With over 100 active wildfires burning in Canada, wildfire smoke has drifted across the border into the United States, prompting Minnesota officials to issue the state’s first air quality alert of 2024.

At least 37 of the 141 active fires burning in Canadian wildfires have been labeled “out of control,” including one that started on Friday in British Columbia and has since spread to 4,200 acres, forcing the evacuation of the small town of Fort Nelson, and the Fort Nelson Indian Reserve, officials said.

Most of the active wildfires, at least 90, are in British Columbia and Alberta provinces.

How will liquids boil under reduced gravity, specifically on the Moon and Mars? This is what a recent project hopes to address as a team of researchers led by the Southwest Research Institute (SwRI) and working with Texas A&M University investigated the behavior of boiling liquids under reduced gravity using parabolic flights that are designed to simulate reduced gravity conditions. This project holds the potential to help researchers and future astronauts better understand how to manage boiling liquids during long-term space missions to the Moon and Mars where the gravity is one-sixth and one-third of the Earth’s, respectively.

“We have so little data about how boiling works in reduced gravity,” said Kevin Supak, who is a program manager at SwRI and the project lead. “Our experiment studies boiling in conditions that simulate lunar and Martian gravity levels using four different surfaces to examine how bubbles initiate and detach.”
