Weekender is a 2c/7 orthogonal spaceship that was found by David Eppstein on January 12, 2000.[1] On April 27, 2000, Stephen Silver found a tagalong for a pair of weekenders (shown below). At present, n weekenders pulling n-1 tagalongs constitute the only known spaceships with speed 2c/7, besides self-sustaining loops of weekender conduits. These were the only known period-7 spaceships until the discovery of lobster in 2011 and the loafer in 2013.

Despite the relative simplicity of its components, a glider synthesis for the weekender had been elusive since its discovery. A weekender synthesis was completed on January 25, 2015, 15 years after its discovery (and coincidentally, on a weekend).[2]
