DEAD ASTRONAUTS

Traveling a hundred times as fast as Apollo, the nearest star is a millennium away. What if aliens from there tried to come here? A lot can go wrong in a thousand years. An interstellar probe decelerates into earth orbit. Nothing happens. An astronaut team discovers why. Its crew died in transit. Exposed to whatever killed the aliens, can NASA let the explorers come home? Quarantined and running out of air, how can they survive?_,
