BahrainLad,
The British one, someone at NASA playing a blinder...
I thought it might have been possible they acquired later, but not so.
"On 21 December 1872 the 2306 ton steam assisted corvette HMS Challenger sailed from Portsmouth on a 3-year voyage of marine exploration which laid the foundations of almost every branch of oceanography as we know it today."
"After her three years of glory, her fate was even more ignominious. Commissioned as a Coast Guard and Drill ship of Naval Reserves at Harwich in July 1876, she was finally paid off at Chatham in 1878. She remained in reserve until 1883, when she was converted into a receiving hulk in the River Medway, where she stayed until she was finally broken up for her copper bottom in 1921."
