“Researchers at the University of California, Berkeley, have found a new way to harness properties of light waves that can radically increase the amount of data they carry. They demonstrated the emission of discrete twisting laser beams from antennas made …
“Previous NASA Mars rovers mostly used an operating system from Wind River Systems. But this time, the space agency chose Linux for Perseverance’s Ingenuity helicopter drone. When NASA’s Perseverance rover landed on Mars this week, it also brought …
“The huge parachute used by NASA’s Perseverance rover to land on Mars contained a secret message, thanks to a puzzle-lover on the spacecraft team — and space lovers solved it within hours. Engineers wanted an unusual pattern in the orange …
“Expansion of SA50-120 family introduces qualified 100V and 120V bus systems for space applications As reliance on communication and weather satellites grows and space research expands in scope and mission, new technology is required to help speed spaceflight system …
“Starlink broadband speeds will double to 300Mbps “later this year,” SpaceX CEO Elon Musk wrote on Twitter yesterday. SpaceX has been telling users to expect speeds of 50Mbps to 150Mbps since the beta began a few months ago. Musk also …
News NASA’s Mars Perseverance Rover Provides Front-Row Seat to Landing, First Audio Recording of Red Planet
“New video from NASA’s Mars 2020 Perseverance rover chronicles major milestones during the final minutes of its entry, descent, and landing (EDL) on the Red Planet on Feb. 18 as the spacecraft plummeted, parachuted, and rocketed toward the surface …
News NASA’s Webb Telescope Will Show Us More Stars at Higher Resolution—Here’s What That Means for Astronomy
“The combination of high resolution and infrared-detecting instruments on NASA’s upcoming James Webb Space Telescope will reveal stars that are currently hidden even from the powerful Hubble Space Telescope. The wealth of additional star data will allow astronomers to …
“Asymmetry in the proton confounds physicists, but a new discovery may bring back old theories to explain it. Symmetry — displayed in areas ranging from mathematics and art, to living organisms and galaxies — is an important underlying structure in nature. It …
News New Material is Next Step Toward Stable High-voltage Long-life Solid-state Sodium-ion Batteries
“A team of researchers designed and manufactured a new sodium-ion conductor for solid-state sodium-ion batteries that is stable when incorporated into higher-voltage oxide cathodes. This new solid electrolyte could dramatically improve the efficiency and lifespan of this class of batteries …
“The design may enable miniature zoom lenses for drones, cellphones, or night-vision goggles. Polished glass has been at the center of imaging systems for centuries. Their precise curvature enables lenses to focus light and produce sharp images, whether the object …
