A space hotel refers to a hotel built in space, where passengers can overlook the earth. At the end of April 2009, the experimental module "Founding II" of "Sun Dancer" Space Hotel completed its 10000 flights around the earth, which means that Benjello Space Company is gradually approaching the goal of establishing "Sun Dancer" Space Hotel in 20 15. In addition, according to Spanish architects, Galaxy Suite, the world's first space hotel, will be grandly opened in 20 12.
