I got up this morning to 23 degrees at 7am and wanted to relate to the cold on board ship and on Mars. There it never gets warm, so special neoprene padded clothing had been developed to protect and still be somewhat fashionable. Sightseers also want to make the journey. In my story, we do bring people back to Earth and the Moon after a long acclamation process.
Sorry, but no one older than 55, except for rare visits are allowed to work on the Moon and Mars, due to health reasons. The workers can only stay up to three years before they are transferred or retired, while visitors usually stay a month or when the next available shuttle returns them home. Most shuttles lift off from the Moon when our satellite is nearest to Mars. With newer propulsion, it can be as short as 39 days from the Moon to Mars.
Welcome, to my world.
