Just to note, re Ken's initial reply, and some of the subsequent 
discussion, that, controversially, NASA's mission was altered twice during 
the Bush years:
so, first it was quietly added in 2002 to its mission (which had been much 
as Ken says) that it was also "to understand and protect" the earth, but 
then this was removed, in 2006, making quite a stir........it was an 
intentional swipe at climate science, surely.....probably something Obama 
could reverse very easily....

It would certainly make tons of sense to have a drive now to quickly 
reverse this mission change, yet again.....and then - whether Ron is right 
or not about doing things best 
in a widely diversified way, given the nature of the climate beast -  let 
NASA be a "billboard" player & show off its new protector prowess by 
removing 10 or 15Gt/yr through various CDR techniques.......

cheers, Nathan

here's from Union of Concerned Scientists on NASA mission - 

At NASA, Earth is Removed from Mission Statement

In February 2006, the phrase "to understand and protect the home planet" 
was quietly removed from the National Aeronautics and Space Administration 
(NASA)'s official mission statement. Because agency mission statements are 
routinely used to justify research and funding decisions, many scientists 
were not only surprised to discover the change, but also concerned that the 
change meant more funding would be shifted away from studies of Earth, 
including climate change research, and redirected to NASA's planned new 
series of manned space missions.

A NASA atmospheric chemist commented, “We refer to the mission statement in 
all our research proposals that go out for peer review…as civil servants, 
we’re paid to carry out NASA’s mission. When there was that very 
easy-to-understand statement that our job is to protect the planet that 
made it much easier to justify this kind of work.”1  NASA scientists 
responding to a Union of Concerned Scientists survey also expressed 
concerns that changing priorities and lack of funding were seriously 
undermining the agency’s ability to continue with high-quality research 
into climate change.2 

The agency’s current mission statement calls on the agency “to pioneer the 
future in space exploration, scientific discovery and aeronautics research.”
3  It is the first time since NASA’s founding in 1958 that the mission 
statement does not explicitly include mention of the Earth. A NASA 
spokesperson was quoted in the New York Times as saying that the mission 
statement was rewritten “to square the statement with President Bush’s goal 
of pursuing human spaceflight to the Moon and Mars.”4 

Scientists’ funding fears are already more than hypothetical. A 2006 report 
by the National Research Council (NRC, a part of the National Academy of 
Sciences), noted that funding cuts currently in place at NASA will mean 
canceling or not replacing several of the agency’s Earth observation 
satellites. This will, in the words of the NRC report, cause a “severe 
deficit” in Earth observation capabilities and compromise the government’s 
ability to “fulfill its obligations in . . . [the] Climate Change Science 
Program”5 

NASA’s previous mission statement was adopted in 2002 in an open process 
with input from across NASA’s 19,000 employees. In contrast, NASA 
researchers said the new mission was revised with no discussion or public 
announcement of any kind.6
