Episode list

The four children Mie, Elias, Noor and Johannes start a two-week science course at an AstroCamp, led by the enthusiastic Bolette-Henriette and the slightly distracted Panda-Søren. The four children end up in a group together, but on an intro run they get lost in a basement in the research department, where access is otherwise forbidden for students. Here they find a mysterious machine that accidentally makes Mie and Johannes disappear.

Noor and Elias try to keep it a secret that Mie and Johannes have disappeared, but Panda-Søren and the researcher, Anna, find out. The four decide to keep it a little secret while Anna tries to find a solution. On Planet 9, Mie and Johannes try to find out what happened to them. While chasing a sound that, they hope, can lead to help, they must at the same time relate to the fact that they have become seven years older.

Noor and Elias help Anna solve the mystery and return to the machine to find clues. As they piece their knowledge together, they find out that Mie and Johannes are stranded on Planet 9, which they have otherwise never heard of. Johannes and Mie finally find the source of the sound that they have pursued, and it is a very big surprise for them when they meet the hairy creatures, the 9s. The 9s can explain that they are on Planet 9, which makes John's sweat especially on his forehead.

It dawns on Noor and Elias that Mie does not have her insulin with her, and they therefore have to go to Elias and Mie's home to get an insulin pen. Here they meet resistance from little sister Mathilde, who nevertheless gives them the decisive help. Mie and Johannes meet the bitter and brusque Mette, who has been stranded on Planet9 for ten years. To their frustration, however, Mette can not help them home, and the situation worsens as Mie gets worse and worse due to her diabetes and lack of insulin.

Noor and Elias visit FlyCorp to get them to turn on the machine again so they can send Mie's insulin pen away. The charismatic owner, Viggo V, is very kind to them, but it turns out he has a hidden agenda. Johannes and Mie have some material from Earth that Mette is trying to use to repair the return machine. Mie's health worsens to John's great concern as they hopefully wait for the insulin pen from Earth.

Noor, Elias and Anna find out why Viggo V is so interested in the machine and Planet 9. Viggo, however, wants to destroy the machine, but instead damages the age calibrator. Johannes, Mie and Mette try once again to fix the return machine, and to their great joy they succeed in sending a stone as a test. But since they have to test something live, it does not end quite as planned. Panda-Søren is very worried about the consequences if Mie and Johannes do not come home soon.

The pressure is increasing on Noor and Elias to prevent Viggo from getting the machine, while at the same time having to take care of the egg and prepare for a big presentation. The conflict between Mie, Johannes and Mette escalates as they can not agree on what to say to the 9s about Tanja. Mie and Johannes quarrel, and Mie goes out on the misty planetary surface to look for the 9s and tell them the truth. Johannes gets frustrated and injured back in the cave with Mette.

Noor and Elias disagree on whether to spend the time looking for the missing 9ser or making their presentation so Bolette-Henriette does not discover that Mie and Johannes are gone. Johannes is about to go to worry about Mie, but Mette persuades him not to go out into the dangerous fog and look for her. At the same time, it's not quite as easy for Mie to find the 9s on the planet's surface as she thought.

Noor and Elias no longer dare to have Little Tanja living at AstroCampen. They try to keep her hidden, but it's hard as Bolette-Henriette has invited the energetic YouTuber, Buster Båster, to attend the class. Buster thinks that there is a Santa monster at stake, and he chases the sensation. Johannes is worried about Mie, who is still out looking for the 9s.

Tom addresses Noor and Elias on behalf of Viggo V and comes up with a tempting offer, but they reject him. To help Anna, Noor and Elias instead break into the Niels Bohr Institute to find a crucial component, but it's not easy. Mie, Johannes and Mette are trapped in the root cage and cannot agree on choosing someone to take the punishment. The confinement causes Mie and Johannes to open up to each other.

Elias sacrifices himself and takes responsibility for the fad at the Niels Bohr Institute, so he is thrown home while Noor can stay. Noor helps Anna with the age calibrator, and at home Elias has to help Mathilde save Little Tanja for their mother, Kirsten. A frightened Johannes is led by the 9s to a special cave, where he has to help the 9s with a specific task. Meanwhile, Mie is very worried about what has happened to Johannes.

In the best belief that the age calibrator can be fixed, Noor tries to get help in an unexpected place. However, it backfires, and she has to crawl to confess to Elias, who is still expelled and has her own problems with Little Tanja and Mathilde. Mie and Johannes are still trapped in the cage with Mette, who is very preoccupied with the lump of magilium that Johannes had with him back. They learn why, Mette is on Planet9.

Elias is still disappointed with Noor, who regrets that she tried to get help from someone they could not trust. It does not get any better when he finds out that she has received a FlyPhone as a thank you. At the same time, Bolette-Henriette has her own plan for solving the problems and turns to Viggo V. for help. On Planet 9, Mie and Johannes must return to the crystal cave to collect magilium from the well, while Mette tries to distract the 9s by the machine.

The day has come when the course at AstroCampen officially ends. Noor, Elias, Panda-Søren and Bolette-Henriette must therefore jointly convince the parents that Team Kometerne has been selected to stay on the course one more week, so that they can get Mie and Johannes home in the meantime. Mie and Johannes fight to collect magilium so they can send it home to Earth, while Mette tries her best to keep the 9s.

Elias and Noor are now the only children left at AstroCampen, and they have got a slightly unrealistic idea of how to get Mie and Johannes home. For once, Bolette-Henriette has a better plan, which, however, involves Panda-Søren, who is not fully involved in it. Mie, Johannes and Mette dream of returning to Earth, but to their great frustration, Viggo has not fully kept his promise. At the same time, a mysterious fog is spreading in the corridors, and they are surprised that they do not see anything until the 9s.

Anna has finally finished the age calibrator, so now Tanja can return to Planet 9, and Mie, Johannes and Mette can return home to Earth. But when Viggo V discovers that there is an alien on Earth, he lays out a new and sinister plan involving Tanja. Mie and Johannes are in doubt whether they will like each other as 12-year-olds and are considering staying 19. At the same time, Anna is involved in Viggo V's new plans for Planet 9.

Mie and Johannes have made a choice that creates completely new challenges for themselves, Elias and Noor. Mette tries to prevent Anna from going to Planet 9.

Anna has returned home from Planet 9 with gruesome video footage, and Kirsten is losing patience. In the cabin, Mie and Johannes are challenged.

Elias and Noor are completely discouraged because they have no idea where Mie and Johannes are. To save Planet 9, the plan requires them to sneak into Flycorp.

Anna and the kids are still trapped in a small room and the oxygen is about to run out. Viggo welcomes the good sales of FlyPhones, but gets a nasty surprise.

Mie, Johannes, Elias and Noor must find their way to the Magilium Cave, but the mission is threatened. Today, AstroCamp ends and parents arrive to pick up their children.

The children meet the 9s, who are debilitated and frustrated. At the same time, the practical preparations for entering FlyCorp and turning on the machine are in full swing.

The children solve the mystery of the many Viggos, but the real Viggo V has Tanja hostage. Anna, Bolette-Henriette and Panda-Søren sneak into FlyCorp.

Johannes, Noor and Mie try to get in touch with Elias and get help from an unexpected edge. Viggo V. has lost his way on Planet 9 and discovers that he has been cheated.
