Washington, April 23 (IANS): If you want to grab a copy of a NASA astronaut's signed picture, join this trivia game fast.
NASA astronaut Scott Kelly, who is living aboard the International Space Station (ISS) on a one-year mission, wants to test your knowledge of the world with a geography trivia game on Twitter.
The first person to correctly identify the place depicted in his photos will win a copy of the picture signed by Kelly after he returns to Earth in March, 2016.
Kelly's first game post was on Earth Day, April 22, and he plans to continue the game for the duration of his mission.
Kelly launched to the space station along with Russian cosmonauts Mikhail Korniyenko and Gennady Padalka on March 27.
"Expanding our geography knowledge is essential to our economic well being, our relationships with other nations and also the environment," Kelly noted.
During his stay in ISS, part of Kelly's job is to capture a kaleidoscope of geographic locations for scientific analysis of our planet.
