America's space program has come a long way since the country's founding in 1776. In fact, human flight was still seven years away when the Declaration of Independence was signed. However, it wasn't long before the United States began to make its mark in the skies.
What Happened
In 1783, the Montgolfier brothers' hot-air balloon carried two men on a 25-minute flight over Paris, marking the beginning of human flight. Over the next century, the United States continued to push the boundaries of aviation, with the Wright brothers' successful flight in 1903.
The Space Age
The United States' space program began in earnest in the 1950s, with the launch of the first American satellite, Explorer 1, in 1958. Since then, the country has led the way in space exploration, with notable achievements including the first moon landing in 1969 and the construction of the International Space Station.
What Did the Night Sky Look Like in 1776?
If you stepped outside on July 4, 1776, the sky would have looked much as it does today, with the same stars and constellations visible. However, careful measurements would have shown that the stars were not in quite the same positions they occupy today.
