The permissible degree of eccentricity can be expressed by a plus and minus wall thickness tolerance. If you have any comments or questions about the glossary, please contact Dan Davis, ...

The U.S. military's top-secret X-37B space plane has returned from a mysterious 434-day mission in orbit. The enigmatic mission 'broke new ground' for reusable space technology, according to the U ...

Evapotranspiration (ET) has considerable significance in the water cycle, especially in farming areas where it determines crop water needs, irrigation plans, and sustainable management of water ...

The 20th launch took to the skies during Sunday night's Oscars ceremony, as SpaceX sent up another payload of 21 Starlink broadband satellites into low-Earth orbit from Cape Canaveral Space Force ...

then compared this data to the Earth's oval-shaped orbit around the sun, a phenomenon called orbital eccentricity. The authors found each glaciation period in the last 900,000 years followed a ...

The Falcon 9's upper stage, meanwhile, continued its ascent to orbit, where it deployed the 21 Starlink satellites about 65 minutes after liftoff as planned. The new batch of Starlinks adds to ...

"Athena continues to be in excellent health and is expected to send lunar orbit selfies over the next two days before a landing attempt on March 6." Intuitive Machines' second lunar lander has ...

We consider the radius of the Earth to be 6,371,000 meters. In particular, it is proposed to simulate with an orbit altitude equal to 300,000 meters with an eccentricity of 0.0002, with polar orbit, ...

It has a somewhat oval shape referred to as orbital eccentricity, with the Sun off-center in the oval, which means Earth's distance from the Sun changes throughout the year. And the position of that ...

After 18 months of eye-in-the-sky secrecy, Chinese scientists have revealed the revolutionary technology behind the world’s first geosynchronous orbit synthetic aperture radar (SAR) satellite ...

Researchers have identified the key roles of precession, obliquity, and eccentricity, which influence the tilt of Earth’s axis, its wobble, and the shape of its orbit around the Sun. These factors, ...
