A rocket takes four days to fly from the Earth to the moon. Someone who drives a car an average of 15,000 kilometers annually would take over 25 years to cover the same distance.
It’s a journey of 384,400 kilometers.
The Part-Time Scientists have been preparing for their mission to the moon for eight years. Eight years of meticulous planning and calculations to land a rover safely on the moon to conduct research. But even when the goal is nearly within reach, as the landing module carrying the two rovers races toward the moon at over 6,000 kilometers per hour – an airliner normally travels at around 800 kilometers per hour – there is still so much that can go wrong.
Will the retrorockets deliver exactly as much thrust as they were designed to? Will the trajectory not deviate even a centimeter from its precisely calculated ellipses?
Bottom line: the challenge of completing all the phases of a mission to the moon successfully is roughly comparable to balancing a tray full of glasses of water in your hands as you run barefoot over hot coals—without spilling even a drop.
It can only be done by pressing boldly forward and keeping a cool head.
„Hundreds of thousands of kilometers are waiting to be crossed, full of harsh darkness, the intense radiation of the sun and extreme temperature changes.”
