Pictures from Mars to Earth are clear. Pictures from Britain to Britain far less so.

The world has just seen astonishingly-detailed clear pictures from the surface of Mars, courtesy of an American rover called Perseverance [affectionately abbreviated to Percy].

However when BBC Newsnight proudly showed them [on February 24 2021], as a marvel of human achievement, it also linked up with a scientist in Britain.

Except the picture of him was scrambled and then disappeared.

Perhaps it was an extra-terrestrial message — that the BBC should pay more attention to getting things right, pictorially and perhaps in other respects, right here on Earth?
