NASA’s first new wind tunnel in 40 years will turn science fiction to fact

Posted by in categories: military, space

Flying cars. Space tourism. Safe reentry for astronauts coming back from Mars.

These technologies are still , but some won’t be for much longer, according to Charles “Mike” Fremaux, NASA Langley Research Center’s chief engineer for intelligent flight systems.

To test these concepts, particularly in regard to public and military safety, NASA Langley is building its first new wind in over 40 years. The NASA Flight Dynamic Research Facility, a project Fremaux has been pursuing for 25 years, will replace two smaller wind tunnels that are around 80 years old. The center’s most recent and largest, the National Transonic Facility, was built in 1980.

Researchers use AI to help simulate and predict solar events

Posted by in categories: robotics/AI, space

This could help us improve our understanding of the Sun and its impact on space weather.

A collaborative effort between researchers at the University of Graz in Austria and the Skolkovo Institute of Science and Technology (Skoltech) in Russia used artificial intelligence (AI) to study the magnetic field in the upper atmosphere of the Sun, a press release said.

The solar magnetic field is a poorly understood area of research among astronomers. Even after centuries of watching the Sun, we only have limited information about how sunspots are formed or whether they will lead to events like a flare or a coronal mass ejection (CME).

This underwater base could become the ISS of the ocean

Posted by in categories: climatology, space, sustainability

2020 underwater base.

Aquanaut Fabien Cousteau — grandson of famed ocean explorer Jacques-Yves Cousteau — has announced plans to build the world’s biggest underwater base for scientific research.

He calls the facility “Proteus” and envisions it being the ocean equivalent of the International Space Station — a place where scientists from across the globe can work together to solve the world’s biggest problems, from climate change to world hunger.

Trio of Orion spacecraft prepped for NASA moon missions

Posted by in category: space

NASA has shared an image of three spacecraft that will play a central role in its next three Artemis missions to the moon.

Having already successfully tested the Orion spacecraft on a lunar flyby at the end of last year after being blasted to space by NASA’s new Space Launch System rocket, the American space agency is now overseeing the building of three more Orion capsules for upcoming Artemis missions.

Why scientists think life once thrived on the hell planet Venus

Posted by in category: space

Venus is one of the most brutally inhospitable places in our solar system, but many scientists think life may have thrived there at one point. Here’s why.

Challenging Conventional Wisdom: New Discovery Transforms Our Understanding of Crystals

Posted by in categories: engineering, nanotechnology, particle physics, space

For many, the word “crystals” conjures images of shimmering suncatchers that create a prism of rainbow colors or semi-transparent stones thought to possess healing abilities. But in the realm of science and engineering, crystals take on a more technical definition. They’re perceived as materials whose components – be it atoms, molecules, or nanoparticles –are arranged regularly in space. In other words, crystals are defined by the regular arrangement of their constituents. Familiar examples include diamonds, table salt, and sugar cubes.

Astronomers identify the coldest star yet that emits radio waves

Posted by in categories: energy, space

Astronomers at the University of Sydney have shown that a small, faint star is the coldest on record to produce emission at radio wavelength.

The ‘ultracool brown dwarf’ examined in the study is a ball of gas simmering at about 425 degrees centigrade—cooler than a typical campfire—without burning .

By contrast, the surface temperature of the sun, a nuclear inferno, is about 5,600 degrees.

India moon mission rocket blasts into space — BBC News

Posted by in categories: government, space

India has launched its third Moon mission and is hoping to become to the first to land near its south pole – which has rarely been explored.

If successful, the Chandrayaan-3’s orbiter, lander and a rover are due to touch down on the Moon’s surface on 23 or 24 August.
