CAESAR: COMET ASTROBIOLOGY EXPLORATION SAMPLE RETURN

CLIENT

NASA Goddard Space Flight Center (GSFC) & Cornell University

SERVICES PROVIDED

Concept Design, Analysis, Project Management, and Testing Support

CASE SUMMARY

In collaboration with GSFC and Cornell University, Newton provided engineering support services to assist in a concept design and proposal that resulted in CAESAR’s selection as one of two NASA New Frontiers finalists.

CHALLENGE

NASA Goddard Space Flight Center (GSFC) and Cornell University requested specialized engineering support services for CAESAR’s concept development and proposal phase.

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

Newton assisted in a concept design and proposal that resulted in CAESAR’s selection as one of two New Frontiers finalists. The delivered engineering support services addressed important aspects of the structural analysis and landing loads derivation for the mission.

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, operational, and landing environments. To accomplish this, Newton:

• 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 to be used in various proposal activities.
