Hello, author, Pighead In. Let's take a look at your idea.
Elevator Pitch : OK, so it's not a bad start, but it has some flaws. First of all, we don't really have informations about what the anomalous activity of the past was. I think that the Foundation has probably some data or some records of these events, even half-destroyed or half-corrupted, so maybe it would be cool to know what exactly the anomalous events were. Second of all, can you add precisions about how the satellite is sent back to the past? The Foundation have at least a Department of Temporal Abnormalities and knows how the thing work, so again, add some precisions about how they do it.
For the rest, not a bad pitch and I'm curious to see your vision of the pre-space race Foundation activity, but these flaws makes the pitch less good, simply.
Central Narrative : I just have two things to say, really quickly. First of all, these days, if your article don't have a strong narrative, it is pretty unlikely to succeed (a big shitload of SCPs have been made and after a while, you cannot do the same thing over and over). And plus, if you already have one in some logs, please, tell us! The reviewers need to know everything you had about your story in order to help you the best way possible.
Hook : Not much things to say about the hook, because… I don't feel really like it's a big hook. Like I said, temporal anomalies is something we have since a pretty long time, so as a hook, question yourself about what makes your anomaly unique, what makes it as interesting as the other temporal anomalies we have.
And that's all for me. No greenlight. The story you have is not bad at all, but all the flaws I've talked about earlier "prevent" me to totally being confident on it. Because it begins to be late, I cannot really expand further, but take already on count what I've said and don't hesitate to tell other reviewers, especially the ones at the Butterfly Squad.
For the rest, it's all for me, Pighead Out.
