Hi currently the furthest man-made objects from Earth Other Voyager space probes launched in 1977, Voyager 2 is currently 17 billion kilometres from Earth. That's like going to Pluto and back and then back to Pluto or Gannett roughly and we can still contact it. How let's find out. So what does it take to track Voyager 2? A big antenna? So in the case of this 70 meter deep space station 43, low noise amplification is important.

so and we certainly don't want to introduce any more noise than serve the skies giving us. So we cool it and all our LNA s are cryogenically cooled about. or a tropical four and a half Kelvin Actually so we only moved in last week. This is this is the new Operations Center for full of the Sun where we start a November where Canberra will control Goldstone and Madrid antenna during daylight hours and that'll rotate.

So they'll control hours during the nighttime. So what we do is we'll send a command sequence and then we listen. Round-trip flight time we we get a happy beep or a sad beep. This is our performance displays so we know exactly where it's pointed.

It gives us an azimuth and elevation 219 and 53. You know everything is milli degrees here. This is our spare 402 kilowatt Klystron. You.
