Space Travel: (Noun) Travel through outer space.

Star Trek creator Gene Roddenberry and his wife Majel Barrett Roddenberry are going boldly where no cremated remains have gone before: outer space! Wait, "going boldly" is a Star Trek thing, right? How the hell should I know? Do I look like a nerd to you? Anyway:

The couple's cremated remains will be sealed into specially made capsules designed to withstand the rigors of space travel. A rocket-launched spacecraft will carry the capsules, along with digitized tributes from fans. The Roddenberrys' remains _ and the spacecraft _ will travel ever deeper into space and will not return to earth, company spokeswoman Susan Schonfeld said. (Source)

Most people probably think that sounds eccentric, but I don't think there's anything wrong with wanting your final resting place to coincide with your life's passion. I personally plan to have my cremated remains used to make a nice, oak-aged chardonnay which all of my friends and family will then be forced to drink at my funeral. Hey, it's still way less creepy than LifeGems®.
