Hey there!
When Columbia re-entered the Earth, the hot gases in the atmosphere (atmospheric gases), they destroyed the wings and it ultimately was destroyed. That technically means that the spacecraft wasn't shielded correctly, and led to a tragedy as well as major rethinking and reform for NASA.

The Mexican War and settling the Oregon question meant that the United States now stretched from the Atlantic to the Pacific. Western expansion soon took a major leap forward with the California Gold Rush, as thousands from the eastern states, as well as from foreign nations, headed for the territories of California and Nevada, hoping to strike it rich.
