Copperhead is a c/10 orthogonal spaceship discovered by 'zdr' on March 5, 2016.[1]
Reactions
The ship hauls a block behind it, which makes for interesting reactions involving other ships. Dean Hickerson built a sawtooth that uses copperhead's ability to turn a heavyweight spaceship into a loaf.[2] It can also eat gliders and middleweight spaceships cleanly from behind, and lightweight spaceships from the side of the block. Its front end can cleanly burn through blinkers, creating a c/10 blinker fuse.
Simon Ekström found a tagalong with a large spark on March 20, 2016.[3] Tanner Jacobi noticed that it can be attached to two other identical tagalongs, thus allowing for ships of arbitrary size.[4] Nico Brown built a puffer and a rake using copperheads with tagalongs to make a signal loop.[5]
Synthesis
The first synthesis was proposed by Aidan F. Pierce on the day of discovery. An alternative synthesis utilising fumarole as a predecessor, presented by Tanner Jacobi an hour later, was much more efficient. After optimizations by Mark Niemiec and Chris Cain the total synthesis cost made 22 gliders. A copperhead gun was then completed by Alexey Nigin on March 6, 2016.[6] A faster gun was constructed one day later.[7]
The first copperhead to emerge from the ash of a soup appeared on April 4, 2016 in a D2_+2 haul submitted to Catagolue by Apple Bottom.[8]

In other rules
In the cellular automaton DryLife, an extremely similar spaceship (dubbed the goldenhead) also travels at c/10 orthogonal. It differs from the normal copperhead by 2 cells in one phase. A normal copperhead at this phase will turn into a goldenhead in DryLife, and conversely this phase will return to a copperhead in normal Life.
