For one thing, Crew Dragon will have a touchscreen for the astronauts to operate instead of a lever, something Behnken and Hurley, who were military test pilots before becoming astronauts, were not accustomed to. Falcon 9/Dragon compared to Soyuz/Progress: Alan Erskine: 12/3/10 8:46 AM: The Progress has the same Launch Escape System as the Soyuz, minus the solid motor and does so for aerodynamic reasons. Unlike the space shuttle, which resembled a plane, Crew Dragon is ateardrop-shaped capsule.Much like the Mercury, Gemini and Apollo capsules during the 1960s and '70s, or the Soyuz … Re: Falcon 9/Dragon compared to Soyuz… I'm pretty sure a 70's Molniya-M has little to do with a 2010's Soyuz-2. Or a pass for landing them in the ocean?Acronyms, initialisms, abbreviations, contractions, and other phrases which expand to something larger, that I've seen in this thread:New comments cannot be posted and votes cannot be castWelcome to r/SpaceXLounge, sister subreddit to r/SpaceX. Why doesn't the Falcon 9/Dragon have the same LES without crew? "This spacecraft, Crew Dragon, is SpaceX's design, start to finish and make no mistake of that," Behnken said.Demonstration Mission 2, or Demo-2, as this mission is dubbed, will also be the first time astronauts fly a commercial space vehicle.Instead of relying on NASA to own, operate and maintain its own spacecraft, the space agency will instead buy seats on capsules built by private companies. "I'm counting on SpaceX to accelerate the time in the next 20 years," he said. NASA currently pays $86 million per seat to fly astronauts to the ISSUnlike the Soyuz capsule that only takes approximately six hours to head to the ISS when it lifts off the pad at Baikonur Cosmodrome Kazahkstan, Crew Dragon's trip to the space station will last about19 hours from the time it lifts off Kennedy Space Center.This is due to orbital mechanics, explained Benji Reed, SpaceX director of crew mission management. This statistic does not include secondary mission failures. Falcon 9 had 1 secondary mission failure (CRS-1) Soyuz-2 had 3 secondary or partial mission failures, and Soyuz-FG had 0 such failures.
So I wouldn't say it's statistically more reliable.Real world examples help me learn, could you share your calculation please?It's an interesting stat, although the Soyuz has performed about 1,600 more flights more than the Falcon, so SX has a ways to go before they can really claim the crown.See, I used to buy this argument, but then the Russians released the Soyuz 2 in the 21st century Therefore, even if it seems intuitive, I'm skeptical whether 1500 means anything more than 70 in the reliability context.A better stat, as I posted, is to just consider active Soyuz models. Press question mark to learn the rest of the keyboard shortcutsCookies help us deliver our Services. They are different beasts, and any direct comparison is not really valid… The Soyuz has been in service (in several versions, to be clear… ) since the 1960’s. In that, Soyuz is around 150 flights and Falcon is 70 flights, with reliability as mentioned.Soyuz has had more flights than F9, but has also had more failures.Need someone who is good at stats and hasn’t had two wines, but I think there’s no significant difference-the error in the smaller F9 sample size would be quite large.
