Space entrepreneur Robert Bigelow, chief of Bigelow Aerospace, has been busy marketing his private space modules, an outreach effort leading to six deals being signed with clients this year.

The deals, in the form of memorandums of understanding, involve Japan, the Netherlands, Singapore, Sweden, Australia and the United Kingdom.

"These are countries that do not want to be hostage to just what the International Space Station may or may not deliver," Bigelow reports.

Bigelow founded Bigelow Aerospace in 1999, headquartered in Las Vegas, drawing upon his construction, real estate, and hotel savvy to forge the use of expandable space structures. To date, he has spent more than $200 million to hammer out his business plan for space.
