Any adjustment of velocity—whether to dock with another module, avoid space debris, or return to Earth—requires a burn of the engines. Launch and Re-Entry: The Extreme Phases The most intense g-forces in space missions occur during the launch and re-entry phases.

This pressure is not a mysterious force but a direct consequence of inertia, and it represents the most tangible encounter most people will have with g-forces in space. The Physics of Acceleration and Inertia To understand g-forces in space , one must first look at the ground.
During a typical launch to Low Earth Orbit, the rocket must overcome Earth's gravity and atmospheric drag while simultaneously accelerating to orbital velocity of roughly 28,000 kilometers per hour. Managing Forces During Maneuvers Even within the microgravity of orbit, g-forces play a critical role.

The "g" in g-force stands for standard gravity, the acceleration due to Earth's pull at sea level, measured as 9. In space, while microgravity exists, the physics remain identical; a spacecraft firing its engines creates the exact same inertial force on its crew, regardless of the surrounding environment.
More About G-forces in space
Looking at G-forces in space from another angle can help expand the discussion and give readers a second clear paragraph under the same section.
More perspective on G-forces in space can make the topic easier to follow by connecting earlier points with a few simple takeaways.
