  2. The perfect alignment of events made this ESA first possible: 🛰️two spacecraft close in the sky 👂both able to receive signals at different wavelengths 📡a deep space station able to send both ‘telecommand’ signals simultaneously 🎞️

  3. The test, the first of its kind, saw the deep dish use both of its transmitters at the same time to control Mars Express and ExoMars TGO. Speaking to in the 'S-band' and in the 'X-band', ensured the messages did not interfere

  4. Called ‘Multiple Spacecraft Per Aperture’ , the technique is used routinely by ESA’s and 's But MSPA only works one way. While the ground station can receive data from multiple spacecraft, it can only ‘speak’ to one at a time

  5. When several spacecraft are located in one part of the sky (all in orbit around Mars for example), it's possible for an antenna to ‘see’ all of these spacecraft at once. As ESA have four receivers, they can receive data from up to four spacecraft simultaneously

  6. The vast majority of conversations between Earth and space involve one antenna on the ground, one in orbit or out in the Solar System, and signals at a particular frequency going between the two

  7. Late on Thursday 30 January, the 35-metre dish in Western Australia ‘spoke’ to and the ExoMars Trace Gas Orbiter (TGO). Talking with two voices at two different frequencies ensured the signals sent didn't interfere with each other
