Long answer: at their closest earth and mars are about 54m km apart, at the furthest it's over 400, with an average of around 225m km, so theoretical latency is varies between 4 and 24 minutes.
CockroachDB uses synchronous replication via raft, and that latency would cause problems as would some other setting like our window sizes and their interaction with timeouts.

Deep space aside, I wish the announcement just said that! I came back to HN for insight into the paragraph about "multi-active availability... an evolution in high availability from active-active replication". Marketing... sometimes... I tell you what.
