Lost in Space season 3 on Netflix: Release date, episodes and cast

Production on the series wrapped almost a full year ago in January 2021 and fans will undoubtedly be eager to find out how the space saga is going to end.

An earlier official teaser trailer showed a shot of an empty spaceship, and included Will Robinson recording what sounds like a captain's log. "If you're watching this recording, there's a chance things didn't work out the way I hoped they would."

According to the official synopsis, “the stakes are higher than ever and the Robinson family’s survival instincts will be put to the ultimate test".

It continues: “After a year of being trapped on a mysterious planet, Judy (played Taylor Russell), Penny (Mina Sundwall), Will (Maxwell Jenkins) and the Robot (Brian Steele in a robot suit) must lead the 97 young Colonists in a harrowing evacuation — but not before secrets are unearthed that will change their lives forever."

Based on the cult favourite '60s show of the same name, Lost in Space follows the Robinson family on an ill-fated mission that leaves them stranded in the far reaches of the galaxy.

What follows is a struggle for survival, as they contend against robots, fuel shortages and other life-threatening challenges, culminating in a shocking cliffhanger at the end of season two.

Lost in Space season 3 release date

Netflix has confirmed that Lost in Space season three will be released on Wednesday 1st December 2021.

The series was renewed for a third season way back in March 2020 with Netflix also confirming that the upcoming season will sadly be the Robinson family's final adventure.

Announcing the show's renewal, showrunner Zack Estrin said that the Lost in Space team had always viewed the Robinsons' story as a trilogy.

"A three-part epic family adventure with a clear beginning, middle and end," he said. "It’s also worth noting that, with what these characters go through just trying to survive each episode, if anyone deserves to catch their breath before their next mission, it’s Will, Penny, Judy, Maureen, John, Don West, Dr Smith… and The Robot. And, of course, Debbie the Chicken."

Fans of Estrin's work are in luck though – he has signed a multi-year deal with Netflix so viewers can expect to see similar content from him in the future.

Lost in Space season 3 spoilers: What will happen?

At the end of Lost in Space season two, we saw the Robinson family split up after being attacked by a group of robots. Judy Robinson is left to captain a second spaceship – Jupiter 2 – to fly the group of children safely to Alpha Centauri while the Robinson parents fight the robots with the help of their savour bot Scarecrow.

Season three looks set to resolve the fates of Maureen and John – and will follow the couple as they try to locate their children and reunite with them, in the face of "overwhelming odds".

The upcoming season will also hopefully reveal who is behind the human-made signal, which led Judy and Jupiter 2 to the Fortuna – a spaceship overseen by her biological father, Grant Kelly.

Viewers were also led to believe at the end of season two that the villainous Dr. Smith, who is actually June Harris – a petty criminal who assumed the identity of her sister to take her place on the Resolute, died whilst sacrificing herself to fight the robots. However, after her scarf is spotted aboard Jupiter 2, it seems that she did in fact survive.

The official synopsis for the season reads: "The stakes are higher than ever and the Robinson family’s survival instincts will be put to the ultimate test."

It continues: “After a year of being trapped on a mysterious planet, Judy (played by Taylor Russell), Penny (Mina Sundwall), Will (Maxwell Jenkins) and the Robot (Brian Steele in a robot suit) must lead the 97 young Colonists in a harrowing evacuation — but not before secrets are unearthed that will change their lives forever.

"Meanwhile John and Maureen — with Don at their side — must battle overwhelming odds as they try to reunite with their kids. The Robinsons will have to grapple with the emotional challenge of not just being lost — but being separated from the ones they love… as they face the greatest alien threat yet."
