“@RocketLab Congrats on many successful launches!”

“RT @cb_doge: "When I was a kid, I built model airplanes, trainsets, rockets, a radio, lots of software. Built a primitive MRI machine in co…”

“@Lukeleisher Tom is awesome. Taught me an immense amount about liquid rocket engines. And he’s just a great guy.”

“@tobyliiiiiiiiii @Erdayastronaut @NASASpaceflight Might just catch the ship with the launch tower, same as booster”

“@rustyrockets @shellenberger @mtaibbi @rumblevideo Good question”

“@lrocket It was still amazing to see it take off”

“@yasin_shafiei @thejackbeyer @NASASpaceflight @BocaChicaGal @NicAnsuini Late next month maybe, but November seems highly likely. We will have two boosters & ships ready for orbital flight by then, with full stack production at roughly one every two months.”

“Designing a rocket part w hand gestures & then 3D printing it in a metal superalloy ... http://t.co/h3KoyAb0Lt http://www.youtube.com/watch?v=xNqs_S-zEBY&feature=youtu.be”

“Aiming for Falcon rocket static fire at Cape Canaveral on the 16th and launch about three days later”

“@Erdayastronaut @RenataKonkoly @SpaceNews_Inc Am hoping to change booster design to land back on launch mount with no legs. Will require extreme precision.”

“RT @NASA: We're bringing NASA+ to @Netflix! Starting this summer, Netflix audiences will be able to stream rocket launches, spacewalks, an…”

“@SciGuySpace It’s a step in the right direction, but they should really aim for full reusability by 2026. Larger rocket would also make sense for literal economies of scale. Goal should be to minimize cost per useful ton to orbit or it will at best serve a niche market.”

“@torybruno Your company said the exact opposite in 2014 when it got a sole-source, uncompeted $11B DoD launch contract. https://t.co/Abd5sWhZDt In any event, expendable rockets are as relevant to the future as expendable aircraft. Rapidly reusable rockets are all that matter. https://www.cbsnews.com/network/news/space/home/spacenews/files/042914_ula_blockbuy.html”

“@rustyrockets What are you talking about? Nothing has changed.”

“Conducted hold-down firing of returned Falcon rocket. Data looks good overall, but engine 9 showed thrust fluctuations.”

“@DimaZeniuk Slightly different variants of stainless alloys are used in the rocket and truck, but pretty close overall”

“@flcnhvy @ErcXspace Saves mass & cost of legs & enables immediate repositioning of booster on to launch mount — ready to refly in under an hour”

“@rocketisfine @leo190102 I was simply too sexy for it https://t.co/vugJLyZVjI https://m.youtube.com/watch?v=P5mtclwloEQ”

“@DMC_Ryan New Roadster is part rocket”

“Congrats to Jeff Bezos and the BO team for achieving VTOL on their booster”

“@cb_doge They kept calling me “Internet Entrepreneur” who didn’t understand rockets, now sometimes I’m thought of as cars/rockets guy who doesn’t understand the Internet 😂”

“RT @waitbutwhy: Journalists not doing journalism anymore presents a golden opportunity for random YouTubers to skyrocket into relevance by…”

“@tobyliiiiiiiiii We will need launch tower for that. Hook height for the lift is ~140 m & both booster & ship need to be stabilized at stage separation joint.”

“RT @cb_doge: World's Most Powerful Rocket Ever Made. Flight 11 in 4 Days. https://t.co/wFzakrk43j”

“@Erdayastronaut A booster catch attempt is highly likely this year. For the ship, we need to be sure that it will survive reentry and retain aero control authority, so that means at least 2 successes landing at a precise point in the ocean.”

“Upgrades underway to enable rocket to compensate for a thrust shortfall on one of the three landing engines. Probably get there end of year.”

“Cause of hard rocket landing confirmed as due to slower than expected throttle valve response. Next attempt in 2 months.”

“@Teslarati .@NASA support for reusability with high reliability, the critical breakthrough for orbital rockets, has made a big difference”

“@PPathole @AnnieW Am in Boca working on the rocket with an awesome team, so pretty great :)”

“@DJSnM @ThePrimalDino Center core moving too fast return. Falcon Heavy is a 3 (or 2.5) stage rocket, but full & rapid reusability on Earth demand a 2 stage rocket. 1st stage returns to launch site immediately via boostback & 2nd stage orbits until ground track passes back over launch site to return.”

“@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.”

“@RenataKonkoly @Erdayastronaut First one to fly will, so Booster 4. Booster 3 will be used for ground tests. We’re changing much of design from 3 to 4. Booster 3 was very hard to build. Expect especially rapid evolution in first ~10 boosters & first ~30 ships.”

“Falcon Heavy thrust will be 5.1M lbf at liftoff -- twice any rocket currently flying. It's a beast...”

“Will post video next week of designing a rocket part with hand gestures & then immediately printing it in titanium”

“@SawyerMerritt Hydrogen is silly for cars and only barely sensible for rockets, where payload is ~1000 times more valuable”

“@Erdayastronaut @PPathole @vincent13031925 Fully reusable rockets want high T/W to minimize $/ton to orbit, because propellant cost actually matters”

“Rocket launch good, satellite in geo transfer orbit. Still so damn intense. Looking fwd to it feeling normal one day.”

“@smvllstvrs @ErcXspace Rocket motion is primarily vertical, so you want the top open”

“@Nick_Stevens_Gr Haha so true of rocket engine development”

“RT @teslaownersSV: "I'm a technologist. I build rockets and cars. I derive joy from seeing people enjoy the products that my companies make…”

“Rocket reentry will be much tougher this time around due to deep space mission. Almost 2X force and 4X heat. Plenty of hydraulic fluid tho.”

“@chamath Best rocket propulsion team ever. I love them.”

“@esherifftv @lrocket As it turns out, future versions of Raptor will ultimately exceed 700k lb-F! Honing T/W, Isp and reliability are much harder than thrust though. Rocket engines desperately want to explode.”

“Latest vertical landing rocket vid. 325M altitude, hold against wind, land w T/W>1, radar in loop http://t.co/I68Xxpb1EQ http://youtu.be/eGimzB5QM1M”

“@gurgavin The fundamental principle of ITAR law is that US companies who have advanced weapons technology, such as rockets with intercontinental range, must hire people who are permanent American residents, so that the technology does not fall into the hands of countries who wish us harm.”

“@Teslarati This isn’t quite correct. An orbital rocket needs precision that’s 3X to 4X better than a water tower, so super precise parts, fixtures & welding are needed. Suborbital is much more forgiving.”

“@rustyrockets @AndrewLawton 🤣”

“@harrison_astro We can do that partially, but detailed rocket technology is considered advanced weaponry (same tech as nuclear missiles), so there are more limitations than at Tesla”

“RT @PhysInHistory: Werner Von Braun standing next to the five F-1 engines of a Saturn V on display at the U.S. Space & Rocket Center The S…”

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