Where to begin
Actually they were transporting their wounded to a colony for treatment and then took a detour for a rescue mission and were trying the rescue Pike the rest of the episode.
But the injuries happened on an exploration mission, as far as we know.
And the Enterprise wasn't there to explore they were doing a medical check up
Splitting hairs. As I said, the Craters were exploring.
I though they were checking in on Korby since he was missing up to this point.
Hmm, I suppose so. But again, Korby's expedition was originally exploratory.
I will give you a half since the main plot was warning the people on Deneva and dealing with the egg monsters.
Umm, you're getting it mixed up with "Operation: Annihilate!" AToA was the one about Eminiar 7 and the computer war. The
Enterprise was on a formal first-contact mission to Eminiar, complete with a Federation ambassador aboard.
More like investigating a possible threat after finding all life on a known planet was wiped out.
But they were checking up on a science team on that planet. Then again, it was implied to be a known system, so yeah, I'll concede this one.
Outpost check and droping off a flag officer.
Science outpost. Again, I'm counting episodes where
anyone is doing exploration, not just the
Enterprise.
Missing ship investigation.
Conceded.
More of a follow up to make sure Horizon didn't screw up the planet and to fix if they did.
No, I call it a mission of discovery. They didn't know Iotia existed until they got the
Horizon's lightspeed transmission a century late, and then they followed up that discovery by travelling to the planet and seeing what was there. Following up on travelers' tales certainly does count as exploration, especially when they have as little information as they got from the
Horizon's signal.
Time travel by accident does not exploration make especially since the whole plot was getting home without screwing up the timeline.
You really need to brush up on your TOS episode titles. You seem to be thinking of "Tomorrow is Yesterday," which was a first-season episode and wouldn't be this far down the list. "Return to Tomorrow" was the one with Sargon, Thalassa, and Henoch taking over the crew's bodies. It had no time travel, accidental or otherwise. The
Enterprise picked up a faint transmission and investigated it, finding Sargon's planet.
Yes, but as I said, they included a planetary survey as
part of that field test. It wasn't the focus of the episode, but it was clearly something Starfleet considered central to the ship's mission.
Missing ship boy this seems to happen a lot.
This time you're off base. The
Enterprise wasn't looking for the
Exeter. They came into the Omega system to explore, and were surprised to discover the
Exeter already there. As Kirk said, "She was patrolling in this area six months ago. I hadn't heard of any trouble."
Okay lets tally this since you put the Cage in we have 55 episodes. Of those you listed 29 episodes. And of those you have 17 give or take. So basically 38 eps of not exploring.
No, it's still as many as 26 that involved
some degree of exploration, whether it was the core focus or not, and whether it was done by the
Enterprise or not.
