At the last scene when Emma listens to Matt's audio message, the lines are not correct; back in the car scene Matt says "It's really starting to rain here" and then "close your eyes and listen to this" when he opens the car window while recording the message. However, in space he says in this message "It's really coming down here" and then "listen to this", then the window is opening and then he says "close your eyes" in wrong order.
when Kwesi is praying by Sisi's grave he is reading from a tanach (hebrew bible) and not a siddur. (hebrew prayerbook). The Prayer that he said would be found in the siddur and not in the tanach.
