... dependable, controllable, able to move spacecraft of all sizes, and we know how to build them. However, in the future we may learn to use the gravitational pull of bodies in the solar system to propel spacecraft. We might call this electromagnetic propulsion. Another possibility is the use of solar sails to propel ...
... faster. By the time it reaches space it is traveling at least 17,000 mph. We don't have to go a specific speed to leave the atmosphere, but we have to be traveling at a minimum of 17,000 mph in order to stay ...
... ways to create habitats and eventually cities in space and on the Moon and Mars. We understand the space environment well so we know how to design for living there safely. People from ...
Eventually there will be millions of people living in space, on the Moon and on Mars. In 50 years there may be enough people and biospheres (farms) that if something ...
Once a spacecraft achieves a typical low Earth orbit, the spacecraft can expect to see an orbital sunrise and sunset every 45 minutes.

... simple calculation is completed. There are some known facts: how fast we are going, how high we are, and where we want to land. This is an energy-versus-range calculation which determines ...
... up. If the re-entry is too shallow, the orbiter will skip, like a rock on water, off of the atmosphere. Both cases are very bad. An approximate safe entry attitude ...
... rocket propulsion nowadays, primarily because the energy content per pound is not as great as other fuels. For example, the energy of regular gasoline is about 18,500 British Thermal Units ...
... , as every object is floating. This includes the spacecraft and everything in it. The reason we float is that the force of gravity that pulls us to the Earth is exactly ...
