A crippled antique corvette whose repair is the castaways' only practical route from the sunward waste back toward Mars.
The Archimedes is a fifty-meter corvette stranded with Darrow and the surviving Martian soldiers on Marcher-1632. Its damaged reactor and hull have reduced its passengers to hand-welding patches in hostile sunlight while they wait for helium to restore power.
The ship represents an escape route rather than safety. Cassius au Bellona took its only functional relic craft toward Starhold to obtain the helium, leaving the castaways dependent on his return and Cadus Harnassus's work on the reactor.
An antique fifty-meter corvette, crippled and scarred, lies tethered in the shadow of a waste escarpment. Welders in battered space suits crawl over its hull, sealing panels by hand.
The Archimedes is the marooned survivors' transport, workshop, and immediate hope of reaching Mars.
