Today at 2 p.m. ET, NASA and the Johns Hopkins Applied Physics Laboratory will broadcast a behind-the-scenes look at the Dragonfly mission, which is building what amounts to a nuclear-powered drone the size of a small car. The vehicle will explore Saturn's largest moon, Titan, when it arrives in late 2034.

The program, titled "Eye on Dragonfly Live," will be hosted by NASA's Tahira Allen and feature Zibi Turtle (APL), Melissa Trainer (NASA), and Simmie Berman (APL). The broadcast originates from APL's Building 30, where the spacecraft is being assembled and tested, and will be shown on the NASA Science YouTube channel with simulcasts across NASA social channels.

The Dragonfly team at APL delivered the nearly 13-foot-long fuselage on June 29, ahead of schedule, following a month of structural testing. "It was pretty awesome to see the lander, as we designed it, become real," said Hunter Reeling, Dragonfly thermal-mechanical integration and test lead. With structural testing complete, the team started integrating mechanical, thermal and electrical systems on July 1.
Construction of the spacecraft began on March 10, 2026. A major milestone came on June 1, when engineers announced that thermal-structural testing of the heat shield had been completed in New Mexico using Sandia National Laboratories' Solar Tower facility. The tests generated temperatures around 4,500 degrees Fahrenheit on segments of the heat shield material to simulate entry into Titan's thick atmosphere.
Dragonfly will launch on a SpaceX Falcon Heavy during a window from July 5 to July 25, 2028. NASA confirmed the mission with a total lifecycle cost of $3.35 billion.
Why Titan Matters
Titan is an unusual double-ocean world with a liquid water ocean beneath its surface and a dense atmosphere that supports a methane cycle similar to Earth's water cycle, with clouds, rain, and rivers that flow into lakes and seas. It's the only extraterrestrial body in the Solar System with abundant, complex carbon-rich chemistry and a surface dominated by water ice, making it a high-priority target for astrobiology and origin-of-life studies.
During its planned 3.3-year surface mission, Dragonfly's rotors will carry it for miles across Titan, exploring geologically interesting areas including dunes and Selk Crater. The rotorcraft can travel up to 110 miles between locations, farther than any planetary surface mission. This marks the first time NASA will fly a vehicle for science on another planetary body. The rotorcraft has eight rotors and flies like a large drone.
A Busy Stretch for Deep Space Missions
Dragonfly is part of a larger wave of ambitious NASA planetary science. Europa Clipper, launched on a Falcon Heavy in October 2024, is already in cruise phase toward Jupiter's moon Europa. The largest interplanetary spacecraft ever launched by NASA used a gravity assist from Mars in March 2025 and will use another from Earth in December 2026. The spacecraft will travel 1.8 billion miles to reach Jupiter in April 2030, then orbit Jupiter and conduct 49 close flybys of Europa.
NASA also plans to launch the Nancy Grace Roman Space Telescope in September 2026, an infrared space observatory for cosmology and exoplanet research. And the agency's Artemis program continues to build momentum. Artemis III, now scheduled for 2027, will test systems in low Earth orbit to prepare for an Artemis IV landing in 2028.
For now, the focus is on the methodical work happening in APL's clean rooms. The Dragonfly team is populating that 13-foot structure with flight electronics, wiring harnesses, and science instruments. There's still two years of integration and testing ahead before the rotorcraft leaves for Kennedy Space Center. Today's livestream offers a checkpoint on that journey.
