NASA University Student Launch Initiative (USLI)
Payload Team Lead – Senior Design Project
Fall 2025 – Spring 2026 | Colorado State University
Overview
Leading an 8-member payload team in CSU's NASA USLI Senior Design Team. The project involves designing a deployable payload system to collect and analyze a soil sample during the April 2026 NASA competition in Huntsville, Alabama.
Responsibilities include overseeing electrical and firmware development, coordinating with mechanical and vehicle teams, and managing project timelines to ensure successful integration and testing ahead of the launch. As the only electrical engineer on the payload team, I'm deeply involved in system design, component selection, and testing to meet mission requirements.
Key Contributions (Ongoing)
Subscale Electronics Design
Designed and implemented subscale payload electronics to capture in-flight sensor data. Integrated data acquisition and onboard logging, storing measurements to a microSD card using an Arduino Nano. Supported proof-of-concept launch to validate payload landing systems and characterize deployment and landing behavior.
Payload Subsystem Design
Designed, built, and tested a subscale payload for in-flight data collection during validation testing. Developed preliminary electrical schematics for the drill mechanism and defined system-level architecture. Established power budgets and validated them through reviews with industry engineers. Conducted initial hardware testing to verify subsystem performance.
Payload Autonomy & Firmware
Developed firmware architecture enabling autonomous payload operation. Defined communication protocols, GPIO mapping, and control logic for sensor integration and actuation. Implemented structured data handling for reliable onboard logging and post-flight analysis.
Project Management
Developed Gantt charts, coordinated electrical and mechanical efforts, and enforced milestone tracking. Standardized version control practices by introducing Git workflows and training resources for the programming team.
Impact
Advancing toward a fully functional payload system for flight demonstration at the NASA USLI 2026 competition—highlighting integration of mechanical, electrical, and control subsystems in a rigorous aerospace setting. This work contributes to NASA's mission of fostering student-led innovation in launch vehicle design and advancing technologies relevant to future space exploration.
Skills
Level 1 High Power Rocketry (L1 HPR) Certification
Successfully obtained L1 HPR certification through building and launching my own high-power rocket. This hands-on experience with rocket construction, recovery systems, and launch operations directly informs my work on the USLI payload team.

Early Development
Original breadboard testing of all sensors included on the final competition payload
Prototype 1: Subscale Electronics Development
Prototype 2: Subscale Testing and Deployment
Subscale electronics, front-facing, that was in the payload body for subscale launches 1 and 2. Collects real-time clock data, altitude data, payload internal temperature, barometric pressure, and stores it to a microSD card. A buzzer is used as an indicator and a tactile button as a toggle.
Subscale 1 rocket being assembled
Payload landing after deployment at the test site in Hartsel. The parachute burnt up when the black powder charges fired, causing parachute failure. However, the deployment of the payload body was successful. The payload orientation system worked nominally and suffered no damages. The microSD card from this first launch was lost at this location but was not recovered.
