Environmental concerns challenge states’ space ambitions

Read the full story at Stateline.

Some local leaders are proposing or helping to finance plans to establish spaceports in their regions, hoping to cash in on the economic potential. Some states even have established space-focused agencies, tasked with supporting the industry’s development.

But as spaceport proposals proliferate in places including Georgia, Maine and Michigan—far away from long-established federal launch sites in California and Florida⁠—they’re drawing pushback over fears they could harm sensitive habitats, public safety and even drinking water. Critics warn that the noise and light generated by launch sites could harm wildlife, and failed launches could spread toxic materials and debris or even cause wildfires.

Aviation giant KLM to face legal action in first major challenge to airline industry ‘greenwashing’

Read the full story at CNBC.

Environmental groups argue that KLM’s advertising campaigns and “compensation” schemes violate European consumer law by giving a false impression about the sustainability of its flights and its plans to tackle climate breakdown. The case is thought to be the first corporate lawsuit about airlines and net zero — and one of the first cases about carbon offsets. As a result, it has effectively put the global aviation sector on notice.

Scientists develop environmentally safe, frost-resistant coatings

Read the full story from the University of Illinois Chicago.

Airports are busy, especially during the winter. As passengers wait to board, delays get longer when airplanes need to be dowsed with thousands of gallons of deicing fluids that help them fight the frigid winter. But as soon as the plane takes off, most of the liquid is gone from the surface of the aircraft and ends up polluting freshwater streams and lakes.

In an endeavor to make a more efficient product immune to ice for such demanding industries and consumers, Sushant Anand, UIC assistant professor of mechanical engineering, and Rukmava Chatterjee, a UIC Ph.D. student, have developed a longer-lasting alternative to conventional deicers. They say it could also benefit other industries.

Biofuels are taking off with the airline industry on board
