Definition: The atmosphere of the Earth and the region of space around it.

Alright class, settle down now, let’s take a peek, At a word that’s quite important, clever and sleek! "Aerospace," you see, is more than just a name, It's a field full of wonder, a fascinating game. The dictionary’s right, it gives us the key, “The atmosphere of Earth, for all to agree!” That layer above us, where clouds softly roam, Is part of what aerospace studies call home. But wait! There’s more to this, don't you see? It stretches beyond our planet, wild and free! “And the region of space around it,” the text does say, Exploring the cosmos, far, far away! Aerospace encompasses things like rockets so bright, And satellites spinning with all their might. Spacecraft exploring, a wondrous display, Studying planets in a cosmic ballet. It’s about machines that soar and glide through the air, And ventures into space beyond compare. So remember this lesson, keep it clear and true, Aerospace is Earth's atmosphere… and space too! Do you have any questions for me now?
