Greetings everyone- just a short question here, perhaps due to my being "kerbally informed" regarding EVAs. I know in the book it was not an issue, but in the movie they decided to add the drama of Mark bridging that final 60-70 meters on the desperate EVA gambit of breaching his suit's glove. However, the range was only 60-70 meters. Now certainly, no-one (except Kerbals) wants to go untethered into space, but I have to believe an MMU would have enough dV to reach 70m, change velocity with Watney (12 m/s), and return to the Hermes. The crew though clearly saw this as a desperate last-gasp venture. Would it have really been so difficult/perilous?
