Elon Musk has began to tease a talk he is set to give on Sept. 27 in which he is to reveal his plans for sending people to Mars. Musk will deliver his talk, titled “Making Humans a Multi-planetary Species,” during the International Astronautical Congress in Guadalajara, Mexico. According to the program
Elon Musk will discuss the long-term technical challenges that need to be solved to support the creation of a permanent, self-sustaining human presence on Mars. The technical presentation will focus on potential architectures for colonizing the Red Planet that industry, government and the scientific community can collaborate on in the years ahead.
Musk begins talking about SpaceX at 27:48. Hopes to go to space station in five years. Hopes to launch crew to Mars around 2025. Will describe the Mars Colonial Transporter in September at the International Astronautical Conference in Guadalajara. Mexico.
SpaceX CEO Elon Musk did an interactive Ask Me Anything Q&A last night on Reddit. Here are some excerpts from that session.
Q. Previously, you’ve stated that you estimate a 50% probability of success with the attempted landing on the automated spaceport drone ship tomorrow. Can you discuss the factors that were considered to make that estimation?
In addition, can you talk more about the grid fins that will be flying tomorrow? How do they compare to maneuvering with cold-gas thrusters?
Elon Musk: I pretty much made that up. I have no idea 🙂
The grid fins are super important for landing with precision. The aerodynamic forces are way too strong for the nitrogen thrusters. In particular, achieving pitch trim is hopeless. Our atmosphere is like molasses at Mach 4!
