NASA began developing the Space Launch System (SLS) in earnest when the Space Shuttle program ended in 2011. This super-heavy-lift rocket will be key to NASA's return to the moon, but the escalating costs have some inside and outside the agency concerned. The Government Accountability Office...
For comparison, Quilty estimated that the space shuttle cost $1.75 billion per launch when adjusted for inflation — more than four times as much. NASA even said it expects the Commercial Crew program will save U.S. taxpayers more than $20 billion compared to the agency's previously plan for...
Space shuttle missions cost about 450 million dollars per launch, and while that sounds like a lot more than SpaceX's price of $133 million, 航天飞机执行一次任务的成本约为4.5亿美元,虽然听起来远比SpaceX的发射费用1.33亿美元高不少, you have to remember the Space Shuttle was a beast of a ...
Hubble's planned liftoff was delayed again after thespace shuttle Challenger explodeda minute after takeoff on Jan. 28, 1986, killing all seven astronauts on board. It was more than 2.5 years before shuttle flights resumed and NASA could begin planning Hubble's launch again. ...

Between 1970 and 2000, the cost to launch a kilogram to space remained fairly steady, with an average of US$18,500 per kilogram. When the space shuttle was in operation, it could launch a payload of 27,500 kilograms for $1.5 billion, or $54,500 per kilogram. For a SpaceX Falcon 9...

The shuttles are generally considered to provide the best prospect of lower-cost access to space. The reusable launch vehicle is capable of launching more than one payload into space and can transport more cargo than a single-use craft. Each shuttle's cargo bay is designed to have a lifetime...
The launch and its low cost were a source of immense pride in India, which beat rival China in becoming the first Asian country to reach the Red Planet. K. Sivan, a scientist involved in the latest project, said the seven-metre (23-foot) long shuttle survived the test flight, and scie...
