With the fast development of low earth orbit (LEO) enhanced global navigation satellite system (LeGNSS), there is huge demand in LEO real-time precise orbit determination. Real-time service from ...

The science behind why the Earth will spin just a little bit faster on July 9, July 22, and August 5, this year.

A new initial orbit determination (IOD) method using single-site very short arc radar observations is proposed. The method uses slant range, azimuth, and elevation angles to determine the position ...

Here’s what to expect from Project Kuiper’s first full-scale satellite launch United Launch Alliance will send 27 Kuiper satellites into low Earth orbit as we begin a full-scale deployment of our ...

Japan's H-2A rocket, built for JAXA by Mitsubishi Heavy Industries, was capable of launching payloads into a geostationary orbit around Earth and to orbit around the moon.

In an era where the geometry of power is tilting skyward, the nations with eyes in orbit will be the ones that define what comes next.

Is It True Earth Used To Take 420 Days To Orbit The Sun? You might have seen the claim online, and it’s at least partially right, but it's not the only other number of days Earth has had.

What if the Earth rotated so fast that the ISS was in a geostationary orbit just 400 kilometers above the surface? That might make the space elevator possible.

Asteroid 2023 JF flew about 199,000 miles (320,000 km) away from Earth. It's estimated size is about 34 feet wide (10 meters), roughly the size of a bus. Orbit animation courtesy: NASA/JPL-Caltech ...

Earth’s oldest rocks may be at least 4.16 billion years old An unconventional dating method aims to settle a dispute over the age of some Canadian rocks ...

Scientists have identified what could be the oldest rocks on Earth from a rock formation in Canada.

New simulations reveal that the infamous "city killer" asteroid 2024 YR4 could shower Earth with "bullet-like" debris if it hits the moon in seven years' time, potentially triggering an eye ...
