ckers. Two designs state simply "I Voted Today," with the state motto in smaller type. Other options range from the straightforward "I'm a Buckeye Voter" to a play on the state name, "O-H I vOte." But the prospect of offering all voters, regardless of their religious beliefs, a sticker with the word "God" isn't sitting well with some voting rights activists. "The ones that have the state motto on it would kind of put atheists in a bind, wouldn't it?" Ellis Jacobs, senior attorney for Advocates for Basic Legal Equality, told the Middletown Journal. "There are a heck of a lot of atheists out there. They shouldn't be made uncomfortable when they go to vote." Catherine Turcer of the government watchdog group Ohio Citizen Action argued that people of all religious persuasions should feel welcome when voting. "People love their stickers," Turcer told the Middletown Journal. "It's like a badge of honor. So the badge of honor should not be contentious." About 2,000 people have voted in the online contest to determine the design of the new sticker, partly aimed at encouraging more young people to vote. Matt McClellan, a Husteed for future spacecraft. Endeavour is due back on Earth early Wednesday. It will be retired to a California museum after this 16-day journey, its last. Kelly got a special musical send-off late Sunday night from his wife, Rep. Gabrielle Giffords. She's recuperating in Houston from a gunshot wound to the head. The wakeup call was a song by a Tucson, Ariz., band. Kelly said the song, "Slowness" by Calexico, is about two people reaching across a distance, and references places in Tucson, the congresswoman's hometown. "I know she really, really wants to get back there," he radioed. "It's an appropriate song because that's coming soon." The two space crews said their goodbyes earlier in the day, right before the hatches closed between them. Kelly was the last to leave the space station, lingering for a few seconds with the three space station residents. "We're looking forward to getting home," Kelly said, "and we're going to leave these guys to some peace and quiet and not disturb their space station any more." The station's skipper, Russian Andrey Borisenko, wished the six shuttle astronauts a "soft landing." Endeavour will return to Florida in the pre-dawn hours of Wednesday, never to fly in space again. On its final journey, Endeavour delivered a $2 billion cosmic ray detector that will remain on the space station for the next decade. The Alpha Magnetic Spectrometer already is collecting 25 million to 40 million cosmic particles a day worthy of analysis. It's searching for antimatter and dark matter, and scientists hope the findings will shed light on the origin of the universe. Kelly and his crew also provided the space station with a platform full of spare parts and an extension boom for future repair work. The boom, installed Friday on the fourth spacewalk of the mission, marked the completion of the U.S. portion of the space station. The astronauts also worked on some of the critical life-support systems inside, in an effort to leave the orbiting outpost in the best possible shape for the shuttle-less years ahead. Astronauts Mike Fincke and Gregory Chamitoff -- who spent months living on the space station in years past -- pretended they didn't want to leave Sunday morning. They were dragged into the shuttle by their crewmates. Garan joined in on the joke, waving goodbye as if he were hea
