Engineers from NASA have reported that in June 2015 due to the so-called phenomenon of the "Union of the Sun to Mars' communication with working on the orbit of Mars and on its surface devices will be kept to a minimum $ CUT $.

Location of the sun between Earth and Mars is called the "Union of the Sun to Mars." This happens roughly every 26 months, as a result of the difference between the orbits of Earth and Mars.

 The Sun in this period overlaps Mars, and because our star is a huge source of electromagnetic noise, scientists are concerned that solar radiation can disrupt the command codes and damage onboard computers research units.
Research groups working with three orbital Martian machines - «MAVEN», «Mars Odyssey», «Mars Reconnaissance Orbiter» and the two Mars rovers - «Curiosity» and «Opportunity» will refrain from sending commands to the vehicles in the period from 7 June to 21 June . It is also planned that the resulting information in this period will be sent to Earth later, after the installation of a stable connection, to avoid data loss.
