STEM Information Reviewer
Reviewed various types of STEM information for high school techbook design project. A techbook is an interactive internet encyclopedia, complete with textbook information, assignments, objectives, and linked resources.
Reviewed, edited, and made recommendations for Physics concepts documents using the Next Generation Science Standards (NGSS) guidelines, consisting of the following standards: Performance Expectations, Disciplinary Core Ideas, Crosscutting Concepts, Science & Engineering Practices, and Connections to Common Core State Standards.
Added upgrades from previous editions of techbooks to Asset Management database, after review corrections were made. Designed some sample problems for students to solve.
Quality assured end-user versions of high school web based Physics and Earth & Space Science techbook concepts.
Updated Asset Management database taxonomies with U.S. state standard concepts for use in designing high school techbooks.
Evaluated and quality assured content of Core Interactive Text Earth & Space Science files of techbooks for scientific content accuracy, instructional design, and grammar/spelling/clarity.
Jackson & Tull 2007-2011
Sr. Operations Engineer and Test/Field Engineer
Performed electrical integration and testing of various spacecraft hardware components in support of NASA’s Hubble Space Telescope (HST) and other missions.
Performed testing of flight hardware, flight software, databases and upgrades for HST operations and pre-launch Servicing Mission support using life-sized HST Simulator called the VEST.
Wrote, configured and updated scripts and telemetry pages to optimize VEST operation.
Tested ground system and database updates and wrote Work Order Authorizations to document testing steps.
Tested electrical components and circuit boards using oscilloscopes, breakout boxes, and multimeters.
Supported Electromagnetic Interference and Thermal Vacuum chamber testing of flight components H/W.
Performed inventory for spacecraft components in manufacturing building.
Computer Sciences Corporation 1992- 2007 Sr. Sub-System Engineer, Landsat 4/5 Earth Imaging Satellites Flight Operations
Served as the lead and assistant sustaining engineer for the satellites Landsat 4 and 5, planning and executing non-routine spacecraft operations, as well as performing UNIX workstation database administration.
Analyzed daily plots and telemetry pages for the Attitude Control System and Propulsion System data for low Earth orbiting & imaging satellites;
Major accomplishments include:
Modeled groundtrack effects & executed 3 Inclination maneuvers as needed for major spacecraft orbit changes.
Modeled, scheduled, executed, and did post-data analysis on over 150 spacecraft orbit adjusts.
Thirteen yearly updates of the spacecraft clock(s), including 3 leap second updates.
Contaminant removal (outgassing) from the Thematic Mapper, a data-gathering spacecraft instrument to reduce blackbody count in images and improve overall quality of the data.
Member of decomissioning team that successfully lowered the Landsat 4 into a safe, nonconflicting orbit for deactivation.
Technical lead accomplishments:
Trained and certified 12 new on-line engineers in daily flight operations activities such as ephemeris generation, stored command QA, spacecraft health & safety, star catalog generation, routine daily ops; Task lead for 4 on-line engineers.
Wrote and updated spacecraft operations engineering procedures according to ISO 9001-2000 standards.
As part of debris collision avoidance team, corresponded with debris tracking groups to identify debris near spacecraft orbit and prepare spacecraft in case action was needed to avoid a collision.
Adjusted/created masking coordinates for International Ground Station antenna tracking to assist other countries in pointing of their antennas to gather image data from passing spacecraft.
Served on Configuration Management Control Board.
Software/hardware testing accomplishments:
Wrote and updated UNIX scripts to format, automate, transfer and archive OASYS (orbit modeling software) input/output between spacecraft ground system and Solaris workstations;
Upgraded two OASYS workstations to Solaris windows platform (Pentium) from SCO platform (486) and insured the transfer of all relevant scripts, archive data, and flight dynamics data; Certified new workstations for use with ground system.
Tested new version of OASYS, documented changes/corrections, and certified new version for spacecraft flight dynamics products, imaging scheduling products, and antenna pointing output products.
Tested/updated spacecraft on-board computer telemetry limits monitor and real-time sequences as needed to enable spacecraft to respond to anomalous conditions when not in contact with flight operations.
Handled non-routine spacecraft onboard computer updates; served on analysis teams involved in the investigation and resolution of spacecraft anomalies and/or engineering operations improvements requested by customers.
On-Line Engineer, Landsat 4/5 Earth Imaging Satellites Flight Operations
Monitored earth orbiting spacecraft in real time to ensure health and safety for Landsat 4 and 5.
Generated ephemeris products using OASYS UNIX software and performed Quality Assurance.
Checked stored commands, and teamed with flight controller for commanding QA.
Produced two line elements (TLE’s) for IRS-C, IRS-D, ERS1, ERS2 earth orbiting spacecraft.
Performed routine spacecraft vector conversions, tape backups and plots of engineering data.
Weekly responsibilities included star catalog generation, generation of stored command scheduling products, OASYS computer file backups, and weekly plots.
Associate Member, Technical Staff, Hubble Space Telescope Project
Performed Operations & Ground Systems (Code 441) HST servicing mission scheduling duties, including: interacting with managers for weekly/monthly update of milestone status; Printed, copied and distributed the updated schedules; and providing information to the Master Schedule built in Primavera format.
Installed configuration management software used to track HST Ground System updates (called AXIS) on individual PCs, tested the installations, kept the system up to date, wrote user’s manual on how to use the software.
Recorded and updated minutes/action items for Guide Star Acquisition and other technical meetings in support of 1st HST Servicing Mission.
Archived/retrieved HST subsystem telemetry data from the VAX mainframe using 8mm and 9mm tapes.
