SpaceX Announces New Lunar Mission Michael Weinhoffer Senior Reporter At an evening event on September 17, SpaceX made a big announcement about their even bigger rocket: Japanese billionaire Yusaku Maezawa will be flying to the Moon onboard SpaceX’s BFR rocket in 2023 along with six to eight other passengers. These passengers will be the first private passengers on a deep space mission and will be flying on the most powerful rocket ever built. Besides announcing the lunar mission, which was originally supposed to launch on the Falcon Heavy, Elon Musk gave his yearly update on the design of the BFR and its development progress. The BFR (Big Falcon Rocket) was publicly introduced in 2016, but the engines for the rocket have been in development for several years. The BFR is capable of sending 150 tons to Low Earth Orbit, and with orbital refueling with tankers, can send 150 tons of cargo to Mars. Thirty-one Raptor engines on the first stage will produce 13.9 million pounds of thrust at liftoff, which means that the BFR will surpass the Soviet N-1 rocket as the most powerful rocket ever flown. The second stage of the vehicle is the spaceship, which will be powered by seven Raptor engines and seat approximately one-hundred passengers. The first BFR is being built under a giant white tent in the Port of Los Angeles, which will become its permanent manufacturing location. The BFR is designed to replace all of SpaceX’s current vehicles and could be used for manned solar system exploration, ISS resupply missions, satellites launches, and even suborbital transport to cities around the world. At the SpaceX event, Mr. Musk provided an update on both Raptor engine development and the design of the spaceship. The most noticeable update is the addition of three landing fins on the rear of the spaceship. In addition, the second stage will host seven Raptor engines that are identical to the first stage engines, in order to

reduce the development cost of the system, which Musk estimated is about $5 billion. He also displayed a physics simulation of the BFR reentering into an atmosphere, whether it be Earth or Mars. The BFR will be nearly vertical as it descends through the atmosphere so that the entire body of the spaceship can act as a heat shield instead of just the front portion. The BFR will right itself and land vertically on Earth and Mars, which is a feat SpaceX has pulled off many times with the Falcon 9, and this year with the Falcon Heavy. Musk also provided an estimated timeline for the test flights of the rocket, but it is highly dependent on manufacturing and testing progress. Initial “hops” of the spaceship are planned for next year, followed by more intense suborbital flights in 2020. After the BFR has flown several times unmanned around the Earth and possibly around the Moon, Mr. Maezawa and his guests will climb onboard in 2023 for their lunar journey. Forty-two-year-old Yusaku Maezawa is a fashion designer, art collector, and billionaire who has always been fascinated by the Moon. Maezawa said at the SpaceX event that “I did not want to have such a fantastic experience by myself. I choose to go to the moon with artists. I choose to invite artists from around the world on my journey.” To do this, he established the #DearMoon website, which can be reached at https://dearmoon. earth/. He plans to take several artists (including painters, musicians, sculptors, and architects) from around the world to the Moon, and after they land back on Earth they will create a piece inspired by the journey that will be shown to the world. Maezawa hopes this project will inspire people from around the world about the impact of both art and space exploration. He did not disclose the price he paid for a seat on the BFR, but Musk said it was a substantial amount that made an impact on the funding of the BFR, which is all done by SpaceX.
