“@SciGuySpace His plan makes no sense. Just a worse version of Apollo. Starship will enable a permanently occupied moon base and even a city on the moon one day.”

“@Erdayastronaut @SpaceX All correct. Parachutes were originally the backup landing system, with SuperDraco thrusters as primary. Difficulty of proving thruster landing safety *and* architecture being suboptimal for moon/Mars caused us to change focus to parachutes.”

“@Erdayastronaut Making a fully reusable orbital rocket of any design is one of the hardest engineering problems of all time. Much, much harder than going to the Moon, which is why it still hasn’t been solved. I am cautiously optimistic that Starship will achieve full reusability next year.”

“RT @cb_doge: One took us to the Moon. The other will take us to Mars and beyond. https://t.co/r4iJ3eXrMh”

“@BryceSpaceTech Still basically nothing compared to the orbital mass flux needed for a base on moon or Mars”

“@DavidWillisSLS @_Jevis_ @PPathole Needs legs for moon & Mars”

“@esherifftv @SciGuySpace Starship will enable a permanently occupied moon base”

“@ajtourville @SpaceX The new launch pad is already designed for the 10,000 tons of thrust version, which is almost exactly 3 times more powerful than the Saturn V Moon rocket”

“@DJSnM But the Moon Station that Starship will enable will be great”

“@peterrhague No, we’re going straight to Mars. The Moon is a distraction. Mass to orbit is the key metric, thereafter mass to Mars surface. The former needs to be in the megaton to orbit per year range to build a self-sustaining colony on Mars.”

“@SciGuySpace I think we can do it. Progress is accelerating. Starship offers a path to far greater payload to the Moon than is currently anticipated in the Artemis program. A permanently crewed Moon base is possible.”

“RT @XFreeze: SpaceX will have the first Moon base and it's much closer than most realize Starship can carry the highest tonnage to space o…”

“RT @SpaceX: SpaceX shares the same goal as NASA of returning to the Moon with a permanent presence as expeditiously and safely as possible.…”

“@Astro_Elliott @LifeboatHQ Once you have rapidly reusable rockets of sufficient size to carry >100 tons of payload, it is not clear that cost per ton to orbit/moon/Mars improves with a larger rocket. Aircraft, for example, have moved away from 747/A380 to 777, which has ~100 tons of payload.”

“@Erdayastronaut @dauqhx @universal_sci Starship propellant is ~78% oxygen, so an O2 plant on the moon would be enough. Otherwise, we could brute-force it with tankers to low Earth orbit. That’s probably faster.”

“@Tenjin37151 @Space_Station @SpaceX @Commercial_Crew @NASA @esa @JAXA_en @astro_kimbrough @Astro_Megan @Thom_astro @Aki_Hoshide As described in The Moon is a Harsh Mistress (great book), a linear accelerator would be great for the moon. Earth’s gravity is too high & atmosphere too dense for accelerators to be a good solution vs reusable boosters imo.”

“@levie Tickets to orbital hotels, the moon and Mars will be a lot less than people think.”

“@DJSnM The ISS requires a lot of care and feeding. Time to say goodbye and move on to the Moon and Mars.”

“@Rothmus Over time, SpaceX will enable anyone to go to space and travel to the moon and Mars”

“@SenBillNelson @SpaceX Thank you! We look forward to supporting @NASA in returning American astronauts to the moon.”

“@_rykllan @SpaceX @FelixSchlang @MarcusHouse @Erdayastronaut @bluemoondance74 @NextHorizonsSF Rocket fleets grows”

“@AdrianDittmann Mars (and the moon)”

“@george_sowers Orbital refilling is essential to get serious tonnage to Mars and Moon”

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

“RT @tetsuoai: SpaceX just officially shifted its #1 priority to building a self-growing city on the Moon. Not a base. Not an outpost. A cit…”

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

“@_Shameless_Plug @Falcon9Block5 @bluemoondance74 @arstechnica @SciGuySpace .@BoredElonMusk”

“@ESYudkowsky Our meat computers are feeble (sigh). We did get manage to get a few monkeys to the moon using rockets designed with slide rules, which is pretty impressive.”

“RT @SecDuffyNASA: Another major step toward landing Americans on the Moon’s south pole. The progress @SpaceX demonstrated with today's St…”

“@sleepingromi @yousuck2020 @rogerwaters @SpaceX @dearmoonproject Yes”

“@Everman SpaceX will prob build 30 to 40 rocket cores for ~300 missions over 5 years. Then BFR takes over & Falcon retires. Goal of BFR is to enable anyone to move to moon, Mars & eventually outer planets.”

“@SciGuySpace Starship can also be used to create a large, permanently crewed Moon Base Alpha research station”

“@13ericralph31 @SPEXcast @bluemoondance74 @Orion_Sword @Some1gee @Erdayastronaut @SpaceX After the GoT finale, we dropped it to 6”

“@Alejandro_DebH @macshlibber @SpaceflightNow Advancing humanity’s understanding of the Universe is a fundamental motivator for SpaceX! Starship can put giant 🔭 in orbit & on moon. With an occluder, could image 🌏 in other star systems.”

“@Erdayastronaut @keego73 Absolutely. You’ve touched on a very important point. The ship must be easy to repair on the moon and Mars.”

“Honored that @NASA would entrust @SpaceX with the Apollo 11 (first moon landing) launch pad http://t.co/LmqxRwsKFW http://www.nasa.gov/press/2014/april/nasa-signs-agreement-with-spacex-for-use-of-historic-launch-pad/#.U1BNuPldVqw”

“@Erdayastronaut @rmarcilhoo @kimitalvitie @SpaceXNow @ChrisG_NSF @NASASpaceflight Exactly. We’re on the wrong planet for SSTO. No problem on Mars or any of the moons.”

“RT @NASAAdmin: Returning to the Moon will prepare us for the grand journey to Mars. If we get this right, we’ll see the Stars and Stripes o…”

“@PhysInHistory Major breakthrough. They used logarithms and slide rules to design the Saturn V moon rocket.”

“RT @cb_doge: Real photos of Mars and the Moon. https://t.co/FWhahBm9JA”

“@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.”

“@AstrumMining @SPEXcast @McMurchie @Robotbeat @John_Gardi @SpaceX Moon first, Mars as soon as the planets align”

“RT @teslaownersSV: “Starship is capable of building a city on Mars and a city on the moon. That's what it's designed to do. But we're being…”

“@gork @Crypto_Moon369 @Starlink 💞”

“@bluemoondance74 @SptlightVids @SpaceX Working on Tesla global logistics”

“@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)”

“@sivanithu @tobyliiiiiiiiii @cabral_psyd @Erdayastronaut @imatsb @thesheetztweetz @SciGuySpace @Some1gee @RocketLab Some of the small launcher activity is cool, especially @rocketlab. Downsides are helicopter retrieval doesn’t scale to bigger rockets & is highly weather-dependent. Also, propulsive landing is needed for moon/Mars. That said, it’s probably right move for small LEO vehicle.”
