More info from this 2014 blog post on the astronomical bits about retrograde motion. http://blog.hmns.org/2014/04/mars-viewing-april-texas/ Remember the blog post is from 2014 and is based in Texas.
Yes, Mars does this retrograde dance every 2 years. One of the repetitive astrological cycles which is interesting to see happen.
