The origin of water on Earth is not yet fully understood. To test one of the hypotheses, scientists launched a gigantic observational balloon to the height of almost 130,000 feet to measure the amounts of water in comets and asteroids based on the light reflected from these objects. The science BEST SUITED to calculating the forces required to launch the balloon to the required altitude is Physics Which physical science is the BEST to study the composition of Earth's atmosphere? Earth ...

Geostationary Satellites (Goes) Stationary with respect to a fixed point on Earth's surface (revolves at the same rate as Earth) -Far from earth (36,000 km) = coarse spatial resolution, but good temporal sampling. Visible satellite appears black where the sun is not hitting earth. See lots of black Infrared satellite shows a picture of the whole earth- also shows white around the whole earth. reads the surrounding temp of earth, so the universe is cold, shoing white. ...
