How do satellites not crash into each other?
Space and AstronomyThe aerodynamic drag on small satellites in Low Earth orbit can be used to change orbits slightly to avoid debris collisions by changing the surface area exposed to atmospheric drag, alternating between low-drag and high-drag configurations to control deceleration. How do satellites not run into each other? Satellite Collisions are rare because when a satellite

Can you reach the edge of the universe?
Space and AstronomyCan we go to the edge of the universe? As far as we can tell, there is no edge to the universe. Space spreads out infinitely in all directions. Furthermore, galaxies fill all of the space through-out the entire infinite universe. This conclusion is reached by logically combining two observations. What is over the edge

What does the Sun have in it?
Space and AstronomyInstead, the sun is composed of layers made up almost entirely of hydrogen and helium. These gases carry out different functions in each layer, and the sun’s layers are measured by their percentage of the sun’s total radius. The sun is permeated and somewhat controlled by a magnetic field. What does the sun contain? Abundance

Can you use a telescope as a microscope?
Space and AstronomyTherefore a telescope cannot work as a microscope. There is significant atmospheric distortion to be overcome by even the largest telescopes even if they are high in the mountains of Hawaii or the Andes. That distortion is gone completely by using space telescopes even though they are much smaller. Can we use a telescope as

Why is topology important in GIS?
Space and AstronomyWhy topology? Topology has long been a key GIS requirement for data management and integrity. In general, a topological data model manages spatial relationships by representing spatial objects (point, line, and area features) as an underlying graph of topological primitives—nodes, faces, and edges. What are the advantages of topology in GIS? Over the past two

What time can I see the eclipse?
Space and AstronomyThe first location to see the partial solar eclipse begin is at 1.45 p.m. EST (18:45 UTC), the greatest point of total solar eclipse occurs at 3.41 p.m. EST (20:41 UTC) and the last location to see the partial eclipse end is at 5.37 p.m. EST (22:37 UTC) according to Time and Date. What time

How do you graph a parallelogram?
Space and AstronomyTo graph parallelograms: Plot the coordinates of each point. Label each point with the corresponding letter. Connect the points in the order they are given. Use the graph to find the length of the sides, or the slope of the sides to show it is a parallelogram. How do you find the sides of a

Where are HaPe products made?
Space and AstronomyHape buys materials globally and sells to over 100 countries and regions. Locating the Hape factory only 3km from the Beilun Harbor, one of the largest ports in the world, created transportation as well as ecological advantages. Are Hape toys made in Germany? While Hape makes high-quality wooden toys that will last for years, their

What happened in the book hidden figures?
Space and AstronomyThe biographical text follows the lives of Katherine Johnson, Dorothy Vaughan, and Mary Jackson, three mathematicians who worked as computers (then a job description) at NACA and NASA, during the space race. They overcame discrimination there, as women and as African Americans. What happens in the end of Hidden Figures book? Eventually, the West Area
