Are there any technical details available? It would be super interesting to see all the stuff that is re-developed from old specs, and to see how all the calculations and commands fit together to reach thw mission goals, or even what the received data and telemetry looks like.<p>Or is this kept confidential to try to prevent outsiders from going at it like in that xkcd posted in the comments here? Or is the only &quot;protection&quot; based on the requirement to have access to those huge observatories?

If they do manage to fire the engines, it has to pass through the lunar shadow on the way back to Earth and as it&#x27;s running off solar panels this means a total shutdown, which it&#x27;s never done before (alas, the uptime!). Let&#x27;s hope it comes back up!

Whoa I did not know anything about this story until now &gt;&lt;<p>On a related note, I also just noticed that the &quot;Arecibo Radio Observatory&quot; was in Goldeneye!

&gt; We have successfully commanded both of ISEE-3&#x27;s data multiplexers into engineering telemetry mode. The current bitrate is 512 bits&#x2F;sec.<p>BITS not even BYTES, let alone kilobytes.

Is this the satellite NASA had given up because there was no communications equipment left?

Twitch spacecraft anyone?

The fact that this machine is still in operation is awesome. What a piece of engineering.

Brilliantly impressive. Especially considering they&#x27;re operating out of an old McDonalds on the NASA Ames campus.
