While the planet’s atmosphere gradually thins, a specific altitude marks where official spaceflight begins. This requires overcoming gravitational pull and atmospheric drag, particularly within the lower 50 kilometers where air density remains significant.
Thermosphere Transition to Interplanetary Space and the Onset of Official Spaceflight
Instead, vehicles must achieve orbital velocity to generate the necessary centrifugal force to remain aloft. Understanding this transition helps clarify the environment where spacecraft operate and humans experience weightlessness.
Atmospheric Layers and Gradual Transition Earth’s atmosphere does not end abruptly at 100 km but consists of several distinct layers. The energy required for this journey defines the capabilities of modern launch systems.

The stark contrast between the blue-white curve of Earth and the blackness of space defines the visual threshold. This environment enables scientific experiments and observations impossible under terrestrial conditions.
