160km. Once these conditions are defined, the rest of the orbit parameters are defined, in this case the orbital period was 103min, the inclination of the orbit was 99°, and an orbital height at the apogee (point in the orbit with the largest distance to the center of the Earth) of...

The International Space Station seen at a distance. (Image credit: NASA) At the moment, most of the ISS consortium has committed to operations until 2030, while Russia says it will stay until at least 2028. Russia is departing the consortium in the wake of the internationally condemned Ukraine...
The central-force-field equations reveal that NEO eccentricity and average solar distance are thereby slightly increased. Given decades of warning and long-lived reflective canopies, such structures can convert Earth-impacts into near-misses. Although not suitable for NEO mining, such structures are ...
The magnetopause distance rM can be estimated by equating the effective dynamic pressure of the solar wind (of mass density ρ, velocity V), ρV2, to the effective magnetic pressure (2B)2/2μ0, of the planet’s magnetic field at the magnetopause distance rM, with B=(μ0/4π)μ/rM3...
Clicking directly on the map to set the location, then adjusting the direction of view. Choosing peaks from a searchable list Entering the exact latitude/longitude, and also setting camera height, distance, viewing angles and more. As you adjust the position and parameters, you get a mini-prev...
1. The rate of fall (v) of a body increases proportionally to the time of fall (t). 2. The distance fallen (h) increases proportionally to the square of the time of fall (t). The body's mass or shape does not affect the fall distance or its fall speed. However, Galileo was wel...
these satellites are placed into orbit at a distance of around 35,800 km from the earth’s surface. they rotate in the same direction as the earth and one revolution of such satellites is the same as one day on earth (roughly 24 hours). this means that, as seen from earth, these ...
Earth has at least five co-orbital asteroids, including3753 Cruithneand2002 AA29. A trojan asteroid companion,2010 TK7, is librating around the leading Lagrange triangular point, L4, in the Earth's orbit around the Sun. The tiny near-Earth asteroid2006 RH120makes close approaches to the Eart...
At 11:05 a.m., the Dragon spacecraft will undock from the Harmony module’s forward port on the ISS. Ground controllers at SpaceX will then command the spacecraft to fire its thrusters, guiding it to a safe distance from the station. ...
