This Spoils the Ending
In the Book In the Movie
   The Hail Mary is damaged while sampling the Adrian atmosphere. Grace is injured and trapped under some equipment. Rocky leaves his enclosed area to rescue Grace. Rocky’s body ignites in the oxygen rich atmosphere of the Hail Mary. Grade manages to return an unconscious Rocky to his enclosure and is injured by the ammonia gas in the process. The ship’s robot arms treat him for inhaling the ammonia gas. Rocky saves Grace when the Hail Mary is damaged, but is able to make it back to his enclosure by himself.
   While high on pain killers due to his injuries, Grace puts the Adrian sample apparatus into a container that has no way to opening it without exposing it to the ship’s atmosphere. Rocky makes a device that will extract the samples safely, but only after Grace goes a period of time without pain medication. Rocky repeatedly asks Grace if he is using oxygen gas during the extraction; Grace gets mad when he is bothered by Rocky. Rocky is afraid of oxygen since he burst into flames while rescuing Grace. This does not happen in the film.
   The Taumoeba escape the sample containers and consume the Hail Mary’s fuel supply. Rocky and Grace mount the Beetles to the hull exterior to power the Hail Mary and return it to orbit around Adrian. This does not happen in the film.
   There is much about Grace training Shapiro and Dubios for their science duties on the Hail Mary. Shapiro and Dubois are also having an affair which they discuss in front of Grace; this makes him uncomfortable. This is not in the film although Dubios and Shaprio are shown sitting next to each other in the lounge on the aircraft carrier. Both of their characters are more like glorified extras in the cast with very few words spoken.
   Grace is very busy developing equipment and procedures for the lab on the Hail Mary. This is not in the film.
