Astronomical research: the conjunction of Mars with the sun tomorrow and the interruption of spacecraft communications


The National Institute for Astronomical Research revealed that with tomorrow, Friday, Mars will pass close to the sun, as its orbit around the sun will carry it to the far side of the solar system and farthest from Earth.

When Mars approaches the Sun, it will appear at an angular distance of only 39 arc minutes from the Sun, making it completely invisible for several weeks, as it will disappear in the glare of the Sun.

This coincides with the presence of Mars at about the same time at its farthest distance from Earth, as it will recede to a distance of 2.63 astronomical units (an astronomical unit is the average distance between the Earth and the Sun and equals approximately 150 million km). On two opposite sides of the solar system.

The sun will be between Earth and Mars, and Mars will appear smaller and dimmer than Earth because of its large distance, and its angular diameter will be reduced to 3.6 arc seconds.

All communications to and from spacecraft exploring Mars will be suspended during the period of Mars conjunction with the Sun, which may cause distortion in signals from ground control units to vehicles on Mars and back, or the loss of any important data due to the impact of charged particles emanating from the Sun.
