The deployment of DAS and other science experiments will be part of the surface operations of the Artemis missions. It will be part of one of the proposed seven-month stays for astronaut teams. Although there is no specific planned date for seismometer deployment, it’s likely to take place no sooner than the mid-2030s.

NASA says Artemis 3 astronauts will install moonquake detector

NASA plans to have Artemis 3 astronauts place a moonquake detector on the Moon when the mission lands

NASA said this week its Goddard Space Flight Center in Greenbelt, Maryland is building a moonquake detector for astronauts to deploy when they land on the Moon during the Artemis 3 mission.

The space agency selected the instrument, the Lunar Environment Monitoring Station (LEMS) as one of the first three potential payloads of Artemis 3. LEMS is a compact, autonomous seismometer made to sustain long-term monitoring of ground motion from moonquakes around the celestial body’s south pole.

It is intended to work on the lunar surface from three months up to two years and could become a key station in a future global lunar geophysical network. Moonquakes were first observed by Apollo missions when they placed seismometers between 1969 and 1972.These quakes are caused by the same tug of gravity that causes ocean tides. The Moon’s surface trembles as it expands and contracts due to temperature changes

NASA has chosen the first science instruments designed for astronauts to deploy on the surface of the Moon during Artemis III. Once installed near the lunar South Pole, the three instruments will collect valuable scientific data about the lunar environment, the lunar interior, and how to sustain a long-duration human presence on the Moon, which will help prepare NASA to send astronauts to Mars.

Once installed near the lunar South Pole, the three instruments will collect valuable scientific data about the lunar environment, the lunar interior, and how to sustain a long-duration human presence on the Moon, which will help prepare NASA to send astronauts to Mars.

“Artemis marks a bold new era of exploration, where human presence amplifies scientific discovery. With these innovative instruments stationed on the Moon’s surface, we’re embarking on a transformative journey that will kick-start the ability to conduct human-machine teaming – an entirely new way of doing science,” said NASA Deputy Administrator Pam Melroy. “These three deployed instruments were chosen to begin scientific investigations that will address key Moon to Mars science objectives.”

The Lunar Environment Monitoring Station (LEMS) is a compact, autonomous seismometer suite designed to carry out continuous, long-term monitoring of the seismic environment, namely ground motion from moonquakes, in the lunar south polar region. The instrument will characterize the regional structure of the Moon’s crust and mantle, which will add valuable information to lunar formation and evolution models. LEMS previously received four years of NASA’s Development and Advancement of Lunar Instrumentation funding for engineering development and risk reduction. It is intended to operate on the lunar surface from three months up to two years and may become a key station in a future global lunar geophysical network. LEMS is led by Dr. Mehdi Benna, from the University of Maryland, Baltimore County.

What will the Artemis crew be doing on the Moon?

Four astronauts will fly around the Moon to test NASA’s foundational human deep space exploration capabilities, the Space Launch System rocket and Orion spacecraft, for the first time with crew

Is there a seismometer on the Moon?

The Moon is the only planetary body other than the Earth to have had more than one seismometer on it at a time. It gives us the only opportunity to thoroughly study another body,” says Husker

Will Artemis astronauts land on moon?

According to plan, the crewed Artemis 2 launch will take place in late 2025, the Artemis 3 crewed lunar landing in 2026, the Artemis 4 docking with the Lunar Gateway in 2028, and future yearly landings on the Moon thereafter.

What was the first seismometer on the Moon?

The first lunar seismometer was set up by Neil Armstrong and Buzz Aldrin on the Apollo 11 mission. After deploying the instrument, Aldrin stamped on the lunar surface to check it was working – with the instrument picking up the waves produced by his foot

Who built the seismometer?

The first seismometer was made in China during the 2nd century. It was invented by Zhang Heng, a Chinese mathematician and astronomer. The first Western description of the device comes from the French physicist and priest Jean de Hautefeuille in 1703. The modern seismometer was developed in the 19th century

What is the oldest seismometer?

The earliest seismoscope was invented by the Chinese philosopher Chang Heng in A.D. 132. This was a large urn on the outside of which were eight dragon heads facing the eight principal directions of the compass

Who touched the Moon first?

Neil Armstrong

Neil Armstrong on the Moon

At 02:56 GMT on 21 July 1969, Armstrong became the first person to step onto the Moon.

How did the first seismometer work?

The First Earthquake Detectors

Whenever there was even a slight earth tremor, a mechanism inside the seismograph would open the mouth of one dragon. The bronze ball would fall into the open mouth of one of the toads, making enough noise to alert someone that an earthquake had just happened

What is called seismometer?

A seismometer is the internal part of the seismograph, which may be a pendulum or a mass mounted on a spring; however, it is often used synonymously with “seismograph”. Seismographs are instruments used to record the motion of the ground during an earthquake

What is a seismometer used for?

Seismometers allow us to detect and measure earthquakes by converting vibrations due to seismic waves into electrical signals, which we can then display as seismograms on a computer screen

Who is the father of seismic?

Robert Mallet

Robert Mallet (born June 3, 1810, Dublin, Ireland—died November 5, 1881, London, England) Irish geophysicist, civil engineer, and scientific investigator who is sometimes called the “father of seismology” for his work on earthquakes

What is the difference between a seismograph and a seismometer?

A seismometer is a digital seismic wave recorder. A seismograph is an instrument that measures and records details of earthquakes, such as force and duration. On the other hand, a seismogram is the record produced by a seismograph

How old is seismology?

At present seismology is the study of seismic sources (mostly earthquakes), the waves they produce, and the properties of the media through which these waves travel. In its modern form the subject is just over 100 years old, but attempts to understand earthquakes go back to the beginnings of science

Does a seismometer need electricity?

Modern research seismometers are electronic, and instead of using a pen and drum, the relative motion between the weight and the frame generates an electrical voltage that is recorded by a computer

How do modern seismometers work?

Most modern seismometers work electromagnetically. A large permanent magnet is used for the mass and the outside case contains numerous windings of fine wire. Movements of the case relative to the magnet generate small electric signals in the wire coil

Back in the 1960s and 1970s, Apollo astronauts set up a collection of lunar seismometers to detect possible Moon quakes. These instruments monitored lunar activity for eight years and gave planetary scientists an indirect glimpse into the Moon’s interior. Now, researchers are developing new methods for lunar quake detection techniques and technologies. If all goes well, the Artemis astronauts will deploy them when they return to the Moon

The new approach, called distributed acoustic sensing (DAS), is the brainchild of CalTech geophysics professor Zhongwen Zhan. It sends laser beams through a fiber optic cable buried just below the surface. Instruments at either end measure how the laser light changes during the shake-induced tremors. Basically Zhan’s plan turns the cable into a sequence of hundreds of individual seismometers. That gives precise information about the strength and timing of the tremors. Amazingly, a 100-kilometer fiber optic cable would function as the equivalent of 10,000 seismometers. This cuts down on the number of individual seismic instruments astronauts would have to deploy. It probably also affords some cost savings as well

LEMS is a compact, autonomous seismometer designed to carry out continuous, long-term monitoring of ground motion from moonquakes in the region around the lunar South Pole. The data LEMS gathers will help scientists study the moon’s internal structure and could help refine our understanding of how the moon formed. Two other devices were also selected for deployment

The Artemis missions and its importance in space exploration

NASA’s Artemis program is a series of missions to explore the moon and prepare for human missions to Mars. The program’s goals include: 

• Equality: Landing the first woman and first person of color on the moon 
• Technology: Developing technologies for future deep-space missions 
• Long-term presence: Establishing bases on the moon’s surface and in lunar orbit 
• Mars: Laying the foundation for sending humans to Mars

The Artemis program is named after the Greek moon goddess, the twin sister of the god Apollo. The first missions to take astronauts to the moon were called the Apollo program, which landed the first man on the moon in 1969. The Artemis program is intended to reestablish a human presence on the moon for the first time since Apollo 17 in 1972. 

The Artemis program began in 2017 and is intended to return astronauts to the moon during the 2020s for the first time since 1972. The program will collaborate with commercial and international partners, and use innovative technologies to explore more of the lunar surface than ever before. 

In December 2020, NASA announced the Artemis team of astronauts, which included nine women and nine men. In August 2022, chief astronaut Reid Wiseman announced that all active NASA astronauts are eligible for Artemis missions. 

The Artemis program will teach us more about our Earth and solar system, leading to further discoveries in the future

Why is Artemis 3 important

Artemis 3 is the first crewed mission of the Artemis program, and the first time humans will return to the lunar surface since Apollo 17 in 1972. It will also be the first time humans explore the region near the lunar South Pole. The mission will build on the Artemis II flight test, adding new capabilities with the human landing system and advanced spacesuits

Artemis 3 is planned to launch in 2026, but the Government Accountability Office reported in December 2023 that the mission is not likely to occur before 2027. NASA officially expects Artemis 3 to launch no earlier than September 2026 due to issues with the valves in Orion’s life support system. 

The mission will launch the Space Launch System (SLS) megarocket and Orion spacecraft. For landing on the moon, the crew will use SpaceX’s Starship, a system that the California company is developing right now for crewed human missions.

What will Artemis missions teach us

Artemis will teach us how to live and work on another world, and how to move safely across lunar soil. It will also help us learn how to build infrastructure on the moon, and how to keep humans safe in space. The mission will also teach us more about our Earth and solar system, leading to further discoveries about the universe

Some priorities for Artemis III include:

• Conducting experimental science on the moon 
• Investigating and mitigating the risks of exploration 
• Understanding the origin of the elements at the lunar poles, like water and other resources that could be used by astronauts 

The Artemis program will also help us learn how to survive in space. For example, the rocket has been equipped with scientific experiments to test how deep space affects our bodies

This will teach us how to move safely across lunar soil, known as regolith; how to build infrastructure on top of it; and how to keep humans safe in space
