President George W. Bush announced Friday the business leaders, scientists and other spaceflight experts who will advise him on how to carry out the specifics of his new vision for putting humans back on the Moon and eventually on Mars.

Other members of the commission: Michael P. Jackson of Virginia, Laurie Ann Leshin of Arizona, Lester L. Lyles of Ohio and Robert Smith Walker of Pennsylvania.

The panel will advise the White House on what sort of science agenda should be considered for the Moon and other destinations as well as what human and robotic missions should be conducted to achieve Bush's vision.

The president said robots would return to the Moon around 2008, followed by the first humans by 2020. A permanent lunar base would then serve as a test bed to prepare for the first human mission to Mars. Bush outlined a pay-as-you-go approach, rather than asking for Apollo-era increases in the NASA budget.

The first budget request containing specifics related to the new plan is due out this week, when the 2005 budget request from the White House is presented. Officials say NASA's portion of the $2.2 trillion federal budget will be $16.2 billion in 2005, up from $15.5 billion in 2004. Some $1.09 billion of the new request will be targeted at fulfilling the Bush vision. Eventually, more money will be redirected from the space shuttle and international space station programs.

The 2005 budget request, as well as the components of the president's plan, must be approved by Congress for NASA to pursue the lofty goals.

The president said during his Jan. 14 speech that the new commission would advise him on the details for carrying out the vision and that continual revision of NASA's spaceflight plans would be made as costs were evaluated and technology developed.

The team members will consider which technologies to employ and how, strategically, to use resources on the Moon to accomplish the goals of extending the human presence in space, according to a White House statement.

"The most appropriate and effective roles for potential private sector and international participants" must also be weighed, Bush said in the statement, as well "methods for optimizing space exploration activities to encourage the interest of America's youth in studying and pursuing careers in mathematics, science, and engineering."

NASA is to fund the commission and provide administrative support. The members will serve without pay but will have their travel and other expenses covered. They are to report to the president within 120 days of their first meeting, according to a White House press statement.

The commission has been instructed to solicit views and opinions from the public, academia, and industry.
