NASA has decided to use the Atlas V, with 4 strap-on solid rocket boosters to launch MSL. This is the same rocket that launched MRO (no solids) and New Horizons (5 solids).
Cost: $194.7 million, less than half the price of the Titan IV which would have been needed a few years ago. Rocky Mountain News article NASA press release |

In a brief 'still on holiday' pop-head-around-door
The RD180 is two exhausts, but one engine I believe. Doug |

The RD180 is two exhausts, but one engine I believe. Right, the same goes for the RD-170, four nozzles. You can't really say that's four engines and four times as likely to fail as it only has a single set of turbopumps so for all practical purposes it's the same as having a larger, single-nozzle engine (say F-1). A little heavier than the latter, but easier and cheaper to produce (not to mention fewer combustion stability issues). -------------------- |
