A rocket built for traveling throughout our solar system could revolutionize travel on Earth, according to Elon Musk. Using a "BFR" flying at a max speed of 18,000 mph, he says we could fly anywhere on Earth in under an hour. Musk revealed the plan during his speech at the 68th International Astronautical Congress 2017 in Adelaide, Australia, where he also showed SpaceX's plans for lunar and Mars missions. The BFR (yes, it stands for what you think it stands for) is SpaceX's next rocket after the Falcon Heavy that Musk said the company hopes will launch by the end of this year. Unlike all of its previous rockets, this one will be fully reusable, and capable of refueling in space, which is key for his plans to do things like resupply the ISS, land on the moon, and start sending missions to Mars by 2022. With refueling in space, the BFR can make trips to the Moon's surface without needing any fuel production there, enabling the creation of "Moon Base Alpha."
