The U.S. space agency NASA has set a goal to return humans to the moon by 2024.
As part of preparations NASA plans to send exploration vehicles to
the moon to examine the planet’s huge water supply. The effort will
follow up on a 2009 mission that confirmed the presence of water beneath the moon’s surface.
That mission, called LCROSS, sent a rocket crashing into the moon’s south pole. The crash sent debris flying from the moon’s surface and identified a large collection of water ice.
LCROSS was a major development in discovering this important resource on the moon.
NASA Administrator Jim Bridenstine called the LCROSS mission “a game
changer.” He said the U.S. “should have immediately as a nation changed
our direction to the moon so we could figure out how to use it.”
He spoke with Reuters news agency.
Bridenstine said the moon holds billions of tons of water ice.
Experts have said the exact amount of water on the moon is not known.
They have also said it is unclear whether the water is present in large
pieces of ice or combined with moon soil.
So to learn more, NASA is working with a few companies to put exploratory vehicles on the moon’s surface by 2022.
Jack Burns is the director of the Network for Exploration and Space
Science at the University of Colorado. He told Reuters it is important
for such vehicles to get to the moon. They will be able to search for
water, drill into the surface, and attempt to find ways to bring the water out.
Scientists say the water could be very useful in future activities on
the moon. For example, they believe it may be possible to one day break
down the water into its two main parts, hydrogen and oxygen. This could
possibly be used to provide fuel for missions to deeper parts of the
solar system.
Tony Colaprete was one of the main investigators for the LCROSS
mission. He told Reuters that in the final weeks before the launch, the
project experienced “a bad rush to the finish line.”
“We wanted to make as large of a hole as possible to get as many
materials out of the shadows and into the sunlight,” Colaprete said. He
said the fast-moving mission used some technology that had never been
used in space before.
Colaprete added that the current moon program is also “forcing some
cultural changes” at NASA. The U.S. space agency has experienced a
series of high-level leadership changes and delays in the agency’s commercial crew program. That program aims to return U.S. human spaceflight for the first time since 2011.
Colaprete said in his opinion, “people are coming together in a way like they did on LCROSS.”
