Frozen_Heart Posted October 7, 2015 Share Posted October 7, 2015 that means that it *can* lift up 200ish tons to LEOThey plan to reuse the MCT/BFR from the start which very roughly halves the payload capacity. It won't even be close to 200 tons. Link to comment Share on other sites More sharing options...
Albert VDS Posted October 7, 2015 Share Posted October 7, 2015 They plan to reuse the MCT/BFR from the start which very roughly halves the payload capacity. It won't even be close to 200 tons.Really? I would like to see those calculations. Link to comment Share on other sites More sharing options...
Streetwind Posted October 8, 2015 Share Posted October 8, 2015 For the Falcon 9, estimates for payload capacity lost to reuse range from 20% (optimistic/barge landing) to 30% (pessimistic/RTLS). Definitely not 50%.And keep in mind that the thrust figure describes only a rocket. "MCT" is a whole architecture, not just a single vessel, and things like "100 tons to Mars surface" comes from old, early concepts and may not have survived the planning phase. It's a bit futile to speculate based on it.But, now that The Martian is in theaters in most countries, let's hope that SpaceX aims to ride on this hype-wave instead of waiting with the announcement until after return to flight Link to comment Share on other sites More sharing options...

As the want the BFR to be fully reusable i'm assuming that is both stages landing again. Second stage after 1 or more orbits. Link to comment Share on other sites More sharing options...
Streetwind Posted October 8, 2015 Share Posted October 8, 2015 Oh my, the internet is just awash with wild rumors and crazy speculation!The Fact: Chris B. defined the level of his excitement as "a 236 on a scale of 1-10"The Rumor: He strongly hinted that that number is not just any random number.The Speculation: Over at reddit, people are now discussing if it's possible that the BFR might be able to lift 236 metric tons to LEO, almost doubling up on the famous Saturn V.I can't say I have an opinion on whether or not it's possible or even sensible... but I can definitely say that I'm having so much fun right now following that discussion Aint this a time to be alive?

SargeRho Posted October 8, 2015 Share Posted October 8, 2015 Given that the BFR uses Methane instead of Kerosene, and the greater efficiency coming with that, wouldn't that mean that it loses less payload capacity for full reusability? Link to comment Share on other sites More sharing options...

SargeRho Posted October 8, 2015 Share Posted October 8, 2015 "Big Fracking Rocket" is the common way to say it. "Fracking Big Rocket" isn't the usual way, though both are grammatically correct as far as I know. Link to comment Share on other sites More sharing options...
sojourner Posted October 8, 2015 Share Posted October 8, 2015 236 is a pretty specific number for a rocket that doesn't even have a full up engine to test yet. Without knowing what that engine is going to actually produce thrust -wise, it's hard to estimate the payload capability of the completed rocket. Unless they are being very conservative and hope to increase that number as real data comes in to fill in the blanks. Link to comment Share on other sites More sharing options...
Kartoffelkuchen Posted October 8, 2015 Share Posted October 8, 2015 Interesting things seem to happen. Just a side-note, being part of L2 seems to be the best thing you can have at this time! I'm looking forward to the announcement! Link to comment Share on other sites More sharing options...
cptdavep Posted October 8, 2015 Share Posted October 8, 2015 Wouldn't expect an announcement too soon. Musk is a clever chap when it comes to PR (and everything), and he'll know that releasing details of his Mars ambitions while his rockets are grounded would be a massive own goal as the media wouldn't take it seriously. I agree with others, he'll wait for a successful 1st stage landing before releasing details of BFR and MCT. I think falcon is pencilled in to return to flight next month so it hopefully won't be long to wait! Link to comment Share on other sites More sharing options...

FishInferno Posted October 10, 2015 Share Posted October 10, 2015 can say to you, with a lot of confidence, everything one hopes SpaceX is, has been promising and may become, is more than you could have hoped for. We all know the forward plan, but I think we're all going to be blown away by just how big those plans are, even if only half of it becomes a reality.From the same guy that sent out that teaser tweethttp://forum.nasaspaceflight.com/index.php?topic=38593.0 Link to comment Share on other sites More sharing options...
CatastrophicFailure Posted October 16, 2015 Share Posted October 16, 2015 Latest news: still 6-8 weeks out:"Return Falcon-9 to Flight with Orbcomm-2 Mission to Test Rocket's Upper Stage"But does seem to confirm they'll be attempting a landing.

Kartoffelkuchen Posted October 17, 2015 Share Posted October 17, 2015 Yes, they'll try to land it, as far as I know. Though it's not clear if it will be RTLS or ASDS yet. II'm very thrilled for their RTF. Link to comment Share on other sites More sharing options...
bigdad84 Posted October 20, 2015 Share Posted October 20, 2015 Really looking forward to their RTF. Even crossed my mind about driving down there to watch it. How awesome would it be for them to have a succesful return to flight launch and then manage to land it on the barge. BAM! SpaceX is back better than ever.

Dkmdlb Posted October 20, 2015 Share Posted October 20, 2015 Best case, they follow it up with a couple more successful F9 flights, then a F9H demo flight with RTLS on the boosters, then a release of the Mars plans. 2016 is going to be a wild ride.

Frida Space Posted October 20, 2015 Share Posted October 20, 2015 The return to flight payload has been changed from the SES-9 satellite (now scheduled for the launch after the RTF) to the 11 small satellites (170 kg each) of the Orbcomm 2 mission. The Orbcomm satellites will be placed on a 650 km orbit and thus won't require a second burn by the second stage Merlin engine. After the deployment of the satellites, SpaceX will go ahead and test the reignition system of the redesigned second stage, so they will have an in-flight orbital test before they go ahead and launch SES-9, which instead will be deployed on a much higher orbit (35 000 km) that will require a second burn from the second stage.From what I understood, both Orbcomm 2 and SES-9 missions will use the redesigned Falcon 9 (v1.2), with fixes for the June mishap, plus longer second stage tanks, more powerful engines, densified propellant and other stuff.Coming up are also CRS-8 to the ISS (scheduled for sometime in January) and the Jason 3 NASA/NOAA/CNES/Eumetsat launch, which should be the last flight of Falcon 9 v1.1. SpaceX said they are aiming for 2/3 launches by the end of the year.Main source: spaceflightnow.com/2015/10/18/orbcomm-first-in-falcon-9s-return-to-flight-launch-queue/ Link to comment Share on other sites More sharing options...
