We can all learn something from the European Space Agency. They had a vision for where they wanted to go, they figured out what they needed to do to get there and then they did it.
Their goal was to land a probe on a comet to learn more about the origins of the solar system. They achieved their goal last week, scoring a first for humanity and making a lot of scientists splutter with excitement.
Landing on a comet is not a zippy exercise like in Armageddon where you just slingshot Bruce Willis around the moon. Nor is it like The Empire Strikes Back where you zoom across the galaxy for a few minutes before reversing on to an asteroid.
The ESA scientists had to plan ahead for a 10-year journey through the solar system, culminating in a complex set of manoeuvres that required their spaceship and its little probe to approach, orbit and land on a comet that was moving at 135,000km/h.
This is a project that was given formal approval in 1993. Could we have envisaged landing on a comet in 1993? In 1993, I had no clue what I would be doing in 2014, let alone how to plan it into reality.
