Quoting: Anonymous Coward 11384691 Tell me how ANY difference could exist! Checksums work the SAME WAY, no matter the distance. LOL@ Comparing DIVX codec to error handling on 35 million mile data transmission. Quoting: Anonymous Coward 11384691 Tell me how ANY difference could exist! Checksums work the SAME WAY, no matter the distance. Data transmission layer with ~3-21 minutes latency vs milliseconds. Here is a picture that NASA "downloaded" from mars in 1997, during the Mars Pathfinder mission: [link to upload.wikimedia.org] No "latency" prevented then from "downloading" it. NOTHING can prevent the download of a digital video file from Mars. I don't think you understand how the data is being transmitted. Checksums are used to identify bad data. How do you cope with bad data? You re-send the bad frame of data. Now say you have a burst of data from Mars and end up with bad checksums... You have to transmit the offending frames IDs back to mars and have them resent, while this takes place in milliseconds in 'net-based protocols, it takes much, much longer when talking interplanetary transmissions. So, now say you get back the 'bad' frames an they have errors.... DIVX and interplanetary data transmission are very different things. |

Your P2P client would blacklist the ONE host that is sending data after 3 corrupted chunks. 32kbps sure, when mars is closest to earth (which it is NOT currently) for "couple" hours a day ONLY. And you still have that pesky error rate to deal with. and still not enough for "LIVE HD VIDEO" Never said it was not possible to send video just not "LIVE HD VIDEO". They probally can and will send short video clips over next couple years, even if greyscale and 1 frame/sec. And as many posters said the 1-2 months is just too long to be worth it, besides it not like martian are try to talk to rover, and we are try to read their lips, cause someone forget to but microphone on rover (it probally has one...hmmm 32kbps is enough for most basic LIVE AUDIO STREAM, atleast 16 hours per day when mars is closer to earth) |

Quoting: Anonymous Coward 21484878 And from that kind of distance, even with the best error correction algorithms it's very hard for NASA to receive a very large HD file ! ftp protocol comes to mind.. allows for re-connection and download of files in multiple pieces.. also P2P has come a long way in the past decade and massive files can be downloaded in variable fragments with good success. You are confusing data transmission, network and transport layers. Again, p2p, FTP and others work based off of a whole different data link and transport layer. |

Yes they have it in outback australia knows that a standard satellite connection can be 100 times faster than your standard connection. They could relay it between satellites. Any shill that thinks it can't be done needs to look at things differently.

The only way it has to charge it's batteries is through efficient solar cells and not an electrical outlet socket. There are many instruments on the rover that use bare minimum power to keep everything functioning. Quoting: YibbiY 253796 Actually Curiosity doesn't run on solar cells but gets its power from a radioisotope thermoelectric generator, basically a bunch of plutonium that generates heat that is converted into electricity. Your main point that power is extremely limited onboard the rover is still valid, however. |

It can then be transmitted at a non-real time rate based on the telemetry bandwidth. after reception it again can be played at the real time rate. Very simple. Plenty of error correction and image enhancements can be added to produce great videos. Ominous regressions One Truth... many realities |

Besides conducting its own scientific observations, it has served as a communication relay for NASA's Spirit and Opportunity Mars rovers and the Phoenix lander on the Martian surface. NASA plans to use Odyssey and the Mars Reconnaissance Orbiter as communication relays for Curiosity during that rover's two-year prime mission on Mars." more info: [link to mars.jpl.nasa.gov] Counting Mars Express, there are three, the other two being Odyssey and MRO - MRO being the one that took the awesome photos of Curiosity on the parachute. |
