The ESA is about to turn one of its spacecraft into a fireball

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

Next week, the European Space Agency is going to jettison a cubesat called Qarman from the International Space Station and watch it burst into a fireball as it reenters Earth’s atmosphere—all on purpose.

What’s the mission: Qarman (short for “QubeSat for Aerothermodynamic Research and Measurements on Ablation”) is a shoebox-sized experiment meant to help researchers better understand the physics at play when objects plummet into the planet’s atmosphere and burn up. Qarman was brought up to the ISS in December during a cargo resupply mission. On February 17, it will be cast back out into space and begin slowly drifting toward Earth before entering the atmosphere and burning up in about six months.

Tell me more: Qarman has four solar-cell-covered panels that are designed to increase atmospheric drag and hasten reentry. Its nose is made from a special kind of cork that’s typically used in thermal protection systems on spacecraft. Ground testing shows that when the cork heats up, it chars and flakes away a bit at a time. The Qarman team is interested in learning how this process works during reentry.

8 Year-Old Mexican Girl Invents A Solar Water Heater & Wins Nuclear Science Prize

Posted by in categories: nuclear energy, robotics/AI, science, sustainability

Innovation comes from all ages, and this is further seen in the story of Xóchitl Guadalupe Cruz, an eight-year-old girl from Chiapas, Mexico who invented an entirely solar-powered device for heating water. The impact her invention could have on others around the world is immense, and this has inspired the UNAM’s (National Autonomous University of Mexico) Institute of Nuclear Sciences to award her.

To those in developed countries, her invention may not seem all that revolutionary as access to warm or hot water is commonplace, but for those in many other areas of the world, including her town in Mexico, this would be a luxury.

Antidepressant Microbes In Soil: How Soil Makes Your Brain Happy

Posted by in categories: biological, food, neuroscience, sustainability

Antidepressant-soil.


Soil microbes have been found to have similar effects on the brain as prozac, without the negative side effects and potential for chemical dependency and withdrawal.

It turns out getting in the garden and getting dirty is a natural antidepressant due to unique microbes in healthy organic soil. Working and playing in soil can actually make you happier and healthier.

Plastic Eating Plants: Will they Save our Environment?

Posted by in categories: biological, food, particle physics, sustainability

Circa 2016 o.o


Americans dump 251 million tons of trash annually into landfills. Bike seat ripped? Toss it. Hole in the old garden hose? Get rid of it. Spandex not tucking in your tummy? Loose it and replace it. This linear process of extracting a resource, processing it, selling it than discarding it is creating a mound of trash dangerously equivocal to the ball of trash in Futurama episode 8 season 1.

Congress Proposes Nationwide Network of Electric Car Chargers

Posted by in categories: government, sustainability, transportation

Representatives Alexandria Ocasio-Cortez and Andy Levin have introduced a new bill that would build a national infrastructure for electric vehicles.

The EV Freedom Act would allocate the resources for the U.S. to build a nationwide network of electric vehicle chargers within five years, Reuters reports. That would alleviate a major hurdle to widespread electric car adoption, making it far easier for the population to transition away from gas power.

Cuba’s rivers run clean after decades of sustainable farming

Posted by in categories: food, health, sustainability

Thoughts?


Despite centuries of colonization and agriculture, Cuba’s rivers are in good health.

Sugarcane and cattle farming on the island date back to the late fifteenth century. To measure water quality in Cuba’s rivers today, Paul Bierman at the University of Vermont in Burlington, Rita Hernández at the Cienfuegos Center for Environmental Studies in Cuba and their colleagues sampled water in 25 river basins in central Cuba. This is the first time in more than 60 years that scientists from Cuba and the United States have joined forces to study the island’s hydrology.
