The three hams on the crew include mission commander Matthew Dominick, KC0TOR, making his first flight to space; pilot Michael Barratt, KD5MIJ, making his third trip to the space station; and mission specialist Jeanette Epps, KF5QNU, another first-timer. The fourth crew member named is Russian cosmonaut Alexander Grebenkin, also a mission specialist. The crew is expected to launch to the space station early next year for what is described as "a long-duration stay."
