Lost in Space

While traveling to a space colony, the Robinson family encounters an unexpected crisis that causes their ship to divert toward an uncharted planet, where they must survive through a dangerous night.

More travelers arrive on the planet after another crash, and the Robinsons work to repair their ship with the help of a new, mysterious ally.

Dr. Smith's background is gradually revealed through flashbacks that suggest a complex and enigmatic past. At the same time, the Robinsons encounter a new threat as the ship's fuel supply starts to diminish at an unexpected and concerning pace.

The Robinsons come across another group of survivors, and tensions escalate when Will takes measures to protect his family after Judy uncovers the truth about the Resolute.

The team builds a tower to transmit a signal to the Resolute while Maureen investigates a mysterious planetary phenomenon, and Will prepares to have a difficult conversation with his father.

Maureen struggles with the choice of disclosing a mysterious sky phenomenon, Don coordinates a mission to obtain fuel, and the robot's presence leads to increasing tension within the group.

As Dr. Smith pushes forward with his secret initiative, increasing seismic activity begins to destabilize the planet, compelling two teams to make urgent and challenging decisions.

Maureen comes up with a plan to address the group's fuel shortage, but carrying it out proves to be more difficult than anticipated. At the same time, Dr. Smith discovers that her secret identity is in danger of being revealed.

Judy begins searching for Maureen while Will and Penny prepare an expedition into the caves. At the same time, Dr. Smith works on a new plan for escaping the island.

As the Resolute prepares to depart the planet, the Robinson families make haste to secure their escape, while also working to distance themselves from Dr. Smith's manipulative behavior.

Seven months after crash-landing on a water-covered planet, the Robinsons attempt to restart their Jupiter mission while Will Robinson sets out to locate the missing Robot.

Penny and Maureen become trapped in a mysterious metal trench, while Don experiences the effects of a dangerous toxin.

The Robinsons anticipate a happy reunion on board the Resolute, but their optimism soon wanes as they encounter disturbing problems with the ship. At the same time, Smith uses the circumstances to advance her efforts to clear her name.

Will investigates the Robot's disappearance, while John and Judy join other survivors on the surface of a desolate planet.

As John's condition deteriorates, Judy launches a frantic international campaign to assist him, while Penny, supported by a trusted ally, remains vigilant in monitoring Smith.

Penny, Smith, and their companions are forced into close confinement as a rapidly spreading contaminant threatens their safety. At the same time, Will and Maureen join Adler in a mission to locate the Robot.

John teams up with an unexpected ally to track the origin of a mysterious audio signal detected by the ship. Meanwhile, Will grows suspicious that Adler may be withholding key information.

Maureen leads a rebellion, Hastings gives John a final warning, and Penny argues that Will's Robot has experienced a transformation.

Will and Penny work to conceal the robots and devise a plan, while Hastings intensifies his conflict with the Robinsons.

The Resolute is thrown into turmoil as the mission to rescue Scarecrow faces unforeseen complications. Judy formulates a strategy to obtain a ship for a journey to Alpha Centauri.

Judy, Penny, and Will work urgently to secure titanium necessary for their journey to Alpha Centauri, a year into their mission with the children of the Resolute.

Judy begins a search for Grant Kelly, while Penny and Will investigate a mysterious tunnel. At the same time, Maureen, John, and Don search for remnants of the SAR ship in distant space.

Scarecrow helps Maureen and John devise a plan to steal an engine. At the same time, Judy brings new passengers back to the camp, and Will discovers a surprising secret inside the alien city.

As the adults work urgently to eliminate evidence of Alpha Centauri's location, the Robinson children receive a mysterious and unsettling message from SAR.

After their ship crashes on a swampy planet, Maureen and Judy struggle to survive as they encounter a large, drooling creature. At the same time, John and Penny work to rescue the Robot, who is trapped.

Don's encounter with SAR leads the Robinsons to face a new and troubling threat, while Will endangers himself by undertaking a covert mission without any backup.

The Robinsons urgently seek help for Will, alert the other colonists, and work to activate a hidden defense system. At the same time, Vijay joins Penny on a perilous mission outside the colony.

The Robinsons and their allies make a desperate effort to bring peace and build a brighter future during the ongoing conflict over Alpha Centauri.
