There are actually two voltages: 28 volts direct current (DC) and 115 volts 400 hertz (Hz). The scientific and flying equipment on spacecraft use these special types of voltages—at least ... be replaced if it trips or blows. This means that if we use fuses we would have to carry spare fuses, and this means extra weight, which is not good.

... is very steady in orbit. Periodically, however, it must propel itself back up to the preferred operating altitude that gradually decreases because of the influence of the small amount of atmospheric gas in the 250-mile and immediately lower altitude region. And this adjustment is accompanied by ...

The surface temperature of the Sun is about 5800° Kelvin (K) or over 10,000° F. As one gets into the corona of the Sun, the temperatures can reach many millions of degrees K The Kelvin ... to this temperature as absolute 0, where there is virtually no molecular movement or energy expended by molecules. Today, the Celsius or Centigrade (C) scale references the Kelvin scale in such a way that 0 ...
... from the propellant and its exhaust velocity. The maximum, or ideal, velocity that can be obtained by a single stage rocket is roughly twice the exhaust velocity, depending on the ratio of the fuel mass to the total vehicle mass (this mass ratio is called the ...
... either the Moon or Mars rovers. It is an important fact that the farther away a robot has to travel, the lighter it should be. The lighter something is, the cheaper it is to send into space. The smallest is the American rover Sojourner, launched to Mars in 1997. It weighed only 23 pounds.
