These additional processing steps increase the overall size and complexity of the instrument package. At the same time, it is clear now that an understanding of the chemical environment surrounding potential biosignatures is critical to rationally select proper sample handling and detection methods. This information is also crucial in the process of interpreting the resulting data sets obtained during the analysis. This proposal addresses these points by integrating a universal conductivity-based detector into a lab-on-a-chip system that can search for salts and biomarkers simultaneously while greatly simplifying both the instrument and its operation.Our proposal is built upon three key research objectives: O1 - Development of protocols for simultaneous analysis of inorganic and organic ions with ME-C4D. (Initial TRL 2, final TRL 4) O2 - Demonstration of analysis on inorganic and organic ions by ME-C4D in relevant environmental samples. (Initial TRL 2, final TRL 4) O3 – Design of a miniaturized ME-C4D instrument dedicated to simultaneous analysis of inorganic and organic ions. (This work will leverage from instruments previously developed in our laboratory, initial TRL 3, final TRL 4) This effort will provide the capability to detect ionic species directly in liquid samples or following extraction from solid samples, or melting of ice samples (i.e. from the surface or jets of Enceladus or Europa). Samples are simply dissolved in the appropriate buffer and analyzed by microchip electrophoresis coupled to contactless conductivity detection. We will develop protocols for simultaneous analysis of both inorganic and organic ions with a single miniaturized instrument and without labeling. This new capability will provide a major leap forward in NASA's ability to obtain the chemical composition of Martian regolith as well as Europa's subsurface ocean. The ionic composition will help us understand the chemical processes and the possibility of past and present life in these targets highly relevant to future in situ missions.","destinations":[{"lkuCodeId":1546,"code":"INSIDE_SOLAR_SYSTEM","description":"Others Inside the Solar System","lkuCodeTypeId":526,"lkuCodeType":{"codeType":"DESTINATION_TYPE","description":"Destination Type"}}],"startYear":2016,"startMonth":6,"endYear":2019,"endMonth":5,"statusDescription":"Completed","principalInvestigators":[{"contactId":307756,"canUserEdit":false,"firstName":"Maria","lastName":"Mora","fullName":"Maria F Mora","fullNameInverted":"Mora, Maria F","middleInitial":"F","primaryEmail":"maria.mora@jpl.nasa.gov","publicEmail":true,"nacontact":false}],"programDirectors":[{"contactId":510275,"canUserEdit":false,"firstName":"Erica","lastName":"Montbach","fullName":"Erica N Montbach","fullNameInverted":"Montbach, Erica N","middleInitial":"N","primaryEmail":"erica.n.montbach@nasa.gov","publicEmail":true,"nacontact":false}],"programManagers":[{"contactId":431364,"canUserEdit":false,"firstName":"Shahid","lastName":"Aslam","fullName":"Shahid Aslam","fullNameInverted":"Aslam, Shahid","primaryEmail":"shahid.aslam-1@nasa.gov","publicEmail":true,"nacontact":false}],"coInvestigators":[{"contactId":374753,"canUserEdit":false,"firstName":"Peter","lastName":"Willis","fullName":"Peter A Willis","fullNameInverted":"Willis, Peter A","middleInitial":"A","primaryEmail":"peter.a.willis@jpl.nasa.gov","publicEmail":true,"nacontact":false},{"contactId":846,"canUserEdit":false,"firstName":"Aaron","lastName":"Noell","fullName":"Aaron C Noell","fullNameInverted":"Noell, Aaron C","middleInitial":"C","primaryEmail":"anoell@jpl.nasa.gov","publicEmail":true,"nacontact":false},{"contactId":259861,"canUserEdit":false,"firstName":"Karen","lastName":"Piggee","fullName":"Karen R Piggee","fullNameInverted":"Piggee, Karen R","middleInitial":"R","primaryEmail":"karen.r.piggee@jpl.nasa.gov","publicEmail":true,"nacontact":false},{"contactId":61456,"canUserEdit":false,"firstName":"Carlos","lastName":"Garcia","fullName":"Carlos D Garcia","fullNameInverted":"Garcia, Carlos D","middleInitial":"D","primaryEmail":"carlos.garcia@utsa.edu","publicEmail":false,"nacontact":false}],"website":"","libraryItems":[],"transitions":[],"responsibleMd":{"acronym":"SMD","canUserEdit":false,"city":"","external":false,"linkCount":0,"organizationId":4909,"organizationName":"Science Mission Directorate","organizationType":"NASA_Mission_Directorate","naorganization":false,"organizationTypePretty":"NASA Mission Directorate"},"program":{"acronym":"PICASSO","active":true,"description":"
The PICASSO Program seeks proposals for development activities leading to instrument systems in support of the Science Mission Directorate’s (SMD) Planetary Science Division. The objective of the program is to develop new technologies that significantly improve instrument measurement capabilities for planetary science missions (such as Discovery, New Frontiers, Mars Exploration, and other planetary programs). The PICASSO Program is intended to enable timely and efficient technology infusion into the MatISSE Program and eventually into flight missions. As such, the technology readiness level (TRL) that PICASSO supports is 1-4. It is the responsibility of the proposer to justify the entry and exit level TRL of the proposed technology. This program will permit appropriate funding to be applied at this early stage to develop and demonstrate key and enabling new technologies for planetary science missions, such as instrument feasibility studies, concept formulation, proof of concept, laboratory demonstrations, and advanced component technology development.
