NASA has invited people to send their names on a microchip aboard the Dragonfly spacecraft, which will explore Titan, Saturn’s largest moon, AnewZ reports. The mission, scheduled to reach Titan in late 2034, will study sand dunes and an impact crater in search of clues about how chemicals essential for life may form.
More than 380,000 people have submitted their names so far. Participants will receive a personalized digital boarding pass and can subscribe to mission updates. Registration for NASA’s “Journey to Titan” campaign is open until Jan. 15, 2027.
NASA plans to launch Dragonfly no earlier than July 2028. The spacecraft’s journey to Titan will take six and a half years. It will be the first rotorcraft designed to conduct scientific research on another celestial body.
NASA selected Dragonfly in 2019 and approved it as the fourth mission in its New Frontiers program. The Johns Hopkins University Applied Physics Laboratory in Maryland manages the mission and leads the spacecraft’s design and construction. Planetary scientist Elizabeth “Zibi” Turtle is the mission’s principal investigator.
Titan’s methane weather and organic-rich surface
Larger than the planet Mercury, Titan is the only moon in the solar system with a dense atmosphere. Beneath its orange haze, temperatures hover around −179°C. Water is frozen solid, while methane and ethane flow through river channels and collect in lakes and seas. Titan is the only other celestial body known to have liquid bodies on its surface.
The European Space Agency’s Huygens probe provided the first close-up view of Titan’s surface on Jan. 14, 2005. As it descended by parachute, the probe photographed features resembling drainage channels extending from bright highlands to dark lowlands. It landed among rounded stones made of water ice, in an area that may have been a dry riverbed or lakebed.
Huygens transmitted data for 72 minutes after landing. The transmission stopped when NASA’s Cassini spacecraft, which was relaying the signal to Earth, passed beyond the horizon.
Methane plays a role in Titan’s weather similar to that of water on Earth: it evaporates from the surface, forms clouds and falls as rain. Saturn takes about 29 Earth years to orbit the Sun, so each season on Titan lasts more than seven Earth years.
During Titan’s northern summer, astronomers used the James Webb Space Telescope and the Keck II telescope in Hawaii to track methane clouds over lakes and seas. A study published in May 2025 reported the first evidence that air was rising in Titan’s northern hemisphere and carrying clouds to higher altitudes.
The James Webb Space Telescope also detected a methyl radical on Titan for the first time. Sunlight or high-energy particles break methane molecules apart to create these fragments. The resulting chemical reactions can produce other compounds, including ethane.
Some of the heavy, carbon-rich substances formed in Titan’s atmosphere eventually settle on the surface. Near the equator, dark hydrocarbon particles have formed extensive sand dunes. This is one of the areas where Dragonfly is expected to land and collect its first samples.
NASA’s Eyes of the Solar System service offers a simulated view of Titan based on data and images from NASA missions.
A flying laboratory for scientific research
Unlike a conventional lander, Dragonfly will be able to fly from one area to another, allowing scientists to study a wider region. Titan’s dense atmosphere and low gravity create favorable conditions for flight.
Equipped with eight sets of rotors, the spacecraft will take off, travel several kilometers and land at new research sites. According to NASA’s current mission description, Dragonfly could visit 20 to 30 locations over more than three years and travel about 115 kilometers from its initial landing site.
Flights are planned every one or two Titan days. A day on Titan lasts about 16 Earth days.
Dragonfly will weigh about 875 kilograms and measure approximately 3.85 meters in length and width. Because little sunlight reaches Titan’s surface, the spacecraft will use a Multi-Mission Radioisotope Thermoelectric Generator, which converts heat from radioactive decay into electricity. NASA has used the same type of power source for its Curiosity and Perseverance Mars rovers.
Dragonfly will carry five scientific instruments to study Titan’s surface, atmosphere and interior. Cameras will take images during flight and on the ground, while a drill will collect samples and deliver them to a mass spectrometer for chemical analysis.
A gamma-ray and neutron spectrometer will measure the soil’s elemental composition. Atmospheric sensors will monitor local weather, while a seismometer will record vibrations that could reveal information about Titan’s interior.
Mission will study Titan’s chemistry and interior
One of the Dragonfly mission’s main scientific questions is whether the chemical building blocks of life could form on Titan. One key target is Selk crater. An ancient impact may have melted some of the moon’s ice, allowing liquid water to mix with carbon-rich material on the surface.
By comparing samples collected around the crater with those taken from nearby dunes, scientists will seek to determine what new compounds might form when water interacts with Titan’s organic-rich surface. Among the compounds of interest are amino acids, which living organisms on Earth use to make proteins.
In 2026, researchers at Purdue University used computer models to investigate chemical reactions that may have occurred in temporary ponds at Selk. They found that some amino acids could form without biological processes. Adding ammonia to the model made it possible for a wider variety of amino acids to form. Samples collected by Dragonfly could help determine whether similar reactions have taken place on Titan.
The mission may also help answer questions about the structure beneath the moon’s frozen surface. Earlier measurements by NASA’s Cassini spacecraft suggested that a large ocean might lie beneath Titan’s icy crust. However, in 2025, scientists re-examined the data and found that layers containing pockets of ice and water could better explain the observations.
Dragonfly’s seismometer may provide further evidence about these possibilities. If it detects vibrations, scientists can analyze how they travel through the moon and gain a clearer picture of what lies beneath its icy surface.
