New liquid nitrogen spray could help NASA solve its lunar dust problem
The novel method could form a crucial part of NASA’s plans to establish a permanent human presence on the moon.
You may not know that lunar dust poses a real problem to NASA as it aims to establish a permanent crew presence on the moon with its upcoming Artemis missions.
Now, though, a new liquid nitrogen spray developed by Washington State University researchers was able to remove virtually all of the simulated moon dust from a space suit during tests, a press statement reveals.

Moondust is largely made of small particles that can damage spacesuits, machinery, and equipment. In future habitats, it may even pose a health risk by damaging astronauts’ lungs.

Astronaut captures unreal aurora image from space station
A geomagnetic storm caused by a series of recent explosive events on the sun has brought spectacular auroras to parts of Earth in recent days.
Astronauts on the International Space Station (ISS) 250 miles above our planet have also been enjoying the amazing light show, with ISS inhabitant Josh Cassada sharing a stunning image that he captured just recently.
“Absolutely unreal,” Cassada tweeted alongside the image, which shows not only the gorgeous greens of the aurora, but also city lights on Earth, and part of the space station.
