Anonymous Coward User ID: 45680792 United States 12/22/2015 02:54 AM Report Abusive Post Report Copyright Violation | I think it's weird they would triumphantly live stream this 'land' landing, considering how the barge landings have gone thus far. Quoting: woowoo80 Well they were pretty confident they could pull it off on solid ground. Apparently their confidence was justified. OK so ... I've been out of the loop on the whole space exploration thing ... pretend I just got here from 1995 (in so many ways, I did) ... I followed the Space program from Sputnik until today - without fail. Gagarin and Valentina are my heros. Considering the crap tech they had then, I still think they did much better in the 60's than they are doing now. I wish $$$$$$ Musk best of luck. SpaceX is a commercial venture. He is doing this for profit not science. I don't think he's doing it only for profit. He's doing something that he is very interested in. People like him are dreamers and doers. People like him come along once in a while and they change the world. I think it's much more than about money to him. |

He made his own money and then decided to do Tesla and SpaceX. SpaceX in an incredible and risky undertaking. Plenty of people around the world have had much more money, but they don't do things like SpaceX. He's doing it because he can, in my opinion. I don't think he set out to become rich with SpaceX. I'll bet he's doing it because he's really interested in this. Whatever the reason, it's an incredible thing they've done. |

Quoting: Anonymous Coward 71011404 Seems the right introduction to the Trump era. not correct maybe;) Thread: 1st HISTORIC ROCKET LANDING was NOT done by SpaceX, but by Blue Origin in NOVEMBER 2015!!!! Blue Origin was first, but its rocket wasn't going as high and or fast as SpaceX's "Regardless of what the word rocket means to you, Blue Origin's achievement is still impressive. Landing a rocket vertically after it reaches the edges of space is an incredible challenge that no one has quite mastered before. The feat belongs in the record books, though it's unclear the exact record that Blue Origin now holds." [link to www.theverge.com] Last Edited by Jozo on 12/22/2015 06:06 AM |

Blue Origin was first, but its rocket wasn't going as high and or fast as SpaceX's It's apples and oranges really. Blue Origin's flight was purely sub-orbital; it didn't need any horizontal velocity. SpaceX's accomplishment was the first time the first stage of an orbital rocket had ever been safely and propulsively returned to earth. Landing the first stage of an orbital rocket is more impressive because its job wasn't to just fly straight up, but to deliver cargo into orbit by building up horizontal velocity before releasing the second stage, then reversing direction and flying all the way back to the launch site for a vertical landing. It required far more power and more precision. So, Blue Origin, first to land a purely sub-orbital rocket. SpaceX, first to land the first stage of an orbital rocket.

Dr. Astro (OP) Senior Forum Moderator User ID: 55240075 United States 12/22/2015 09:12 AM Report Abusive Post Report Copyright Violation | Is it cost effective to use this approach? At the end of the day this is what its all about. $$$ per weigh of payload. Quoting: Anonymous Coward 50074510 Such approach implies refurbishing and rocket having to carry more fuel and equipment (less payload weigh available). The Falcon 9 can be used in a disposable mode if the payload demands it, but it should be far cheaper to refurbish the rocket than build a completely new rocket each time. Looks like it will at least need a new paintjob each time though ;) The Falcon 9 Heavy will use three core stages which will all fly back independently to the Cape after launch. It will be capable of delivering much more payload to orbit as well. It gives me chills to think that last night we just got a big step closer to the above preview video. They have been hard at work building the new Falcon 9 Heavy pad out at 39A. Last Edited by Astromut on 12/22/2015 09:14 AM |

Dr. Astro (OP) Senior Forum Moderator User ID: 4211721 United States 12/22/2015 11:05 AM Report Abusive Post Report Copyright Violation | Question for Astro, or anyone that knows. In the future will this reusable rocket be bringing back astronauts? Or is it just the rocket that lands and the astronauts use the old reentry method? Quoting: Anonymous Coward 30385575 It's just the rocket that lands, at least at first. Rockets generally work by staging; the first stage comes off when it's almost out of fuel, then the second stage starts. Dumping the first stage dumps a lot of dead weight from empty fuel tanks and what are now an excess number of engines. The second stage carries the astronauts the rest of the way into orbit. In the case of the falcon 9 the first stage separates while it still has just enough fuel left to reverse course and get itself back to Cape Canaveral. This is possible even with only a little bit of fuel left because the less fuel a rocket has, the greater the acceleration you get from the engines since you're hauling a lot less mass. Compound this with the fact that the first stage is no longer carrying the heavy second stage on top of it and you actually find you have enough fuel to get all the way back to the Cape even though most of the fuel has already been spent. For manned launches the second stage will be carrying the crewed Dragon capsule. The capsule will do its mission and then come back the old fashioned way, but with a twist. You see, all crewed capsules have an "abort system," small rockets that carry the capsule away from the rocket in the event of a launch emergency. Usually these abort rockets are kept in a tower that sits on top of the crew capsule and is disposed of shortly before the rocket reaches orbit. The SpaceX dragon changes this formula by putting the abort rockets inside the capsule itself. It carries them all the way to orbit, and if they don't get used to abort the launch, they can be used to propulsively land the capsule at the space center after re-entry in a manner similar to the first stage. If for some reason the rockets don't fire up during the landing phase they can resort to using backup parachutes to come down in the water the old fashioned way. Here's an animation of what that will look like: |
