Time To Take Private Space Seriously

So sayeth The Economist:

Five years ago the idea that the private sector might have been capable of transporting cargo and people reliably into low Earth orbit was viewed as crazy. Much has happened since, and two things in particular. One was that Virgin Galactic, an upstart British firm, said it would develop a space-tourism business based around a craft that had cost only $25m to build. The other was that an equally upstart American entrepreneur called Elon Musk, flush from his sale of PayPal, created a company called SpaceX (whose Falcon rocket is pictured above, dropping its first stage on its way into orbit). He said he wanted to make it cheaper to launch people into space and wanted, ultimately, to send a mission to Mars—but that he would start by launching satellites.

It would be an understatement to say that both ventures were treated with scepticism. But they have now come far enough to be able to thumb their noses at the cynics. On September 3rd SpaceX signed a contract worth $50m with ORBCOMM, a satellite-communications firm. The deal is to launch 18 satellites for ORBCOMM’s network. Meanwhile, at the end of July, Aabar Investments, a sovereign-wealth fund based in Abu Dhabi, bought a 32% stake in Virgin Galactic for $280m. Aabar was not just interested in space tourism. It was also keen on a proposal to use Virgin’s White Knight launch system to put satellites into low Earth orbit. Will Whitehorn, Virgin Galactic’s president, said that one of the things which attracted Aabar was the fact that White Knight (an aircraft which lifts to high altitude a rocket that can then take either passengers or satellites onwards into space) could be flown from Abu Dhabi.

The “Giggle Factor” continues to dissipate.

An Impression Of The Protest

…from Matt Welch, who wandered out to the mall to see it..

[Late evening update]

Per the discussion in comments, a graphical tale of “left” versus “right” events on the mall.

Henry Vanderbilt (who should start a blog on space transportation and other topics) sends an analysis of the crowd size via email. He says it’s clearly six figures — hundreds of thousands: Continue reading An Impression Of The Protest

Is All Forgiven For Rich Rodriguez?

Probably not all — after all, he led Michigan to their worst season in school history last year. But today’s win over Notre Dame will go a long way. That game will be a classic.

Especially if they can win out, though I don’t know how likely that is. I have to say, though, that it’s nice to have a true freshman QB who is already playing like a Heisman candidate in his second game..

ULA Unleashed

I was hoping I’d be back in California in time to attend the AIAA meeting this coming week in Pasadena, because it looks like it will have some very interesting (and perhaps politically explosive) technical papers. As Clark Lindsey notes, the United Launch Alliance has apparently been spending a lot of IR&D on some (up to now) politically incorrect ideas. They’ve developed a complete lunar architecture concept that uses only EELVs and derivatives of them for depots and landers (though they note that other launchers could complement it as well).

As Clark did, I’m going to repeat the introduction from Frank Zegler’s paper, in particular:

The present ESAS architecture for lunar exploration is dependent on a large launcher. It has been assumed that either the ARES V or something similar, such as the proposed Jupiter “Direct” lifters are mandatory for serious lunar exploration. These launch vehicles require extensive development with costs ranging into the tens of billions of dollars and with first flight likely most of a decade away. In the end they will mimic the Saturn V programmatically: a single-purpose lifter with a single user who must bear all costs. This programmatic structure has not been shown to be effective in the long term. It is characterized by low demonstrated reliability, ballooning costs and a glacial pace of improvements.

The use of smaller, commercial launchers coupled with orbital depots eliminates the need for a large launch vehicle. Much is made of the need for more launches- this is perceived as a detriment. However since 75% of all the mass lifted to low earth orbit is merely propellant with no intrinsic value it represents the optimal cargo for low-cost, strictly commercial launch operations. These commercial launch vehicles, lifting a simple payload to a repeatable location, can be operated on regular, predictable schedules. Relieved of the burden of hauling propellants, the mass of the Altair and Orion vehicles for a lunar mission is very small and can also be easily carried on existing launch vehicles. This strategy leads to high infrastructure utilization, economic production rates, high demonstrated reliability and the lowest possible costs.

This architecture encourages the exploration of the moon to be conducted not in single, disconnected missions, but in a continuous process which builds orbital and surface resources year by year. The architecture and vehicles themselves are directly applicable to Near Earth Object and Mars exploration and the establishment of a functioning depot at earth-moon L2 provides a gateway for future high-mass spacecraft venturing to the rest of the solar system.

Frank would probably never have been able to publish a paper like this when he was at Lockheed, which still has a major stake in Orion, and the Boeing people are similarly constrained for now, as long as they hold out hope for continuation of their upper-stage work on Ares I. But Frank is at ULA now, and ULA owes NASA nothing, particularly after having their launchers spurned when Griffin came in. That, combined with the fact that Ares’, and indeed Constellation itself’s blood is in the water means that they can come out boldly with the kind of innovation that NASA has been avoiding for over four years, and kick Constellation while it’s down. If we get back to the moon with a NASA program, it’s going to look a lot more like this than the current plans.
