"Well I think we need to build up an alliance. And since we've been marking time for 10, 15 years I would call it the next step," Aldrin said in an interview that aired Saturday.

"Space Alliance. Those are the capable space agencies and commercial activities that can make up the capability to carry out things."

Aldrin voiced his concerns with the lack of advancement by NASA half a century after his lunar module became the first entity to land on the moon.

Asked what he thinks about when he looks at the moon, the astronaut appeared to focus on looking forward rather than backward as he noted the possible discovery of ice crystals.

"The ice crystals are still there so that means we can melt that that's water. Water is hydrogen-oxygen and that's rocket fuel," Aldrin said.

Aldrin was still able to reflect on Apollo 11 mission and his experience on the surface of the moon.

"To me it was a magnificent tribute to all of humanity and especially to the United States to be able to carry out this sort of a challenge," Aldrin said.
