"The video signal took 101 seconds to reach Earth, sent at the system’s maximum bit rate of 267 megabits per second (Mbps)."
Based on some quick search, this is comparable to US median broadband download speed.
- xnx 3y agoI think this also means that the the capacity of the empty space in 3.4GB. Someone has previously pointed out the interesting networking/caching(/storage?) implications for such long transmission time.
- EvanAnderson 3y agoIndeed, you could use that empty space as delay line memory. That's some wicked latency, though.
- mk_stjames 3y agoThis idea is covered during the first part of one of my favorite Tom7 videos. If this comment is the first you are hearing of Tom7... strap in and enjoy: https://www.youtube.com/watch?v=JcJSW7Rprio https://www.youtube.com/watch?v=JcJSW7Rprio

- ben7799 3y agoKind of amazing the article doesn't contain the word latency a single time. It's good they're improving throughput/bandwidth but it doesn't help the big problem which is the latency.
- pxeger1 3y agoI mean the latency problem is definitely not solvable, so why would they be trying to work on it?
- basementcat 3y agoThey actually improved the data transfer latency considerably. An earlier version of the DSOC ground receiver was designed to dump data to a hard drive that would then be trucked over to Pasadena. Some joked that more bits might be lost on the I-210 freeway than between the asteroid belt and Earth.
- proaralyst 3y agoThere's a hard physical limit (speed of light) on latency that we can't do anything about. Higher bandwidth deep space communication gives us the ability to recover more science data from robotic missions, so it's worth working on.
