Attended a midnight showing of Prometheus. The takeaway? Occasions arise when being curious is bad for your life expectancy. — PolitiTweet.org

Space Shuttle Endeavour, soon to rest at the Cal Sci Center, was named for Captain Cook's ship - hence the British spelling. — PolitiTweet.org

Captain Cook saw the June 3, 1769 Venus Transit from South Pacific, also mapping islands there for later British colonization — PolitiTweet.org
