It also shares the name with the Endeavour space shuttle, an orbital space vehicle used by NASA as an active participant in the construction of the International Space Station. Both vessels use the British English spelling of the word, rather than the American English form, in honor of the British HMS Endeavour, the ship of Captain James Cook on his first voyage of discovery (1768–1771).^[3]
