Falcon Heavy will fly |

Posted by WillD on Sat Apr 9 18:22:05 2011 SpaceX has upped the ante in their battle to gain a foothold in the US launcher market. The Falcon 9 Heavy is being touted as the most powerful rocket since the Saturn V (it isn't, unless they mean US launchers), and that it will deliver twice the payload of its nearest rival, the Delta IV Heavy, with almost half the cost.From SpaceX's Press Release IMHO this is a fairly interesting development as most of the community speculated that SpaceX would do to better develop their Hydrogen/LOX Raptor engine in an effort to improve geosynchronous transfer orbit performance for the fairly lucrative communication satellite market. But with the first Falcon 9 Heavy flying with the conventional Merlin powered, Kerosene/LOX fueled upper stage, and flying into a polar orbit from Vandenberg AFB in California, it seems possible they're taking aim at United Launch Alliance's USAF contracts for low earth orbit spy satellites. IMHO it's also interesting they will use propellant crossfeeding as that potentially means the two strap-on Falcon 9s will be discarded at lower altitudes and lower speeds than the Falcon 9 first stages that have been utilized to this point. That means those two boosters may stand a better chance of being reused because they'll be less susceptible to damage. Adding the Raptor upper stage to the Falcon 9H could push performance toward the 70 ton lower limit of NASA's proposed Space Launch System, which is slated to replace the Shuttle and the now defunct Constellation program. A pair of Falcon 9H launches, one each for an Orion or Dragon capsule, another for a lander, and a third with a stretched upper stage with a Raptor engine could very well put the very same lander NASA proposed to put on the Moon for a fraction the cost. It is possible a few tanker flights would be required to fill the Earth Departure Stage, and with prepositioning of fuel using very fuel efficient solar electric stages we could even reach Mars' moons with a reasonable number of launches. SpaceX certainly makes a strong case for having NASA forgo rocket design and construction and contracting out their launch services as was originally proposed for the FY2011 budget. |

As Mr. Musk has repeatedly noted, it is more than a little hypocritical that most Republican congressmen favor NASA's outdated and unreasonably expensive arsenal-based Spaceflight Center arrangement and the massive funding they require, while claiming to be pro-Business and anti-government. I guess as with everything the Republicans do, there's a big asterisk next to their support for business. Some of the Utah and Alabama congressional delegations are downright hostile to SpaceX, despite SpaceX being the only real corporation attempting orbital spaceflight right now.Given just how badly NASA is dragging its feet on downsizing the unwieldy Ares into the more modest requirements of the Space Launch System I'm ready to say 'Screw it' and join the argument against NASA providing its own launch services. We could provide federal funding for ULA's Advanced Centaur and Atlas V Phase II modifications while also providing SpaceX with some funding for their Falcon X concept, and likely still save money relative to NASA's hideously overpriced figures for a 70 to 130 ton (or tonne, the law isn't very clear) Shuttle Derived Launch Vehicle. I really liked the Jupiter when it was a sensible alternative to the monster Marshall Spaceflight Center turned the Ares into, but it now seems that no matter what NASA's course they'll be unable to get over the Freudian obsession with unaffordable rockets. At the very least, SpaceX having flying Falcon 9s has made for better Youtube videos: |
