NASA back in touch with Voyager 2 after 'interstellar shout'

The Deep Space Network used the highest-power transmitter to send the command (the 100-kw S-band uplink from the Canberra site) and timed it to be sent during the best conditions during the antenna tracking pass in order to maximize possible receipt of the command by the spacecraft.

The probe began returning science and telemetry data at 12:29 am Eastern Time on August 4, "indicating it is operating normally and that it remains on its expected trajectory."
