Storyline

When John Robinson loses control of his spacewalk and falls onto a nearby planet, Dr. Smith, in command of the Robot, immediately tries to force Don and Maurine into returning to Earth rather than going after John. Thanks to some quick thinking, Smith's takeover is thwarted and the Jupiter II braces for a crash landing. Finding the planet cold but habitable, Don and the Robinsons venture out in their chariot to find John, believing they've left Dr. Smith under control. They haven't, and the scheming Doctor continues to lay plans with the robot against the Robinsons. Written by statmanjeff

More Outstanding Adventure
7 February 2015 | by See all my reviews

The Jupiter 2 crash lands on an alien planet.

Another totally outstanding episode of Lost In Space. Just a tiny drop in quality compared to the last two episodes (The Reluctant Stowaway and The Derelict) as the really big events have happened now...the ship has blasted off, it got lost in space, they all found out that Smith is a creep and they had their first encounter with space aliens.

But don't worry, there are still more things to happen...a Jupiter 2 crash landing on an alien planet and the Robot starts talking a lot more. Jonathan Harris as Smith continues to be outstanding.

More wonderful John Williams music as well.

Fans of Irwin Allen's Voyage to the Bottom of the Sea will get a thrill out of the Jupiter 2 crash as it was filmed exactly the same way as the endless flying sub footage in Voyage...in real daylight. Effects man Howard Lydecker is the man responsible for the flying sub/Jupiter 2 effects.
