During the question and answer session, the two astronauts described the difference between flying on a Space Shuttle during their last NASA missions and flying on SpaceX Dragon.

They also spoke about the long period of development between the final NASA Space Shuttle flights and Saturday’s launch, which was a 9-year journey for the pair.

The astronauts are not sure when they will be back to Earth. Their mission is open-ended, and could last between one and four months, The Associated Press reported.
