For four decades, a quiet boundary in pure mathematics kept a powerful theorem locked inside the safe world of finite quantities. Now a new result known as Sebestyen’s theorem has pushed that boundary ...

Perhaps the most beautiful aspect of mathematics is that it applies to literally everything, even things that do not exist in ...

Artificial intelligence is everywhere. In fact, each reader of this article could have multiple AI apps operating on the very ...

Autonomous free-flying robots aboard the International Space Station (ISS) frequently lose their bearings. Without gravity to distinguish up from down, even precision sensors suffer from accumulating ...

Abstract: In this paper, a novel space vector pulse width modulation (SVPWM) technique with duty cycle optimization through zero vectors for dual three-phase (3-ph) permanent magnet synchronous ...

General Chance Saltzman’s newly released Vector 2025 is the clearest articulation yet of the U.S. Space Force’s purpose, priorities, and philosophy. It captures the seriousness of today’s contested ...

The U.S. Space Force has released Vector 2025, a consolidated reference outlining the direction and momentum the service intends to maintain as it continues its transition into a warfighting ...

The timing could not be more consequential as America sharpens its space posture while a mysterious interstellar visitor approaches our planet. [Photo credit: U.S. Space Force] What we know today sets ...

Space vector modulation (SVM) is a sophisticated digital control technique that improves three-phase inverter performance over traditional sinusoidal PWM (SPWM). SVM’s higher DC bus utilization ...

Can international cooperation keep space peaceful? We examine the challenges and opportunities for safeguarding space security. The 1960s were a landmark decade for space exploration, featuring ...
