In simple words
A transit is where a planet is in the sky now, compared with your birth chart. Here, today's Mars makes a square (90°) to the spot where your Moon was when you were born.
It is a time of pressure that pushes you to grow, and it lasts about a week. Your Today page tells you when it is happening for you.

About the square
A square sets two planets ninety degrees apart. Their needs pull against each other and ask for action. Squares feel like tension or recurring challenge, and they are also where much of our drive and achievement comes from. Working with a square, rather than against it, often builds a remarkable strength.
