Odysseus lunar lander, 1st US craft on the moon in 50 years, has died and will ‘not complete another call home’

Posted by in categories: solar power, space travel, sustainability

Odysseus, which was built by Houston-based company Intuitive Machines, powered down one week after landing as lunar night began for 14 days. Flight controllers ordered the spacecraft to snooze for three weeks, while the moon’s south pole faced away from the sun, but they hoped Odie would reawaken once sunlight hit its solar panels again.

“Intuitive Machines started listening for Odie’s wake-up signal on March 20, when we projected enough sunlight would potentially charge the lander’s power system and turn on its radio,” representatives of the company wrote on X, formerly called Twitter.

Nvidia Is Simulating a Copy of the Earth

Posted by in categories: climatology, economics, sustainability

Chipmaker Nvidia has shown off a clone of our entire planet that could help meteorologists simulate and visualize global weather patterns at an “unprecedented scale,” according to a press release.

The “Earth climate digital twin,” dubbed Earth-2, was designed to help recoup some of the economic losses caused by climate change-driven extreme weather.

Customers can access the digital twin through an API, allowing “virtually any user to create AI-powered emulations to speed delivery of interactive, high-resolution simulations ranging from the global atmosphere and local cloud cover to typhoons and turbulence.”

New technique converts excess renewable energy to natural gas

Posted by in categories: biological, chemistry, sustainability

Four Lawrence Livermore National Laboratory (LLNL) researchers have partnered with Los Angeles-based SoCalGas and Munich, Germany-based Electrochaea to develop an electrobioreactor to allow excess renewable electricity from wind and solar sources to be stored in chemical bonds as renewable natural gas.

When renewable electricity supply exceeds demand, electric-utility operators intentionally curtail production of renewable electricity to avoid overloading the grid. In 2020, in California, more than 1.5 million megawatt hours of renewable electricity were curtailed, enough to power more than 100,000 households for a full year.

This practice also occurs in other countries. The team’s electrobioreactor uses the renewable electricity to convert water into hydrogen and oxygen. The microbes then use the hydrogen to convert carbon dioxide into methane, which is a major component of natural gas. Methane can then be moved around in natural gas pipelines and can be stored indefinitely, allowing the renewable energy to be recovered when it is most needed.

Harnessing Hemp: Empowering Native American Economies

Posted by in categories: economics, education, food, sustainability

“There is still significant interest and potential in industrial uses of hemp,” said Dr. Jeffrey Steiner.


How can hemp production help boost local Native American economies? This is what a $10 million grant from the U.S. Department of Agriculture’s (USDA) National Institute of Food and Agriculture hopes to achieve as they recently awarded this grant to the Global Hemp Innovation Center at Oregon State University (OSU) to foster collaboration with 13 Native American Tribes across the western United States, including California, Montana, Nevada, Idaho, Washington, and Oregon with the goal of creating economic stimuli for those communities while improving hemp production.

The grant comes with four primary objectives in achieving collaboration with the 13 Tribal nations, including educational opportunities, technology development, building trade networks, and ensuring product quality. This grant comes as the 2018 Farm Bill helped legalize hemp, leading to hemp production reaching $824 million across the United States in 2021.

Company develops revolutionary technology that allows wind turbines to practically build themselves: ‘It will be a gamechanger’

Posted by in categories: futurism, sustainability

“Gigantic aluminum spiders” might sound like the stuff of nightmares or an antagonist in an anime series. However, for one Norwegian company, they could be the future of the wind energy industry.

WindSpider, a tech company that focuses on onshore and offshore wind turbines, has developed a new self-erecting crane system that could revolutionize the way turbines are built.

Unveiling Cosmic Secrets and Earth’s Mysteries With NASA’s Latest CubeSat Fleet

Posted by in categories: education, satellites, solar power, sustainability

NASA ’s CubeSat Launch Initiative (CSLI) is sending four CubeSats to the International Space Station to advance space-based technologies in solar power, gamma-ray burst detection, and water monitoring. Developed in collaboration with universities and NASA, these satellites aim to enhance our understanding of cosmic phenomena and Earth’s environmental dynamics.

NASA’s CubeSat Launch Initiative is sending a group of four small satellites, called CubeSats, to the International Space Station (ISS) as ELaNa 51 (Educational Launch of Nanosatellites). These small payloads have been developed by NASA and universities and will be deployed from low Earth orbit.

Once circling Earth, the satellites will help demonstrate and mature technologies meant to improve solar power generation, detect gamma-ray bursts, determine crop water usage, and measure root-zone soil and snowpack moisture levels.
