“Of Earth and Mars”

“@NASASpaceflight Unlike its aircraft division, which is fine, the FAA space division has a fundamentally broken regulatory structure. Their rules are meant for a handful of expendable launches per year from a few government facilities. Under those rules, humanity will never get to Mars.”

“@Erdayastronaut Detanking & inspections now. Good progress towards our “Hop in & go to Mars!” goal.”

“@arstechnica @SciGuySpace We’re just trying to get people to Mars. Help would be appreciated.”

“@engineers_feed Indirectly, an electric rocket is possible by using electricity to convert CO2+H2O —> CH4+O2. This will be needed on Mars even for early missions & Earth too over time.”

“@ID_AA_Carmack I hope so. Wings don’t work on the moon at all and def not well on Mars. Also, no runways.”

“@Erdayastronaut @flcnhvy @ErcXspace Production is hard, prototypes are easy. Building ~1000 Starships to create a self-sustaining city on Mars is our mission.”

“Thank you, South Texas for your support! This is the gateway to Mars.”

“Mars, here we come!!”

“@peterrhague It’s designed to make life multiplanetary, otherwise extreme overkill for mere Earth sector activity! Starship fleet mass to orbit per year will be more than 1000 times all current Earth rockets combined, including Falcon. Necessary, for a city on Mars.”

“@Erdayastronaut @rweb11742 Merlin is a strong local maximum design, but kerosene is suboptimal fuel, no matter what you do. What matters is cost per ton to Mars. CH4 is the only choice imo. Important: O2/CH4 allows OF ratio of ~3.5 vs ~2.5 for kerosene, so ~78% of propellant is oxygen.”

“@ICannot_Enough @ZainRaz4 @vincent13031925 @JonErlichman Yes, although I didn’t expect the stock to rise so much so soon. The reason for the stock options is that they’re needed to help pay for humanity to get to Mars in 10 to 20 years.”

“@bamtheteslaman1 @cleantechnica Doesn’t seem to be any life in this solar system. Maybe under the ice of Europa or extremophile bacteria below the surface of Mars. Worth reading: https://t.co/ym0d53HgyS https://en.m.wikipedia.org/wiki/Drake_equation”

“@flcnhvy Good grief! SpaceX is getting zero money for this. Starship is designed to carry people & cargo around Earth (also to moon & Mars). Vast majority of use will be civilian. It’s just like an airline in space. All airlines sometimes carry military cargo, but ~99% is civilian.”

“@johnkrausphotos @Patreon @SuperclusterHQ @SpaceX Maybe this should be the flag of Mars”

“@PPathole @Erdayastronaut @NASASpaceflight @BocaChicaGal @TheFavoritist Probably 5 or 6 with an optimized tanker, although filling up the ship in orbit isn’t required for Mars, so 4 is possible”

“@PPathole @Erdayastronaut @dauqhx @universal_sci Mars is easier than the moon for propellant production. Could get going with only one ship, where the ship itself is the propellant plant. Needs to make ~2 tons/day.”

“@dauqhx @universal_sci There’s a lot of frozen CO2 & H2O on Mars. Heating the planet will densify the atmosphere. It’s solvable.”

“@universal_sci Perhaps one day there will be an ocean on the northern part of Mars”

“@RGVaerialphotos @SpaceX @Erdayastronaut This little spit of dirt will take us to Mars”

“@austinbarnard45 Mars is looking real”

“Impressive Tianwen-1 Mars rover mission launched by China today https://t.co/FsyA3I0HrU https://www.space.com/amp/china-tianwen-1-mars-mission-launch.html?__twitter_impression=true”

“@PPathole We should bring Life to Mars”

“@nnalinas @BBCScienceNews Trying to set a good example haha. Mars needs people!”

“@OprahSide Maybe he should design flag of Mars”

“@nicebit_net @valleyhack If you get past Mars, the asteroids, moons of Jupiter & Saturn, inevitably you reach Uranus!”

“Mars is my souldog”

“Gateway to Mars”

“@PPathole That’s when all life on Earth will be boiled off. What matters is how long civilization is capable of making the jump to Mars. This could be a very short period of time measured in decades. It took 4.5 billion years to get to this point & civilization isn’t looking super stable.”

“@JonErlichman 5 years ago. We need to accelerate progress towards fully reusable rockets. Cost per ton to orbit needs to improve by >1000% from where Falcon is today for there to be a self-sustaining city on Mars.”

“@Erdayastronaut @NASA @SpaceX Mars needs to happen soon”

“@raytech247 @flcnhvy @Erdayastronaut @ValkyrieBaron11 @NASASpaceflight Yes, mostly because you can use the ship every week going to the moon instead of every two years for Mars (best case)”

“@flcnhvy @Erdayastronaut @ValkyrieBaron11 @NASASpaceflight Would be about 10 times that cost for payload to surface of Mars”

“@PPathole @Erdayastronaut @farrier_nyker @GeetPurohit3 @YoavOffek Looks about right. Ice mining/refining on Mars & maximizing total system efficiency will be hard. CO2 is easy, as Mars atmosphere is mostly that. Also has good amount of N2, which is important for life.”

“@Erdayastronaut @farrier_nyker @GeetPurohit3 @YoavOffek Yes, converts CO2 & H2O to CH4 & O2. Perfect for Mars! https://t.co/WF9AGgee12 https://en.m.wikipedia.org/wiki/Sabatier_reaction”

“@Erdayastronaut @SciGuySpace What’s troubling is that this doesn’t get humanity a base on the moon or even a small crewed Mars mission”

“@RationalEtienne @Alfzeta There will be no Mars if we let them take our freedom away”

“@kulpability Don’t need the cash. Devoting myself to Mars and Earth. Possession just weigh you down.”

“@archillect Red sky of Mars is Blue at dawn & dusk”

“@teslaownersSV @Erdayastronaut Fully reusable orbital rocket, then orbital refilling, then Mars”

“@Erdayastronaut @PPathole @austinbarnard45 @LabPadre Exactly. No point in an abort system on Mars, so got to make the core ship super safe.”

“@NuovaRealta @cleantechnica Will call when we reach Mars”

“@SamTalksTesla @JaneidyEve Mars is god of war & memes are a form of war … and fun too! Neither will be destroyed. Ceres, moons of Jupiter & Saturn prob come next.”

“Mars is to Earth, as Terminus was to Trantor”

“Going max hardcore on design/production Starship here in Boca. It’s awesome! Feels a bit like a Mars simulator.”

“@John_Gardi Not needed, but will be very useful on Mars due to light speed latency”

“@Erdayastronaut @Blamblas @latimes @SpaceX @blueorigin Exactly. Mars propellant production will combine atmospheric CO2 & water (ice) to make CH4 (methane) & O2. Will do same on Earth long-term. Short-term, each Falcon flight uses roughly same fuel mass as a 747 flight. Falcon is ~71% oxygen & Starship is ~78%, so mostly not fuel.”

“@SciGuySpace We should have a base on the moon, a city on Mars”

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

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