Gateway pipeline, proposed as an alternative to
Keystone XL, would connect Canada's oil sands to the Pacific Coast, allowing
greater volumes of oil to be shipped to Asia, but it, too, is still on the
drawing board.

Both are good examples of how pipelines - considered the safest way to move
oil and gas - have become politicized and scrutinized, and not without reason.
Despite their reliability, pipelines still lead to an unacceptable rate of
safety mishaps. They corrode and rupture, which threatens workers and nearby
communities. In 2013
alone, over 119,000 barrels of oil were spilled in 623 incidents.

America's existing pipelines are getting older and more prone to corrosion,
and over the next five to 10 years, there will be a significant increase in
the number of new pipelines.

And that is creating a huge opportunity for better pipelinePlacing a geosynchronous satellite into orbit typically involves three principal mission phases. First the satellite is placed in low earth orbit not far above the earth's atmosphere, either as part of the payload of a space shuttle vehicle or on a conventional non-reusable rocket vehicle. In the second phase, the satellite orbit has its apogee or highest point raised in altitude by one or more rocket "burns" at a selected point in the orbit, until the apogee is approximately at geosynchronous altitude. Finally, the satellite is given an apogee "kick," i.e. a further rocket burn at apogee that circularizes the orbit at geosynchronous altitude.
Once in orbit, rocket engines are called upon for three additional functions: station keeping, station changes and attitude control, which are sometimes referred to collectively
