How is it possible for the ISS to stay in orbit? Learn more about the science behind orbiting Earth and more in this NASA "STEMonstrations" video. Credit: NASA Johnson Space Center Judge rules ...

The impact crater could be linked to the origins of life on Earth. The discovery of a massive crater formed by the impact of a meteorite more than three billion years ago is changing the way ...

The translational motion is described by the vehicle velocity vector and position with respect to the surface of the Earth. The rotational motion is described by the vehicle angular velocity vector ...

This paper investigates the use of gyroscope to estimate the attitude rate and inertia matrix for low earth orbit satellite via extended ... that the accuracy of the estimated inertia and angular ...

Angular velocity is a measure of how quickly an object rotates or revolves around a central point or axis. It is a vector quantity, meaning it has both a magnitude and a direction. Angular ...

Humanity's impact on the polar ice sheets is slowing Earth's rotation, posing a challenge for how it matches up with the official timekeeping. Humanity is rapidly waking up to the fact that time ...

"Even a tiny gravity vector is better ... the radius of its angular velocity, the faster it has to spin to achieve the equivalent of the gravitational force on the Earth's surface, or 1g.

Abstract: This letter presents a novel attitude estimation solution, built on $SO(3)$ , that resorts to single measurements of a constant inertial vector, in addition ...
