Mars Close Approach happens about every 26 months. It is closely related to Mars Opposition and Mars Retrograde. Since Mars and Earth are at their closest, it's generally the best time to go to Mars. Many Mars missions have taken advantage of the close distance to visit the red planet.
At its most basic, switchel is water, cider vinegar, ginger and a sweetener (molasses, honey, sorghum, etc.). Rum, whiskey, brandy or hard cider can be added to give it a bit more oomph. Iâve seen some recipes, particularly in the south, that add cayenne pepper to the mix as a cold cure.
Although we arenât sure where switchel came from, we do know that colonial farmers believed that drinking hot drinks while working in the Sun was good for you, helping you keep a balanced body temperature in relation to the heat outside. The problem was that no one actually wanted to drink a hot beverage on a hot day.
