Space Communication Quotes

A single message from space will show that it is possible to live through technological adolescence. . . . It is possible that the future of human civilization depends on the receipt of interstellar messages.

We all know the Internet didn't explode until it became a commercial enterprise. Space communication will probably have the same characteristic.

Roger, we copy. It was beautiful from here, Tranquility. Over.

You can only fit so many words in a postcard, only so many in a phone call, only so many into space before you forget that words are sometimes used for things other than filling emptiness.

I can conceive of no nightmare so terrifying as establishing communication with a so-called superior (or, if you wish, advanced) technology in outer space.

When ... we realize the possibilities of deep sea life still unknown to us, every haul of the dredge should be welcomed by an expectant enthusiasm equaled in other fields only by the possible hope of communication with our sister planets.

Alternate currents, especially of high frequencies, pass with astonishing freedom through even slightly rarefied gases. The upper strata of the air are rarefied. To reach a number of miles out into space requires the overcoming of difficulties of a merely mechanical nature.

FM signals and those of broadcast television...travel out to space at the speed of light. Any eavesdropping alien civilization will know all about our TV programs (probably a bad thing), will hear all our FM music (probably a good thing), and know nothing of the politics of AM talk-show hosts (probably a safe thing).

Well, I hate to admit it, but it is possible that there is (one) such a thing as telepathy and (two) that the CETI project's idea that we might communicate with extraterrestrial beings via telepathy is possibly a reasonable idea--if telepathy exists and if ETIs exist. Otherwise we are trying to communicate with someone who doesn't exist with a system which doesn't work.

It win be a device that will permit communication without any time interval between two points in space. The device will not transmit messages, of course; simultaneity is identity. But to our perceptions, that simultaneity will function as a transmission, a sending. So we will be able to use it to talk between worlds, without the long waiting for the message to go and the reply to return that electromagnetic impulses require. It is really a very simple matter. Like a kind of telephone.

What I tell business leaders is you're in the space industry - you just don't know it yet. Every industry will be impacted by space. The internet would not exist without space-based communication.

Here, in low earth orbit, we're going around the earth, so we can actually use an Internet protocol phone because we have the appropriate satellites that can get those bandwidths.

The communications delays between Earth and Mars can be half an hour or more, so the people on the ground can't participate minute by minute in Mars surface activities.

The one thing that really terrifies me is we're going to get a signal from space that clears it all up: 'OK, this is how the universe works, guys.'

Mission Control in Houston receives our e-mails through a satellite and then sends them out to our family and friends. Likewise, any e-mails written to us go through the Mission Control, and then they send them up to us via a satellite.

In any case, the leading edge of our "on purpose" radio signals is 30 light-years away and, if intercepted, may mend the aliens' image of us based on the radio bubble of our television shows. But this will happen only if the aliens can somehow determine which type of signal comes closer to the truth of who we are, and what our cosmic identity deserves to be.

Commercialization of assets off the planet would mutually reinforce the growth of interplanetary communication.

Roger, Tranquility. Be advised there are lots of smiling faces in this room and all over the world. Over.

Perhaps the safest thing to do at the outset, if technology permits, is to send music. This language may be the best we have for explaining what we are like to others in space, with least ambiguity. I would vote for Bach, all of Bach, streamed out into space, over and over again. We would be bragging of course, but it is surely excusable to put the best possible face on at the beginning of such an acquaintance. We can tell the harder truths later.

There is a project that's underway called the interplanetary Internet. It's in operation between Earth and Mars. It's operating on the International Space Station. It's part of the spacecraft that's in orbit around the Sun that's rendezvoused with two planets.

Sending greeting cards to aliens is hardly a new idea. In 2005, Craigslist solicited messages for broadcast to space by a transmitter in Florida, and in 2008, NASA beamed a Beatles song to the North Star (Polaris), on the assumption that any putative Polarians would appreciate the Fab Four's 1960s-genre compositions.

One orbit, with a radius of 42,000 kilometers, has a period of exactly 24 hours. A body in such an orbit, if its plane coincided with that of the Earth's equator, would revolve with the Earth and would thus be stationary above the same spot on the planet. It would remain fixed in the sky of a whole hemisphere ... [to] provide coverage to half the globe, and for a world service three would be required, though more could be readily utilized. (1945) [Predidicting geosynchronous communication satellites]
