Spider is an orthogonal c/5 spaceship that was discovered by David Bell in April 1997. It is the smallest known c/5 orthogonal spaceship. Its side sparks have proven to be very useful in constructing puffers and rakes.
On March 7, 2019, Martin Grant found a 601-glider synthesis of spider, making it the first c/5 orthogonal spaceship to be synthesized.[1]
