Space Adventures, Ltd., the world’s leading space experiences company, announced today it has begun working with Dentsu, the world’s largest advertising agency, to send a prominent Japanese figure to the International Space Station (ISS) within the next several years.

As part of the agreement with Dentsu, Space Adventures will dedicate one of the four seats the company has available on the Russian Soyuz TMA spacecraft. Space Adventures currently has a contract with the Federal Space Agency of Russia that provides them with the sole rights to transport the next four private space explorers to the ISS. The first of the four seats has already been contracted by American technology entrepreneur, Greg Olsen, Ph.D., who is currently training at the Yuri Gargarin Training Center in Star City, Russia. His expedition is currently planned for April 2005. With two of the four seats committed, Space Adventures has two seats remaining on the Soyuz.

“I welcome the opportunity to work with Dentsu. They are the world’s premier advertising agency and we are delighted to embark on such an exciting opportunity with them,” said Eric Anderson, president and CEO of Space Adventures. “As Dentsu has cultivated unique artistic designs and opportunities for advertising in today’s marketplace, we, at Space Adventures, are using the same enthusiasm and innovative techniques to open the space frontier to private citizens. Together, we will make history by sending the first Japanese private explorer to space.”
