Houston, we have a problem.

--Jim Lovell

Yesterday was also the day of Nasa's Day of Remembrance.

Let us reflect on those who have given their lives in the US Space program. From Apollo I to the Shuttle Challenger to the Shuttle Columbia, tragedy has stalked our first faltering steps into space.. The individuals in the space program are involved in a great and noble mission. Throughout the ages, explorers have understood the risks of venturing into unknown territory. As man pushes into the frontier of space, it is certain that more tragedy will lie ahead. All the same, there are triumphs to come as well.

In the meantime, let us remember.
