Yesterday’s question was: “Name the US Space Shuttles. How many missions into space did each Space Shuttle fly? Which Shuttle is now at which museum?”

The answer is:

• Columbia (OV-102), first flew on April 12, 1981. Completed 27 missions, and disintegrated during re-entry on its 28th mission, on February 1, 2003.
• Challenger (OV-099), first flew April 4, 1983. Completed nine missions, and exploded 73 seconds after launch on its 10th mission, on January 28, 1986.
• Discovery (OV-103), first flew on August 30, 1984. Completed 39 missions, landing for the final time on March 9, 2011. Discovery is on display at the Steven F. Udvar-Hazy Center of the Smithsonian National Air and Space Museum at Dulles International Airport, Fairfax County, Virginia.
• Atlantis (OV-104), first flew on October 3, 1985. Completed 33 missions, landing for the final time on July 21, 2011. Atlantis is on display at the Kennedy Space Center Visitor Complex, Merritt Island, Florida.
• Endeavour (OV-105), first flew May 7, 1992. Completed 25 missions, landing for the final time on June 1, 2011. Endeavour is on display at the California Science Center, Los Angeles, California.
• Enterprise (OV-101) was built as a test vehicle, without engines or a functional heat shield, and thus, not capable of spaceflight. It flew in the atmosphere after, being released from its Boeing 747 Shuttle Carrier Aircraft, five times between August 12 and October 26, 1977. Enterprise is on display at the Intrepid Sea, Air & Space Museum, New York, New York.
• Pathfinder (unofficially known as OV-098) is a Space Shuttle test simulator made of steel and wood. Constructed in 1977 as an unnamed facilities test article, it was used to check roadway clearances, crane capabilities, and so on. After the Space Shuttle program no longer needed it, it was sold to the America-Japan Society, which displayed it in the Great Space Shuttle Exhibition in Tokyo from 1983 to 1984. Then it returned to the US, and is on display at the US Space & Rocket Center in Huntsville, Alabama.

Today’s question is: Cent, nickel, dime, quarter, half dollar, and dollar. The US has six circulating coin denominations. List them in order of the longevity of the current design. Bonus points if you can name whose face is on each obverse, and what design is on the corresponding reverses.

Ian’s Tough Trivia is a daily feature of this blog. Each day, I post a tough question, as well as the answer to the previous day’s question. At some point, I’ll offer a prize for whoever has the most correct answers, and another for whoever participates most often (I’ll take into account people coming in after the start: regular participation starting later is just as good as regular participation starting earlier). There may also be a prize for the funniest or most amusing wrong answer. Simply comment on this post with your answer. I’ll approve the comments after the next question is posted. Sure, you can probably find the answers by searching the web, but what’s the fun in that?
