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.

Engineering Analysis and White Box Testing of High Fidelity Analysis Simulation
Analyzed dynamical performance of Guidance, Navigation and Control (GN&C) software for the Space Based Infrared System (SBIRS High) in a high-fidelity analysis simulation environment. The spacecraft is 3-axis stabilized in GEO orbit.
Implemented various on-orbit scenarios (orbit insertion, orbit adjust, attitude adjust, housekeeping) to determine if GN&C systems functioned according to designed specifications.
Recommended changes and documented results to correct errors and design flaws. This also served as a benchmark for flight software releases and as a baseline to insure the proper implementation of the flight software when bench tested with actual spacecraft hardware.
Researched space vehicle mass properties to insure GN&C simulation parameters matched finite-element model.

07/1990-07/1997-Lockheed Martin/GE Aerospace
Systems Engineer/Analyst, Software Developer
System Rearchitecture, Program 470:
Worked on program to port legacy ground system code from Fortran and C to C++. Used PERL to locate and organize system file information. Platforms used were both Sun workstations and HP workstations. Used SED/AWK to locate system file information.
Systems Integration, Program 607 (Engineering Analysis Group):
Developed phase-locked loop model in MATLAB to assist in system analysis.
Worked on team to resolve high-profile flat-spin anomaly of single-axis, spin-stabilized, on-orbit spacecraft. Rapid prototype models developed in MATLAB and Simulink.
Implemented JPL ephemeris software as part of study. Used Sed, Awk and Perl to process output files.
Developed MATLAB model to simulate RF transmission lobes represented by a Bessel function used during spacecraft cross-link acquisition.
Developed
The simulation was written in FORTRAN and developed on a Sun workstation, and used as part of a trade study.
IITS (Intra-theater Image Transmission System) Program:
Troubleshooting position to work on user-interface software for a battlefield facsimile transmission system.
Debugged and corrected critical failures to the software overcoming a lack of technical documentation for the code.
Inter-segment Interface (ISI):
Worked as a Maintenance Engineer to work off action items on software used to disseminate acquired spacecraft data to various sites for analysis. The code was written in FORTRAN and Cobol CICS on IBM 8090 XA Mainframe computers.
GEM (GE Ephemeris Management):
Operations & Maintenance Engineer responsible for legacy ground station software code.
Code used to determine ephemeredes of on-orbit spacecraft. Written in Fortran IV, H-extended on IBM 8060XA Mainframe computers.
