NASA’s Orion spacecraft for the Artemis I mission was successfully recovered on December 11, 2022, off the coast of Baja California. Regan Geeseman/NASARadiation worriesNASA has studied the impact of space radiation on human health for decades, dating back to the first crewed space missions of the 1960s. Long-duration space missions to the moon and Mars will expose astronauts to radiation from cosmic rays, or high energy particles that move through space.

Often referred to as the holy grail of climate solutions clean energy, fusion has the potential to provide limitless energy without planet-warming carbon pollution. KSTAR’s work “will be of great help to secure the predicted performance in ITER operation in time and to advance the commercialization of fusion energy,” Si-Woo Yoon said. This announcement adds to a number of other nuclear fusion breakthroughs. But commercializing nuclear fusion still remains a long way off as scientists work to solve fiendish engineering and scientific difficulties. Nuclear fusion “is not ready yet and therefore it can’t help us with the climate crisis now,” said Aneeqa Khan, research fellow in nuclear fusion at the University of Manchester in the UK.

CNN —Nestled in the Pyrenees mountains, La Molina is Spain’s oldest ski resort. An industry in perilSpain has been struggling with scorching heat waves and a years-long drought, and Catalonia, the region where La Molina is located, has been particularly hard hit. But La Molina is far from the only ski resort trying to plot a future in a warmer, dryer world. “Current best estimates are that 95% of ski resorts rely on snowmaking to some extent to remain viable,” Orr told CNN. That’s exactly what the La Molina project aims to do — to see if the lab results can be replicated in the real world.

☆ NASA mission achieves most distant demo of laser communications across space

CNN —An innovative experiment flying aboard NASA’s Psyche mission just hit its first major milestone by successfully carrying out the most distant demonstration of laser communications. The tech demo was designed to be the US space agency’s most distant experiment of high-bandwidth laser communications, testing the sending and receiving of data to and from Earth using an invisible near-infrared laser. NASA/JPL-CaltechIt’s not the first time laser communications have been tested in space. The first test of two-way laser communication occurred in December 2021 when NASA’s Laser Communications Relay Demonstration launched and went into orbit about 22,000 miles (35,406 kilometers) from Earth. And the Artemis II spacecraft will use laser communications to return high-definition video of a crewed journey around the moon.

☆ Mystery canine disease: A respiratory illness is spreading among dogs and baffling veterinarians. Here’s what owners can do

The mysterious illness is described as an “atypical canine infectious respiratory disease,” the Oregon Department of Agriculture said in a November 9 news release. In other words, dogs with the unidentified illness show similar signs of an upper respiratory disease but generally don’t test positive for common respiratory diseases. The Washington Animal Disease Diagnostic Laboratory has also reported cases of a mysterious canine disease, the lab’s director told CNN in an email. While the news may be concerning, “We suggest caution rather than worry,” the Oregon Veterinary Medical Association’s website says. While this particular disease is unusual, “Periodic outbreaks of Canine Infectious Respiratory Disease Complex (CIRDC) can occur in a dog population.

One recent Pew survey found that 57 percent of Americans favor more nuclear plants, up from 43 percent in 2016. A NuScale engineer gave a tour of a control room simulator, modeling the company’s plans for new nuclear reactors, in 2013. “The demand for clean energy is almost unprecedented,” said Maria Korsnick, president of the Nuclear Energy Institute, an industry group.

Fossils embedded in rock reveal intriguing details about animals, plants and other life-forms that once called Earth home. ConsequencesCrawford Lake in Ontario is the geological site that best reflects a new epoch recognizing the impact of human activity on Earth, said geologists of the Anthropocene Working Group. The Anthropocene Working Group determined in 2016 that the epoch began around 1950 — the start of the era of nuclear testing. The international research group says that Crawford Lake in Ontario best charts humanity’s impact on Earth. Back then, it took 10 hours to relay a single image to Earth — incredibly slow by today’s standards.

[1/2] Tesla Model 3 vehicles are seen for sale at a Tesla facility in Fremont, California, U.S., May 23, 2023. REUTERS/Carlos Barria/File PhotoDETROIT, June 23 (Reuters) - As the auto industry scrambles to produce more affordable electric vehicles, whose most expensive components are the batteries, lithium iron phosphate is gaining traction as the EV battery material of choice. But technological advances have also reduced the performance gap with more widely used materials such as nickel and cobalt. Ford Motor (F.N) aims to open a $3.5 billion LFP cell manufacturing plant in western Michigan, leveraging technology licensed from China’s CATL (300750.SZ), the world’s largest EV battery maker. The rapidly increasing adoption of LFP by EV manufacturers including Tesla and Hyundai suggests those companies “are not ready to decouple from China," Meng said.

☆ Why lithium-ion batteries found in many products keep exploding
▼ + stars: | 2023-03-09 | by ( Samantha Murphy Kelly | ) edition.cnn.com time to read: +7 min

Officials believe the incident stemmed from a lithium-ion battery of a scooter found on the roof of an apartment building. “In all of these fires, these lithium-ion fires, it is not a slow burn; there’s not a small amount of fire, it literally explodes,” FDNY Commissioner Laura Kavanagh told reporters. For starters, lithium-ion batteries are now in numerous consumer tech products, powering laptops, cameras, smartphones and more. Despite the concerns, lithium-ion batteries continue to be prevalent in many of today’s most popular gadgets. For example, LFP (lithium iron phosphate) batteries don’t overheat as much as other types of lithium-ion batteries.

U.S. scientists have achieved “ignition” — a fusion reaction that produced more energy than it took to create — a critical milestone for nuclear fusion and a step forward in the pursuit of a nearly limitless source of clean energy, Energy Department officials said Tuesday. The process imploded a tiny capsule inside the hohlraum that is filled with deuterium and tritium, creating a fusion reaction. Lawrence Livermore National Laboratory"We have taken the first tentative steps toward a clean energy source," said Jill Hruby, the Energy Department's National Nuclear Security Administration. The Inflation Reduction Act provided millions in new funding for fusion projects and the White House this year convened the first fusion summit and developed a 10-year plan to commercialize fusion technology.
