Hey there, Star Gazers!

NASA's Lucy Mission is on# an epic road trip, one that will take it farther than any spacecraft of its kind has ever gone.

All# to visit a group of ancient space rocks that share an orbit with Jupiter that are called Trojans.# These Trojans might give us the details as to how our solar system began, maybe even life itself.# So, what exactly are these Trojans?

They're two huge groups of asteroids that orbit the sun along# with Jupiter.

One group ahead of the planet and one behind.

Think of them like space-time capsules# tagging along on Jupiter's orbit.

Scientists believe that these asteroids are leftovers from# the formation of our solar system over 4 billion years ago.

So studying them is like opening a# fossil record of the early solar system before planets like Earth even formed.

Enter NASA's Lucy# Mission, named after the famous Lucy fossil that helped scientists understand human evolution.

Just# like that fossil, the spacecraft could help us understand our own cosmic origins.

Lucy launched# in October 2021, beginning a 12-year journey that will take it on a grand tour of eight different# asteroids, one in the main asteroid belt between Mars and Jupiter and seven Trojans near# Jupiter's orbit.

It is an incredibly complex flight path.

Lucy will make multiple# passes near Earth to use gravity assists, which basically means it will use the planet's gravity# to slingshot itself further and faster into the solar system each time.

Also, Lucy is equipped# with ultra-precise instruments to study the shape, composition, and surface of each of the asteroids# it plans to visit.

It has high-resolution cameras to map the terrain and craters of the# asteroids; spectrometers to determine what minerals and ices the asteroids are made of; and# thermal sensors to measure surface temperatures and properties of each one.

All of this data will# help scientists piece together how these ancient bodies formed and what they might be able to tell# us about the earliest days of our solar system.

Lucy's first big target was Dinkinesh, a small# main belt asteroid that surprised everyone when Lucy flew by in 2023.

At the time, it discovered# that Dinkinesh wasn't alone.

It had a tiny moonlet orbiting it.

Then, even more surprisingly,# scientists found that the little moonlet was actually two objects stuck together.

That's# right, a binary moonlet orbiting an asteroid.

Huge surprise!

Proof that even the smallest# objects in our solar system can hold these big mysteries.

By studying these Trojans, Lucy# is helping us retrace the solar systems family tree.

We think the Trojans formed in different# parts of the solar system and then were later captured by Jupiter's gravity.

And that means# each one might be made of something different.

Some might be rocky, some might be# icy, and each could offer different clues about how planets like Earth and Mars and Jupiter# all took shape.

And just like its namesake fossil helped us understand where humanity came# from, Lucy might help us understand where our planet came from in the grand cosmic story.

Lucy's mission reminds us that space exploration isn't just about visiting new worlds.# It's about understanding our own origins.

So, next time you look up at Jupiter shining in the# night sky, remember out there a small spacecraft named Lucy is traveling millions of miles chasing# ancient asteroids to discover the secrets of how all of this began.

Thanks for watching# and as always, I'm Trace.

Keep looking up!
