Did you know that scientists have been studying Mars to learn more about its deep inside? Recently, they made some exciting discoveries about the Red Planet's interior by using special waves that traveled through the planet. Let's find out what they found!
When a big rock from space, called a meteorite, hit Mars on the other side of where NASA's InSight lander is, it caused seismic waves to travel through the planet. These waves are like ripples that help scientists understand what's inside Mars. The waves showed that there is a layer of molten rock surrounding the planet's core, which is the center part of Mars. This molten layer is smaller and denser than what scientists thought before.
The core of Mars is made mostly of iron and nickel, just like a big metal ball. But it also has some lighter elements like sulfur, oxygen, carbon, and hydrogen. The researchers found that the core is smaller than they thought, with a diameter of about 3,350 km. It's like a tiny ball inside Mars!
Between the crust (the outer part of Mars) and the core, there is a rocky layer called the mantle. The mantle goes about 1,700 km below the surface. But what's interesting is that the researchers discovered a layer of molten rock, called a molten silicate layer, at the bottom of the mantle. This molten layer is about 150 km thick.
Unlike Mars, Earth does not have a molten layer around its core. Mars and Earth are different in many ways, and this is one of them. Earth is much bigger than Mars, with a diameter of about 12,755 km. Mars is only about half as big as Earth.
Thanks to the InSight mission, scientists have learned a lot about Mars and its interior. They discovered a new layer of molten rock around Mars' core and found that the core is smaller than they thought. Mars is a fascinating planet, and studying its inside helps us understand more about how planets work. Who knows what other exciting discoveries scientists will make in the future!

Hello! My name is Aoife, and I'm an 8-year-old girl from Dublin, Ireland. Today, I want to tell you about an average day in my life. But before that, let's talk about something amazing I've been learning in school - Mars! We've been studying a book called Exploring the Secrets of Mars: Unveiling the Red Planet's Deep Interior.
So, every morning, I wake up excited to go to school. After eating breakfast and getting dressed, I hop on the school bus with my friends. During our science class, we learn about Mars and its mysteries. Did you know that scientists are trying to find out what's inside the planet? They use special instruments like seismometers to study Mars' vibrations and earthquakes. It's like solving a big space puzzle!
After school, I love playing outside with my friends. Sometimes, we pretend to be astronauts exploring Mars. We wear shiny helmets and walk on imaginary red sand. It's so much fun!
In the evening, I do my homework and read more about Mars. I dream of becoming a scientist one day and exploring the secrets of the universe. Who knows, maybe I'll be the one to discover something amazing about Mars!

Attention, young explorers! We have breaking news from Mars! NASA's latest mission, Insight, has been hard at work, uncovering the secrets of the Red Planet's deep interior. In a recent TV news report, scientists revealed fascinating discoveries that will leave you in awe.
Using special tools, Insight has been able to study Mars' crust, mantle, and core. This knowledge helps scientists understand how our own planet formed billions of years ago. They have discovered that Mars' core is mostly made of iron, just like Earth's core!
But the excitement doesn't end there. Insight has also detected Marsquakes, which are like earthquakes on Earth. By studying these tremors, scientists can learn even more about the planet's interior and its history.
This mission is a giant leap forward in our understanding of Mars. Who knows what other secrets this mysterious planet holds? Keep your eyes on the stars, young explorers, for there is still so much to learn about our fascinating universe!
