Nasa has lost a rover in a Mars megastorm

Opportunity, the longest-running Mars rover, is currently in a tricky situation.

It's caught in the middle of a mega dust storm on the red planet.

The storm is so fierce that dust particles block out the Sun.

Nasa has lost contact with the rover and can't check to see if it's OK.

So will it come out in one piece?
