Engineers at NASA Laboratory for Reactive Movement in Pasadena,
California, began sending a new set of commands to Opportunity rover
in an attempt to force the 15-year-old Martian
explorer to connect with Earth. New commands to be sent to
over the next few weeks, will deal with low-probable events that they could
have arisen on board an Opportunity that prevents its transmission.
The last communication of the Rover with the Earth was received on June 10, 2018 as a dust on the planet
