NASA hears signal from Voyager 2 spacecraft after mistakenly cutting contact

• runjake 3y ago
  Unless I'm mathing wrong, it takes about 22.5 hours for the signal to travel to/from Voyager 2 to earth, one way. 15 billion miles / 186,282 miles per second = 80,414 seconds

  Does this mean low gain is sending a heartbeat but high gain is still misdirected until reset in October? From the diagram on this page [1], it seems like dish positioning is critical to both antennas.

  > If the command doesn't work - and controllers doubt it will - they'll have to wait until October for an automatic spacecraft reset. The antenna is only 2% off-kilter. That's pretty smart to have such an automatic restart configured. I wonder what the details are - do they pre-program an antenna attitude for a specific moment in time, then do the reset if it's not overridden before the target date?
