600 Mbps....On The Moon
by Karl Bode 06:28PM Tuesday May 27 2014
Last year NASA announced that the agency would be conducting a Lunar Laser Communication Demonstration (LLCD) they believe will someday be capable of delivering speeds up to 600 Mbps. The test was successfully conducted last October, and involved communicating with the LADEE robotic probe orbiting the moon using telescopes that are just under one meter in diameter. NASA believes that these telescopes can eventually be re-engineered to receive 2.5 gigabits per second if made larger (up to three meters).

According to a NASA statement, the space agency managed to transmit data 384,633 kilometers (239,000 miles) from a ground station in New Mexico to the LADEE robotic spacecraft. NASA only recently issued more detail on the test, noting the technology performed better than expected in various conditions:
quote:
NASA says that the LLCD mission performed better than expected during its 30-day trial. The laser was able to communicate with the Earth stations in broad daylight and even when the Moon had less than four degrees of separation from the Sun. It also worked without error when the Moon was low on the horizon, forcing the laser to pass through a much thicker layer of atmosphere, with atmospheric turbulence having little effect.
With a little more work, scientists believe the system could be used for high-speed broadband delivery to Mars. More detail on the efforts are expected to be unveiled on June 9 at the CLEO laser technology conference in California.

What kind of latency?

What kind of ping times do you think we'd get?

Re: What kind of latency?

The study doesn't say, but considering light takes about 1 second to get to the moon and back, probably not bad for little things like e-mail, web browsing, streaming video, not so much for gaming. So no Zero-G Call of Duty tournaments

Re: What kind of latency?

Just have to settle for LAN games on the moon, or a local moon ISP.

For satalite internet ping times of 1 second round trip are good as you get (500ms each way) So for a lazer to get to moon at back would take acording to »www.bbc.co.uk/learningzone/clips···221.html

"How long does it take reflected light to travel from the Moon to the Earth?
Duration: 00:39
The presenter calculates the time it takes light, which is reflected off the Moon, to reach our eyes. As the Moon is 400,000km from the Earth and the speed of light is 300,000km/s the time taken is about 1.3 seconds.
Subject: Science Topic: Phys: Waves - Sound and Light
Keywords: light source, reflected light, light travel, moon, speed of light"

1.3 seconds each way round trip ping would be by necessity 2.6 seconds.

That would be the absolute fastest possible other factors would increase the actual ping time.

It varies a lot but in July 2018, it will be a blazing 384,946ms. At the opposite end of the scale it can be at least as much as 2,677,419ms.

Edit: This is for Mars, not the moon. I had Mars in my head because they want to use it for communications with Mars. Communicating with the moon doesn't seem as interesting.

latency is about 2.6 seconds or 2,600ms

dial up is about 100ms to 500ms
Satellite Internet is about 500ms
Cable Internet 75ms DOCSIS 3 ( 73ms for DOCSIS2)(from LA to NYC)
DSL about 90MS to 120ms (from LA to NYC)
Fiber about 70ms (from LA to NYC)

So what you're saying is...

One can get faster internet access on the moon than I can in my house on earth? This is not the 21st century I was told.

Not really, you CAN get gigabit internet at your home. Whether the ISP provides that is another matter.

Fixed that for you. You can get fiber to your house even in areas where it is currently not offered as an inexpensive residential service. You just have to be willing to pay to have fiber run and equipment installed...any ISP will do this provided they get a return on their investment.

I call bull on that. I live 2500 feet from a Verizon CO they refuse to lay fiber. And I offered to pay for it. Some ISP just want to be jerks.

so call someone else like Zayo who build commercial fiber networks rather than residential ones like VZ

If you really are offering to pay the construction costs and are purchasing services worth their investment, they won't turn you down - frankly, I don't think VZ would either but I wouldn't do it for residential rates if I were them either.

600 Mbps, but what are the caps?

600 Mbps means that you hit your cap faster.

600 Mbps will suck when there's lots of users.

They better upgrade that. I mean you can use local internet for the moon, but if there's lots of people on some moon base, everybody has to share a high latency 600 mbps connection to contact loved ones on Earth.

And before you get local internet of some sort up and running you'd have to depend on that connection..

Yes

That capacity is for 1 device on moon and a matching transceiver on earth. Add capacity by building more device pairs.

with a large local cache that would not be a issue

In related news

In a related article: Charter got the bid to provide the service. So 600 down and 4 up and the rumor is that in a year they are going to upgrade, for free, to 2.5 gig down and 5 meg up!!!! Whooo hoooooo!!!

Someone's gonna say it, so I might as well

600Mbps from the Moon, but TWC couldn't deliver more than 50Mbit in most areas for over 3 years...over coax! And Frontier can't deliver more than 3Mbit to most of its footprint. Stop me if you've heard this one before.

AT&T proposes using a long copper wire pair and VDSL2 from the orbiting LADEE robotic probe down to the lunar surface. Bonded VDSL2 within 5 years.

Message from the Elite to "serfs"........


Elite to the serfs------>
LET THEM EAT CAKE.

Considering that the ovehwhelming majority of US citizens can barely get better than 3/1 service, and for a outrageous price, shouldn't our gov't be addressing technological problems that affect our citizens on earth first?

Don't even start with the "outrageous price" thing, this whole lunar experiment cost a great deal more then you could possibly spend on broadband in your lifetime.

That is the whole point of NASA, To improve life on Earth. NASA is worth more to the US than a whole fleet of new aircraft carriers. Sadly NASA gets cuts and the Navy gets carriers. Today we still benefit from breakthroughs made during Apollo and the Shuttle.

The biggest point of things like this is that its allowing the development and proving of technology to allow laser over extreme range through an atmosphere. After all current laser is usually just to another building in the same office park and that gets screwed by rain.

Couldn't we try to offer broadband to every town in the USA

BEFORE we worry about furnishing Internet to the Moon?

Last time I looked, no one lives on the Moon.

Silly advancements in science. People complain when the US isn't leading the charge in new technologies and then they complain when it is on the forefront.

600 Mbps to the moon yet AT&T can only deliver 6 Mbps via fiber

I read stuff like this and it pisses me off even more that AT&T can only deliver 6 Mbps via fiber to the curb.
