By BERNIE REIM Share This photo provided by NASA shows the first color image sent by the Perseverance Mars rover after its landing on Thursday, Feb. 18, 2021. NASA/JPL-Caltech via AP The month of March is named after Martius, the father of Romulus and Remus who founded Rome, the world’s first superpower, according to mythology. March used to be the first month of the year on the early Roman calendar and is also named for the planet Mars, who is the god of war. That is fitting for this particular March, since Mars will be the only evening planet visible all month long.
