In May this year, China National Space Agency successfully landed its first spacecraft on Mars and from now on Zurong Crossing the red planet, keeping the American company curiousity. This means that it has collected a lot of useful new data about the climate and the surface and interior of the planet that must be sent back to Earth for analysis. This is where unmanned space mission orbiters come in, which, like rovers, are equipped with radio transmitters.

Thanks to this, they receive data from roving vehicles and then transmit it to Earth – and large antennas await them in places such as belonging to the This is amazing space tracking network ask (European space tracking). It often operates such that it intercepts orbiters belonging to one agency and sends data obtained by its rover and other space devices, ignoring those belonging to foreign agencies (although cooperation between ESA and NASA is standard).

However, that is only changing, because soon the European and Chinese space agencies will band together and try to send data from the Jurong spacecraft to the orbiter. Mars Express Using a new technique called listening. The task, however, will not be simple, because in theory the transmitters of the devices are not compatible with each other – this means that Zhurong cannot hear the signals sent by the Express Orbiter, which is waiting for roving vehicles to begin transmitting data.

The ESA and NSA will test a new method, which has only been previously tested on the ground. During five tests, the Zhurong rover will send a blind signal into space, and the Mars Express will listen for it: – If the Mars Express detects a magic signal, the transmitter will stop there and start recording data. At the end of the communication window, the probe will face Earth and transmit this data in the same way it does on other Mars missions. When the data reaches the European Space Operations Center, it will be sent to the Zhurong team for processing and analysis, reads the official entry on the ESA website.

As mentioned earlier, this is an unusual attempt, but if successful, it could be a backup plan for both agencies in the event of disaster, even for theoretically incompatible systems. The tests were scheduled for November 7, 16, 18, 20 and 22, so you should expect information about the possible success of the mission on these dates.
