NASA Face in Space: "NASA wants to put a picture of you on one of the two remaining space shuttle missions and launch it into orbit. To launch your face into space and become a part of history, just follow these steps:
First...Select the Participate button at the bottom of this page and upload your image/name, which will be flown aboard the space shuttle. Don't have a picture to upload? No problem, just skip the image upload and we will fly your name only on your selected mission!
Next...Print and save the confirmation page with your flight information.
Later...Return to this site after the landing to print your Flight Certificate - a commemorative certificate signed by the Mission Commander. You can also check on mission status, view mission photographs, link to various NASA educational resources and follow the commander and crew on Twitter or Facebook."
