Yes, I know there are good reasons to renew the passport before that trip, but that's not my question.
It can be used to travel to the US and arrive at a US port of entry on or before the 10th. In practice, even a recently expired US passport may be used to enter the US, but the problem may be that of getting transport to the US and/or of visited host country documentation requirement applicable to foreign persons.
