It's good news for 'Lost in Space' fans as Netflix announced the return of the hit sci-fi space drama for a third and final season. The reimagination of the '60s hit series will come up with season 3 in 2021 and will follow the Robinsons in their quest to find a new home following space colonization. 

The new season will see some of those unanswered questions that season 2 posed. First, it is uncertain if Dr. Smith is dead. Viewers of the show know her to be the most resourceful of the bunch. It is likely that she could have managed to escape what seemed like inevitable death -- she has done that before. Also, it would be a bad move to kill Dr. Smith off, after all, she is one of the most interesting characters on the show. An anti-hero among all the goody-goody folks, especially the Robinson family.

Another mystery left wide open for interpretation (and will possibly be answered in season three) is where exactly have they reached. Is it Alpha Centauri at all? And if not, then how far away from their intended final destination are they? And finally, the biggest question the show will hopefully address in the next season is the reason behind Will’s weird connection with robots. 

Showrunner Zack Estrin had this to say about season 3: "From the beginning, we've always viewed this particular story of The Robinsons as a trilogy. A three-part epic family adventure with a clear beginning, middle, and end. So while this chapter of 'Lost In Space' is coming to a rousing conclusion, I’m excited about continuing to explore new stories with my friends at Netflix, and for all of the incredible possibilities that lie ahead."

'Lost in Space' stars Molly Parker, Toby Stephens, Maxwell Jenkins, Taylor Russell, Mina Sundwall, Ignacio Serricchio, and Parker Posey. Zack Estrin, Kevin Burns, Jon Jashni, Matt Sazama and Burk Sharpless all serve as executive producers on the show. 

'Lost in Space' Seasons 1 and 2 are available for streaming on Netflix.
