This intense noise is mitigated by insulation and soundproofing materials within the shuttle's cabin to protect astronauts' hearing. In contrast, the vacuum of space itself is silent, as sound requires a medium like air to travel.

As the space shuttle orbits the Earth, both the shuttle and the astronauts experience free fall, resulting in a state of weightlessness. This occurs because they are both accelerating toward the Earth at the same rate due to gravity. Although gravity is still acting on them, their horizontal velocity allows them to continuously fall around the Earth rather than directly toward it. This creates the sensation of floating for the astronauts inside the shuttle.

To improve shuttle run timing, focus on enhancing your speed and agility through specific drills, such as interval sprints and lateral movements. Incorporate strength training, particularly for your legs and core, to build power and stability.
