From Greenbelt to Titan, NASA’s Dragonfly mission to seek answers on how life begins

[00:00:00]Dragonfly's a flying spacecraft headed to Saturn's moon Titan, designed to travel from place to place studying the surface. Inside a clean room at NASA's Goddard Space Flight Center in Greenbelt, Maryland, scientists covered head to toe in white suits are building and testing hardware, including a mass spectrometer which will analyze samples drilled from Titan's frozen ground.

[00:00:18]>> It's essentially a chemistry suite built into one small instrument. This is small relative to other things. Titan is packed with organic material, the ingredients for life, but it's also extremely cold, nearly 290° below zero.

[00:00:32]So, we're not a life detection mission.

[00:00:34]Instead, scientists are trying to understand what happens next, how chemistry could lead to life. Titan is like the best example that we have that we can get to of a global environment where you've got an active chemistry cycle, you have all the surface processing, and the those things that may have been the magic sauce on Earth like billions of years ago could be we could be seeing the early stages of that on on Titan or parts of that going on at Titan. It's It's the best way to learn.

[00:00:56]Dragonfly will make it into space no earlier than 2028, and once at Titan, it'll fly, land, and repeat, taking samples across miles of terrain to give scientists new clues about how life might begin. Unless we have a, you know, a little organism crawling on the camera, then obviously we'll say, "Yeah, that's life."
