NASA, after being so disappointed in you for not giving scientists what they need, I can finally applaud your efforts.
Finally NASA is divulging information on their latest efforts to speed up data transmissions in LEO, from Mars, and even beyond. They will be using
lasers so they will still have to obey the speed limit of light but they will increase bandwidth to beyond gigabit speeds. There will still be latency
that will increase based on how far away a said transmitter is to a receiver but the amount of data you can push over the pipe will be increased
significantly. Since they will be streaming the data, this limitation will not matter except when you have to send commands back up the pipe.
For example, if a Mars rover had this tech you would still experience the delay between sending a command and the rover receiving it. Then you have to
wait the same amount of time for the rover to send verification back to you. Essentially, you would not know if your commands worked for several
minutes depending on its relation to Earth. The difference will be in the amount of data you can send at one time. I just hope NASA makes the data
available on the Internet when they start using this tech. I want my high def videos of Mars!
I find this very exciting because we would be able to stream high definition video or any other data for that matter which will increase our potential
for discovery. Thank you NASA for making advancements in this area.
The payload will include telescopes, lasers, mirrors, detectors, a pointing and tracking system, control electronics, and two different types of
modems. One modem is ideal for communicating with deep space missions or tiny, low-power smallsats operating in low-Earth orbit. The other can handle
much higher data rates, particularly from Earth-orbiting spacecraft, including the International Space Station. "With the higher-speed modem type,
future systems could support data rates of tens of gigabits per second," Israel said.
