“Dragon flies over the SpaceX #GrasshopperProject at our central Texas test site. It will jump soon. http://t.co/P17Z56II”

“The London Sunday Times created a chart showing how Falcon compares to the Saturn V and Shuttle http://t.co/nJMPtYPd”

“@ssBlueStockings @ninoles @medickinson @thephysicsgirl It’s cool for kids & if used in a fun way, but if you called yourself a “rocket scientist” in aerospace, they would think you’re 🙃”

“And, yes, I do in fact know that this sounds crazy. That is not lost on me. Nor I do think SpaceX will do this alone.”

“@ClovenLife No, but shielding got fragged every flight. More control authority is for Falcon Heavy, but also enables Falcon 9 to land in heavier winds.”

“@FBeuster There will be a combined booster static fire. Maybe a few.”

“Simulations show launch ok with bad valve. Still, better to stop & fix. Recalling rockets after launch is not an option.”

“Would also like to thank @USAirForce for allowing us to use their long range comm system for Dragon in free drift.”

“SpaceX will go public at some point, as I think it should ultimately be owned primarily by the public "@bm_ will SpaceX go public?"”

“Woohoo, rocket hold down firing completed and all looks good!!”

“@JimDeKort @SpaceX It does”

“@andyzalk sounds like the right name for the rocket booster”

“Will show Johnny Cash hover slam rocket video for the first time in about 15 mins. Test footage only 36 hrs old. #SXSW”

“@kpe @SpaceX @grierallen @natedapore Cool, thanks for letting us know. This is helpful for figuring out fairing reusability.”

“@BArtusio Three cable elevator on a crane. Wind force on Mars is low, so don't need to worry about being blown around.”

“Falcon 9 and Dragon now vertical on the launch pad, surrounded by 300 ft tall lightning towers http://t.co/iERgA2RP”

“Thrusters will also fire during reentry to adjust touchdown point. Next version will land w helicopter precision #Dragon”

“Am pushing launch back approx a week to do more testing on Dragon docking code. New date pending coordination with @NASA.”

“@CMaggiore50 Typing Mars after holding down the T symbol on the center console works on S and X. Also try renaming your car 42.”

“@jclishman @bearsper @rSpaceX yes”

“@TobiasVdb The F9 booster can reach low orbit as a single stage if not carrying the upper stage and a heavy satellite.”

“@drew @SpaceX Not from us, but it's awesome”

“Congratulations to @OrbitalSciences! “@CNETNews: Orbital's Antares rocket makes successful test flight http://t.co/y7bwdDMGCi” http://cnet.co/17QCmKa”

“Navigation bay pointing to deep space and star map being generated by star tracker one. Yes! #DragonLaunch”

“Dragon deorbit burn was good. All thrusters operating. On target for splashdown.”

“The SpaceX theme song by Total Ghost is just too good ... ooh ooh ooh http://t.co/BuKuopI5 http://www.youtube.com/watch?v=MezkEiS-6jA”

“Was misquoted by BBC as saying "Europe's rocket has no chance". Just said the [Franco-German] Ariane 5 has no chance, so go with Ariane 6.”

“T minus 60 seconds. Terminal autosequence initiated. #DragonLaunch”

“@SmileSimplify @beboutside @Hyperloop @SpaceX @paradigm_hype @swissloop The latter. There are pretty long gaps between each team run, so livestream is not the way to go.”

“@zerosixbravo @john_gilleran True, but that's a minor factor for rockets”

“@JimDeKort @SpaceX Rotates 180 degrees and does a retro burn”

“Recovery ship just heard the sonic booms from Dragon reentry and has data transmission lock.”

“@rocketrepreneur Meant to say 200 AR for production vac engine. Dev will be up to 150. Beyond that, too much flow separation in Earth atmos.”

“@BenCam137 @FifthRocket Exactly”

“T minus 10 minutes ... Entering terminal count #dragonlaunch”

“Just test-fired the Superdraco rocket engine. Enables launch escape and landing on thrusters. SpaceX.com http://t.co/IJaYVEE9”

“Almost done reviewing Dragon code with @NASA. Looks good so far. Target launch date is May 19, right after Soyuz docks.”

“@AuerSusan @valleyhack True. Also, Ariane primary bay can deliver slightly heavier satellites than Falcon 9. Falcon Heavy is needed ...”

“Just completed the rocket rollout review at SpaceX HQ in California. Almost time to launch. Pucker factor increasing...”

“Computer glitch found by @SpaceX avionics while bench testing on IM. Couldn't replicate on vehicle. Launch proceeding...”

“@TheHackersNews @SpaceX Thanks”

“Interview in Nature describing why we should extend life to Mars http://t.co/6Ux0q4OX http://www.nature.com/news/backing-up-the-biosphere-1.10395”

“Making large scale rocket propulsion landing work well is a critical step towards a fully reusable Mars transport system”

“View from landing leg camera on Falcon rocket test rig (aka Grasshopper Project) http://t.co/xhFe87AM http://yfrog.us/09qmmivexdorhtchxitvhjzsz”

“@williamwinters @rocketrepreneur pretty close”

“@ID_AA_Carmack That works for Dragon, but hard to do for something long like Falcon”

“Um, while awesome in its own way, that was not actually the SpaceX theme song. It seems that irony is sometimes lost in a tweet.”

“@QuantumG When we launch I want to know that SpaceX has done everything possible to keep the astronauts safe. Only a few more years to go.”

“Next month is also when our Dragon spaceship docks with the Space Station for the first time. Major pucker factor...”

“@MarinaSBlinova Rocket boost stage reaching 0 m/s in one piece :) Will know soon. Odds not high.”
