“@WholeMarsBlog Computers are absurdly more accurate than humans. How long would it take for a human to render even one frame of a modern video game at low res? The computer will do high res at 120 frames per second. Not a contest.”

“@SecDuffy The safety of air travel is a non-partisan matter. SpaceX engineers will help make air travel safer.”

“@wholemars @WR4NYGov Logs show driver disengaged Autopilot four seconds before crashing”

“Top SpaceX priority is and will remain supporting @NASA crewed spaceflight and National Security missions”

“@DoctorJack16 Main Tesla subjects will be scaling to extreme size, which is needed to shift humanity away from fossil fuels, and AI. But I will also Include sections about SpaceX, Tesla and The Boring Company.”

“@Erdayastronaut @SpaceX @Caspar_Stanley @IzanRamos2002 Most importantly, we need to delete or thermally protect remaining secondary structure, so we can remove shrouds”

“@Erdayastronaut We are breaking ground soon on a second Raptor factory at SpaceX Texas test site. This will focus on volume production of Raptor 2, while California factory will make Raptor Vacuum & new, experimental designs.”

“@cleantechnica 2.1 sec 0-60 mph is base model before adding rocket thruster option”

“@jonastsla @jamesdouma @heydave7 @karpathy @WholeMarsBlog Our video clips are usually shorter than 30 seconds, but the overall point made by James is accurate. Tesla is probably labeling more images per week than any other project ever done and our rate of labeling is increasing rapidly.”

“@TylerG1998 @NASASpaceflight @SpaceX It is! Looks like we can get 378 sec Isp with this version of Raptor Vacuum, so over 380 sec with some improvements down the road.”

“@Erdayastronaut @SpaceX I super support public spaces around our production & launch sites, wherever it can be done safely and securely. When covid passes, we will open up our restaurant to the public & figure out ways to allow limited access to the High Bar.”

“@WholeMarsBlog Next release (10.12) is another step towards all NN’s using surround video & reconciling output to a unified vector space for control code. Improves complex intersections in heavy traffic. Many upgrades to core code, so taking longer to debug issues. Probably Wed/Thurs release.”

“@Erdayastronaut @Teslaconomics @SpaceX We could build a lot more, but the next version of Raptor is really the one to scale up production. We begin testing it in McGregor within a week or so. Regenerative cooling and secondary flow paths have been made integral to the whole engine, thus no heat shield is required.…”

“@SirineAti @mn_google We will have a second Starship stack ready to fly in August and then monthly thereafter”

“@imPenny2x @SecDuffyNASA They won’t. SpaceX is moving like lightning compared to the rest of the space industry. Moreover, Starship will end up doing the whole Moon mission. Mark my words.”

“@WholeMarsBlog Then HW5, which has been renamed to AI5, in the second half of next year. The Tesla AI5 computer has ~10X the capability of HW4 computer and Tesla makes the whole software stack.”

“@teslaownersSV First, no one has ever mentioned rehab to me ever. Second, if they are saying that I was able to lead Tesla to be by far the most valuable carmaker and SpaceX to be by far the most valuable space company *simultaneously*, that is the greatest compliment I have ever received!”

“@WholeMarsBlog @StuartZuckerma1 ~4.5X increase in params should be ready for wide release later this year. Super frugal use of memory bandwidth, caching exactly what is needed & squeezing microseconds out of everything are needed to maintain the frame rate. And the whole system needs to be retrained.”

“@WholeMarsBlog Car should also reverse slightly if it peeks into an intersection & sees fast-moving cross-traffic (just like a person would)”

“@WholeMarsBlog The new Plaid S is our best car ever. Will be first production car to achieve 0-60mph in under 2 secs & it has four doors & seats up to 7 people.”

“RT @SpaceX: The second successful catch of the Super Heavy booster https://t.co/FanOyDoE8Z”

“@Erdayastronaut @Caspar_Stanley No, bottom static aero pushes engine section back, counteracting Starship’s low center of mass on reentry caused by the engine section. Aiming for 60 to 70 deg angle of attack during high heating portion of flight. Don’t want to reenter with engines blasted by plasma.”

“@PPathole @nextspaceflight @NASASpaceflight @BocaChicaGal @SpaceX Actually, so-called “secondary” structure is the hard part – so many pipes & wires. Tall stuff & small stuff are the toughest things about Starship.”

“@WholeMarsBlog Designing in the cameras, liquid-cooled Tesla computer (always go liquid-cooled!) and high security internet gateway will probably take major car companies about three years. Might as well start now! We want to be helpful, as we were with making our patents available for free,…”

“@yousuck2020 @SpaceX That’s the first BFR airframe/tank barrel section made of a new carbon fiber material”

“The AEI meeting wasn't secret and I was only there for a few hours to talk about Mars and sustainable energy. Nothing to do with Trump.”

“RT @interesting_aIl: SpaceX successfully caught a rocket booster mid-air for the second time in history https://t.co/MnYlrprbB4”

“@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.”

“@GadSaad I know several people who got myocarditis. I almost had to go to the hospital after my second booster shot, which was mandatory in order to travel.”

“@WholeMarsBlog Sensors are a bitstream and cameras have several orders of magnitude more bits/sec than radar (or lidar). Radar must meaningfully increase signal/noise of bitstream to be worth complexity of integrating it. As vision processing gets better, it just leaves radar far behind.”

“Air Force certifies @SpaceX to compete for launching national security satellites http://t.co/tLYcEDJFPV http://www.af.mil/News/ArticleDisplay/tabid/223/Article/589724/air-forces-space-and-missile-systems-center-certifies-spacex-for-national-secur.aspx”

“RT @SpaceX: Fram2 is also the second mission to fly with Dragon’s cupola. At nearly 4’ wide, the cupola is the largest continuous window in…”

“@WholeMarsBlog There is a lot of merit to having your own chip design. We optimize its usage down to the microsecond.”

“@Adamklotz_ @AaronS5_ @crheller @SpaceX More ground stations & less foolish packet routing will make the biggest differences. Looking at speed of light as ~300km per millisecond & satellite altitude of ~550km, average photon round-trip time is only ~10ms, so a lot of silly things have to happen to drive ping >20ms.”

“Dragon abort test stats: 0 to 100 mph in 1.2 sec, top speed of 345 mph”

“@MarcusHouse A second is a long time to a rocket. Said another way, it was 1000ms or ~50 control cycles away from hitting the tower. Not actually that close.”

“@AngryPackOMeese @dlxinorbit @doug_ellison @dsfpspacefl1ght Maybe that plan works out, but I will seriously eat my hat with a side of mustard if that rocket flies a national security spacecraft before 2023”

“Particularly trying to understand the quieter bang sound a few seconds before the fireball goes off. May come from rocket or something else.”

“@Adamklotz_ @Erdayastronaut @josh_bickett @ajtourville @SpaceX Will still use hot gas maneuvering (RCS) thrusters, as ~5X more efficient than nitrogen (300 sec vs 60 sec Isp)”

“@flcnhvy SpaceX has 8000 employees in California, Washington, Texas & Florida. Operating this entire time, as we have national security exemption. Zero deaths or serious illnesses.”

“@JeffTutorials @WholeMarsBlog That’s arguably a security issue, but allowing companies to use other payment options, especially for in-app purchases would be fair. As soon as they allowed that, they would have to lower their fees. As for the cost of reviewing apps for security, a fixed fee makes sense.”

“@ByeonChansoo @WholeMarsBlog @garyblack00 @28delayslater @SawyerMerritt @WR4NYGov @RealDanODowd You had me there for a second 😂”

“@flcnhvy @alvianchoiri We’re not seeing notable differences yet. I think the boosters could probably do 100+ reflights. Some of the (small) composite helium tanks would need to be replaced. Maybe turbopump hot sections.”
