    Dan Cremons designs and tests laser-based measurement systems for planetary science and earth science applications. Dan is currently working on a prototype spectroscopic lidar system for lunar volatiles as well as maturing a dual-fringe doppler lidar system for the monitoring of wind on bodies such as Mars or Titan. He is also interested in new lidar techniques for navigation, mapping, and landing, with an eye towards small-body landing and sample return missions. More broadly, he is interested in tracking sources and sinks of greenhouse gases on our planet as well as the habitability of other planets and satellites such as Titan, Enceladus, and Europa. He is also part of a team designing a mission to study Uranus and its satellites.

    Current Projects

    MARLI: Mars Lidar for Wind and Aerosol Measurements from Mars Orbit

    • Building and testing the breadboard Doppler system in the laboratory at GSFC.
    • Co-leading the breadboard field campaign at GGAO to measure wind from aerosol backscatterin Earth's atmosphere.
    • Developing data analysis protocols and algorithms.
    • Building and testing 2 micron Doppler lidar variant for Titan orbit (TOLA)

    Lunar Laser Ranging (LLR)

    • Co-I: Next-Generation Lunar Laser Ranging (LLR) at GSFC GGAO (PI: Erwan Mazarico)

    Titan Laser Altimeter

    • Co-I: Demonstrating Key Elements of a Titan Orbiter Laser Altimeter (PI: Xiaoli Sun)
    • Conducting a laboratory test to demonstrate the receiver sensitivity and measurement precision as a function of laser pulse energy and hence link margin.
    • Developing a preliminary instrument design, including the candidate laser transmitter, receiver telescope, candidate detector, data acquisition subsystem, mechanical layout and estimated mass and power.

    Laser Retroreflector Arrays for Commercial Lunar Landers

    • Performing thermal, vacuum, optical, and vibration testing on small laser retroreflector arrays for current and future commercial lunar landers.
    • Hardware and software engineering to support the above.
