Looking forward to Nasa's arrival at Jupiter
Sky at Night presenter Dr Chris Lintott explains why he's looking forward to the Juno mission's arrival at Jupiter.
The Nasa spacecraft will aim to discover how the planet formed as well as whether the planet has a solid core.
It should be captured by the gas giant's gravity early on Tuesday (GMT) to go into orbit.
There will be updates on Juno's orbit insertion across BBC News, and the BBC Sky At Night programme will run a special programme dedicated to the mission on Sunday 10 July at 20:30 BST, on BBC Four.
