(Ausgliederung aus dem Rosetta-Thread)
Während Rosetta erwacht ist, kann die Sonde ISEE-3 (International Sun Earth Explorer-3) - ICE (International Cometary Explorer) leider nicht mehr mit uns sprechen, nein, wir können nicht mit ihr sprechen. Es fehlt das irdische Equipment hierzu.
Communication involves speaking, listening and understanding what we hear. One of the main technical challenges the ISEE-3/ICE project has faced is determining whether we can speak, listen, and understand the spacecraft and whether the spacecraft can do the same for us. Several months of digging through old technical documents has led a group of NASA engineers to believe they will indeed be able to understand the stream of data coming from the spacecraft. NASA's Deep Space Network (DSN) can listen to the spacecraft, a test in 2008 proved that it was possible to pick up the transmitter carrier signal, but can we speak to the spacecraft? Can we tell the spacecraft to turn back on its thrusters and science instruments after decades of silence and perform the intricate ballet needed to send it back to where it can again monitor the Sun? The answer to that question appears to be no.
