Aboard were commander Reid Wiseman, pilot Victor Glover, mission specialists Christina Koch and Jeremy Hansen of the Canadian Space Agency. From launch on April 1 to splashdown off San Diego on April 10, the flight lasted <strong>9 days, 1 hour and 32 minutes</strong> — the time the four spent outside the umbrella of Earth&rsquo;s magnetic field.</p>
