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.

Innovative 3D Telemedicine to Help Keep Astronauts Healthy

During almost two-years of the COVID-19 pandemic, the growth of telemedicine and new ways of reaching people has changed and developed. In October 2021, NASA flight surgeon Dr. Josef Schmid, industry partner AEXA Aerospace CEO Fernando De La Pena Llaca, and their teams were the first humans “holoported” from Earth into space.

Using the Microsoft Hololens Kinect camera and a personal computer with custom software from Aexa, ESA (European Space Agency) astronaut Thomas Pesquet had a two-way conversation with live images of Schmid and De La Pena placed in the middle of the International Space Station. This was the first holoportation handshake from Earth in space.

Holoportation is a type of capture technology that allows high-quality 3D models of people to be reconstructed, compressed and transmitted live anywhere in real time.

Finally spotted! JWST caught a 1.4 billion year old, metal-rich galaxy

The discovery has left astronomers at Cornell University in wonder.

Analyzing the data of the first image captured by NASA’s JWST (James Webb Space Telescope) of a popular early galaxy, astronomers at Cornell University were surprised by the blob of light shining near the galaxy’s outer edge.

While scanning the image, the initial focus and target of the infrared observatory was SPT0418-47, one of the brightest dusty, star-creating galaxies in the early universe. Its distant light bent and magnified into a circle (Einstein ring) by the gravity of a foreground galaxy.

30 years of NASA’s Magellan mission may finally solve how Venus cools

These peculiar geological structures could explain a long-standing mystery of how Venus loses its heat.

Given Venus and Earth are both rocky planets with roughly the same size and chemistry of their rocks, they should be losing their interior heat to space at a similar rate. How Earth loses its heat is well known, whereas Venus’ flow process remains a mystery.

How does Venus, the hottest planet in the solar system, lose its heat?

According to a news release from NASA, new research has taken a fresh look at how Venus cools using data from the NASA Magellan mission that spans three decades and discovered that thin parts of the planet’s uppermost layer might provide an answer.

Liquid nitrogen spray could clean up stubborn moon dust

A liquid nitrogen spray developed by Washington State University researchers can remove almost all of the simulated moon dust from a space suit, potentially solving what is a significant challenge for future moon-landing astronauts.

The sprayer removed more than 98% of moon dust simulant in a vacuum environment with minimal damage to spacesuits, performing better than any techniques that have been investigated previously. The researchers report on their work in the journal, Acta Astronautica.

While people have managed to put men on the moon, they haven’t figured out how to keep them clean there. Similar to the clingiest packaging peanuts, moon dust sticks to everything that it touches. Worse than the packing peanuts, the dust is composed of very fine particles that are the consistency of ground fiberglass.
