Mars is infested with robots, orbiting the planet and roaming the Martian surface on a mission to uncover its secrets; now, Perseverance joins this dedicated group of machines to uncover if there is, or was ever, life on the Red Planet.
Our neighbor, Mars, fascinates us. It's a planet that is similar to Earth but with some big differences. Mars is rusty, dusty, frigid, and frozen. Past missions suggest that Mars was once a very different world. The Mars we see today has completely changed from the Mars of a few billion years ago. Without a time machine to explore ancient Mars, we employ a team of high-tech robot investigators, an entire fleet of robotic spacecraft exploring the planet. Working together, they dig into Mars's past to answer the ultimate question -- did Mars once have life?

The magnificent ringed planet Saturn, along with its more than 80 moons, forms the most dynamic planetary system in our neighborhood. With underground oceans and protective magnetic fields, experts are exploring how this collective of satellites has the potential to rewrite the rules of the Solar System.
The closer that we look, the more we see these extraordinary moons like worlds of their own -- so dynamic, so Earth-like. Almost a billion miles from the Sun, these icy worlds could be home for Life 2.0. The moons of Saturn offer possibly the best chance of finding extraterrestrial life in our solar system. With each new mission, we get closer to unraveling the mysteries of Saturn's moons.

All of our pets survived for thousands of years in the wild without any help from us, and this has led them to develop astonishing athletic abilities which we sometimes take for granted. As greyster dogs and endurance champ tortoises.
Dog scootering uses one or more dogs to pull a human riding an unmotorized scooter. Greysters are a naturally-athletic breed that can run at 20 miles per hour for five miles while handling these carriages. No other animal can run at this speed, exerting this power, and expending this energy for so long. So, what's their secret? Greysters' stride length can be a staggering 16 feet and they are super efficient at absorbing and using oxygen. Greyster dogs have nearly twice mitochondria inside their cells than humans.

Our super friends in the animal world possess so many hidden superpowers. In the third episode we meet heat-seeking dogs, GPS-outfitted cats, and a sporty goldfish with squad goals.
When we think we know them inside out, dogs surprise us with something new. what sensory superpower have dogs been hiding all this time? They have a thermal sensor in the tip of his nose. In the wild, a dog could use his thermal nose to spot the heat of a prey animal, allowing him to hunt even if his other senses were impaired. It also explains that uncanny knack for stealing a warm seat.

What If we could talk to animals? For as long as we've shared our lives with pets, we've been seeking better ways to communicate with them. In Washington state, Alexis Devine and her sheepadoodle Bunny think they've found a way of making communication a reality. Alexis went further than most, with a set of communication buttons, each programmed with a pre-recorded word to help humans and animals speak the same language. She has 90 buttons with which to express herself and even seems to combine them into simple sentences. Bunny is paving the way in pet communication.
The undisputed masters of verbal communication are our pet parrots. They have mastered the art of vocal expression. Some parrots have even learned to fool devices designed to recognize human voices.

In households across the world, pets are at the heart of family life. They share our homes, but how well do we really know them? In this series we'll dig deep into our pets' inner lives to discover the secrets they've kept hidden until now. From spectacular feats of communication to extreme athleticism, extraordinary intelligence and incredible super senses.
We'll meet remarkable pets from across the globe whose owners have harnessed their hidden skills and shared them with the world and will use groundbreaking technology to reveal how amazing their brains and bodies really are.
In the first episode, a base-jumping border collie, a bopping cockatoo, and racing rats show that animal intelligence can get a big boost in the right enriched environment.
