Blue Origin's lunar lander just passed its toughest test yet

There is a chamber at NASA's Johnson Space Center in Houston that is, in its own way, one of the most extraordinary rooms on Earth. Chamber A is one of the largest thermal vacuum facilities in the world, a vast steel vessel that can recreate the airless, temperature swinging brutality of space without leaving the ground. It has tested spacecraft destined for the moon, for the planets, and for the deep dark between them. Now it has tested Blue Origin's Blue Moon Mark 1 lunar lander, known as Endurance, and the vehicle has passed with flying colors.
