Recover old data before it’s too late



Recover old data before it’s too late

In the late 19th century, astronomers began imaging the stars using light prisms and gratings. They recorded the spectra (dispersion of starlight into colors) of stars to determine what they were made of. Since then, these photos have also become useful for another purpose: They allow scientists to chart past concentrations of ozone in the Earth’s stratosphere and help reveal whether some changes in the ozone hole are natural. The hardest part of the whole process is finding these glass panels. I know this because I spent several weeks reviewing collections at various observatories around the world – from Germany to Australia.

What other historical data would be useful? There are many stories about this; Thousands of records made during sailing voyages over the past centuries are a treasure trove that can be used to study weather patterns today. Images of glaciers from the past and present have mesmerized the entire world and led to indisputable evidence of climate change. Medical records from old punch cards — left in the late 1950s and decoded decades later — have helped show how cholesterol levels can predict later disease.

To imagine the future, we must first study the past, but opportunities to do so are quickly fading, fueled by misunderstanding and neglect. Whether stored on glass plates, written on paper, old tapes, or floppy disks, only a few different forms of “heritage data” are readily available for research today, so the information recorded in them is effectively lost.

Scientists complained that they could not get enough data. Today we talk about “big data” like an untamed beast. The metrics being collected now are becoming increasingly complex, but they only tell us about the present. Measurements recorded long ago can show how climate, ecology, and other changes have changed on Earth, and data taken from individuals decades ago can inform modern medical and policy guidelines. To get that data, you need to start recovering it now.

The important question now is: Why don’t scientists in all fields seek to preserve ancient records, even if they are the best way to study long-term trends in change? Part of the answer lies in human psychology. At a talk I gave about the need to convert nearly lost astronomical data into long-term, easily shareable data, one audience member said: “Modern data is great.”

He missed the point. Few people have the desire to dig through old archival records, legacy data that yield information obtained using outdated technology but not available in any other format. Hydrologists in Cape Town, South Africa, have digitized handwritten data dating back 70 years – to find out how non-native tree species affect water supply in natural environments. High-resolution color images of existing birds cannot replace images of the now-endangered migratory pigeon and laughing owl.

“The hidden treasures of data—all the knowledge they have to offer—are left to rot on the shelves.”

It is time to save the traditional data, and ancient scholars are still alive who can provide the necessary correct information about the surrounding conditions. Techniques for digitizing many types of records are cheap and easy to access.

But digitization does not preserve everything. At least one epidemiologist has identified the spread of cholera in the Iberian Peninsula by inhaling envelopes. How is that? For centuries, post offices have used vinegar. To disinfect mail delivered from infected cities, it still had scent on it.

So what can we do? The Data Recovery Interest Group of the International Research Data Alliance provides guidelines (; To guide the researcher through the initial stages of data recovery, determine the necessary equipment and determine the best way to tackle the recovery process. The most important conditions for obtaining data from large-scale past human changes are identified. Many fields—such as biodiversity (, volcanology, and oceanography—have made great strides in preserving ancient data, but more needs to be done quickly and with better coordination.

The truth is that not all data can be saved. Setting priorities means looking for an opportunity to shed light on otherwise unanswerable questions. Researchers often dismiss traditional materials without considering their potential applications. Hidden treasures of data – with all the knowledge it can provide – are left to rot on shelves.

Everyone can lend a helping hand. The first challenge is finding records, photographs or other objects or understanding their value. Most of it has not been used for a long time, stored almost abandoned, and moisture, spiders and mice often do their best to destroy it.

A second challenge is ensuring that the necessary metadata (such as date, location, and constraints) exists so that the time and location of that data can be accurately determined when converted to modern formats.

Finding the resources needed for conservation is often difficult, and funding is scarce and disorganized, but activists have secured grants from agencies ranging from NASA to the US Agency for International Development and the German Research Foundation. The payoff is worth casting a wide net. University archivists can share their expertise and mobilize citizen science groups.

An important neglected resource is success stories. When researchers examine data that was once neglected and brought back to life in modern form, they are likely to discover hidden opportunities themselves. The next heroic rescue story may be your mission, but you must hurry; Some data is destroyed while writing this article, some may not be recovered tomorrow, and old memories we need to use may not be with us for a long time.

NASA is preparing to build an advanced internet network on the moon – MusicNation



NASA is preparing to build an advanced internet network on the moon – MusicNation

NASA is currently in the early stages of developing the LunaNet, an Internet network on the Moon that goes beyond exchanging information between astronauts in space and people on Earth. The agency plans to build a vast infrastructure around the moon to connect everything from a human habitation, a new space station, and a lunar network service.

“All the cell towers and Wi-Fi hot spots on Earth today, and the things that provide network connectivity, have changed the way we work in our daily lives,” says Dave Israel, principal investigator for NASA’s Goddard Space Program. Aviation center. What we want to do today is make this experience available to astronauts and robotic missions to the Moon, and then extend it to Mars and wherever we go.

But it is not without challenges; Because data transmission between the Earth and the Moon is not easy, especially since the South Pole of the Moon and its distance does not directly face the Earth. Transportation is another obstacle because there are not many trips to the moon, which means it may take a long time to transport lunar internet equipment. We await several upcoming launches, the first of which will be the manned “Artemis 2” mission in 2024, which will include tests of lunar communication technology. However, the researcher does not expect this technology to be fully ready and operational by the end of this decade.

On Earth we use satellites that have been in orbit for years to connect to the network. Companies such as SpaceX, OneWeb and Amazon are currently building networks of thousands of satellites in low-Earth orbit to provide fast service from space. In turn, the International Space Station also has its own connection to the Internet, unlike the Moon.

Kelly Larson, CEO of Aquarian Space, a startup focused on lunar communications, explains, “The data rates customers currently receive on the moon are not a connection, but a battle for connectivity.”

To improve the service, NASA plans to launch lunar satellites that will communicate with each other and then connect to communications infrastructure on Earth. In the case of the lunar south pole, a remote area that NASA hopes astronauts will eventually reach, switching between spacecraft is considered a viable solution. The company also intends to deploy a fleet of ground stations that will play the role of cell towers on the lunar surface.

Private companies play an important role in building new Internet infrastructure. Aquarien Space, for example, plans to launch the first group of lunar communications satellites in the second quarter of 2025, and hopes that its technology will finally succeed in delivering 100 megabits per second without interference to the lunar surface. NASA is also collaborating with Nokia to build a cellular network for the Moon using fourth-generation technology. Nokia won a $14 million contract from the company, and its first platforms and radio equipment are set to launch to the moon next year on a SpaceX rocket.

In turn, the European Space Agency is working on a parallel project called “Moonlight,” which is based on contracting companies to build lunar communications infrastructure.

These plans to speed up the use of Internet connectivity on the Moon are aimed at securing basic logistics. As the number of human and robotic observers on the lunar surface increases,

The need for communication networks to help determine directions, such as the popular GPS technology on Earth, will increase. The “Luna Net” project could help in monitoring astronauts’ health and lunar weather conditions, as well as organizing activities on the lunar surface and in its orbit.

Are aliens hiding on Mercury? Scientists explain the nature of life on this planet



Are aliens hiding on Mercury? Scientists explain the nature of life on this planet

By Amira Shehata

Friday, December 8, 2023 01:00 AM

Scientists revealed that Mercury’s North Pole A new study by the Institute for Planetary Research suggests that life may exist within the salty glaciers hidden beneath the surface of an uninhabitable planet, which may have the right conditions to support some type of alien.

According to the British newspaper “Daily Mail”, researchers say that despite the harsh conditions, there are similar regions on Earth.

Dr. Alexis Rodriguez, principal investigator of the study, said: “This thought leads us to consider the possibility that beneath the surface of Mercury there are regions more suitable for life than its hard surface.”

Using images from NASA’s MESSENGER probe, the researchers studied the geology of Mercury’s north pole, where researchers found evidence that salt glaciers may have flowed through the planet’s Raditladi and Eminescu craters.

But these glaciers are not like the ones we know on Earth, and instead of ice, Mercury’s glaciers are made of salts that trap volatile compounds like water, nitrogen, and carbon dioxide.

When Mercury collided with space rocks, craters blasted through the basalt rock’s outer layer, allowing these volatile compounds to escape from Earth and form glaciers. As the closest planet to the Sun, Mercury reaches temperatures of 806 degrees Fahrenheit (430 degrees Celsius). ) during the day, meaning that these volatile chemicals have evaporated.

However, scientists were able to locate the glaciers by looking for recognizable features of the Earth.

Dr Rodrigues said: “Our models strongly confirm that salt flow could have formed these glaciers and that they retained their volatiles for more than a billion years after emplacement.”

Mercury may have a large layer of salt beneath its surface, hidden from the Sun’s intense heat and rich in volatile compounds that could support life.

Dr. Rodriguez points out that similar habitats are capable of supporting life on Earth, “The salt compounds identified on Earth create a habitable environment even in some extreme environments, such as the arid Atacama Desert in Chile.”
