The Earth has one natural satellite: the moon. As of 2021 there are over 6500 artificial satellites, about half of them are active. This is an amazing number when before 1957 (65 years ago), there were none. Have you seen an artificial satellite in the night sky? Chances are you have if you're paying attention since there are so many and they can a...
An ephemeris is a table (or tables) giving the coordinates of a celestial body at a number of specific times during a given period. These were traditionally published in books and magazines, but these days there are various internet sites to give this information. And it's very personalized because you can input your exact location and various othe...
Constellation satellitesare groups of satellites that work together as a system. The reason for the many satellites is they can provide global (or near global) coverage. This means at any given time one or more of these satellites is in the local sky. The most famous of this type of satellites is Global Positioning System (GPS). The animation at th...
Geosynronus satellites are a very special class of satellites. They all orbit approximately 35,786 km (22,236 miles) along about our equator. This altitude is special because at this altitude, their orbital period (1436 minutes = one sideral day) matches Earth's rotation period and the satellites hover over the same spot as shown in the animation a...
Another problem is that from a size standpoint you'd like to have it pass directly overhead. However, directly overhead can be difficult to navigate with your telescope plus when at overhead or near overhead, the apparent speed of the ISS is the fastest. At 45°-60° the size is smaller, but the ISS is moving slower which makes it easier to track and...
Sep 28, 2021 · Astronomers estimate that, from a dark site, we see about 2,000 stars with the eye alone. And if we’re lucky, we might also see a satellite, or even two, crossing the sky. But, in the future, a...
May 9, 2016 · At their brightest, NOAA satellites have an apparent magnitude of +5.5, which is pretty faint. The apparent magnitude of an object describes how bright it appears in the sky from Earth. The brighter an object appears to us, the lower its magnitude value.
May 15, 2020 · Heavens-Above can show you predictions for many satellites. Recently, one company called SpaceX, has started launching hundreds of satellites into low altitude orbits. Each rocket launch from Florida in the USA holds about 60 satellites and will often pass overhead of us in the UK soon after launch.
Chapter Objectives. Upon completion of this chapter you will be able to describe the basic constituents of spacecraft navigation including the role of the mission reference trajectory, the need for orbit determination, and flight path control via propulsive maneuvers. You will be able to recognize four distinct Deep Space Network (DSN) data ...

A: Yes, heaven is a place of total happiness and peace, and we can be confident that our loved ones who have gone before us into heaven are not disturbed or upset over the evil things that happen here on earth. The Bible doesn’t clearly tell us if people in heaven are able to observe what happens on earth–although there are some hints that ...
