Science Goals & Objectives

Science Goal

To reveal the impact of small-scale ocean features on large-scale weather and climate.

Science Objective 1

Determine the degree to which 25-km resolution turbulent heat and moisture fluxes influence midlatitude storm evolution and long-term weather.

Science Objective 2

Balance the global ocean turbulent heat and moisture flux contributions to the energy and water cycles to within 5%.

Mission Concept

A passive microwave radiometer measuring from 7-175 GHz

Butterfly timeline

  • 2016

    Our Humble Beginnings

    Engineer cold emails scientist…want to meet at AGU and talk about science?

  • 2017

    Butterfly is born

    A virtual team is created, a lot of online brainstorming…what is interesting science with big societal impact?

    Earth Venture Instrument - EVI5 - internal JPL competition

    We like your science, but, you are an EVM trying to fit into an EVI, patience young skywalker….

  • 2020

    Earth Venture Mission - 3 - NASA competition

    Drinking from a firehose. Electrical or chemical spacecraft propulsion? Rigid or deployable antenna? Science Tracability Matrix whaaaa??

  • 2021

    Earth Venture Mission - 3 - NASA competition - extended COVID version

    The competition just kept going and going because of COVID…. a millon details to keep track of… so so many zoom calls…. I think most of us can remember MEV Wet Mass and Power but sometimes forget our names.
