Earth orbit isn't so much "high" as "fast." The ISS routinely passes closer to my house than Los Angeles; it wouldn't be a terribly far commute. The only problem is that, if I were to travel in a straight line those 249 miles up to touch it, I would then simply be 249 miles above the ground, and what would happen next is technically known as "falling."
Originally shared by +Yonatan Zunger Things stay in orbit not by being high up, but by moving fast enough that they continually fall towards the ground and miss. Draw a line between yourself and the center of the Earth; gravity is pulling you along that line. Point your nose perpendicular to that line, and go: your normal straight-line motion is moving you away from the Earth. The art of orbiting is simply the art of keeping those two things in balance, so that you're moving so quickly through space that you're losing altitude through falling at the same speed that you're gaining it through hurtling. Of course, you have to be going kind of fast for this to work. The ISS travels at a steady speed of 7.6km (4.76 miles) per second. This is why spacecraft don't simply fly straight up; they fly up about 26,000' to get out of the thickest part of the air, then turn 90° and thrust for speed. (This post talks more about why that makes more sense than taking off horizontally like an airplane: https://plus.google.com/+YonatanZunger/posts/VsYyUDxFUDr) It probably won't surprise you that when you're flying at this speed, running into things is not a good […]
