En orbite autour de la Terre!

Kit, who works at the space center, finds a book about the universe. He decides to become an interstellar traveler. He attaches himself to a rocket and starts orbiting the Earth.

After colliding with the Hubble telescope, Kit finds himself in the middle of a cloud of space debris. He recovers several components to equip himself and manages to build a device capable of navigating in space. Before leaving for another adventure, he repairs the old Hubble.

Kit visits the Moon. He explores its craters and discovers its landscapes. But he angers a Soviet astromobile named Lunokhod. After a memorable chase, Kit manages to make peace with him and even makes a new friend.

Kit visits the Sun and almost gets burned. He moves some distance away to rest, but a flare hits him anyway. He is almost burned out when he decides to use, just in time, the power of photons to escape.

Kit is determined to discover something about Mercury. But it seems that there is nothing to discover. He goes to the North Pole where he finds, in the shadow of a crater, small ice crystals.

At first sight, Kit finds Venus to be very similar to Earth, but upon closer inspection, he begins to notice major differences. His efforts to find the inhabitants of the region lead to a volcanic eruption. He leaves immediately and understands that life on Venus is not possible.

Kit arrives on Mars. His encounter with many wild probes turns his visit into a great planetary competition. Kit is about to win when his passion for craters causes him to fail.

The asteroid belt is located between Mars and Jupiter, and Kit has a hard time getting through it. He requests the services of Ceres, the largest dwarf planet in the belt, but cannot afford the trip. He then returns where he was.

Kit hears a strange signal that leads him to a sleeping comet. On its frozen surface, he meets two icy probes : Philae and Rosetta. He uses his energy to wake them up but lacks electricity to leave.

Jupiter tries to stop Kit from getting close. He finds himself in the atmosphere and realizes that there is nowhere else to land. He gathers all his forces and succeeds in approaching Jupiter but the planet does everything to move away from him.

Kit finds himself injured and dirty after falling on the moon of Jupiter: Ganymede. Unable to fly, he is then used as a baseball in the game between the moons. On Europa, he manages to clean himself with a geyser of ice water and finally leaves the game.

Saturn's moons race around the rings. Kit can't resist and joins the event. But he causes an accident and damages the beautiful rings of Saturn.

Kit is sad to be so far from home, he stops on the Miranda moon to rest. He falls asleep and dreams of his friends but his dream soon turns into a nightmare.

Kit has trouble recharging his batteries being so far from the Sun, and it is at this very moment that he is captured by Neptune. As he doesn't want to be stuck like Triton, he tries to escape. He fights against Neptune and uses his anger to escape
