NASA scientist claims that astronauts can live in tunnel-like caves on the moon caused by ancient lava

NASA astronauts could someday live in caves beneath the moon's surface, formed long ago by lava from the moon.

It could provide a natural shelter to build a future lunar base, according to a NASA astronaut in a Reddit-based Q&A.

These lava tubes are long, tunnel-like structures that have formed after the surface of a lava flow has hardened before it has been eroded.

The cave structures would provide protection against both the temperature fluctuations of the moon and harmful solar radiation, thereby reducing construction costs.

NASA geoscientist Daniel Moriarty and colleagues discussed the possibility of future moonbases during a Reddit & ask me anything & # 39; session on May 16, 2019.

The online question and answer session focused on the approaching 2024 moonshot – at & # 39; Artemis & # 39; to be mentioned – on which the American space agency is working.

However, questions were about the possibility of moonbases in the future and the steps needed to prepare the surface of the moon for human inhabitants.

& # 39; I don't think we can change anything on the surface of the moon, & # 39; wrote Dr. Moriarty in response.

& # 39; Instead, I think it makes sense to work within some of the structures and resources that are already there.

& # 39; It could be interesting to set up a store in an existing lava tube, & # 39; he added.

Setting up a base in an extinct lava tube, said Dr. Moriarty, & # 39; could provide astronauts with some protection against temperature variations and incoming solar radiation. & # 39;

Lava tubes are long, tunnel-like structures formed after the surface of a lava flow hardens and then the inside is emptied, leaving a cavity (pictured: a view of a 328-meter deep crater in the Mare Tranquillitatis of the moon, which can connect make a lava tube)

WHAT ARE LUNAL LAVA TUBES?

Lava tubes are long, natural caves that have been left behind by past volcanic activity.

They are formed when the surface of a lava flow cools and forms a hard crust above the molten rock that moves below it.

When the volume of the flowing lava decreases, the tubes can deflate and leave a hollow tunnel.

The presence of lava tubes below the moon's surface is often revealed when a part of the tunnel roof collapses and leaves a circular hole that is referred to as a & # 39; skylight & # 39 ;.

Lunar lava tubes can become up to 500 meters wide before they become unstable and can collapse under their own weight.

Tubes can also collapse due to seismic activity or bombing by meteorites.

However, lava tubes are not the only sources of the moon that can be useful to develop a future lunar base.

& # 39; For example, it might be useful to establish a base near a permanently shaded pool area to take advantage of the surface water that exists, & Moriarty added.

In fact, this is the actual plan of the China National Space Administration, which announced in April its plans to establish an international base near the icy south pole of the moon in the next decade.

The announcement of China & # 39; s space exploration timeline follows the first soft landing of a spacecraft, Chang & e-4, on the other side of the moon, back in January this year.

NASA had publicly announced that they wanted the astronauts back to the moon in March 2019.

& # 39; This time, when we go to the moon, we stay, & # 39; said NASA administrator Jim Bridenstine.

The space agency, he added, plans to use & # 39; innovative new technologies & # 39; to use to explore & # 39; more locations across the moon surface than ever before & # 39 ;.

& # 39; We will use what we learn as we go to the moon to make the next giant leap – sending astronauts to Mars. & # 39;

These plans were accelerated at the end of March after US Vice President Mike Pence announced that the Trump government wanted NASA to send astronauts to the moon in five years.

Mr. Pence made the comments during a speech at the fifth meeting of the National Space Council in Huntsville, Alabama.

In the Reddit question session, NASA scientists said they were sure that they would achieve these goals despite the accelerated time frame.

If the upcoming lunar landing is successfully delivered, this will be the seventh manned American lunar expedition, following his earlier excursions between 1969 and 1972.

The space agency is used to & # 39; major challenges & # 39; with recent provisions in the US budget that make the efforts & # 39; feasible & # 39; science added.

The 2048 mission of Artemis will send the first woman to the surface of the moon and wants to be the first manned mission to land near the southern south pole of the moon.

WHEN IS NASA BACK TO THE MOON?

In a statement in March, NASA administrator Jim Bridenstine planned to send people first to the moon and then to Mars and said: NASA is on its way to get people back on the moon by 2028.

The plan is based on the developing Space Launch System and the Orion spacecraft, together with the Gateway orbital platform.

SLS and Orion are expected to be ready for their first non-propelled test flight in 2020.

Construction on Gateway – an outpost in orbit around the moon – is expected to start as early as 2022.

& # 39; We are going to the moon in the next decade with innovative new technologies and systems to explore more locations on the moon surface than ever before & # 39 ;, said Bridenstine.

& # 39; This time we will stay if we go to the moon.

& # 39; We will use what we learn as we go to the moon to make the next giant leap – sending astronauts to Mars. & # 39;

Vice President Mike Pence, however, tore up these plans and statements when he unexpectedly announced a new deadline in March expressing intentions to put people on the moon by 2024 – four years earlier.

The VP called on NASA to re-ignite the spark of urgency for space exploration and make it a priority to & # 39; bold targets & # 39; establish and stay on schedule.

NASA administrator Jim Bridenstine added a week later, early April, that the agency would be very close to & # 39; would be to deliver a plan.

This has been missed for several weeks and the House Science Committee is now expressing its dissatisfaction about the lack of an executable plan or program from the space agency.
