Mystery of the Missing ISS Tomato Finally Solved

Normally I'd respond with an annoying "RTFA!" But you're right, the article really doesn't say where the tomato was.

I sent an artificial intelligence into the Internet for me to go searching for more information. Apparently the secret has simply not yet been revealed; this article says that the astronauts on board the station said they'd found it but that they didn't publicly explain further. Presumably NASA knows.
