How is it possible for the ISS to stay in orbit? Learn more about the science behind orbiting Earth and more in this NASA ...
Researchers in Spain reviewed six models used to calculate incidence angle modifier (IAM) losses in photovoltaic systems. They identified the Martín-Ruiz model as the most comprehensive, as it ...
A rediscovered formula is changing how we understand the hidden journeys of airborne particles. Researchers at the University of Warwick have created a straightforward new way to predict how ...

Velocity rules in October when adrenaline, pressure, crowds push players to throw their hardest
Velocity rules in October. There have been a record 255 pitches of 100 mph or faster this postseason, up from 105 last year and the previous high of 169 in 2022. Right-handed ...
Abstract: Since vision-based sensors typically cannot directly measure the relative linear and angular velocities between two spacecraft, it is useful to develop attitude- and position-tracking ...
When an object is falling, the two main forces acting on it are weight close weightA force that acts on mass, pulling it down, due to gravity. Weight is a force and forces are measured in newtons (N).
Is something happening in our solar system? An object from interstellar space, designated 3I/ATLAS, is not just passing ...
We measure the “warmness” of the dark matter, i.e. the comoving root-mean-square thermal velocity v hrms (1) , with nearly 3000 spiral galaxy rotation curves in the ...
Abstract: In this brief, a global finite-time attitude control algorithm is proposed for flexible spacecraft without angular velocity measurement. First, a global finite-time observer is designed to ...
