On May 31, 1996 ... Up, up and away

1996 American psychonaut, Dr Timothy Leary (b. 1920) crossed over. His last words, his son Zachary said, were "Why not?" and "Yeah."  

Following his cremation, 7 grams of his ashes were launched into space. Stored in the 9-by-12-inch canister with Leary are ashes of Star Trek creator Gene Roddenberry, space physicist Gerard O'Neill, rocket scientist Krafft Ehricke and others. Together they orbit Earth every 96 minutes.

In the months before his death from inoperable prostate cancer, Leary authored a book called Design for Dying. The book was an attempt to show people a new way of viewing death and dying.
