Jeff Greason of XCOR Aerospace gave an overview of his company’s work at Space Access this morning. He noted that the company actually turned a profit last year, with revenues of approximately $3.8 million; the profit was an artifact of the timing of the contracts it was working on, and he said he doesn’t anticipate being profitable again this year, although revenues should be similar to 2006. Because XCOR doesn’t have an independently wealthy founder or patron, “we have to flip burgers for a living”: doing developmental work for a number of government and commercial customers. XCOR selects that work based on the problems XCOR is facing for its own projects, thus in effect getting a customer to pay for XCOR’s R&D. “We have turned R&D from a cost center to a profit center,” he said.

XCOR is working on three engine projects: a 50-lbf engine for RCS applications, a 1,500-lbf engine for the Rocket Racing League (RRL), and a 7,500-lbf engine with ATK for NASA. The efforts are all going well, and Greason said that the RRL engine work, which had been going slowly at the request of the customer, is now ready to go back into high gear. XCOR is also still developing its own suborbital vehicle design, although Greason gave few specific details about the project, and no development schedule or funding information (although he did say later that have not finished raising all the money they need for the effort, but are close.) He did say that XCOR will, in the future, offer more details about its long-term roadmap, in much the same way Masten Space Systems does. “Suborbital is not the last step on our road.”

John Carmack gave an extensive status report on Armadillo Aerospace at the Space Access conference yesterday. Armadillo’s near-term emphasis is on preparing for the 2007 Lunar Lander Challenge, having made some upgrades to Pixel and Texel, such as stronger landing legs. They are also working on their modular vehicle approach: putting together progressively more capable vehicles by adding identical modules, which consist of a pair of LOX/ethanol propellant tanks mounted on top of an engine. A four-module vehicle would be just powerful enough to send a small payload to 100 kilometers; such flights could take place by the end of this year or early next year from Spaceport America in Armadillo’s best-case scenario. A nine-module version, with a capsule on top, could be used for commercial human suborbital flights; Armadillo is looking to building a barebones capsule but also is in talks with an unspecified company to develop it. Farther down the road Carmack envisions an orbital vehicle with two or three stages and as many as 64 modules, something that has raised more than a few eyebrows among industry insiders. “When I talk about these larger-scale operations to most of the people in the industry, I always get ‘that look’, whenever I talk about 64 engines or 64 modules,” he said. “It’s an initial knee-jerk reaction, but when you come down to it, I don’t think it’s justified.”

Along with the technical plans, Carmack also addressed the business side. Armadillo has always been difficult to classify: they have significant facilities and equipment, but rely almost exclusively on volunteer labor, and have been funded mostly out of Carmack’s checkbook, to the tune of $3 million to date (with a burn rate of about $500,000/year). Is Armadillo a fledgling business or just an expensive hobby? Carmack did say that they have been looking at a number of commercial opportunities, and while not many of them “have turned into real money” they are seeing an increase in outside revenue over the last few years. With Carmack saying that he can continue to support Armadillo’s efforts out of his pocket “until the bottom drops out of the videogame market”, he doesn’t seem to be in a big rush to close deals, and said that even with a huge infusion of money it would be difficult for them to go more than two or three times faster than their current pace. “When the capability is demonstrated, the business case is just going to close itself.”

“We’re absolutely going to be carrying people to space, whether it’s next year or the year after,” he said. He admitted that he has made similar statements in the past, but this time “we are making steady, incremental progress towards that.”

A roundup of a few items going on in the field not associated with the Space Access conference:

• Charles Simonyi announced that he will speak with high school students in the US from the ISS during his trip to the station, using the amateur radio link on the ISS.
• The Scotsman reviews a new book about space tourism published in the UK, Destination Space: Making Science Fiction a Reality. The book, published by Virgin Books (wouldn’t you know), is due out in the US in a couple of months, according to Amazon.com.
• Two cosmonauts heading to the ISS on the next crew rotation said they would have no problems conducting an EVA with a tourist, provided the tourist had received some training.
• Space Adventures has hired a PR agency in order to support “additional promotional opportunities” associated with Simonyi’s flight next month. The firm, Susan Magrino Agency, plans to target “luxury and general-interest publications” and broadcast outlets. Don’t forget us online media…
