Dell is going to start shipping machines with Ubuntu pre-installed.
My press guy also runs a PAC that is trying to legalize Texas Hold ‘Em in Texas. Should be quite a show at the Texas Capitol tomorrow.
Here is my Space Access presentation:
I asked Robin about her half-price contract with Constellation Services and she says it does not include a test flight, so perhaps if we are not first to buy that, we can have half as many players to get to the trip for two around the Moon.
John Carmack’s announcement of a modular rocket that can reach suborbital space for $25,000 per module is revolutionary. Each module can independently reach suborbital space. Group the modules together and any size or shaped payload can reach suborbital space. The cost to get to space is $250 per module in fuel costs.
In a video that John said will be posted to his web site, he showed the modules being hooked together in a square arrays. These arrays can then be stacked for staging.
He predicts that he will produce the Armadillo orbital “Sputnik” which John also referred to as Mitchell Burnside-Clapp’s DYANN–Do You All Notice Now?
There are two revolutions here. The first is an open source garage revolution. With a small warehouse and a budget closer to Charlie Farmer’s in Farmer Astronaut than COTS winners RpK and SpaceX, Armadillo in a humble, matter-of-fact tone is brashly announcing an orbital program.
The second is the price of the revolution. At $25,000 per module, the capital cost per delta V is unprecedented and substantially lower than RpK or SpaceX.
This revolution was incrementally developed in plain sight and demonstrated in plain sight. No one thought Carmack’s Pixel and Texel were minimum concept proofs for a 64-module version. No one thought that by looking at the specifications they were seeing the ultimate cheap first stage and second stage and third stage.
Carmack thinks he can get the mass ratio down from 27 to 15 with some low cost evolutionary modifications. At 15-1, he can loft “Pixel 2” onto a suborbital trajectory with a 64-module first-stage lifter made up of 16 Pixels arrayed in a 4-4 grid or 8×8 single modules. Pixel 2 will be full of fuel and be the second stage. On top of Pixel will be a single module with a 25 lb. payload that will make it all the way to orbit. The cost for this delivery? The capital costs would be about $1.7 million if he can stay under $25,000 per module. If only the first stage is reusable, the cost per flight would be $150,000. If the first and second stage are reusable, the cost per flight would be $60,000. For a three stage system, that is a not very revolutionary price of $2400 per pound to orbit (albeit revolutionary vs. old space of $10,000+ per pound though.)
If they achieve a two-stage to orbit system where the second stage is also reusable, that would deliver a 100 lb payload to orbit for $35,000. That is roughly half fuel and oxidizer and half capital assuming a 100 flight lifetime. $350/lb is revolutionary. If this could be scaled up to Spacex Falcon IX payload size of 22,770 lbs., that’s $8 million or $22 million for a Falcon IX heavy sized payload of 62,500 lbs. An array of 100×100 modules supporting a second stage array of 25×25 modules boggles the mind and would cost $265 million in capital costs at $25,000 each. The flight rate assumptions would not be invalidated, however, because the vehicle could be broken up to support the suborbital tourism industry and smaller orbital payloads.
On the optimistic side, this price is before mass production. This mass ratio is before switching to methane (a 10% improvement in ISP over alcohol and a 50+% fuel price drop too). Google revolutionized servers by using modular white box CPUs. Now Carmack is making a bid to do the same thing. Nevertheless, Henry Vanderbilt cautions me that there is a long way to go from a view graph to orbit.

A wide plane requires a bunch of successively stronger connectors moving inward and results in very little additional payload delivered by the outside modules. This is especially true with a square grid which require more connections moving in from the corners than a hexagonal one. Other possibilities are more stages so connections are shorter and more vertical and larger, taller modules for lower stages.
Here’s an interesting piece that says it’s hurting small investors:
Today, it is much harder to get in on the firms that could be the next Home Depot, unless you are a super-wealthy investor that can participate in private equity deals. According to BusinessWeek, the median market cap of a company going public was $52 million in the mid-1990s. Today, it’s $227 million. This means that average investors are increasingly shut out of a company’s emerging growth stages, where they would, yes, take the most risks, but also could reap the biggest returns.
The most costly provision, Section 404, forces auditors and executives to sign off not only on the accuracy of financial statements, but also on a company’s internal controls. The unaccountable Public Company Accounting Oversight Board created by the law has defined “internal controls” very broadly, to include a firm’s software and other items that have little relevance to financial statements. Some say the law should be called the Accountants Full Employment Act.
As usual, hard cases make bad law. This gross overreaction to the Enron debacle can only make it harder for space entrepreneurs to raise money. Here’s hoping for some reform.

When you call Earthlink to cancel an account that you’ve had for years, but haven’t used for years, and for which they’ve been getting hundreds of dollars per year forever, they put you on hold forever.
Guess I should have chosen another option…
