Pat Galea explained to Discovery News in 2012. "The transmitter power on Icarus could be ramped down to much lower levels without impacting the available data rate, or if the power is kept the same, we could be receiving much more data than a direct link would provide." Ingenious as it might seem, however, the scheme also has some Jupiter-sized complications. Future advancements could include the use of satellite networks across the solar system, the use of laser technology for data transmission and the development of a space-adapted internet protocol to improve efficiency and reliability. But researchers have come up with an intriguing solution, according to the NASA's Space Technology Program Web site, which underwrites that sort of problem solving. Inside our solar system, the distances are so great that easy, instantaneous back-and-forth communication of the sort that we're accustomed to on Earth -- a Skype-style video conversation, for example -- isn't really feasible, at least with present technology. The communications craft would then use the sun as a lens to magnify the signals it gets from the distant starship, and then would transmit them back to Earth though some other system, such as a network of satellites with laser links.

But back on Earth, those monitoring the mission would still face the challenge of trying to pick up signals from the starship and filter out the ambient electromagnetic noise of space -- a task made even more difficult by the Earth's atmosphere, which would weaken the signals. The antennas in such an array would work in synergy to spot and capture the faint signals containing starship messages. That's why visionaries long have been intrigued with the idea of transmitting messages via beams of subatomic particle that would travel faster than light. They came up with one intriguing solution: Along the way, the massive ship would periodically jettison empty fuel canisters equipped with signal relay equipment, forming a chain that would pass back messages from the spacecraft to Earth. There was one highly-publicized 2011 experiment, in which researchers at the CERN particle accelerator in Europe supposedly clocked particles called neutrinos moving an extremely tiny bit faster than Einstein's speed limit. But guess again. For that scheme to work, we seemingly would have to blow a great big hole in Einstein's theory of special relativity, which prohibits anything from moving faster than light speed. According to Einstein's relativity theories, extremely massive objects' gravitational forces can actually deflect light that's passing near them and concentrate it, the way a hand-held magnifying glass does.

But if those dissenters turn out to be right, we'd still have to actually find some proof that particles can move faster than light speed, and so far we haven't. Satellites normally orbit planets in Keplerian orbits, named after the 17th century astronomer Johannes Kepler, who wrote the mathematically equations that describe how satellites move. The notion of, say, sending live, streaming video from Mars to Earth may not seem that far-out to a member of the millennial generation, who grew up in an age when having a cell phone conversation with someone on the other side of the planet is no big deal. Instead of sending out a single signal or pulse of energy, a spaceship trying to communicate with Earth would send out many copies of that signal, all at once. Picking out that mind-bogglingly faint signal from the irrepressible cacophony of space and making sense of it might be as difficult as, say, finding a message floating in a bottle somewhere in the Earth's oceans. The vast distances, motion of planets and space radiation pose significant challenges, creating lag times and signal degradation that complicate communication across space.

And if we're going to travel to planets outside our solar system, it would become pretty much impossible. DBS can also be used on brain regions outside the basal ganglia to treat other conditions caused by abnormal brain function. The squeaks and hisses of the connection handshake are forever embedded in my brain. By altering the behavior of the STN, the electrode is ultimately altering all of the brain activity that the STN normally affects. Consider the future - Before you spend valuable resources changing a bedroom into a home theater, consider the problems a big structural retrofit will cause when you go to sell your home in a few years. Only a few machinimists have sold films to the public, and in those cases the filmmakers secured permission from the respective game company before going forward. I got a little shock a few years back, when I contacted a source for an article by e-mail, and got a call back from him -- via Skype -- from Afghanistan, where he had traveled for a business project.
