On July 20, 1969, astronauts Neil Armstrong and "Buzz" Aldrin stepped onto the Sea of Tranquility, becoming the first humans to grace the moon. Shortly thereafter, the Soviets, plagued by system failures of their Soyuz 7K-L1 spacecraft, abandoned all hope of doing the same. Now the Russians may get to the moon after all, at least if the Arlington, Virginia, firm Space Adventures has its way—and you can tag along (if you start routinely winning the lottery). The company, which has sent two wealthy businessmen, Dennis Tito and Mark Shuttleworth, to the International Space Station atop Russian rockets, has announced a joint venture with the Russian Federal Space Agency (FSA) to embark one cosmonaut and two billionaires on a trip around the moon in an upgraded Soyuz craft by 2010. The ticket price: $100 million per person. The 8- to 15-day mission, which would mark the first time humans have ventured beyond Earth's orbit since the last Apollo mission in 1972, might include a stop at the ISS after launching from Kazakhstan. Then the crew would rendezvous with a rocket already waiting in orbit to blast toward the moon. Traveling at more than 24,000 miles an hour, the Soyuz would use the moon's gravity to slingshot around to the farside and then return home. If the flight is a success, the company will launch increasingly more ambitious missions, says Space Adventures president and CEO Eric Anderson. "Eventually we'll land on the moon," he predicts.
