New Mexico wildfire has charred at least 4,000 acres and shows no sign of containment






America で又大規模なWildfireが発生していますと言う報道です。



(CNN)The Three Rivers Fire has burned 4,000 acres in New Mexico and has not been contained, according to a press release on the New Mexico Fire Information site.
The fire "is being driven by steep terrain and extreme fire weather conditions, including gusty winds and low humidity levels around 8 percent," the release said.
There has been no containment of the blaze, which is burning about 60 miles northeast of White Sand National Park and about three hours south of Albuquerque.
"The fire started ½ a mile north of Three Rivers Campground and has spread almost to Ski Apache and into the South Fork Bonito area," the release said.

Georgia mom blasts school board for making kids wear COVID face masks: ‘Take these masks off of my child’










A Georgia mom is going viral after she grilled school board members for making young children wear masks and socially distance despite there being little evidence that kids are severely at risk of contracting COVID-19.

Courtney Ann Taylor slammed the Gwinnett County Board of Education members at a meeting on April 15, telling them that she’s heard the same talk for over a month about kids’ social and mental health.

Everything an F/A-18 Fighter Pilot Wears in the Cockpit

Like motorcyclists, U.S. Navy pilots “dress for the slide, not the ride.” Their gear is meant for frost, flames, and flotation. Even the very first pilot to operate from a ship carried safety equipment: Eugene Ely, attempting his landing on the deck of the armored cruiser USS Pennsylvania in 1911, took the controls of his Curtiss Pusher wearing a leather football helmet, bug-eyed motoring goggles, and a makeshift life vest fashioned from bicycle inner tubes.

The odds of a mission ending with an ejection from the cockpit are slim—it happens precisely 1.33 times per 100,000 hours of flying, according to the Navy. But naval flight officers still carry equipment for just such a scenario. “Most of the gear is only for emergency use,” says Lt. Luke “Oslo” DeLisio, a flight officer from Strike Fighter Squadron (VFA) 106. “But when you need it, you’re glad it’s there.”

“Like Wearing Your Pajamas to Work”
Starting from the inside out, pilots and aircrew wear cotton undergarments. In the event of a cockpit fire, cotton won’t melt and fuse to a crew member’s skin the way nylon or polyester would.

NASA will attempt to fly its Mars helicopter on April 19th




NASA火星計画 Mars Helicopterを飛ばす計画であるとの記事からです。






NASA finally has a new flight date for its Mars helicopter after a bug fix prompted a delay. The space agency now expects to fly Ingenuity "no earlier than" April 19th at about 3:30AM Eastern. Don't worry about staying up all night to follow along, though. A livestream covering the data download won't start until 6:15AM Eastern if all goes smoothly, and the post-flight briefing isn't slated until 2PM Eastern.

The mission team had originally hoped to fly Ingenuity on April 11th, but a command sequence problem on April 9th led it to push the flight back. NASA just recently completed a spin test for the helicopter.

The flight will only be a 30-second hover meant to verify that the aircraft can fly in the first place. You'll have to wait until the four successor flights to see it roam the Mars surface. Even so, it will represent a historic moment if all goes according to plan. It's not surprising that NASA is cautious as a result — there's a lot riding on this mission besides the fate of a small drone.

NASA Selects SpaceX to Build Upcoming Lunar Lander




Space記事からです。 SpaceX Projectが 来るべき月着陸の計画にNASAにより選ばれる事となりました。




SpaceX has won a lucrative NASA contract to build the first lunar lander since the Apollo program. The announcement comes as a big surprise, as the Elon Musk-led company beat out a pair of promising competitors, including Jeff Bezos’s Blue Origin.

Sorry Blue Origin and Dynetics, but SpaceX will have the privilege of putting its logo on the next Moon lander, as NASA announced at a press conference today. The move highlights NASA’s growing trust in its commercial partner, as the space agency prepares to return astronauts to the Moon for the first time since 1972.

“This is a gutsy, and risky, choice by NASA,” Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, told me via Twitter. “If Starship works as planned, it will provide a lot more capability than the other entrants. But that’s a significant if.”

Plastic Is Falling From the Sky. But Where’s It Coming From?



At any given time, 1,100 tons of microplastic are floating over the western US. New modeling shows the surprising sources of the nefarious pollutant.






IF YOU FIND yourself in some secluded spot in the American West—maybe Yellowstone, or the deserts of Utah, or the forests of Oregon—take a deep breath and get some fresh air along with some microplastic. According to new modeling, 1,100 tons of it is currently floating above the western US. The stuff is falling out of the sky, tainting the most remote corners of North America—and the world. As I’ve said before, plastic rain is the new acid rain.

But where is it all coming from? You’d think it’d be arising from nearby cities—western metropolises like Denver and Salt Lake City. But new modeling published yesterday in the Proceedings of the National Academy of Sciences shows that 84 percent of airborne microplastics in the American West actually comes from the roads outside of major cities. Another 11 percent could be blowing all the way in from the ocean. (The researchers who built the model reckon that microplastic particles stay airborne for nearly a week, and that’s more than enough time for them to cross continents and oceans.)

Microplastics—particles smaller than 5 millimeters—come from a number of sources. Plastic bags and bottles released into the environment break down into smaller and smaller bits. Your washing machine is another major source: When you launder synthetic clothing, tiny microfibers slough off and get flushed to a wastewater treatment plant. That facility filters out some of the microfibers, trapping them in “sludge,” the treated human waste that’s then applied to agricultural fields as fertilizer. That loads the soil with microplastic. A wastewater plant will then flush the remaining microfibers out to sea in the treated water. This has been happening for decades, and because plastics disintegrate but don’t ever really disappear, the amount in the ocean has been skyrocketing.
