Like most kids I was mesmerised by the idea that there had once been dinosaurs living on our planet years ago and was perplexed that they had become extinct.
This, however, was eclipsed overnight by a new discovery. I was six years old when I discovered Jupiter. I didn't find it in the heavens or while looking through an astronomers telescope. I discovered Jupiter on the cover of a book in a book shop. Once I knew there were planets out there I wanted to know more.
I'm not sure where I found out what the correct order of the planets were and what there names were but I learnt this at about the same time. Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto became my mantra. I found out about the asteroid belt later, and then Kuiper's belt, and then the Oort cloud, and later even more.
I recall being very disappointed with a friend at school who was building y-wing Viper fighters from Battle Star Galactica. That's not real, that's just fiction I chastised. I'm interested in the real stuff. There are real planets and real stars out there. I did come to appreciate his fantastic model making skills and attempt to copy his fine work.

Despite the fact that Voyager & Pioneer both made close calls on Jupiter several years ago, this giant still captivates our interest. So it was with glee that I watched an Atlas 5 Rocket launch the
spacecraft Juno on a mission to Jupiter on 5 Aug 2011 (
short video here and
long version here).
Having read the objectives of the mission I am a little perplexed.
* Determine how much water is in Jupiter’s atmosphere, which helps determine which planet formation theory is correct (or if new theories are needed
*Look deep into Jupiter’s atmosphere to measure composition, temperature, cloud motions and other properties
* Map Jupiter’s magnetic and gravity fields, revealing the planet’s deep structure
* Explore and study Jupiter’s magnetosphere near the planet’s poles, especially the auroras – Jupiter’s northern and southern lights – providing new insights about how the planet’s enormous magnetic force field affects its atmosphere.
Don't we already know this? Why would we really want to know about these things in more detail? Clearly there is more to this than meets the eye - and I will have to do more research into what's happening. Are we on the brink of a new
Space Odyssey?
