The Galileo Seven 

The Galileo, under Spock's command, crash-lands on a hostile planet. As the Enterprise races against time to find the shuttlecraft, Spock's strictly logical leadership clashes with the fear and resentment of his crew.

A shuttle craft under Mr. Spock's command is forced to land on a hostile planet. His emotionless approach to command does not sit well with some crew members, particularly Mr. Boma who challenges Spock at every opportunity. The Enterprise and Captain Kirk meanwhile have only a short time to find the lost shuttle craft as they must deliver urgent medical supplies to Markus III in only a few days. Written by garykmcd

Did You Know?


Spock's rationale for wanting to leave a crew member behind to save others was the first instance on the series of his use of the Vulcan axiom regarding the needs of the many outweighing the needs of the few or the one. See more »


When Gaetano and Latimer first exit the shuttle, the shuttle doors open. As the doors open 3/4 of the way they stop for a second - the left side moving further than the right side - and then continue all the way open. This was due to either a problem from the hard landing, or more likely, the door movers not able to open them smoothly. See more »


Scott: What a mess.
Spock: Picturesque descriptions will not mend broken circuits, Mr. Scott.

Mixed review
11 February 2007 | by mstomasoSee all my reviews

I have mixed feelings about this episode. While its plot is a little absurd and thin, it doesn't defy scientific credibility as much as many episodes of the later series in the franchise do.

Spock's relationship with the crew and his command abilities are challenged and nicely established as he commands a shuttlecraft on what should have been a routine exploratory mission (why bring along the chief engineer and chief medical officer, we will never know). The shuttle crash-lands on a class m planet in a quasar system with all communication and sensor use completely inhibited. Giant prehistoric people in a band-level society inhabit this planet and they are not pleased by the arrival of the Galileo 7. And Kirk has an annoyed bureaucrat who is late for an appointment on board the Enterprise. There is some interesting an surprisingly well-informed anthropological discourse in this episode but unfortunately the most interesting character introduced, Crewman Boma(Don Marshall) - apparently a social scientist- is inconsistently characterized.

The plot is really a vehicle for character development in this case. It's about Spock, Spock's relationship with the crew, Spock's relationship with Kirk, and with McCoy. In some ways, a defining moment for the series. And the entire cast is up to the challenge. For me, this is the main appeal of the episode.
