When Earth’s gravity meets a shrinking Moon, lunar quakes shake it up

His voice adds a lot of gravitas to a new NASA video that plays out like a trailer for the agency's 2024 moon ambitions. And he said America can't do that without what it learns by going back to the Moon first.

Besides basic financing, the mission will also require the most powerful rocket ever designed, a new launch system, a fresh approach to lunar landing systems, a floating "gateway" station between Earth and the Moon that does not now exist, and brand new lunar space suits for everyone. "It's not coming from any part of NASA", he said. "I would encourage members of Congress in a bipartisan way to think about that when they go forward". "I am updating my budget to include an additional $1.6 billion so that we can return to space in a BIG WAY!".

NASA has revealed its upcoming moon mission, which is now tied to an ambitious 2024 deadline, will be led by both male and female astronauts for the first time.

"The last person walked on the Moon in 1972". Using the same technology, that would translate into about $200 billion today.

"A low-priced return to the moon is feasible. It is not easy, but it is feasible", McCurdy said.

The request for the NASA funding comes as the White House has been signaling its reluctance to endorse a deal to increase spending "caps" for domestic programs backed by both parties on Capitol Hill. "So if NASA can devote existing allocations in the range of $8 billion, the U.S.is within shooting distance of a five-year goal".

Bridenstine was one of several witnesses at a hearing May 14 by the Senate Commerce Committee's space subcommittee on "The Emerging Space Environment", but most of the questions focused on topics such as space traffic management and the proposed Space Force.

"It's really remarkable to see how data from almost 50 years ago and from the LRO mission has been combined to advance our understanding of the Moon while suggesting where future missions intent on studying the Moon's interior processes should go", said LRO Project Scientist John Keller of NASA's Goddard Space Flight Center in Greenbelt, Maryland.

Theoretically, fuel could be pulled from water ice discovered in 2009 in craters at the moon's poles. An additional $651 million would also go to help speed development of NASA's massive Space Launch System rocket, built largely by Boeing, and the Orion spacecraft, built by Lockheed Martin.

Watters and his team also looked carefully at data from the Lunar Reconnaissance Orbiter and identified areas near the faults that look like they've been recently disturbed - boulders that have rolled in the near past, or evidence of landslides.

"We need to move and work more efficiently than we ever have before", he said. The researchers ran 10,000 simulations to calculate the chance of a coincidence producing that many quakes near the faults at the time of greatest stress. But he said that is now being reexamined, and private companies are being asked make proposals.

"Maybe there's different architecture", Bridenstine said.

"The important thing is that we got what we requested", he said. He said he is working on the 2021 budget request, but won't reveal that until 2020 is settled.

The shrinking of the Moon also offers up parts of the core that have loosened from the mantle. "The downstream cost estimates are likely to be decisive".
