The joke is that one of the NASA engineers, [[Megan]], reveals that they actually intended for Juno to arrive at {{w|Saturn}}, but actually arrived at Jupiter with a timing that was still apparently the same within one second. Given the reaction from the spokesperson, she knew this but it was not supposed to slip out. | The joke is that one of the NASA engineers, [[Megan]], reveals that they actually intended for Juno to arrive at {{w|Saturn}}, but actually arrived at Jupiter with a timing that was still apparently the same within one second.

| − | This is, of course, not true, because if Saturn had been the intended target, Juno would have been off course by 10.25 AU (1 AU is the distance from the Earth to the Sun, or 149597870700 meters) when it arrived at Jupiter.

A similar measurement coincidence was noted in [[what if?]] ''{{what if|4|A Mole of Moles}}''. Also, Saturn is a [http://www.space.com/18477-how-far-away-is-saturn.html maximum of 1.7 billion '''kilometers'''] (1.1 billion miles) away from the Earth. For Jupiter, [http://www.space.com/18383-how-far-away-is-jupiter.html this distance] is 968 million km (601 million miles) away. But when traveling between planets, long detours are necessary to reach the goal with a velocity that enables the space craft to go into orbit. So it is just a coincidence that Juno has traveled a distance to get to Jupiter in kilometers that fits with a possible distance to Saturn in miles. The mixup of units mentioned above was directly referenced in [[1643: Degrees]]. |

In the book solely written by {{w|Arthur C. Clarke}} they go to Saturn. In the film (from 1968), however, they found it impossible to make Saturn's rings well enough to satisfy director (and co-writer) {{w|Stanley Kubrick}} so in the film version, they ended up at Jupiter instead. (Arthur C. Clarke later made the film canonical when he wrote the sequel ''{{w|2010 (film)|2010}}'', where the plot would only work with Jupiter, mainly because of its size and partly due to its {{w|Galilean moons|four big moons}} especially {{w|Europa (moon)|Europa}}). | The mix-up of Jupiter and Saturn could be a reference to the {{w|2001: A Space Odyssey (novel)|book}} and the {{w|2001: A Space Odyssey (film)|film}} ''2001: A Space Odyssey'' that were written simultaneously.
