Since when could Satellites can see in the past?
If you put a telescope on the moon, you could see 1.3 seconds into the past on Earth because that's how long it takes light to get to the moon, approximately. However you'd have a heck of a time identifying the bank robbers or the car with currently available telescopes. It would probably need to be huge to do that, and 1.3 seconds isn't far enough in the past to help much.

If you can see the past , you can solve the problems that occurred or find the cause.
Nonsense, because the "information" that's transmitted is also nonsense like a random sequence of 1s and 0s, so how does that help? It doesn't help with faster communication but entanglement technology is useful for cryptography, the light speed or less variety.

Yes, quantum entanglement (QE) could allow for instantaneous information relay from any distance. This is why NASA is pushing hard to develop QE comms gear for use on their interplanetary and deep-space probes.
Just a small fraction of a second for low Earth orbiting satellites.

Quantum entanglement DOESN'T send any information faster than light. This is one of those things everyone seems to think and they keep saying in popsci that's just plain wrong. The changes caused by entanglement contains no usable information on its own, if you want to send information with it like they do in quantum teleportation experiments you need a classical communication channel along with the entangled pair, 2 classical bits must be sent for each quantum bit (qubit). Since the classical channel is limited to light speed, the whole process is limited to light speed.

So on the quantum entanglement if you can transfer data somewhat like morse code or even 1's and 0's can you do interface it with a satellite x AU away?
The communication between earth to the satellite would be Instantaneous
Here's a light example
Someone robs a bank and gets away. No video feed on the car or person whom did it. They contact the satellite and the satellite positions itself to that bank, bam starts recording so it's essentially seeing the past , depending on how far out the satellite is.
Sees a car pull up a black charger with 3 personnel get out, has the car and possibly anything else it saw maybe even where they came from.
Very cool thoughtful technology could be used on a wide array of things such as terrorists attacks, assanation, natural disasters, to find out what happened leading up to this.
If you can see the past , you can solve the problems that occurred or find the cause.
Thanks for doing the research, and you found out all those sources talk about encryption as the application for quantum entanglement, right? It's not faster than light but it's useful and is the focus of considerable research.

NASA is certainly researching QE:
NASA | Quantum Communications at Glenn Research Center
NASA | NanoRacks-GOMX-2 Small Photon Entangling Quantum System
And this one because it has a fun cartoon in it. lol
NASA | Researchers Advance Quantum Teleportation
However, it looks like I stand corrected on the idea of QE instant comms (according to our current understanding of QE):
Quora | QE Instant Comms?

Yet he doesn't seem to look all that hard for alternate explanations. It may have convinced him but it's not that convincing to me. By the way would you happen to have a link to the ATS thread on that?
Believing in faster than light communication via entangled particles was held by most scientists to be roughly as close to lunacy as believing in Bigfoot; it was to invite the scrutiny and derision of your peers. I wasn’t comfortable with that.
It will take our fastest spacecraft about 15,000 years to get to that position. So let's say on January 1 15,000 years from now, you send a signal to this hypothetical probe. It will take a year for your request to reach the probe, and a year to send you something back in response to your request. If you request it to send a recording of Earth it made on January 1 15,000 years from now, on January 1 15,002 years from now you'll see a recording of what the Earth looked like on January 1, 14,999 years from now.

So if we sent this/A satellite 1 light year, we then would see further into the past/future?
Then when the information coming back to us then we could then see everything it allows us to then the further it goes the more we see or communicate with?
Just trying to get my head around it.

That fanciful tale is far from credible. What exactly led you to conclude he was "not some idle storyteller"?
