Both, kind of..
Gene Roddenberry
On April 21, 1997, a Celestis spacecraft — carrying portions of the cremated remains of Roddenberry, of Timothy Leary and of 22 other individuals — was launched into Earth orbit aboard a Pegasus XL rocket from near the Canary Islands.[40] On May 20, 2002, the spacecraft's orbit deteriorated and it disintegrated in the atmosphere. Another flight to launch more of his ashes into deep space along with those of Majel (Barrett) Roddenberry, his widow who died in 2008, is planned for launch in 2014.[41]
James Doohan
His ashes, 1⁄4 ounce (7 grams), were scheduled the following fall for a Memorial Flight to space with 100 others, including Mercury astronaut Gordon Cooper.[28][29] Launch on the SpaceLoft XL rocket was delayed to April 28, 2007, when the rocket briefly entered outer space in a four-minute suborbital flight before parachuting to earth, as planned, with the ashes still inside.[30] The ashes were subsequently launched on a Falcon 1 rocket, on August 3, 2008, into what was intended to be a low Earth orbit, however the rocket failed two minutes after launch.[31] The rest of his ashes were scattered over Puget Sound in Washington.[32][33] On May 22, 2012, a small urn containing some of Doohan's remains in ash form was flown into space aboard the Falcon 9 rocket as part of COTS Demo Flight 2.[34]
