"As Chairman of the U.S. Senate Committee on Commerce, Science, and Transportation, Senator McCain played a major role in legislation to provide funding for space exploration (manned and unmanned), space science, Earth science, and aeronautics research. He also sponsored legislation to support the up and coming commercial space industry, and led the Senate's efforts to implement improvements to NASA after the Columbia accident. Senator McCain has also spearheaded efforts to control costs at NASA and promote a space exploration agenda based on sound management, safe practices, and fiscal responsibility.

As President, John McCain will -

Ensure that space exploration is top priority and that the U.S. remains a leader;

Commit to funding the NASA Constellation program to ensure it has the resources it needs to begin a new era of human space exploration.

Review and explore all options to ensure U.S. access to space by minimizing the gap between the termination of the Space Shuttle and the availability of its replacement vehicle;

Ensure the national space workforce is maintained and fully utilized; Complete construction of the ISS National Laboratory;

Seek to maximize the research capability and commercialization possibilities of the ISS National Laboratory;

Maintain infrastructure investments in Earth-monitoring satellites and support systems;

Seek to maintain the nation's space infrastructure;

Prevent wasteful earmarks from diverting precious resources from critical scientific research;

Ensure adequate investments in aeronautics research. "]

Obama (best points imho):

"As president, Barack Obama will establish a robust and balanced civilian space program. His NASA not only will inspire the world with both human and robotic space exploration, but also will again lead in confronting the challenges we face here on Earth, including global climate change, energy independence, and aeronautics research. In achieving this vision, Obama will reach out to include international partners and to engage the private sector to amplify NASA's reach. Obama believes that a revitalized NASA can help America maintain its innovation edge and contribute to American economic growth."

And..
A COMPREHENSIVE VISION
As president, Barack Obama will establish a robust and balanced civilian space program. His NASA not only will inspire the world with both human and robotic space exploration, but also will again lead in confronting the challenges we face here on Earth, including global climate change, energy independence, and aeronautics research. In achieving this vision, Obama will reach out to include international partners and to engage the private sector to amplify NASA's reach. Obama believes that a revitalized NASA can help America maintain its innovation edge and contribute to American economic growth

There is currently no organizational authority in the Federal government with a sufficiently broad mandate to oversee a comprehensive and integrated strategy and policy dealing with all aspects of the government's space- related programs, including those being managed by NASA, the Department of Defense, the National Reconnaissance Office, the Commerce Department, the Transportation Department, and other federal agencies. This wasn't always the case. Between 1958 and 1973, the National Aeronautics and Space Council oversaw the entire space arena for four presidents; the Council was briefly revived from 1989 to 1992. Barack Obama will re-establish this Council reporting to the president. It will oversee and coordinate civilian, military, commercial and national security space activities. It will solicit public participation, engage the international community, and work toward a 21st century vision of space that constantly pushes the envelope on new technologies as it pursues a balanced national portfolio that expands our reach into the heavens and improves life here on Earth.

SPACE SCIENCE AND EXPLORATION
Closing the Gap
Since 1981, the Space Shuttle has been NASA's workhorse. Its retirement will leave NASA without human spaceflight capability until the first elements of the Constellation program are operational, some five years later. This gap between the retirement of the Space Shuttle and the entry into service of its replacement is a serious concern. Barack Obama is committed to making the necessary investments to ensure we close this gap as much as is technically feasible and to minimize reliance on foreign space capabilities. He also will work with the space industry to ensure retention of workforce and technical capabilities during the transition from the shuttle to its successor.

Retaining Options for Additional Shuttle Flights: Barack Obama supports Congressional efforts to add at least one additional Space Shuttle flight to fly a valuable mission and to keep the workforce engaged. He will work to ensure there is adequate funding to support that additional flight so that it does not interfere with developing the Shuttle's successor.

Speeding the Next-Generation Vehicle: Obama will expedite the development of the Shuttle's successor systems for carrying Americans to space so we can minimize the gap. This will be difficult; underfunding by the Bush administration has left NASA with limited flexibility to accelerate the development of the new systems.

Using the Private Sector: Obama will stimulate efforts within the private sector to develop and demonstrate spaceflight capabilities. NASA's Commercial Orbital Transportation Services is a good model of government/industry collaboration.

Working with International Allies: Obama will enlist international partners to provide International Space Station (ISS) cargo re-supply and eventually alternate means for sending crews to the ISS.
Help The Planetary Society set the tone for the next administration's space policy!

Completing and Enhancing the International Space Station
The International Space Station is an outstanding example of what can be accomplished through international cooperation. Though we have spent billions to build the station, the microgravity research it was intended to facilitate has fallen victim to funding cuts. Barack Obama would ensure that NASA and other federal agencies are fully utilizing the ISS to conduct research that can help address global challenges such as public health and energy independence and can develop technologies that can provide economic benefits to Earth. Obama also will enable research on the ISS to support long-term human exploration and planetary research needs.

Partnering to Enhance the Potential of the ISS: Barack Obama will enlist other Federal agencies, industry and academia to develop innovative scientific and technological research projects on the ISS. "

Of course there's more of the same there.

Sorry, in short and if you were looking for an oppinion, I think that McCain wins this one because it seems like it is the one that is actually looking for change and he's been long enough to know better.

Well, you asked.
