Here's what we learned from Elon Musk's SpaceX Reddit AMA - The Verge
http://www.theverge.com/2016/10/23/13375220/elon-musk-reddit-ama-spacex-mars

Mr. Mask was held in Guadalajara, Mexico in September 2016International Space ConferenceIn the place,Presented plans to send people to Mars in interplanetary transportation system in the 2020sDid. Mr. Mask says that in addition to mankind settlements in addition to human planet Mars, Mr. Mask is aiming to make human race as a "multi planetary" race living on several planets as well as the earth.

In this AMA, many questions about this plan have been posted, and Mr. Mr. Mr. himself has received answers.

About rockets and propulsion devices
In the plan to carry mankind to Mars, SpaceX's rocket "Falcon 9" and its large version "Falcon Heavy" are used for launchInterplanetary Transport System(ITS: interplanetary transportation system) "to transport personnel and goods, etc. have been announced.

Mr. Mask asked, "When ITS can reach the sky above Mars and prepare for landing" Hovering while waiting "(floating in the air?)" Mr. Mask said, "To unexpected wind and other unforeseen circumstances As long as you do not face, you do not need to hover. " This is for the purpose of conserving fuel, and it seems that if you decide the landing point in the sky, it will land in a straight line.

Also, the ITS is designed to be able to withstand forces up to 20 G (20 times the gravitational acceleration). In normal use, it will be operated with 5 G as the upper limit, but in order to cope with various situations, it will be made to withstand the usual 2 to 3 times load.

As a problem to be addressed next to the ITS, Mr. Mr. said, "As with the main combustion chamber of a rocket engine, a new alloy with extremely high oxidation resistance that does not burn even under high pressure of high-temperature oxygen gas at 300 atm It is said to be "development of". Under such circumstances, almost all of ordinary substances will burn out, so a new alloy is indispensable for the development of high performance rocket engines. Like the following movie, rocket engine scheduled to be used in ITS "Raptor"The test has already started and it seems that the required performance is being obtained, but Mr. Mask says that there is still room for development.


Also, as with engines, improvement of corrosion resistance of fuel tank is one of the issues. It is important to develop materials and methods to withstand the harsh environments of injecting a cryogenic propellant under pressure into a tank made of carbon resin, including iron and nickel, manganese etc. Alloys madeInvar(Both amber and immutable class) to make it easier to deal with it.

Asked about the future development of the Falcon 9 rocket Mr. Mask states that the final version of the Falcon 9 series refers to the final version named "Falcon 9 Block 5". One of the major features of Falcon 9 is the "reusable" point of returning to the ground after the launch, but the Falcon 9 that reached the stage of Block 5 becomes very easy to reuse and periodic maintenance He said that it will be possible to repeat the launch almost indefinitely by doing.

◆ About Materials and Living Environment on Mars
Although Mr. Mask was asked about the refueling of fuel necessary for the activity after reaching Mars indeed, it seems that it was not in a situation where it can talk much too much at this stage. However, as a hint for that, first send an unattended "rocket for reconnaissance" to Mars, while investigating ways to landing safely,Sabatier reaction, We are going to verify the method of extracting methane and water from hydrogen and carbon dioxide. This creates water necessary for survival by using a catalyst from the carbon dioxide exhaled by humans, and it seems to be said that it is a very important technique for advancing settlement to Mars.

Regarding the environment in which humans actually live, Mr. Mask said, "In the early stage, a hemispherical dome combining triangular panels with glass set in the carbon fiber frame"Geodesic dome"On the ground. And using a lot of robots digging the ground, create tunnels and spaces in the basement, and create space for production activity pressurized to atmospheric pressure. I will use the dome on the surface as a greenhouse to live a life ".

As far as robot is concerned, Mr. Mask has established an organization "AI (artificial intelligence) development group" OpenAI "with multiple IT companies and others. As for the utilization of this technology, it is rarely mentioned in this AMA.

About flights to Mars
Mr. Mask says that he will greatly increase the number of flights to Mars in the future, and can reach Mars with the lowest energy visited once every 26 monthsHoerman transition orbitWe are planning to raise the number of rockets launched at the timing when we can use. Nonetheless, I also said that it is only when emergency supplies such as medical supplies and necessary experts are used to use this timing, and the launch will only be done once in 26 months It seems not to be.

Besides this, Mr. Mask's AMA has been asked more than 5000 questions. Of course, I do not answer all of them, but you can see a number of questions from those interested in the universe with the following threads.
