The planets Mars and Saturn are both just recently past the time of their respective opposition to the Earth; Mars on May 22nd, and Saturn June 3rd. When the two dates are close then both planets will at some point be at the same heliocentric longitude or at heliocentric conjunction. That will be on Monday June 13th.
While they may share nearly identical heliocentric longitude coordinates they do not have the same right ascension with Saturn about 1 hour of R.A. east from Mars. Both Mars and Saturn are very visible over the southern horizon a couple of hours after sunset. The color of Mars contrasts nicely with the reddish star Antares in the Scorpius the Scorpion.
