Mars Communication Cut Off
The National Aeronautics and Space Administration (NASA) is cutting off radio commands to its missions on Mars as its orbit moves to the opposite side of the Sun. The two-week period referred to as the solar conjunction will run from October 2nd through 16th and occurs every two years. The Sun’s intense radiation prevents radio signals from safely traveling between Earth and Mars during the conjunction, meaning researchers and technicians on Earth need to give long-term assignments for the landers and rovers on Mars to keep them occupied until commands can be transmitted again.
