How big are the stations ammonia pumps and how much do they cost?
The space station crew has said the size of the pumps is similar to a laundry dryer. Each pump weighs 780 pounds (353 kg) and is 5 1/2 feet long (69 inches) by 4 feet wide (50 inches). They are about 3 feet tall (36 inches). NASA doesn’t have an official cost for each of the ammonia pumps on the space station. But a spare pump assembled on the ground in 2009 cost about $3.9 million, NASA officials told SPACE.com.
