A preview of the ISDC2009 presentation is now available – found at the NASA space flight Exploration Alternative forums
To sumarize some of the most strongest selling points of the Jupiter DIRECT shuttle derived launch vehicle are that, 1 – it increases NASA capability to deliver crew, supplies and new exploration hardware and infrastructure into space. 2 – At a lower operating and developement cost, close to $8000/kg versus the current systems $31000 per kilogram on the STS, and it will cost more than 20 billion dolars less the develope than the current Constellation system, the Ares I and V. And 3 – will eliminate the gap in our ability to launch and deliver crew to the ISS while maintaining the highskilled labor force at MSFC and KSC, a political requirement for any proposal of this scope. All of this while fitting nicely into NASA current budget, who doesnt want to save 20 billion dolars? Go watch the presentation.
