After two or three fabulous days of preparing with your crew – you're suited up and you're raring to go. The climb to 50,000 feet is marked with quiet contemplation but there's an air of confidence and eager anticipation.
Then the countdown to release, a brief moment of quiet before a wave of unimaginable but controlled power surges through the craft. You are instantly pinned back into your seat, overwhelmed but enthralled by the howl of the rocket motor and the eye- watering acceleration which, as you watch the read-out, has you traveling in a matter of seconds, at almost 2500mph, over 3 times the speed of sound.
As you hurtle through the edges of the atmosphere, the large windows show the cobalt blue sky turning to mauve and indigo and finally to black. You're on a high; this is really happening, you're loving it and you're coping well. You start to relax; but in an instant your senses are back on full alert, the world contained in your spaceship has completely transformed.
