Dragonfly Structure Takes Shape as Parachute and Chemistry Lab Tests Advance

NASA's Dragonfly rotorcraft lander is moving through a busy stretch of hardware assembly and testing at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, with the primary structure now taking shape and key subsystems under active development at multiple sites.

The fuselage panels that form Dragonfly's body were recently delivered to APL, where engineers began assembling the structure in early April. Designed at APL and manufactured by Lockheed Martin Space in Denver, the panels use aluminum face sheets just 0.01 inches thick - far thinner than standard spacecraft construction - to meet the tight mass limits required for powered flight through Titan's nitrogen-rich atmosphere. The complete primary structure weighs just 230 pounds despite needing to survive the forces of Earth launch and Titan atmospheric entry.

Gordon Maahs, Dragonfly's mechanical systems engineer from APL, described the structure as unlike anything the team has built before - light enough for flight yet durable enough for the mission's demanding entry and landing loads. Alongside the fuselage assembly, engineers installed the mounting plate and cover for Dragonfly's multi-mission radioisotope thermoelectric generator power source, which will be loaded just before launch, and completed a fit check of the top deck that carries telecommunications components.

Vibration and static-load tests are planned for May to characterize how the structure responds to launch dynamics and the forces of Titan atmospheric entry and landing.

A full-scale parachute system test was completed on February 11 in Eloy, Arizona, marking the first trial of both the drogue and main parachutes that will decelerate Dragonfly during Titan descent. The test was led by Airborne Systems of Santa Ana, California, in coordination with NASA's Langley Research Center in Virginia and NASA's Ames Research Center in California. The test sequence was designed to replicate the descent environment Dragonfly will encounter at Titan. A second series of design-qualification parachute tests is planned for October before flight hardware construction begins.

At NASA's Goddard Space Flight Center in Greenbelt, Maryland, Dragonfly's portable chemistry laboratory - the Dragonfly Mass Spectrometer, or DraMS - is in the final stages of integration. The instrument uses two complementary techniques to analyze surface samples collected by the rotorcraft: laser desorption, which fires a laser at a sample to release molecules for analysis, and gas chromatography, which heats a sample, separates the released molecules and feeds them to a mass spectrometer for identification by mass. Together the two systems allow detection of compounds across a wide size range.

On April 15, engineers completed testing of the laser system, which was integrated into DraMS in February. Using a sample with known chemical compounds, the team confirmed that the laser and mass spectrometer can reliably identify target molecules even at very low concentrations. Installation of the gas chromatography system, provided by CNES, is underway and similar performance tests will follow. The drill system that will collect surface material and transfer it to DraMS - designated DraCO - is also in integration at Goddard, with engineers from Blue Origin's Honeybee Robotics collaborating on the work.

Dragonfly is scheduled to launch no earlier than 2028 on a six-year cruise to Saturn's largest moon Titan. Once there, the dual-quadcopter lander will spend approximately three years making repeated flights between surface sites to study Titan's chemistry, geology and atmospheric conditions, with the overarching goal of advancing understanding of the chemical processes that may underlie the origins of life.
