Remembering Fallen Pioneers

NASA, the nation and the world are observing this  week the anniversaries of human losses in spaceflight: Apollo 1 (forty  eight years ago today, January 27), Challenger (twenty nine years  ago tomorrow, January 28), and Columbia (twelve years ago this coming Sunday,  February 1).

May they be always remembered, along with the four Russians, the Virgin Galactic SpaceShipTwo pilot and all those who have or will give their lives in the future as humans expand outward to explore, develop and settle new places in the cosmos.
