More detailed questions about astronauts may be addressed to the Astronaut Office, NASA Johnson Space Center, Houston, TX 77058. You may also write to specific current or retired astronauts care of the Astronaut Office.
This office does not assess or verify the authenticity of aerospace memorabilia. Googling "space collectibles" will help you find companies that do. NASA HQ Archives does not collect memorabilia, nor recommend specific companies.
The star names recognized by scientists are established through long-time usage or published by astronomers at credible scientific institutions. The International Astronomical Union, the worldwide federation of astronomical societies, accepts and uses *only* those names. Such names are *never* sold. Private groups may claim to name a star for you or a loved one, "providing the perfect gift for many occasions." However official-sounding this procedure may seem, the name and the catalog are not recognized or used by any scientific institution.
A good article on this subject is H.J.P. Arnold, “The Great Wall of China From Space: The Exploration of a Myth,” Spaceflight, Vol. 31, July 1989. In addition, the privately published book The Home Planet and several National Geographic books cover on-orbit photos.
A quick google search will show you a list of where to purchase patches. We cannot recommend private vendors. A privately published book with information about the origins of many NASA mission patches is All We Did Was Fly to the Moon, by Dick Lattimer (Whispering Eagle Press, 1985).
Persons or entities who are not NASA employees may not use of the NASA insignia logo (the blue "meatball" insignia), the retired NASA logotype (the red "worm" logo) and the NASA seal without express permission.NASA Media Guidelines
NASA Speakers Bureau must receive a request, preferably 6-8 weeks before the event. Because the Speakers Bureau is a volunteer program, we cannot guarantee that all requests will be filled. Please see NASA's How to Request a Speaker for more information.
NASA provides an online NASA Technical Reports Server (NTRS) to assist researchers in locating the kind of technical documents that you are requesting. However, due to a current review of NASA online technical materials, many previously available NASA and NACA papers, reports, and drawings are temporarily unavailable while they are reevaluated.
