PhaseExperience
AscentIntense kinetic energy and acceleration
Apogee (peak altitude)Brief period of weightlessness
DescentIncrease in gravity effects and vertical velocity

Our journey begins with the craft’s velocity increasing rapidly to climb to the edge of space. During ascent, we’re propelled by significant kinetic energy, resulting in a steep climb. The speed necessary for this phase is a balance of potential energy and the craft’s propulsion capabilities.

Once we reach the peak of our path, known as apogee, we linger in a state of microgravity. Here we experience the exhilaration of weightlessness, which only enhances as we momentarily become free from Earth’s grasp. During this stage, our speed stabilises, and we savour a few minutes where the laws of physics allow us a glimpse into the life of an astronaut.

Our descent is marked by the return of gravity’s pull, gradually increasing as we fall back to Earth. The transition from negligible gravity back to normal conditions is as dramatic as the initial ascent, providing us with a holistic perspective of kinetic and potential energy at play.
