The New Genesis Saga - Book 5: The Lost Ark.

Book 5: The Lost Ark

After new long-range satellites are deployed into space, the people of Eden Colony are surprised to learn they have come in contact with another Ark ship from Earth. When they lose contact abruptly, the decision is made to send up a rescue team to search for any possible survivors.

Of course, I will have to toss in an homage to Indiana Jones in this book.
