NASA CSLI Payload Design
Designed a miniaturized CubeSat system for measuring greenhouse gases on exoplanets. The project included full mechanical design of a 1U CubeSat frame, sensor integration, deployment mechanism, and data-logging system. The project aligned with NASA’s CubeSat Launch Initiative (CSLI), emphasizing feasibility for deployment as a ride-share payload on a larger interplanetary mission.
Technical Insights
Engineered a lightweight aluminum CubeSat chassis with removable panels and internal mounting rails.
Integrated Arduino, gas sensors, battery pack, motor-actuated door, and Bluetooth communication module.
Designed an altitude-triggered deployment mechanism using an altimeter + motor to open the top hatch.
Modeled atmospheric descent behavior and incorporated an Exo-Brake parachute to reduce velocity.
Implemented real-time data transmission to a remote station.
Design Highlights
Compact mechanical layout fitting all electronics into a constrained 10×10×10 cm frame.
Hinged motorized door enabling automated sensor exposure during descent.
Protective internal box for electronics to reduce shock and vibration damage.
Clean SolidWorks assembly and exploded views for documentation.
challenges and impact
Challenge: Designing a reliable deployment mechanism within tight mass and space constraints.
Impact: Demonstrated the feasibility of low-cost atmospheric sensing during planetary descent.
The prototype and documentation reinforced systems-engineering, cross-disciplinary design, and rapid prototyping skills.
