NASA is planning to ship a drone to a close-by moon that can hunt for alien life.
The Dragonfly probe will discover Titan, Saturn’s largest moon – round 745 million miles from Earth.
That may sound like an enormous distance, however it’s a stone’s throw in house phrases.
The launch is ready to happen in July 2028, with the Dragonfly rotorcraft reaching Titan in 2034.
Nasa first introduced the mission again in 2019, and we’re now just below 4 years away from the complete launch.
“With the Dragonfly mission, NASA will as soon as once more do what nobody else can do,” stated then-NASA Administrator Jim Bridenstine, talking on the time.
“Visiting this mysterious ocean world might revolutionize what we learn about life within the universe.
“This cutting-edge mission would have been unthinkable even only a few years in the past, however we’re now prepared for Dragonfly’s superb flight.”
Titan is a huge moon – the second largest in our photo voltaic system, and even bigger than the planet Mercury.
Nasa says it has a nitrogen-based ambiance like Earth – however its clouds and rain are methane.
And its floor temperature is a staggeringly low -179C / -290F.
To assist Nasa’s Dragonfly survive on Titan, the house company has used Cassini information to decide on a interval of calm climate for touchdown.
It’s going to start its exploration at dune fields alongside the equator, which Nasa says are like those in Namibia.
Initially Dragonfly will discover in brief flights.
However this can ultimately develop to longer five-mile flights, throughout which it can acquire samples.
Its final vacation spot is the Selk impression crater, the place Nasa hopes to search out proof of previous – and even residing – alien life.
SATURN’S MOON TITAN EXPLAINED
Here is what it’s essential know…
“The lander will ultimately fly greater than 108 miles (175 kilometers) – almost double the space traveled thus far by all of the Mars rovers mixed,” Nasa stated.
Nasa says that the Dragonfly will launch “no sooner than July 2028”, after reaching closing approval for the mission in April this yr.
It will price round $3.35 billion (£2.6 billion) over its full lifecycle – roughly double the proposed invoice from 2019.
“Dragonfly is a spectacular science mission with broad group curiosity, and we’re excited to take the subsequent steps on this mission,” stated Nasa’s Nicky Fox, affiliate administrator of the Science Mission Directorate.
Dragonfly marks the primary time Nasa will fly a automobile for science on one other planetary physique.

“Exploring Titan will push the boundaries of what we will do with rotorcraft exterior of Earth.”
The craft itself is being inbuilt Laurel, Maryland, on the Johns Hopkins Utilized Physics Laboratory.
It is going to be a breakthrough mission that makes house historical past.
Nasa explains: “The rotorcraft, focused to reach at Titan in 2034, will fly to dozens of promising places on the moon, searching for prebiotic chemical processes frequent on each Titan and the early Earth earlier than life developed.
“Dragonfly marks the primary time Nasa will fly a automobile for science on one other planetary physique. The rotorcraft has eight rotors and flies like a big drone.”
Titan has low gravity, a dense ambiance, and low ranges of wind, which ought to make it comparatively simple for Dragonfly to fly.
The craft is anticipated to weigh round 990lb (450 kilos), and will likely be packed inside a 12-foot heatshield.
Throughout Titan nights – which final round 192 hours – Dragonfly will stay on the bottom.
And through days, it is going to be in a position to acquire priceless information and samples.
That features from the 56-mile-wide Selk impression crater, looking for proof of alien life – and doubtlessly altering science ceaselessly.
