Iranian officials say a rocket launch last weekend was merely a test, but U.S. military intelligence officials now see it as a failed attempt to put a satellite in orbit.
NASA engineers have come up with a dual shock absorber solution to the problem of excessive vibrations with the new Ares 1 rocket that will launch the agency's Orion space shuttle replacement.
To bring this sci-fi vision of 50-pound "micro-spacecraft" and 10-pound "nano-spacecraft" to reality, scientists have now invented a razor-thin skin that can protect craft against the extreme heat and intense cold found in outer space and withstand micrometeoroids hurtling at thousands of miles per hour.
Something beneath the surface is changing Earth's protective magnetic field, which may leave satellites and other space assets vulnerable to high-energy radiation.
NASA has delayed the launch of an unmanned spacecraft to the moon to scout for potential landing sites for astronauts.

EXPERIENCE:
Sr. Stress Analyst, Level V - Lockheed-Martin Corp., Space Systems Division, 5/01 - Present.
Performed stress analysis on satellite and missile programs involving both composite and metallic structures to ensure stability, strength and optical performance during fabrication, launch and operation. At different times, I served as overall Stress and technical lead. Projects at Lockheed have included: development of composite satellite bus structure and its autoclave tooling; optical metrology bench; active optic control hardware; rocket inter-stage and nozzle mounting joints, engine heat shielding, writing of stress analysis methodology standards
Research Assistant - Oregon State University – Mechanical Engineering & Forest Products, 10/91 - 6/00.
• Under NASA contract, developed theory of damage in laminated plate and applied it to damage tolerance analysis of composite aircraft. Wrote theory into nonlinear FEA code to simulate progressive damage growth. Developed novel fracture test to characterize composite. Programmed test controls using LabView. Simulation results correlated well with fuselage tests. • Under Boeing Commercial contract, developed bolted repair of large-scale composite fuselage damage using geometrically nonlinear FEA COSMOS/M). • Under Commercial Contract, R&D of natural fiber composites made from agricultural wastes. Developed press controls to optimize product economy and performance or simulate client press processes.
Mechanical Engineer - Structural Analyst: Boeing Defense & Space Group, 7/86 - 7/91.
• Developed a load-bearing conformal GPS antenna for fuselage integration. Predicted performance using nonlinear FEA. Developed and characterized dual-purpose dielectric-structural materials. • An aircraft structural health monitoring system was researched for fatigue, impact and corrosion detection and assessment. Established benefits and system requirements. Experimentally investigated optical sensor technology and its embedment in composite structure.
• Structural analysis and test of high performance ejection seat. Analyzed graphite/epoxy seat chassis, metallic catapult and cockpit integration assembly. Quantified body restraint loads.
