We may never understand.
In a not so distant future, dead astronauts float through the exosphere in a zero-gravity graveyard. Perhaps they never reached their destination, or maybe they did and died on their return. What are their stories? Was their death calm and placid, or was it cold, dark and full of panic? So many more questions, like what did they see? How did they die? We can imagine hostile aliens and malfunctioning spacecraft, but we will never know for sure. The only real things to do are to pay homage and don the Analog Gather Slim Fit T-Shirt.
