NASA astronaut Scott Kelly on the International Space Station July 8, 2015 tweeted this image out of an Earth observation as part of his Space Geo trivia contest. Scott tweeted this comment and clue: "#SpaceGeo The root of this peninsula's name means "tooth" referencing its mountain peaks & triangular shape Name it!" Congratulations to @S3TOK for correctly identifying this image as the Sinai Peninsula first. He will receive an autographed copy of this image when Scott returns to Earth in March 2016.
