Yes, there is a Heaven.
The astronauts won't be able to see Heaven because it's not necessarily above the clouds. Heaven may be wayyyy above the universe where no space shuttle could reach because Heaven may be in a spiritual form.
As for deafness in Heaven, I don't think deafness exists in Heaven. I was told somewhere in the Bible that God "tests" so-called disabled or handicapped people's faith in Him. If their faith is so strong, they will be healed in name of Jesus Christ. However, Jesus Christ is not on Earth right now therefore we all will have to wait until the day we die and go to Heaven to be "healed" or "cured".
I really do not know if there will be English or other foreign languages in Heaven. Communication in Heaven MAY be based only on telepathy (speaking with our minds only).
The Bible does not necessarily specify on everything what God already knew. We will get all the answers on that day we face God and Jesus Christ.
