The orbital velocity of the satellite depends on its altitude above Earth. The nearer to Earth, the faster the required orbital velocity. At an altitude of 124 miles (200 kilometers), the required orbital veloc
NASA researchers have found that at 1 astronomical unit (AU), which is the distance from the sun to Earth, equal to 93 million miles (150 million km), sunlight can produce about 1.4 kilowatts (kw) of power. If you take 1.4 kw and divide it by the speed of light, you would find ...
To find the relationship between the orbital velocity of a satellite revolving close to the surface of a planet and the escape velocity of that planet, we can follow these steps: Step 1: Define Escape VelocityThe escape velocity (Ve) is the minimum velocity required for an object to escape ...
On February 8, 2022, approximately 40 of the 49 Starlink satellites were reported to have lost altitude, leading to atmospheric re-entry. SpaceX reported that the orbital decay on Starlink satellites was considered to be linked to a geomagnetic storm tha
In the industry, we call this a clear ‘line-of-sight’ to the satellite. Fortunately, finding if there is clear line of sight is is simplified by using a look angle calculator. All that’s needed is a current address (anywhere in the world), and the orbital longitude of the satellite...
After an eventful five days in space, which included the first-ever commercial spacewalk, the private astronaut crew of Polaris Dawn is returning to Earth. If all goes according to plan, the SpaceX Dragon capsule Resilience — orbital home to the four-person over the past five days — will...
GPS, or the Global Positioning System, is a global navigation satellite system that provides location, velocity and time synchronization. GPS is everywhere. You can find GPS systems in your car, your smartphone and your watch. GPS helps you get where you are going, from point A to point ...
How do you prepare to capture an image of the ISS? First, I usetransit-finder.comto find out where and when transits are visible within a radius of several hundreds of km around my home. I also have to consult the weather forecast during the days before the event, to assess the probab...
How do you calculate orbital distance? Orbiting Bodies: In many situations in space, bodies orbit around one another or one body about the other. Using our own solar system as his model, Johannes Kepler formulated three Laws of Planetary Motion with some being later refined by Newton for other...
positions made at the same time.Footnote1The spatial resolution of the series is determined by the ratio of the satellite speed to the sample rate of the underlying measurements’ time series, whereas the time resolution at a given point is determined by the revisit times of the satellites....
