COMET ASTROBIOLOGY EXPLORATION SAMPLE RETURN (CAESAR)

CLIENT

NASA Goddard Space Flight Center

SERVICES PROVIDED

Engineering Services: concept design, analysis, project management, and testing support.

CASE SUMMARY

Newton's engineering support assisted in a concept design and proposal that resulted in CAESAR's selection as one of two New Frontier finalists. The in-depth analysis, which includes a detailed nonlinear analysis of landing loads, demonstrated to the proposal review panel that the CAESAR project was aware and prepared for launch, operating, and landing environments.

CLIENT REQUEST

During the project's concept development and Proposal Phase, Cornell University and NASA GSFC required specialized engineering support for CAESAR.

Newton delivered engineering services to address important aspects of the structural analysis and landing loads derivation for the mission.

CAESAR is planned to be the farthest-reaching sample return mission in history. The mission is to collect a sample from a comet's surface and return it to Earth in pristine condition for the most extensive study of comet material ever done.

SOLUTION

• Performed analyses and testing to determine impact loads upon sample return to Earth;

• Performed structural analysis (including nonlinear impact analysis), trade studies, and optimization analyses;

• Guided design changes to increase the robustness of the design, ensuring adequate margins of safety, and optimizing mass;

• Provided logistics support for testing including instrumentation, test set up, documentation, and statistical analysis of test results;

• Provided documentation, media, and data to highlight the strengths of the CAESAR Mission.
