I don't think it's not feasible. For example they can use a script generating a random seed without displaying it, but giving an address belonging to this seed allowing to send funds to it.
The script will then write the seed in a file and/or print it on a small sheet of paper once the rocket has reached the moon or a giving date has pasted.

but that's the problem though. the private key has to be engraved onto the rocket. that has to be done before it launches. someone is going to be able to see it. because it has to be on a computer before it can be engraved by a computer. not only that but someone could sneak inside the spaceship before it launches and take a peak at the private key.
In any way..... nobody will fund a project to search for those bitcoins now, because that is roughly worth about $1 800 000 now.... but if the price really goes to the Moon.. we might have a new Lazlo event, where those bitcoins might end up being a few hundred million dollars.
