Elon Musk Talks Colonizing Mars and SpaceX's Interplanetary Transport System in Reddit AMA


Serial entrepreneur Elon Musk hosted a Reddit Ask Me Anything on Saturday, answering questions about his plans for SpaceX’s push to Mars and Interplanetary Transport System.

Musk, who is also the founder and CEO of Tesla, the Boring Company, and  Neuralink, answered questions strictly related to the International Astronautical Congress. At the event, Musk discussed putting all of SpaceX’s resources into what he calls the “BFR” (Big [expletive] Rocket) and demonstrated his concept for colonizing Mars.

Mars: What to Expect

One user asked if SpaceX would perform hop tests with the BFR, build new facilities, and test propellant between now and 2022, to which the entrepreneur replied, “Yes, yes, and yes.”

Several users inquired about Musk’s plans for colonizing Mars, but his short answers didn’t provide much clarity. For instance, he was vague in his answers about adding more satellites to Mars and where the landing bases on the planet would be located. The goal, he said, is to “get you there and ensure the basic infrastructure for propellant production and survival is in place.” Musk also said that industry would “need to be built on Mars by many other companies and millions of people.”

Interplanetary Transport System

The ITS was a key focus in the AMA session. Many users asked about the design of the vehicles that will be used to travel between Earth and Mars. Musk discussed changing the design to a more cylindrical shape to get the “best mass ratio” and the function of the machine’s wings.

Lastly, when asked about the threat of radiation for astronauts, Musk wrote “ambient radiation damage is not significant for our transit times.” He followed up by adding that Buzz Aldrin, who was the second person to walk on the moon, is 87–implying that his journey didn’t have any lasting damage.
