- 761: Our Solar System at a Glance
- ... to fulfill separate and specific mission objectives, the craft share much in common. Each spacecraft consists of various scientific instruments selected for a particular mission, supported by basic subsystems for electrical power, trajectory and orientation control, as well as for processing data and communicating with Earth. Electrical power is required to operate the spacecraft instruments and systems. NASA uses both solar energy from arrays of photovoltaic cells and small nuclear generators ... a planet, only to have its cameras and other sensing instruments pointed the wrong way as it speeds past the target! To help prevent such a mishap, a subsystem of small thrusters is used to control spacecraft. The thrusters are linked with devices that maintain a constant gaze at selected stars. Just as Earth's early seafarers used the stars to navigate the oceans, spacecraft use stars to maintain their bearings ... core larger, proportionally, than the Moon's core or those of any of the planets. After the initial Mercury encounter, Mariner 10 made two additional flybys -- on September 21, 1974, and March 16, 1975 -- before control gas used to orient the spacecraft was exhausted and the mission was concluded. Each flyby took place at the same local Mercury time when the identical half of the planet was illuminated; as a ...

One must control buoyancy carefully. When you are at the surface, you will want to be positively buoyant so that you could conserve energy while resting or swimming. Under water, you will want to be neutrally buoyant so ... that you are weightless and can stay off the bottom and avoid crushing or damaging delicate corals and other aquatic life. Neutral buoyancy permits a diver to move freely in all directions (Kolezer, 17). Buoyancy control is one of the most important skills that a diver could master, but it is also one of the easiest. A diver, controls his/her buoyancy using lead weight and a buoyancy control device (BCD). The lead weight, which is incorporated into a weight system, such as a weight belt is negatively buoyant.
