@jm_marchante @kekai What should we change?

@kekai Munro’s analysis of Tesla engineering is accurate, both pro & con. I think he will appreciate some elements of the Model Y body design.

@Erdayastronaut @SPEXcast @SciGuySpace Even more important for a a reusable rocket, as cost of propellant actually becomes relevant & anything below T/W of 1 is wasted fuel & oxygen

Hehehe https://t.co/bnlN7Vn6bl

@jameslin123321 @Erdayastronaut Helping to pay for this is why I’m accumulating assets on Earth.

@jameslin123321 @Erdayastronaut Loading the Mars fleet into Earth orbit, then 1000 ships depart over ~30 days every 26 months. Battlestar Galactica …

@mstrwilliam00 @Erdayastronaut Aiming for 20 to 30 years, like aircraft

@Kristennetten @PicklePunchD @Erdayastronaut Yes. There will be a lot of jobs on Mars!

@PicklePunchD @Erdayastronaut Needs to be such that anyone can go if they want, with loans available for those who don’t have money

@EcoHeliGuy @Erdayastronaut Yeah. A lot of work is needed for propellant production on Mars.

@PRANSHUAGARWA13 @Erdayastronaut Yes

@Erdayastronaut That’s the goal

@Erdayastronaut Building 100 Starships/year gets to 1000 in 10 years or 100 megatons/year or maybe around 100k people per Earth-Mars orbital sync

@Erdayastronaut Starship design goal is 3 flights/day avg rate, so ~1000 flights/year at >100 tons/flight, so every 10 ships yield 1 megaton per year to orbit

Megatons per year to orbit are needed for life to become multiplanetary

@fighteer1 @LCS_Big_Mike @SciGuySpace That’s about right

@g33st111 Reaction to Cyberpunk 2077 slipping release date to September

@SPEXcast @SciGuySpace What’s amazing is how non-linear the effect of gravity is. Starship can travel by itself from surface of Mars to surface of Earth, but requires massive booster on Earth with orbital refilling to get to Mars, which is ~38% of Earth gravity.

@SPEXcast @SciGuySpace Densification isn’t needed to return the ship & limited cargo from Mars, but it’s an option for increasing cargo return capability if needed

@SciGuySpace Fundamental issue with SLS is that it’s not reusable, which means that a billion dollar rocket is blown up every launch! 💯 tragedy.
