For example, during long phases of motion or when the location of Mars, Earth and the probe in orbit introduces a delay in the transmission and reception of data". In March last year, the rover found on Mars traces of fixed nitrogen in the form of nitrates. As they note, this may indicate the presence of a primitive form of the nitrogen cycle in the ecosystem of the ancient Mars.
