watching a fun and exciting space adventure. Now, how should it end? The choices here are about who or what's gravity field scientists were measuring (A gravity field is like a big invisible force that pulls everything towards the center of a planet or moon. It's why when we jump, we come back down to the Earth). 

Let's decide on the ending! Do we want our brave spaceship Cassini to measure the gravity of:

- Becky Evans's gravity field: This doesn't sound right. Becky Evans is the author of this story, not a planet or moon!
- Cassini's gravity field: This also doesn't sound correct. Cassini is the spaceship itself. It's like trying to measure your own height using your own hands!
- Cassini spacecraft's gravity field: Again, this seems a bit off because we're talking about the spacecraft again.
- Craggy's gravity field: This one is also not quite right. Craggy describes the surface of the moon, not an actual place.
- Earth's gravity field: If the story was about measuring Earth's gravity field, our spaceship wouldn't have needed to fly all the way to Saturn's moon, right? It can do that job from here.
- Nasa's gravity field: This one's funny! NASA is an organization full of brainy scientists who investigate space. They don't have a gravity field of their own!
- Rhea's gravity field: This seems likely. Rhea is the moon that our spaceship Cassini was exploring.
- Saturn's gravity field: This could be a good analysis too, but since our spaceship was getting close to Rhea, it might be more interested in what's happening there.
- icy moon Rhea's gravity field: Well, Rhea is an icy moon, so this answer is just a fancy way of saying "Rhea's gravity field"! 

So based on all of this, the best endings would be that Cassini was studying "Rhea's gravity field" or the "icy moon Rhea's gravity field". This means the scientists wanted to understand more about how strong Rhea's gravity is, and that's a very important thing to know if we want to land other spaceships there in the future!
