The space craft that visited Pluto recently flew past Pluto and into open space beyond because it had no brakes, its ability to observe Pluto only lasted a few hours.

There is no mention of a braking system, that a craft going even faster, even the speed of a speeding bullet, will need brakes. Air brakes wont work in a vacuum.

There is no air. Can the engine be reversed? What guiding system is there? Are there little engines that can manouvre it?, that respond to a steering wheel.

How long will it take to speed up and slow down?, a miscalculation on a trip to the moon may result in the craft going past the moon faster than Cambridge leaving Carlisle United behind.

Can you get Star Radio on the radio?
