April 8 is the date of opposition, when Mars, Earth and the sun are arranged in a nearly-straight line.
If the orbits of Mars and Earth were perfectly circular, April 8 would also be the date of closest approach. However, planetary orbits are elliptical — that is, slightly egg-shaped — so the actual date of closest approach doesn't come until almost a week later.
On April 14, Earth and Mars are at their minimum distance: 92 million km, a 6+ month flight for NASA's speediest rockets. You won't have any trouble finding Mars on this night. The full Moon will be gliding by the Red Planet in the constellation Virgo, providing a can't-miss "landmark" in the midnight sky.
Remarkably, on the same night that Mars is closest to Earth, there will be a total lunar eclipse. The full Moon of April 14-15 will turn as red as the Red Planet itself.
