Yes , generally . The challenge is that the signal from the spacecraft is very , very low energy . because the transmitter is fairly low power . Space , in general , is a fairly noisy place . electromagnetically , anyway . Sort of like static you hear on a radio . So , the signal being sent has to be able to be detectable at a level above this background noise . This is done with very sensitive receivers . those massive dishes you might have seen pictures of . These huge dishes can capture a lot of radio waves , and then feed them into signal processors special computers that can find the spaceship signal out of all the noise . Sending from Earth , however . we can send very powerful signals as we have all the power we need so that a spacecraft with it ' s small antenna dishes can pick it up . I don ' t think in the case of Voyager we can actually still talk to it . but it may still be able to talk to us .
