SpaceX says its BFR will fly someone around the Moon. We have questions.

Warning: Wild speculation in this story. On Thursday evening, without any advance notice, SpaceX tweeted that is had signed the worlds "first private passenger to fly around the Moon aboard our BFR launch vehicle." Moreover, the company promised to reveal "who's flying and why" on Monday, September 17. The announcement will take place at the company's headquarters in Hawthorne, Calif. There were only two other clues—tweets from Musk himself. Was the rendering of the Big Falcon Spaceship in SpaceX's tweet new? Yes, Musk said. And was he the passenger? In response to this, the founder of SpaceX simply tweeted a Japanese flag emoji. This would seem to be strong clue that the passenger is from Japan. Or maybe Musk was enjoying the epic Seven Samurai movie at that moment. By announcing this on Thursday, and waiting four days to provide more details, the company has set off a big guessing game as to who will fly. Of course that is an interesting question, but we have many other questions that we'd like to see answered before that. We've included some of those questions below, along with some wild and (slightly) informed guesses. Q. When will this flight take place? It was only last year, in February, that SpaceX announced its intention to send two private individuals around the Moon by the end of 2018 aboard a Falcon Heavy rocket and Dragon spacecraft. That date seemed unrealistic almost from the beginning, not least because the company was already struggling then to meet a 2018 deadline to fly astronauts to the International Space Station. (That will now happen no sooner than April, 2019). Musk since scrapped the lunar flyby via Falcon Heavy, saying it would be better to do such a mission via the Big Falcon Rocket (BFR) and its second stage spaceship (BFS). So it really depends when those vehicles will be ready. Q. When will the BFR and BFS be ready? That's a great question. Last September, when discussing the BFR and BFS at an international conference, Musk said SpaceX has a goal of sending two BFS launched on a BFR to Mars in 2022. At the time, Musk quipped, "Thats not a typo, although it is aspirational." The BFS is a far more complicated version than the Dragon spacecraft, which has a crew complement of at most seven astronauts for a few days in space, not dozens or more people for weeks or months. One data point we have is that SpaceX conducted its pad abort test for the Dragon crew spacecraft in May, 2015. It will take at least four years from that time to launch humans into space aboard crewed Dragon, and the Dragon spacecraft was fully funded by NASA. The company's president and chief executive officer, Gwynne Shotwell, said last week that she believes SpaceX will be hopping the BFS late next year in Brownsville, Texas. (This would seem to be a more simple exercise than a full-on pad abort test). Therefore we can probably safely assume that it will take a minimum of four years between "hops" of the BFS and actual spaceflights. That gets us from "late" 2019 to "late" 2023. As for the rocket, or BFR, we have no idea. The only real data point we have is that Musk unveiled the Falcon Heavy rocket in April 2011, and it flew seven years later. If we count 2016 as the moment when Musk unveiled the BFR, that gets us to 2023 for the rocket's readiness. So in conclusion, from these two data points, we can probably safely assume the BFR and BFS—which would easily be the most complex rocket and spacecraft ever built —will not be ready before the end of 2023. And a lot would have to go right. A lot. Q. When will SpaceX say it is flying the mission? We have two guesses. We think, from sources, that the company is targeting an internal date of 2024 or earlier. One potential date to target publicly might be December, 2022. This would be the 50th anniversary of the last human mission to the Moon, Apollo 17. This flight, carrying Gene Cernan, Ronald Evans and Harrison Schmitt, landed back on Earth on Dec. 19, 1972. Humans haven't returned to deep space since, so there is symbolic power there. Such a date would also "beat" NASA's own deep space architecture, the Space Launch System rocket and Orion spacecraft, to a human lunar orbit mission by at least a year. Q. When do you think it will happen? We have no doubt that SpaceX has the technical chops to build such a rocket and spacecraft. After all, they went from a rocket with a single engine to one with 27 engines in a little more than nine years. They're a smart bunch. But technical wizardry doesn't happen without funding. And these new vehicles will be expensive. At a minimum, development costs are probably in the neighborhood of $5 billion, and likely several multiples of that. Q. So how will SpaceX pay for it? That's the biggest question we have. We don't know. SpaceX is profitable, but even at 20 missions a year at $60 million, it probably is only meeting payroll expenses for a company of more than 7,000 people. So it is reasonable to assume that the company has been able to do a lot of the really cool developmental things it has done because it received multi-billion dollar contracts from NASA for its commercial cargo and crew programs. These helped lead to things like rockets landing on drone ships. So where does the BFR money come from? NASA isn't paying, at least for now. The US military, through its Launch Services Agreement program, may pay some development costs, but that wouldn't begin to cover the BFR or BFS. If SpaceX's satellite internet business is going to be a cash cow, that seems years away from returning big profits. So we don't know. Maybe the investor will pay $100 million for his ticket, and then convince 50 of his friends to buy a ticket too? That might be a start for funding. Q. Come on, man. Is any of this realistic? Until Musk answers the funding question, we have a hard time putting too much stock into timelines. So when we know how SpaceX is going to pay for this, then we will consider the human mission around the Moon realistic. Q. So who is going? We don't know. According to Forbes, there are 34 Japan-born billionaires in the world. It could be any of them. Or it could be a wealthy sheikh. Or it could be a rich American. We don't know. Also, it seems like there would be many people on the spacecraft, because conceptually the BFS is a big vehicle. So will the first person basically be inviting others to join him or her? We're eager to find out, but then again who is flying is not our biggest question. That's how we get from here—concept drawings of the BFR and BFS and some basic hardware—to the actual vehicles themselves. Q Anything else you can tell us? Not really. We understand that the announcement caught some SpaceX employees off guard. We've also heard that the company leaders are taking this program very seriously. All in all, it also kind of feels as though we've seen this rodeo before, with the 2017 announcement of the Falcon Heavy Moon mission. We hope for a different outcome this time.

SpaceX booked 'world's first' private passenger for a BFR Moon trip

On Monday it will announce 'whos flying and why.' We haven't seen SpaceX's BFR -- the rocket that it hopes will enable trips around the world, to the Moon, and, eventually, to Mars -- actually take flight yet, but the company says it has already booked a private passenger for a trip around the Moon. No one has been to the Moon since Apollo missions ended in the 70s, but now, in a "world's first" SpaceX is apparently taking reservations. Details like who is going and "why" are to be revealed during a livestream on Monday September 17th at 9 PM ET. Early last year Elon Musk said we'd see two humans take that trip at some point in 2018, but now we're anticipating a delay so that it can occur on the LA-built BFR, instead of a Falcon Heavy carrying a Dragon capsule. Musk has said the spaceship part of BFR could be ready for "short hopper flights" next year and test flights in three to four years. Interestingly, he also tweeted that what's shown above is a new version of the BFR, and in response to a tweet asking if he's the passenger, posted a Japanese flag emoji. SpaceX has signed the world's first private passenger to fly around the Moon aboard our BFR launch vehicle—an important step toward enabling access for everyday people who dream of traveling to space. Find out who's flying and why on Monday, September 17. Yes

SpaceX says it will send someone around the Moon on its future monster rocket

SpaceX has signed its first customer to fly on the companys huge new rocket, the BFR, the company says. The passenger will fly on the monster ship around the Moon, though there are no details yet regarding when the trip will happen. SpaceX says it will announce who is flying — and why — on Monday, September 17th. The BFR, or the Big Falcon Rocket, is the giant rocket that SpaceX is currently developing to send humans to the Moon and Mars. The BFR design, presentated by CEO Elon Musk last year, consists of a combined rocket and spaceship, called the BFS for Big Falcon Spaceship. The main rocket will have 31 main Raptor engines and be capable of sending up 150 tons to low Earth orbit, according to that presentation. In February 2017, SpaceX announced plans to send two passengers around the Moon on the companys Falcon Heavy rocket, claiming that the flight would happen at the end of 2018. SpaceX never named the passengers, and ultimately Musk admitted during the inaugural flight of the Falcon Heavy that the trip probably wasnt going to happen. Were sort of debating whether to do that on Falcon Heavy or BFR, Musk told The Verge before the launch in February of this year. It will sort of depend how well BFR development is going as to whether we focus on BFR for deep-space human flight or whether we do that on Falcon Heavy. SpaceX has signed the worlds first private passenger to fly around the Moon aboard our BFR launch vehicle—an important step toward enabling access for everyday people who dream of traveling to space. Find out whos flying and why on Monday, September 17. Its unclear if this new passenger being announced is one of the two original passengers from the Falcon Heavy flight or a new customer altogether. Musk hinted on Twitter that the customer might be from Japan. SpaceX says it will give more details on Monday, and the company has set up a livestream for the announcement. Musk gave a detailed presentation about the design for the BFR last September, during the annual International Astronautical Congress. The presentation called for a slimmed down version of the vehicle, using 31 main engines, compared to the version Musk had pitched the year before, which would have had 42. However, on Twitter this evening, Musk confirmed that the rendering of the BFR posted by SpaceX for the announcement was a new version of the vehicle. Both the BFR and BFS are reusable and designed to use their engines to lower themselves to the ground, much like how the Falcon 9s land. Musk envisions using the BFR for setting up a Moon base on the lunar surface, as well as starting a human settlement on the surface of Mars. However, Musk also noted that the BFR could be used to launch satellites, and he even proposed the idea of using the vehicle to do point-to-point travel. Conceivably, passengers on Earth could ride the rocket to distant cities, with travel times lasting just 30 minutes for destinations on the other side of the planet. Musk noted last year that his ultimate goal is to transition SpaceXs focus from the companys current line of vehicles — the Falcon 9, the Falcon Heavy, and the Dragon spacecraft — to the BFR. All our resources will turn toward building BFR, Musk said last year. And we believe we can do this with the revenue we receive from launching satellites and servicing the space station.
