The most daunting obstacle facing the human race in exploring the Solar System is the first 100 miles.
During the Apollo missions, overcoming Earth's gravity during the first three minutes of launch consumed more energy and fuel than the entire rest of the mission combined. Even today it costs over $10,000 per pound to send a payload into Low Earth Orbit. Getting into space faster, cheaper, and more efficiently is one of the main goals of most orbital tech now being researched.
