NASA on forced pause: A temporary radio silence with Mars has just begun. Find out why Mars missions, including the famous Curiosity and Perseverance, have stopped communicating with Earth.

NASA can no longer contact all its robotsrobots On Mars from November 11th. This is due to a well-known phenomenon, the conjunction of the planet with the Sun, as seen from Earth, occurring approximately every two years (see article below for previous information). During this period, Earth and Mars are aligned on either side of our star (see video below). In fact, coronal mass ejections threaten to degrade radio signals between the two worlds. This is why the US space agency prefers to avoid communicating with its machines on Mars during this entire period.

For once, the robots will be left to their own devices. Although they will remain silent for some time, they will continue to record valuable information. That’s it, they will be sent to Earth only later. This situation is expected to persist till November 25, 2023.

The same thing happens every two years. The Sun slips between Earth and Mars. A delicate moment for the engineers who operate it missions to marsmissions to mars, Therefore, it would be better for them to avoid sending orders to them. The next of these combinations will begin on October 2, 2021.

Perseverance, SimplicitySimplicityCuriosity, insightinsight, Mars Odyssey, Mars Reconnaissance Orbiter (MRO), MAVEN. Just to name NASA. There are many missions going on in and around Mars. The problem is that a solar conjunction is in sight. This happens every two years. Our Earth and the Red Planet will then find themselves on either side of the Sun. And this yardyard The heat and ionizers that make up our star’s crown could, at that point, interfere with the radio signals that teams on Earth want to send to Mars missions.

As a security measure and to avoid compromising the future of its missions, NASA has decided to stop all communication of the command with its machines at least between October 2 and 16. To prepare for this off-peak period, engineers have already sent some simple commands to various machines. Like a list of homework to be done during the holidays.
