SURF@JPL: Announcements of Opportunity
Announcements of Opportunity are posted by JPL technical staff for the SURF@JPL program. Each AO indicates whether or not it is open to non-Caltech students. If an AO is NOT open to non-Caltech students, please DO NOT contact the mentor.
Announcements of Opportunity are posted as they are received. Please check back regularly for new AO submissions!
**Students applying for JPL projects should complete a SURF@JPL application instead of a "regular" SURF application.
**Students pursuing opportunities at JPL must be U.S. citizens or U.S. permanent residents.

Hazard Divert Size Sensitivity to Rocky Surfaces for the Sample Return Lander EDL Systems Team
(JPL AO No. 16130)

| Background: | The EDL Systems team is focused on coordinating the design of the Entry, Descent, and Landing system for the Sample Return Lander project as well as assessing design margin and risk and identifying robustness opportunities. Student will assist the EDL team in assessing statistics of landing on rocks of varying sizes and the sensitivity of the divert size needed to avoid dangerous rocks. | ||||||||
| Description: | The EDL systems team is currently assessing the risk of surface rocks to the lander at touchdown as well as mitigation strategies such as hazard detection and avoidance (i.e. short diverts to avoid surface hazards) to further reduce the risk of rocks to landing success. During the summer of 2024 the EDL team is seeking support to use existing MATLAB code and well-understood rock models to quantify the sensitivity of hazard divert size and guidance knowledge to rock risk for rock fields of varying severity. The student will report 99%tile numbers for rocks within the lander footprint for various rock fields as well as 99%tile statistics for diverts needed to avoid dangerous rocks. | ||||||||
