NASA Plans Drone Mission to Titan, Saturn's Largest Moon

U.S. space agency NASA said Thursday its new mission would explore Titan, Saturn's largest moon, using a drone lander called Dragonfly.


The crewless craft with four propellers is slated to launch in 2026 and reach its destination in 2034.

"What really excites me about this mission is that Titan has all the ingredients needed for life," said Lori Glaze, director of NASA's planetary science division.

What Will the Mission Involve?


The nuclear-powered Dragonfly is expected to spend two years flying vast distances across Titan's surface and touching down at different sites of interest.

It will visit the icy moon's dunes and the floor of a crater to search for signs of past or present microbial life. Its instruments will also investigate the atmosphere and an underground ocean.

"Visiting this mysterious ocean world could revolutionize what we know about life in the universe," NASA administrator Jim Bridenstine said. "Titan is unlike any other place in our solar system, and the most comparable to early Earth."

This similarity to our own planet means Saturn's moon could potentially hold clues for researchers about the origins of life.

What Do We Know About Titan?


Based on images collected by a previous mission, Titan has a rocky, rugged landscape, with lakes made of methane and ethane. It also has an ocean below its crust. It is the only place, besides Earth, known to have liquid rivers, lakes and seas.

Of the more than 150 known moons in the solar system, Titan is the second-largest, and the only one with a thick, hazy atmosphere. Like Earth, its atmosphere is nitrogen-based. But unlike Earth, Titan has clouds and rain of methane.

The European Space Agency's Cassini-Huygens probe became the first spacecraft to land on Titan in 2005. That mission measured the temperature, pressure and density of the atmosphere and took pictures of the moon's surface.

The newly announced Dragonfly mission will be developed and led by Johns Hopkins University's Applied Physics Laboratory in the U.S. state of Maryland.

My name is Arkilaus Kladit. I'm from the Knasaimos-Tehit tribe in South Sorong Regency, West Papua Province, Indonesia. For decades my tribe has been fighting to protect our forests from outsiders who want to log it or clear it for palm oil. For my people, the forest is our mother and our best friend. Everything we need to survive comes from the forest: food, medicines, building materials, and there are many sacred sites in the forest.

Overthinkers are people who are buried in their own obsessive thoughts. Imagine being in a large maze where each turn leads into an even deeper and knottier tangle of catastrophic, distressing events — that is what it feels like to them when they think about the issues that confront them.

A 4,000-year-old ice shelf in the Canadian Arctic has collapsed into the sea, leaving Canada without any fully intact ice shelves, Reuters reported. The Milne Ice Shelf lost more than 40 percent of its area in just two days at the end of July, said researchers who monitored its collapse.

The coronavirus cases surging around the U.S. are often carried by kids, raising fears that the reopening of schools will be delayed and calling into question the wisdom of school districts that have reopened already.
