“A Million Humans Could Live on Mars By the 2060s https://t.co/d0nlk1xfOl via @NatGeo http://on.natgeo.com/2cTNcqn”

“Good article on the interplanetary transport system on Gizmodo https://t.co/nysjRDQWFz https://news.google.com/news/ampviewer?caurl=http%3A%2F%2Fgizmodo.com%2Fthis-is-how-elon-musk-plans-to-build-a-city-on-mars-up-1787146547%2Famp#pt0-433220”

“12m rocket booster diameter, 17m spaceship diameter, 122 m stack height”

“@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.”

“@williamwinters @rocketrepreneur pretty close”

“@rocketrepreneur 382s is with a 150 area ratio vacuum (or Mars ambient pressure) nozzle. Will go over specs for both versions on Tues.”

“SpaceX propulsion just achieved first firing of the Raptor interplanetary transport engine https://t.co/vRleyJvBkx”

“@thescalex @SpaceX @IAC2016 @YouTube its it is”

“Preview of the @SpaceX interplanetary transport system at @IAC2016 https://t.co/Rz4XmeAoRw https://m.youtube.com/watch?v=7TYJyCCO8Dc”

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

“Turns out MCT can go well beyond Mars, so will need a new name…”

“Thoughtful Op-ed in Space News much appreciated https://t.co/CJq5g3NIEK http://spacenews.com/op-ed-despite-spacex-setback-future-of-private-space-exploration-is-bright/”

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

“Support & advice from @NASA, @FAA, @AFPAA & others much appreciated. Please email any recordings of the event to report@spacex.com.”

“Still working on the Falcon fireball investigation. Turning out to be the most difficult and complex failure we have ever had in 14 years.”

“@scrappydog yes. This seems instant from a human perspective, but it really a fast fire, not an explosion. Dragon would have been fine.”

“Loss of Falcon vehicle today during propellant fill operation. Originated around upper stage oxygen tank. Cause still unknown. More soon.”

“Thanks for the longstanding faith in SpaceX. We very much look forward to doing this milestone flight with you. https://t.co/U2UFez0OhY https://x.com/ses_satellites/status/770602110996082688”

“View of Dragon from @Space_Station cupola https://t.co/1HjljLWdFi”

“Really tempting to redesign upper stage for return too (Falcon Heavy has enough power), but prob best to stay focused on the Mars rocket”

“Can't wait to see all three cores of Falcon Heavy come back for landings! First two will be almost simultaneous. https://t.co/ryMiewZM4L http://www.orlandosentinel.com/news/space/go-for-launch/os-spacex-landing-pads-space-coast-20160718-story.html”

“Falcon on LZ-1 at Cape Canaveral https://t.co/dBkjBCDIRs”

“Have to focus on tonight's @SpaceX launch. Will post Tesla (master) product plan afterwards.”

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

“Ascent phase & satellites look good, but booster rocket had a RUD on droneship”

“Fourth rocket arrives in the hangar. Aiming for first reflight in Sept/Oct. https://t.co/TqW8d6Cc3U”

“Yay, baby made it home! https://t.co/KYyUX9zNYD http://www.universetoday.com/129240/falcon-9-arriving-droneship/”

“Fast replay of today's rocket landing on SpaceX droneship OCISLY https://t.co/I0QQ2D3BtE https://youtu.be/4jEz03Z8azc”

“@dfjsteve Very similar. The crush core in the Falcon legs is reusable after soft landings, but needs to be replaced after hard.”

“Crush core is aluminum honeycomb for energy absorption in the telescoping actuator. Easy to replace (if Falcon makes it back to port).”

“Rocket landing speed was close to design max & used up contingency crush core, hence back & forth motion. Prob ok, but some risk of tipping.”

“3 mins to launch https://t.co/i5jNDs9MCO https://x.com/spacex/status/736305431417491457”

“@SpaceX There was a tiny glitch in the motion of an upper stage engine actuator. Probably not a flight risk, but still worth investigating.”

“@SchaFFFFFF Flight 24 is def capable of flying again, but it makes sense to apply ground delta qual to rocket w toughest entry conditions.”

“Great image of ancient Mars https://t.co/iy3AngxKlq https://x.com/discovermag/status/733361619133026304”

“@joshuapinter @juliusvolz Full height of Falcon 9 boost stage on legs is ~165 ft”

“Falcon Heavy side boosters can use most of the same airframe as Falcon 9, but center core needs to be buffed up a lot for transfer loads.”

“Most recent rocket took max damage, due to v high entry velocity. Will be our life leader for ground tests to confirm others are good.”

“May need to increase size of rocket storage hangar”

“Woohoo!! https://t.co/0P8n8VmFbr https://x.com/spacex/status/728457165606780928”

“Rocket reentry is a lot faster and hotter than last time, so odds of making it are maybe even, but we should learn a lot either way”

“@JohanMancus Historical precedent. Mars vehicle will be metric.”

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

“@elonmusk Max performance numbers are for expendable launches. Subtract 30% to 40% for reusable booster payload.”

“Just posted latest max payload capabilities of Falcon 9 and Heavy https://t.co/Z45Y5V7G91 http://www.spacex.com/about/capabilities”

“Dragon 2 is designed to be able to land anywhere in the solar system. Red Dragon Mars mission is the first test flight.”

“@dannysparker Aiming for relaunch in 3 to 4 months, pending detailed examination and 10X refiring of a returned booster”

“Great video history of Falcon 9 by Kinematic https://t.co/EeGPVW7kq2 https://m.youtube.com/watch?feature=youtu.be&v=tU1b1H2EWU4”

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

“@TheHackersNews @SpaceX Thanks”
