Bitcoin transactions don't have timestamps. The whole point of a blockchain is to order transactions in "time". Before they are in a block, transactions are timeless.

They likely would be able to tell if any timestamps were ~16min outdated

I think you've lost my point, they do have a way of know MY transactions though. And if I happen to live on Mars, I'm fucked

You're not addressing my point though -> miners have no way of knowing which txs are Martian txs.

It could be censorship for any reason, it doesn't require some war between Mars and Earth to have your own personal txs censored. Regarding the unreasonable burden to run your own mining pool on Earth vs the mathematically improbable case that those same miners on Mars would be able to mine 4+ txs to reorg the chain and get your tx mined I think is I large and reasonable distinction to make.
