How does ESA adapt to the current confinement procedures ?

How will we continue to support space operations whatever happens on the ground ? What if there is such an outbreak with a manned mission already in flight to Mars ? It isn’t easy to reach Mars but imagine it without ground support ?

Life on Mars

While looking at pictures of Mars, I found this one, dating back from 2016, and found it very precise and encompassing a lot of key information on Mars. As usual National Geographic both clear and precise.
