NSS hails NASA budget for 2005 (November 23, 2004)
The National Space Society today hailed Congress on its foresight to fully fund the NASA budget for FY2005. "NSS members and grassroots supporters of space have a right to be proud," said NSS executive director, George Whitesides. "It was their vocal support - including the 1700 letters submitted in the final week of deliberations - that may have been the tipping point for this space victory."

NASA'S X-43A Scramjet Breaks Speed Record

November 16, 2004

Release: 04-59

NASA's X-43A research vehicle screamed into the record books again Tuesday, demonstrating an air-breathing engine can fly at nearly 10 times the speed of sound. Preliminary data from the scramjet-powered research vehicle show its revolutionary engine worked successfully at nearly Mach 9.8, or 7,000 mph, as it flew at about 110,000 feet.

The high-risk, high-payoff flight, originally scheduled for Nov. 15, took place in restricted airspace over the Pacific Ocean northwest of Los Angeles. The flight was the last and fastest of three unpiloted flight tests in NASA's Hyper-X Program. The program's purpose is to explore an alternative to rocket power for space access vehicles.

"This flight is a key milestone and a major step toward the future possibilities for producing boosters for sending large and critical payloads into space in a reliable, safe, inexpensive manner," said NASA Administrator Sean O'Keefe. "These developments will also help us advance the Vision for Space Exploration, while helping to advance commercial aviation technology," Administrator O'Keefe said.

Supersonic combustion ramjets (scramjets) promise more airplane-like operations for increased affordability, flexibility and safety in ultra high-speed flights within the atmosphere and for the first stage to Earth orbit. The scramjet advantage is once it is accelerated to about Mach 4 by a conventional jet engine or booster rocket, it can fly at hypersonic speeds, possibly as fast as Mach 15, without carrying heavy oxygen tanks, as rockets must.

The design of the engine, which has no moving parts, compresses the air passing through it, so combustion can occur. Another advantage is scramjets can be throttled back and flown more like an airplane, unlike rockets, which tend to produce full thrust all the time.

"The work of the Langley-Dryden team and our Vehicle Systems Program has been exceptional," said NASA's Associate Administrator for Aeronautics Research J. Victor Lebacqz. "This shows how much we can accomplish when we manage the risk and work together toward a common goal. NASA has made a tremendous contribution to the body of knowledge in aeronautics with the Hyper-X program, as well as making history."

The flight was postponed by one day when repair of an instrumentation problem with the X-43A caused a delay. When the preflight checklist was resumed, not enough time remained to meet the FAA launch deadline of 7 p.m. EST.

Today, the X-43A, attached to its modified Pegasus rocket booster, took off from Dryden Flight Research Center at Edwards Air Force Base, Calif., tucked under the wing of the B-52B launch aircraft. The booster and X-43A were released from the B-52B at 40,000 feet and the booster’s engine ignited, taking the X-43A to its intended altitude and speed. The X-43A then separated from the booster and accelerated on scramjet power to a brief flight at nearly Mach 10.

NASA's Langley Research Center, Hampton, Va., and Dryden jointly conduct the Hyper-X Program. NASA's Aeronautics Research Mission Directorate, Washington, manages it. ATK-GASL (formerly Microcraft, Inc.) at Tullahoma, Tenn., and Ronkonkoma, N.Y., built the X-43A aircraft and the scramjet engine, and Boeing Phantom Works, Huntington Beach, Calif., designed the thermal protection and onboard systems. The booster is a modified first stage of a Pegasus rocket built by Orbital Sciences Corp, Chandler, Ariz.

Secondary Profit Generators for Moon and Mars Bases

Lunar and Mars base planners concentrate on one or two economic drivers to justify a base. This is like the "killer app" in the computer world, the single indispensable application that justifies the computer purchase. "Secondary profit generators," numerous economic activities that make a complex lunar or Mars base work, have received less attention.

Trade with Earth is a special case. Due to Earth's deep gravity well, transportation costs are far from reciprocal. Earth industry produces vital items unavailable elsewhere; however, Earth's large population represents a huge market for offworld products.

Space commerce among bases on the Moon, Mars, and elsewhere in space brings opportunities in transportation, sales, legal services, and trade in minerals and volatiles, to name a few.

As bases specialize, an interbase economy will develop. Bases can specialize in power production or construction, for example. Precious volatiles could be traded, as long as they remain onworld.

Intrabase economy, or commerce within a single base, opens up a range of small business possibilities including repair shops, laundry, professional services, and others.

The more secondary profit generators a base can develop, the stronger and more resilient the base economy will be. Settlements initiated as "company towns" will transition to diversified economies. Ultimately, the aggregate of secondary profit generators could dominate base balance sheets and do away with the need for a single economic driver to make a base a viable, going concern.
