 * __What is an Intercontinental Ballistic Missile?__**
 * These missiles were developed to carry nuclear arms without planes.
 * Each missile could carry more than one warhead.
 * There are three phases to a launch: Boost, Midcourse, and Reentry.
 * The first phase takes 3 to 5 minutes and it is the very beginning of the launch.
 * The second phase takes around 25 minutes, depending on where the strike is. This is where the ICBM is in sub-orbital spaceflight.
 * The last phase only takes 2 minutes. The warheads travel at a speed of 4 km/s to hit their target.


 * __Who created the first ICBM?__**
 * The first ICBM was developed by Nazi German scientists working under Wenher von Braun.
 * Braun's team was trying to make this so they could bomb an American city like New York during World War II.
 * Later and more modern designs were created by a Russian named Sergey Korolyov.
 * The advancements that Sergey made led to launching Sputnik into space.


 * __When was the first successful testing of the ICBM?__**
 * After Sergey made advancements on the ICBM, it helped the Soviet Union launch the first successful satellite, Sputnik, into space.
 * Only two years after the Soviet Union launched the first successful ICBM, the United States followed up with their own version.
 * The U.S. launched the Atlas D on July 29,1959.
 * No more successful launches by other countries happened until the early 2000s.
