NASA’s Dragonfly mission to Titan will primarily use which of the following capabilities to explore Titan’s surface and study its prebiotic chemistry?
Show answer & explanation
Correct answer: A
Explanation
Solution: The correct answer is A rotorcraft lander capable of flying multiple locations to analyze surface composition.
Explanation:
☛ NASA's Dragonfly mission is designed as a drone-like rotorcraft lander (an octocopter) to explore Titan, the largest moon of Saturn.
☛ Taking advantage of Titan’s dense atmosphere (about four times denser than Earth's) and low gravity (about one-seventh of Earth's), the rotorcraft will fly from one geologic site to another through vertical takeoffs and landings.
☛ The mission primarily aims to investigate Titan's prebiotic chemistry, assess its habitability, and search for chemical biosignatures.
☛ It will sample materials and determine surface compositions across various geologic settings, including organic sand dunes and the floor of an impact crater.
Extra Exam-Relevant Facts:
☛ New Frontiers Program: Dragonfly is the fourth mission under NASA's New Frontiers program, which also includes New Horizons, Juno, and OSIRIS-REx.
☛ Huygens Probe: In 2005, the ESA's Huygens probe (part of the Cassini-Huygens mission) became the first human-made probe to land on Titan's surface.
☛ Titan's Unique Features: Titan is the only moon in the Solar System known to have a dense atmosphere (primarily nitrogen) and stable bodies of surface liquid, composed of liquid methane and ethane.
