"The international space station's research capabilities are now available after years of construction and $100 billion of investment. It offers opportunities to conduct research in an environment unavailable on Earth and it must be sustained, but not just for the sake of science. One problem in the president's proposal is that it does not address the risk to the station that will result from retiring the space shuttle and canceling the Constellation replacement program at the same time. A healthy and viable space station is critical to the emergence of the commercial space industry that the president's proposal relies on. If the space station is lost, the primary reason to send humans into space in the next decade will be lost."
"While we are encouraged the president showed a willingness to make some changes to his proposal for NASA during his visit to Florida, members of Congress from both parties still have concerns. These concerns include the readiness of the commercial space industry to fill the role the president envisions, and how to minimize the risk to the International Space Station, which after more than a decade of construction and $100 billion in investment is about to realize its full research potential."
