Astronauts have already been to the moon.改成疑问句:Where have astronauts( )been选填
already或yet

already 与 yet 用法比较：
yet 一般放在句尾,用来谈预计要发生的事情,并且只用在疑问句和否定句中.如果我们问到期待的事情,我们说 Has it happened yet?（事情发生了吗?）如果还没有发生,我们说 Not yet.（还没有.）若已经发生,则用 already.例句：
1）He's already found his car.（他已经找到了轿车.）
2）A ：Have you found your car yet?
B ：Not yet.
3）He hasn't come back yet.
根据上述原则,应该选用 already.
