Space may be the final frontier, but newer milestones keep popping up along the way. The latest: the entry of NASA's Juno spacecraft into the orbit of Jupiter. After a five-year voyage of 1.8 billion miles, the magic moment came when a series of tones arrived as confirmation of the "orbit insertion burn". Watch the celebrations (ignore the dramatic music).
Another set of sounds came through as Juno captured the 'roar' of Jupiter when the spacecraft crossed Jupiter's magnetic field.
There was a little uncertainty at first, though.
Juno carries a colour camera called JunoCam to take close-up images of the planet – and people have to help decide where to point the camera. The spacecraft also carries three Lego crew members: Galileo Galilei, Roman god Jupiter and his wife Juno.
This video reveals what the cameras on the spacecraft recorded as it closed in on its destination before the instruments were turned off for a while.
Here's Dan Riskin, Planetary Science Division Director at NASA, talking of the mission.
And finally, this breathtaking 360-degree view from NASA on the mission.
The spacecraft is supposed to circle Jupiter 37 times over the next 20 months, with the mission ending on February 20, 2018.
