As an Amentum Space Exploration Division (ASED) intern, you will work alongside engineers and scientists on hardware development, payload integration & operations, laboratory & test operations, modeling & simulation, space environments, scientific research and propulsion systems for programs like Human Landing Systems, Space Launch Systems and the International Space Station!
Job Description
The Thermal Analysis Intern will support the Thermal/Fluids Analysis group within the Amentum Space Exploration Division at NASA Marshall Space Flight Center. The intern will work closely with thermal engineers to support ongoing space systems development projects through a combination of thermal insight activities and thermal analysis/modeling.
This position is intended to provide immersive engineering experience, with responsibilities split between the thermal analysis insight support and performing various analysis and technical documentation tasks. The intern will contribute directly to real NASA programs focused on the Human Lander System program, gaining exposure to hardware in a professional environment.
Typical projects may include organization of requirements documentation assessments from commercial partners, thermal analysis model development, and conducting thermal verification planning. These activities will be for hardware at various stages of its development.
Key Responsibilities

• Assist thermal engineers with thermal verification activities for proposed hardware designs of commercial partners and/or NASA
• Participate in review of technical data and requirements
• Perform thermal design and analysis using engineering tools, spreadsheets, and/or simulation software such as Thermal Desktop.
• Support development and maintenance of thermal models and test documentation.
• Complete and maintain proper trainings, as well as explicitly following safety procedures.
• Collaborate with multidisciplinary engineers and NASA personnel in a team environment.

Qualifications
Current enrollment in a Bachelor's, Master's, or PhD program in Mechanical Engineering, Aerospace Engineering, Chemical Engineering, or a closely related engineering discipline is required. You are expected to have a valid driver's license, have access to an automobile, and be able to drive yourself to work locations.

• NOTICE: Your state-issued drivers' license must be a Star License, since NASA's Marshall Space Flight Center is located on the Army's Redstone Arsenal, a federal installation.

Additional Requirements

• Strong interest in aerospace, thermal systems, heat transfer, and developmental testing.
