In case you missed it, SpaceX's Elon Musk's talk titled 'Making Humans a Multiplanetary Species' is below (linked from YouTube). This is an entertaining video, packed with interesting data, lasting an hour:
Here are some random notes, in no particular order:
- 01:13: Talk starts
- Musk is a nerd, and comes off as awkward while speaking. Do not pay attention to the style, listen to him.
- There are some really interesting scientific/engineering data on some of the slides. They are very very cool!
- 8:25: Estimate of an average one-way ticket cost to Mars
- 11:04: Southwest advertisement around
- You gotta love this guy; he mentioned a few times that going to Mars at scale will be a bit 'tricky'.
- 12:10: Discussion on refueling.
- 14:25: Propellant discussion
- 16:55: Simulation of the overall system (a.k.a, movie with extremely high cheese quotient) starts. Make sure you pay attention to the numbers shown.
- Cheesy video? Yes, but you need to listen to what he is going to say around 21:35.
- 23:00: Don't skip slide shown; very interesting re-use numbers on that page.
- 24:36: Size discussion. His comment on size at 23:45 is priceless.
- And, the comment at 27:03.
- 29:24: Nice comparison of past and current space vehicles on the slide. Pay attention to the last two on the right, and the 'white bars.'
- Engine numbers at 32:30 mark; rocket booster intro at 33:45.
- There will be 42 engines, folks! Interesting choice of number :)
- 36:42: Raptor engine configuration at the base of booster
- 37:22: Spaceship intro starts.
- 37:43: Musk says that "liquid oxygen tank on the spaceship is probably the hardest piece of the whole vehicle, and [...] they started work on that piece."
- Cool ship capacity chart at 39:42.
- 40:10: "Mars transit times as little as 30 days in the distant future."
- 40:36: Heat shield technology info starts
- 41:15: Fly-thru of the crew compartment. (Smaller version of 'Ascension' ship; needs music.) He claims that the environment on the ship will be really fun. If it is going to be anything like the first Tesla cars, it probably will be.
- 42:47: Details of the propellant plant on Mars.
- 43:22: More details about reuse. New cost number is $140K per ton.
- 44:15: Founding sources!
- 46:35: Timelines (of SpaceX). Don't miss the pictures.
- 48:34: One of the most exciting engineering timeline in the history of human civilization. This is one fast startup!
- 53:09: "Most of our missions (60%) are commeircial geo missions."
- 53:37: Timeline for Mars launches. First development ship in 4 years. Also, potential FedEx killer (54:30 :)
- 56:30: Trying to send Dragon 2 to Mars in a couple of years; another mission in 2020.
- 58:45: Raptor engine vs Merlin; same size, 3 times operating pressure.
- Producing 300 engines per year!
- 59:00: Raptor firing test video
- 1:00:30: Carbon fiber tank, requirements, production issues and picture (at 1:01:31)
- More cool pictures at 1:02:17 and 1:02:24
- 1:02:44: Beyond Mars! No, no, he is serious! Lotsa cool pictures; he has a plan...
