The Experience of Suborbital Flight

Embarking on a suborbital flight is to undertake a journey unlike any other. As we reach the designated altitude for suborbital travel, the craft enters a suborbital trajectory, allowing us the unique experience of weightlessness. This sensation, often described as microgravity, occurs because the vehicle is in freefall; the forces of gravity are still at play, but they don’t pull us down in the same way they do on Earth.

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.

Our understanding of these physics principles not only boosts our appreciation for the mechanics behind suborbital flights but enriches the wonder of the entire experience. For more insights into this incredible adventure and the mechanics of such flights, visit
