In the spirit of what this community's name suggests it's about, how hard would it be for someone to hack into the spacecraft by sending it a signal to turn on its thruster too soon given the technology is 40 years old?
Has anything like this been tried before with other spacecrafts?
- darkr 9y agoI guess along with knowing the signal protocol you would need to know the exact location. Security via obscurity?
- gregorkas 9y agoI imagine that with cracking the protocol with 39 hours return time... it would be a challenge.
- FireBeyond 9y agoAt a mammoth 16bps... And then the 20kW+ transmitter you'd need...
- AnssiH 9y agoI think Voyager data rate is 160bps (when I last saw it at https://eyes.nasa.gov/dsn/dsn.html https://eyes.nasa.gov/dsn/dsn.html ).

- rurban 9y agoNope, Arecibo is not used for this. The Chinese FAST would be perfect for this also.
- ewams 9y agoYou are correct this wasn't the article I was looking for, didn't read it to verify. I can't find it now but 1-2 years ago some people used that dish to reactivate a "lost" satellite that had not been used for several years.

Perhaps listening to the traffic could help deciphering the encryption (if any). What it wouldn't be easy at all is to have antennae large enough and in various parts of the world: amateurs still don't have the capacity to do that. > Has anything like this been tried before with other spacecrafts? The only thing I can remember is reviving an old satellite with linux and SDR (https://www.ettus.com/blog/2014/07/contacting-a-36-year-old-space-craft-why-not https://www.ettus.com/blog/2014/07/contacting-a-36-year-old-...) but that was with some cooperation on part of NASAs.
- b3lvedere 9y ago"how hard would it be for someone to hack into the spacecraft by sending it a signal" You'd need to totally own the DSN. According to the Wiki: Because of the enormous distances and the resultant weak signals from the spacecraft, the large antennas and the very sensitive receivers of the DSN are required to provide the necessary communications capabilities. The DSN is the world's largest and most sensitive spacecraft communications network. It consists of three deep space communications complexes located approximately 120 degrees of longitude apart around the world: at Goldstone, California; near Madrid, Spain; and near Canberra, Australia. This placement permits continuous communication with a spacecraft.
- mturmon 9y agoThe NASA Terra Earth orbiter was successfully attacked in 2007/8 — http://resources.infosecinstitute.com/hacking-satellite-look-up-to-the-sky/ http://resources.infosecinstitute.com/hacking-satellite-look... “The best known of alleged takeovers of satellite control occurred in 2007 and 2008. In particular, a serious attack was observed in 2008 when hackers obtained the control of the NASA Terra EOS earth observation system satellite for 2 minutes in June and for another 9 minutes in October. Fortunately the attackers didn’t damage the satellite during the time they gained control of it.”
