NASA's involvement with fuel cell technology began in the 1960s, a time when fossil fuels dominated energy production. Fuel cells create electricity and heat through the combination of hydrogen and oxygen via an electrolyte, producing only water as a by-product, making them an environmentally friendly power source.
NASA's interest in fuel cells arose from the need to power Moon missions. E Scientists Advocate Major Study on Geoengineering for Glaciers

Wednesday, 17 July 2024 16:59
The Higgs boson, discovered over a decade ago in the Large Hadron Collider (LHC) detectors, remains elusive, with its properties still not fully understood. Recent progress comes from a collaboration between the Institute of Nuclear Physics of the Polish Academy of Sciences (IFJ PAN), RWTH Aachen University, and the Max Planck Institute for Physics, providing new insights into its origins. Spin Centers Propel Quantum Computing Forward
Wednesday, 17 July 2024 16:59
Quantum computing, harnessing the principles of quantum mechanics, is set to revolutionize fields such as medicine and machine learning by tackling problems too complex for classical computers. Quantum simulators, which consist of interacting quantum units, can be programmed to emulate intricate physical models, allowing scientists to extract valuable insights by controlling and measuring the in Tachyons Redefine Theoretical Boundaries in Modern Physics
Wednesday, 17 July 2024 16:59
Tachyons are hypothetical particles that exceed the speed of light. Often considered the "enfant terrible" of modern physics, these superluminal particles were previously thought to be incompatible with the special theory of relativity. However, a recent paper in Physical Review D by physicists from the University of Warsaw and the University of Oxford reveals that such assumptions were unfounde Three-Dimensional Acoustic Quantum Hall Effect Demonstrated in New Study
Wednesday, 17 July 2024 16:59
The quantum Hall effect (QHE) stands as a significant milestone in condensed matter physics, paving the way for advancements in topological physics. Extending QHE into three dimensions, however, presents substantial challenges. The primary difficulty lies in the extension of Landau levels into bands along the magnetic field direction, preventing the formation of bulk gaps.

A meteor streaked across the NYC skyline before disintegrating over New Jersey
Wednesday, 17 July 2024 16:00
A meteor streaked across the New York City skyline before disintegrating over nearby New Jersey, according to NASA.
William Cooke, the head of the space agency's Meteoroid Environments Office, said the fireball was first sighted at an altitude of 51 miles (82 kilometers) above Manhattan at around 11:17 a.m. Tuesday.
The meteor passed over the southern part of Newark, New Jersey, before disintegrating 31 miles (50 kilometers) above the town of Mountainside, he said. No meteorites or other fragments of space debris reached the planet's surface.
The space rock moved at a speed of about 41,000 mph (66,000 kph) and descended at a relatively steep angle of 44 degrees from vertical, Cooke said.
Its exact trajectory is uncertain, since reports are based only on eyewitness accounts and no camera or satellite data is currently available, he said.
As of Wednesday morning, there had been approximately 40 eyewitness reports filed on the American Meteor Society website, which the agency used to generate its estimates, Cooke said.
The fireball was not part of the Perseid meteor shower, and reports of loud booms and shaking could be explained by military aircraft in the vicinity around the time of its appearance, he said.

Lunar leap: GNSS-powered autonomous navigation for moon-bound spacecraft
Wednesday, 17 July 2024 15:24
As lunar missions gain momentum, the demand for advanced navigation technologies that exceed traditional Earth-based systems grows. A new study addresses the challenges of weak Global Navigation Satellite System (GNSS) signals and spacecraft maneuvers in the lunar space, emphasizing the need for sophisticated integrated navigation systems.
Combining GNSS, Inertial Navigation System (INS), and star trackers, this research paves the way for enhanced accuracy and stability in space navigation, essential for the success of future space exploration.
Researchers from Shandong University, in collaboration with the Shandong Key Laboratory of Optical Astronomy and Solar-Terrestrial Environment, have published the study in Satellite Navigation on July 1, 2024.
