Rocket PlaceShipOne is to make a second attempt for spaceflight on Monday. Its main purpose is to clinch $10m Ansari X-prize.

The judges have confirmed that on Wednesday that Pilot Mike Mevil had successfully taken the craft to 103 km (64 Miles).

Under the rules of the X-Prize, the contender must obtain the 100 km mark twice within 2 weeks in the same craft.

But the second attempt seems to be delayed because the spacecraft rolled unexpectedly during its previous flight If the delay is a little longer, the X-prize may become doubtful.
