Two more attempts to win the $10 million Ansari X-Prize went up-and down-in smoke this weekend. Team, funded by John Carmack of id Software, hoping to send a rocket into space saw its craft crash and burn this weekend. Armadillo Aerospace lost a $35,000 rocket when the machine ran out of propellant at close to 600 feet and came tumbling back to earth.

The other failure happened on August 8 at Olympia National Park in Washington state. The $20,000 rocket built by Space Transport Corp. of Forks, Wash., exploded as it reached 1000 ft. Co-founder Eric Meier said he's planning another test launch in the next couple of months. Eric Meier on Wednesday put the remains of the Rubicon 1 rocket up for online auction at eBay.com.

The first private manned spaceflight took place in June, when SpaceShipOne, a craft funded by billionaire Microsoft co-founder Paul Allen and designed by aviation pioneer Burt Rutan, reached the required altitude on a test flight.
