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?


Although the Galileo was destroyed in this episode, it appeared again in four later episodes, Star Trek: Journey to Babel (1967), Star Trek: Let That Be Your Last Battlefield (1969), Star Trek: Metamorphosis (1967), and Star Trek: The Way to Eden (1969). However, it wasn't until its final appearance that the full-scale ship was repainted to read Galileo II. See more »


When the spears strike the rocky landscape, its real nature can be seen. One spear strike causes it to wobble, and another cuts the landscape, causing some of the stuffing to come out of the set. See more »


Scott: [checking the shuttle's damage] Very bad, Mr. Spock.
Spock: In what way?
Scott: We've lost a great deal of fuel. We have no chance at all to reach escape velocity. And if we ever hope to make orbit, we'll have to lighten our load by at least 500 pounds.
Spock: The weight of three grown men.

Good Character Development
10 November 2015 | by See all my reviews

Star Trek was hitting its stride by the time of the "Galileo Seven". The title might actually be a variation of "Twelve Angry Men" another story of several interesting characters forced into a situation where important choices need to be made. The characters of Spock, McCoy and Scott in particular are advanced here as we learn more about each of them. Spock's strictly logical thinking proves to be both an advantage and a detriment as he is the ranking officer and responsible for the ultimate choices being made here. McCoy on the other hand acts as Spock's "human" conscience, figuratively sitting on his shoulder and pushing him not to rely so much on his non-emotive Vulcan side. Scott merely does what he does best by tirelessly testing theories using the resources he's provided to do his part in solving the problem at hand. In this case, the shuttlecraft "Galileo" is stranded on a hostile planet with large alien creatures determined to prevent their escape. The conclusion will surprise you and ultimately gives some great insight into the character of Spock.
