The term "Dragon 2 DragonFly" is not an established, widely recognized concept in aerospace or scientific literature. It appears to combine two distinct projects or concepts associated with SpaceX: "Dragon 2" and "DragonFly."
Definition "Dragon 2 DragonFly" is not a defined or recognized entity. Instead, it seems to be a conflation or hypothetical combination of SpaceX's Dragon 2 spacecraft and an early propulsive landing test concept known as DragonFly.
Overview Given that "Dragon 2 DragonFly" is not an established concept, it is necessary to discuss its constituent parts separately to provide context.
- Dragon 2: This refers to the second generation of Dragon spacecraft developed by SpaceX. It encompasses both the Crew Dragon, designed to transport astronauts to and from the International Space Station (ISS), and the Cargo Dragon 2 (or Dragon XL), an uncrewed variant for resupplying the ISS. Dragon 2 vehicles are distinguished by their reusability, updated avionics, and redesigned pressure vessels compared to the original Dragon (Dragon 1) cargo spacecraft. Crew Dragon is human-rated and features a launch abort system using SuperDraco engines.
- DragonFly: This was an early propulsive landing test vehicle concept developed by SpaceX. It was based on a modified Dragon capsule and was intended to demonstrate vertical take-off and landing capabilities, simulating aspects of a Mars landing. Tests for the DragonFly program were conducted at SpaceX's McGregor, Texas facility around 2013-2015. The project aimed to mature technology for precision propulsive landings, which was seen as critical for future Mars missions, including the Red Dragon concept (later cancelled in favor of Starship development).
Etymology/Origin The origin of the combined term "Dragon 2 DragonFly" is unclear, as it is not an official designation from SpaceX or a commonly used term within the space industry. It likely stems from associating the current Dragon 2 spacecraft with the earlier DragonFly propulsive landing test program, possibly to speculate about a hypothetical Dragon 2 variant that might incorporate or evolve from the DragonFly testing.
Characteristics Since "Dragon 2 DragonFly" is not a recognized concept, it does not possess defined characteristics.
- Dragon 2 characteristics include: orbital maneuvering, cargo and/or crew transport capability, reusability, SuperDraco abort engines (Crew Dragon), and automated docking.
- DragonFly characteristics (as a testbed) included: a modified Dragon capsule structure, four SuperDraco engines, and avionics for autonomous propulsive flight and landing tests within Earth's atmosphere.
