Brief Bio


Charles Malespin is the Chief of the Planetary Environments Lab (Code 699), and serves as the Principal Investigator for the Sample Analysis at Mars (SAM) instrument suite currently on the Curiosity rover in Gale Crater, Mars. Malespin additionally is the Gas Processing System payload element lead for the mass spectrometer on the New Frontiers Dragonfly mission to Titan, and is the Venus Mass Spectrometer (VMS) lead for the DAVINCI mission to Venus. He also serves as PI for CADMES (a Europa Lander sample delivery system), is the SAM operations lead, and is responsible for directing the SAM testbed program, including defining, prioritizing, and organizing all experiments prior to the sequence execution on Mars by the SAM instrument.


 

 

Current Projects


Sample Analysis at Mars (SAM) Principal Investigator

Mars

Malespin leads a team using an interdisciplinary treatment of SAM data, both science and engineering telemetry, to produce expert interpretation of surface mission science products. He is an expert in understanding the SAM instrument and led the development, testing, and interpretation of several major experiments that have made some key discoveries for MSL/SAM, such as the first in situ geochronology experiment on another planet, the enrichment of atmospheric methane, and measurements of the trace heavy noble gases krypton and xenon in the Martian atmosphere.


Principal Investigator for Instrument Concepts for Europa Exploration (ICEE) sample handling system, CADMES

Solar System

Malespin is the PI for the Collaborative Acceptance and Distribution for Measuring Europan Samples (CADMES) sampling system. The CADMES system serves as a common sample delivery system for a future Europa lander, designed to simplify interface and sampling requirements on both the lander and payload. 


Dragonfly Mass Spectrometer (DraMS) Gas Processing System Lead

Solar System

Malespin is the GPS lead for the DraMS instrument on the Dragonfly mission to Titan.


DAVINCI Venus Mass Spectrometer Lead

Venus

Malespin serves as the VMS lead for the DAVINCI mission to Venus.


Sample Analysis at Mars (SAM) Testbed and Operations Lead

Mars

The SAM testbed is a duplicate of the instrument currently operating on the Mars Science Lab (MSL) rover Curiosity in Gale Crater, Mars. It is run inside a Mars chamber at GSFC which replicates the thermal and atmospheric conditions found on Mars. Charles leads the development, testing, and validation of experimental procedures using SAM testbed before use on Mars. 

Malespin is also the operations lead for the SAM instrument suite.
