2023-2025 Internship - Dragonfly Student & Early Career Investigator Program: Dragonfly Science Planning Tool Development
Dragonfly Student & Early Career Investigator Program:
Saturn’s moon Titan is the only moon in our solar system with a dense atmosphere, which supports an Earth-like hydrological cycle of methane clouds, rain, lakes and seas. Complex organic surface materials preserve, in a deep freeze, the types of organic chemicals that were present on Earth before life developed. Titan's icy crust floats atop an interior liquid water ocean. Dragonfly is a rotorcraft lander (an octocopter) that will explore a variety of locations on Titan. Launching in 2027 and reaching Titan in 2033, Dragonfly will journey farther than any robotic lander has ever traveled. With one hop on average every other Titan day (one Titan day equals 16 Earth days), the rotorcraft will travel from its initial landing site to areas over 100 kilometers away during the planned ~3.3-year mission.
Each student investigator will work with one or more Dragonfly mission team member(s) to conduct Titan research, help formulate Dragonfly mission science and operations plans, or assist in the development of instrumentation, hardware, or testing. A cohort of up to three (3) qualified graduate students from U.S. colleges and universities is selected annually for two-year terms to work with the Dragonfly team. Students dedicate 30% of their time (concentrated during summer and academic breaks) at APL and/or their Dragonfly mentor's home institution and will receive annual funding for travel to Dragonfly team meetings and to publish and present results at a scientific conference. A faculty mentor at each student’s home institution will be granted travel support to attend the annual Dragonfly Student & Early Career Investigator Program kickoff meeting.
Dragonfly Science Planning Tool Development
DRAMPACT (Dragonfly Resource Allocation, Mission Planning, and Commanding Toolkit) is the planning tool for the Science Operations Center (SOC). Resource modeling is a key function of DRAMPACT. Given an operations plan, it simulates the data collected and energy expended during the course of the mission to ensure that we stay within Dragonfly mission constraints.
Description: Dragonfly is a severely energy-limited mission. Additionally, the power source degrades over time, further reducing the energy available. The DRAMPACT developers work with the science, instrument, and mission operations teams to plan activities which fit within energy and data volume constraints. While DRAMPACT development will continue over the course of the mission, there are a number of capabilities that have yet to be developed.
As the Guest Investigator for this project, you may…
- Work with instrument teams and mission engineers to create a library of payload activities. Payload activities are placed on the spacecraft/instrument commanding schedules for resource modeling.
- Outcome: a well-defined and extensible library of activities that will be used for planning surface operations.
- Build a GUI for science planners to interact with a Dragonfly schedule to modify and validate planned observations.
- Outcome: a robust interface for generating, modifying, and publishing science planning schedules for mission operations.
- Model when science products are downlinked based on data priority and downlink schedule.
- Outcome: For each planning cycle, a schedule of what data has been downlinked and queued for ground processing, what data remains on the lander, and when remaining data is expected to be downlinked. Flag expected data that does not arrive. This task is crucial for management of onboard storage and downlink bandwidth.
- Interface with the to-be-developed Mission Operations Center (MOC) planning tools to ensure consistent predictions for energy and data usage and downlink product schedules.
- Outcome: A rigorous comparison of two separate sets of tools (both undergoing active development) to ensure that science plans can be executed within mission constraints.
