June 7, 2019: It is a long distance trip. NASA announced Friday that it will open the International Space Station to private astronauts, with the first visit as early as next year. The round-trip ticket would cost an estimated $58 million. Accommodations aboard the orbiting outpost will run about $35,000 per night, for trips of up to 30 days long. The space agency says only 2 visitors per year will be allowed, for some time. Private astronauts will have to meet the same medical standards and training and certification procedures as regular crew members.
