Weekends on the International Space Station are for housecleaning and haircuts. NASA astronaut Jessica Meir trims the hair of fellow NASA astronaut Jack Hathaway, both Expedition 74 flight engineers, using an electric razor attached to a vacuum that collects loose clippings to keep the station’s atmosphere clean in microgravity.

The planet Mercury is the closest planet to the sun, and also the most difficult for spacecraft to visit and explore. This is because as spacecraft get closer to Mercury, the sun’s enormous gravity pulls in the spacecraft, greatly increasing its speed and making it hard to slow down without large amounts of fuel. But what if a spacecraft could both travel to and explore Mercury without fuel? This could drastically reduce mission costs while delivering impactful science.
Thousands of endangered species in British Columbia are not receiving the help they need to survive, according to new Simon Fraser University research. B.C. is Canada’s most biodiverse province, but analysis of nearly 20 years of data indicates that very few of its threatened species are showing signs of recovery, largely due to a lack of legislative protection.
