But the pyramid shafts are a different type of spelunking and the Supreme Council of Antiquities was determined that whoever they selected for the next mission would leave no footprints at all.To select which team—Singapore or Leeds—was best able to fulfill the mission and meet all the criteria, Zahi Hawass arranged for the two sides to face off in a sort of robot Olympics in the desert.
The mission had confirmed that the 20 x 20 cm blocking slab and the final section of U-block were made of a higher quality type of limestone than the rest of the shaft, most likely the fine limestone quarried at Tura rather than the rougher local yellow limestone.
To accomplish these objectives, the mission would have to meet certain criteria as well.
The tube-mounted camera on Pyramid Rover was unable to look around the inside of the chamber and the light quality was not fully up to task.
Larger, more structural questions presented themselves as well. Did the shaft continue on the opposite side, or come to an abrupt end against the core masonry of the pyramid? Zahi Hawass, the Secretary of the Supreme Council of Antiquities, had some decisions to make.
Was the block inserted into the shaft like a cork, or did it sit flush against the end of the shaft like a lid? Initial planning for the next mission into the Queen’s Chamber shafts began soon after the conclusion of the Pyramid Rover Project, and at one point it seemed that a team from Singapore University had been selected as early as August, 2004. Hawass talked as if the Singaporean mission was a done deal.
