“@flcnhvy @Erdayastronaut @DiscoverMag Annoying that @ULA perpetuates myth that Delta IV Heavy or Atlas V can do some orbits that Falcon Heavy can’t. This is absolutely false. FH would have to go full expendable for GEO direct, but that’s very rare.”

“@Erdayastronaut @DiscoverMag Massive delta velocity slam from highly elliptical Earth orbit using a fully retanked, but lightened up Starship with no heat shield or fins/legs. Best choice for the impatient. Ion engines are too slow.”
“@WorldAndScience It’s possible to make a self-sustaining city on Mars by 2050, if we start in 5 years & take 10 orbital synchronizations”
“@alexwestergaard White-hot parts reached orbital entry temp of around 1650 Kelvin”
“@annerajb @Erdayastronaut @flcnhvy @austinbarnard45 We decided to skip building a new nosecone for Hopper. Don’t need it. What you see being built is the orbital Starship vehicle.”
“@Buran_Orbiter @Kristennetten @Ieoma123 😉”
“@martinengwicht @macodiseas @katlinegrey Exactly. That’s the critical point for Starship/BFR: more payload than the biggest rocket ever made, but for less money per launch than the smallest (orbital) rocket. Without something that lowers orbital flight cost by 100X, humanity will never be a multiplanet species.”
“@engineers_feed That last bit gives a good sense of what orbit is like”
“@SkiddlyBinx About 10 orbit synch windows, which are every 26 months, so self-sufficiency around 2050”
“This is for suborbital VTOL tests. Orbital version is taller, has thicker skins (won’t wrinkle) & a smoothly curving nose section.”
“About a month away from the first orbital test flight of crew Dragon”
“Amazing space progress by China. This year they did more orbital launches than the USA for the first time.”
“@ludan27 @Erdayastronaut @JeromeJaccard @Robotbeat @alan1bernard Yes, but single stage to orbit with no payload is pointless. Add Super Heavy rocket booster & orbital payload is gigantic. Only need booster on Earth, due to deep gravity well & thick atmosphere. Starship alone on moons & Mars.”
“@Erdayastronaut @annerajb Won’t land propulsively for those reasons. Ultra light heat shield & high Mach control surfaces are what we can’t test well without orbital entry. I think we have a handle on propulsive landings.”
“@annerajb Aiming for orbital flight by June”
“Falcon 9 launches Iridium to orbit from Vandenberg Air Force Base https://t.co/7GTzx0a24d https://www.instagram.com/p/Bl8M-mNAN3f/?utm_source=ig_twitter_share&igshid=18erh862v2fe1”
“@bartjehoel @djenkins6 Correct, pure electric. Wish orbital rockets could be so too, but there’s no escaping Newton’s Third Law. SpaceX is already developing high efficiency CO2 capture with H2O to form liquid CH4 (methane) & O2. Critical for propellant production at Mars Base Alpha.”
“SpaceX will try to bring rocket upper stage back from orbital velocity using a giant party balloon”
“@SpaceX Very proud of the SpaceX team! Can’t believe it’s been fifty Falcon 9 launches already. Just ten years ago, we couldn’t even reach orbit with little Falcon 1.”
“Last pic of Starman in Roadster on its journey to Mars orbit and then the Asteroid Belt https://t.co/IWSjRyTr8V https://www.instagram.com/p/Be6VZEzgAEk/”
“Third burn successful. Exceeded Mars orbit and kept going to the Asteroid Belt. https://t.co/bKhRN73WHF”
“View from SpaceX Launch Control. Apparently, there is a car in orbit around Earth. https://t.co/QljN2VnL1O”
“On Tuesday, SpaceX will attempt to refly both an orbital rocket and spacecraft for the first… https://t.co/Wm5SpjNdMb https://www.instagram.com/p/BcbQ3QVgRHr/”
“Payload will be my midnight cherry Tesla Roadster playing Space Oddity. Destination is Mars orbit. Will be in deep space for a billion years or so if it doesn’t blow up on ascent.”
“The last of ten Iridium global communication satellites delivered to orbit several hundred miles… https://t.co/TG7hNkltQd https://www.instagram.com/p/BaCFPVGgdcN/”
“Other orgs shd also develop reusable orbital rockets. If an airplane co had reusable airplanes, buying single use airplanes wd seem crazy. https://t.co/OJotlGmPHt”
“@migueldelagza They should on high velocity missions to Geostationary Transfer Orbit”
“@amirmasoudabdol Down the road, they will not even be repainted between launches. Aiming to be able to relaunch same orbital rocket booster in <24 hours.”
“@levie Tickets to orbital hotels, the moon and Mars will be a lot less than people think.”
“@arstechnica Reasons for ocean landing are technical, not economic. Orbit requires extreme horizontal velocity. Getting to space needs none.”
“As mentioned before, ship landings are needed for high velocity missions. Altitude & distance don't mean much for orbit. All about speed.”
“11 satellites deployed to target orbit and Falcon has landed back at Cape Canaveral. Headed to LZ-1. Welcome back, baby!”
“Currently looking good for a Sunday night (~8pm local) attempted orbital launch and rocket landing at Cape Canaveral”
“Jeff maybe unaware SpaceX suborbital VTOL flight began 2013. Orbital water landing 2014. Orbital land landing next. https://t.co/S6WMRnEFY5 https://m.youtube.com/watch?v=2t15vP1PyoA”
“@TobiasVdb The F9 booster can reach low orbit as a single stage if not carrying the upper stage and a heavy satellite.”
“Getting to space needs ~Mach 3, but GTO orbit requires ~Mach 30. The energy needed is the square, i.e. 9 units for space and 900 for orbit.”
“It is, however, important to clear up the difference between "space" and "orbit", as described well by https://t.co/7PD42m37fZ https://what-if.xkcd.com/58/”
“Rocket launch good, satellite in geo transfer orbit. Still so damn intense. Looking fwd to it feeling normal one day.”
“Launch window always tight when orbital synch needed. In this case, Space Station. For Earth-Sun gravity null point, moon was in the way.”
“Launch postponed to tomorrow due to high winds at the Cape, but Dragon still inbound from orbit in 90 mins”
“If u saw @TheSimpsons and wonder why @SpaceX doesn't use an electric rocket to reach orbit, it is cuz that is impossible”
“Ascent phase good. Dragon deployed to Space Station rendezvous orbit.”
“Excellent explanation of the diff betw getting to orbit vs space (suggested by @MarkusvonRoder) https://t.co/7PD42mkIEz https://what-if.xkcd.com/58/”
“Long exposure of AsiaSat 6 transiting to geo orbit over China http://t.co/mPr2Td9kkx”
“Orbit insertion and Dragon deploy all good. Falcon reentry burn also good. Waiting for landing data from tracking plane.”
“This is 1st ever orbital rocket launch w landing legs. Will attempt leg deploy & soft landing out to sea.”
“Interesting “@om:Physicist proposes a new type of computing at SXSW. Check out orbital computing http://t.co/9tawuy5dMc" http://gigaom.com/2014/03/10/physicist-proposes-a-new-type-of-computing-at-sxsw-check-out-orbital-computing/”
“Preparing to launch a Thaicom satellite to geostationary super-sync orbit at 5pm Florida time http://t.co/cEq8TEXeo6”
“Reached parking orbit. Now coasting towards equator, where the upper stage will, if all goes well, restart to raise apogee”
“@DarkSapiens Easier to make the plane change to equatorial orbit. Done in order to reduce satellite side delta V from 1800 m/s to 1500 m/s.”
