DRAGONfly is an autonomous glider designed to deliver a data vault from high altitude weather balloons to ground stations. This vehicle was designed for the NASA Balloon Program Office as a part of the FLOATing DRAGON (Formulate, Lift, Observe, and Testing: Data Recovery and Guided On-Board Node) competition beginning in August 2022. After submitting a conceptual design in January 2023, the DRAGONfly was selected as one of the six finalist vehicles to be built for a test flight in August 2023. This flight was cancelled by the FAA due to safety concerns of dropping student projects from 120,000 ft over populated areas. To circumvent the FAA, NASA proposed a second challenge and allowed teams to create a new prototype to drop in Antarctica where there would be no FAA, nor the risk of hitting landing in a populated area.

The team was selected as one of the six finalist teams on January 30th, 2023.
July 14, 2023 - Video Conference
A month before flight, the software design review was held over a video call with NASA. The Dragonfly team presented test cases using sample sounding files to prove the control systems and waypoint planning algorithm would be successful.
August 11, 2023 - Fort Sumner, NM
Four team members traveled to Ft. Sumner, NM with the Dragonfly to complete final tests with the BPO and integrating the deployment system into the NASA gondola.
August 19, 2023 - Fort Sumner, NM
Although the FAA denied the nodes to be dropped, NASA allowed for the nodes to be carried with the gondola as planned. The flight, which the BPO referred to as the Salter Test Flight, landed 122 Nm southwest of the launch site.
More information about the test flight can be found here.
November 6, 2023 - West Lafayette, IN
Purdue Dragonfly team submits notice of intent to participate in the ICE-DRAGON challenge. Teams from Notre Dame, Princeton, and UT Austin also submit notice of intents.
January 9, 2024 - West Lafayette, IN
With the beginning of the Spring 2024 semester, a new team was formed to create the second Dragonfly vehicle. Work began on the design, analysis, and manufacturing of the vehicle in the second week of the semester.
April 2024 - Zoom Call
The Purdue Dragonfly team presented a concept of operations for the Dragonfly V2 vehicle to NASA and were approved to move forwards.
June 2024 - Zoom Call
The Purdue Dragonfly team presented the manufacturing progress and modes of failure for the Dragonfly V2 vehicle to NASA and were approved to move forwards with integration.
June 24, 2024 - Palestine, TX
The team travelled to Palestine, TX to perform a drop test and integrate the Dragonfly into the NASA gondola system. The drop test was passed and the vehicle was passed to NASA to bring to Antarctica.
December 2024 - Antarctica
In Antarctica, a deployment actuator failed and a control surface came loose from its torque rod. The vehicle was not able to be repaired before the SALTER mission launch on Dec 22nd, 2024.
