Mining The Sea or Mining The Sky?

Posted by in categories: climatology, habitats, sustainability

An intense discussion is now going on at the International Seabed Authority (ISA), starting in March 2024, and proceeding up to August, for its various instances, committees, and general assembly. The most critical point concerns the call for licenses, which are being advanced by several commercial mining entities, to explore deep sea grounds, seeking rare minerals highly in demand, fueling the energy and green transitions worldwide. Clean energy technologies require more materials, such as copper, lithium, nickel, cobalt, aluminum, and rare earth elements, than fossil fuel-based technologies. Demand for critical minerals could surge 450% by 2050 to meet Paris Agreement climate goals[1]. The deep sea, particularly in the form of polymetallic nodules (PMNs), contains significant cobalt resources. Estimates suggest that by 2035, deep-sea mining of PMNs could produce 61,200 tons of cobalt per year, which could account for up to 50% of current annual global cobalt demand[2].

For the first time, ISA is considering the revision of deep-sea mineral exploitation regulations [3]. Commercial deep-sea mining has attracted increased attention, particularly owing to potential oceanic challenges, including pollution, overfishing, biodiversity, and habitat loss, acidification, rising water temperatures, and climate change. Those favoring commercial mining highlight the need for a supply of materials necessary for global energy transition. Recent meetings in Kingston, Jamaica, have focused on revising the draft regulations for deep-sea mineral exploitation. While some progress has been made, several areas of disagreement remain, particularly regarding environmental protections and the speed of issuing commercial permits. The ISA is aiming to finalize the new regulations by July 2025, but there are concerns that this deadline may not be met.

On the commercial side, The Metals Company (TMC), Canada, anticipates submitting an application for a mining exploitation license in 2024, potentially starting mining operations in 2025, even before the regulations are fully in place. While ISA has not granted any commercial licenses for deep-sea mining, some countries are moving forward independently. Norway already passed a bill in January 2024, which authorizes prospecting for deep-sea minerals, accelerating the hunt for the precious metals that are in high demand for green technologies. Environmental scientists have warned such oceanic exploitation could be devastating for marine life. The outlook concerns Norwegian waters, nevertheless, agreements on mining in international waters could also be reached this year.

Mysterious Maya underground structure unearthed in Mexico

Posted by in category: habitats

Archaeologists in Mexico have discovered a mysterious subterranean structure with painted walls hidden beneath a Maya ball court.

The team found the building while excavating the ball court, the playing space for the ritual ball game played by the Maya and other Mesoamerican peoples.

NASA is considering Other Ways of getting its Mars Samples Home

Posted by in categories: alien life, habitats

In 2021, NASA’s Perseverance rover landed in the Jezero Crater on Mars. For the next three years, this astrobiology mission collected soil and rock samples from the crater floor for eventual return to Earth. The analysis of these samples is expected to reveal much about Mars’ past and how it transitioned from being a warmer, wetter place to the frigid and desiccated place we know today. Unfortunately, budget cuts have placed the future of the proposed NASA-ESA Mars Sample Return (MSR) mission in doubt.

As a result, NASA recently announced that it was seeking proposals for more cost-effective and rapid methods of bringing the samples home. This will consist of three studies by NASA and the Johns Hopkins University Applied Physics Laboratory (JHUAPL).

In addition, NASA has selected seven commercial partners for firm-fixed-price contracts for up to $1.5 million to conduct their own 90-day studies. Once complete, NASA will consider which proposals to integrate into the MSR mission architecture.

Europol says Home Routing mobile encryption feature aids criminals

Posted by in categories: encryption, habitats, law enforcement

Europol is proposing solutions to avoid challenges posed by privacy-enhancing technologies in Home Routing that hinder law enforcement’s ability to intercept communications during criminal investigations.

The agency has previously highlighted in its Digital Challenges series that law enforcement problem of end-to-end encryption on communication platforms is a hurdle when it comes to collecting admissible evidence.

Glaze — What is Glaze

Posted by in categories: economics, education, habitats, robotics/AI

Generative AI models have changed the way we create and consume content, particularly images and art. Diffusion models such as MidJourney and Stable Diffusion have been trained on large datasets of scraped images from online, many of which are copyrighted, private, or sensitive in subject matter. Many artists have discovered significant numbers of their art pieces in training data such as LAION-5B, without their knowledge, consent, credit or compensation.

To make it worse, many of these models are now used to copy individual artists, through a process called style mimicry. Home users can take art work from human artists, perform “fine-tuning” or LoRA on models like stable diffusion, and end up with a model that is capable of producing arbitrary images in the “style” of the target artist, when evoked with their name as a prompt. Popular independent artists find low quality facsimilies of their artwork online, often with their names still embedded in the metadata from model prompts.

Volunteer Crew to Exit NASA’s Simulated Mars Habitat After 378 Days

Posted by in categories: habitats, health, space travel

The four volunteers who have been living and working inside NASA’s first simulated yearlong Mars habitat mission are set to exit their ground-based home on Saturday, July 6. NASA will provide live coverage of the crew’s exit from the habitat at NASA’s Johnson Space Center in Houston at 5 p.m. EDT.

NASA will stream the activity, which will include a short welcome ceremony, on NASA+, NASA Television, the NASA app, the agency’s website, and NASA Johnson’s X and Facebook accounts. Learn how to stream NASA TV through a variety of platforms, including social media.

The first Crew Health and Performance Exploration Analog (CHAPEA) mission began in the 3D printed habitat on June 25, 2023, with crew members Kelly Haston, Anca Selariu, Ross Brockwell, and Nathan Jones. For more than a year, the crew simulated Mars mission operations, including “Marswalks,” grew and harvested several vegetables to supplement their shelf-stable food, maintained their equipment and habitat, and operated under additional stressors a Mars crew will experience, including communication delays with Earth, resource limitations, and isolation.

Mission Success: HERA Crew Successfully Completes 45-Day Simulated Journey to Mars

Posted by in categories: habitats, space

Four dedicated explorers—Jason Lee, Stephanie Navarro, Shareef Al Romaithi, and Piyumi Wijesekara—just returned from a 45-day simulated journey to Mars, testing the boundaries of human endurance and teamwork within NASA’s HERA (Human Exploration Research Analog) habitat at Johnson Space Center in Houston.

Their groundbreaking work on HERA’s Campaign 7 Mission 2 contributes to NASA’s efforts to study how future astronauts may react to isolation and confinement during deep-space journeys.
