This image was taken by ESA astronaut Alexander Gerst of the International Space Station on June 30, 2018, when the Moon and Mars were closest during his six-month mission to Horizons.
For purposes of illustration, Mars has been highlighted and enlarged twenty times: The "Red Planet" has a radius of 3389 km, but at that time it was about 67 million km from Earth, while the Moon had a radius of 1
The distance between Mars and Earth varies, as both planets orbit the Sun and are closest in those weeks. They appear brighter than Jupiter in the night sky. The night of July 27 offers another periodic spectacle during the lunar eclipse, when the earth casts its shadow over the moon, making our satellite appear red.
With careful planning and luck, it should be possible to see the red planet and the reddish moon with the International Space Station, which always flies from west to east. On the European mainland, the moon will be overshadowed and the total solar eclipse will last after 23:00.
The International Space Station, Moon and Mars are the targets of the ESA strategy for human and robotic exploration Demonstrating technology, developing the Orion service module and elements for a gateway around the moon and sending robotic probes to Mars such as the ExoMars rover, which drills 2 meters into the surface in search of life.
We'd love all the pictures that show the Moon, Mars and the International Space Station in one go – even better if you manage to get all three during the lunar eclipse.

Alexander took this picture with a 210mm lens when he was not working on the dozens of European experiments on the International Space Station. At a speed of 28,800 km / h, it only takes 90 minutes to orbit the earth, ie the astronauts on board fly through the night every 45 minutes: paired with always clear skies, there are more possibilities for an astronaut, a perfect one To take a picture.
