During the year, Steidle's office developed a timetable for the moon-Mars initiative, mapped its priorities and gathered experts to chop the project into contract-size pieces. By Thanksgiving, the agency had let more than 120 contracts.
The plan's early centerpiece is the next-generation "Crew Exploration Vehicle," designed to fly by 2014 and to reach the moon by 2020. NASA received about 1,000 responses to its initial request for "concepts" of what the vehicle should be.
"We selected 11 teams, and next August we're going to reduce them to two, or maybe three, who will actually build a vehicle, test and demonstrate it [without a crew] in 2008," Steidle said in an interview at NASA headquarters.
For the plan's other needs, NASA has vetted more than 3,700 proposals to provide technologies including navigation systems, tools and machinery. Caterpillar Inc. of Peoria, Ill., will provide equipment for doing construction on the moon, and Hamilton Sunstrand of Windsor Locks, Conn., will develop new techniques to reclaim water from human waste.
NASA next must pick a rocket system for launching the vehicle, and "we're looking at everything," Steidle said. In a few months, the agency will decide whether to use a single, "shuttle-derived" heavy launch rocket, a smaller spacecraft or a combination. The hybrid would put the crew exploration vehicle and a supplementary rocket into orbit separately, where they would link up for the lunar flight.
NASA projects that Bush's plan will cost $100 billion by 2020, and Steidle said, "I feel very good about" being able to deliver a crew vehicle by 2014 with "the money that's in the budget right now. What's beyond gets a little foggy."
But not excessive. "It's not like building a space station," NASA Comptroller Steven J. Isakowitz said in a telephone interview. "Costs are more manageable" because the new spaceship is the only major piece of hardware scheduled for construction in the next decade.
Some in Congress were not convinced. On June 20, the House Appropriations subcommittee charged with funding NASA trimmed Bush's 2005 budget request by $1.1 billion and eliminated all $438 million slated for the crew exploration vehicle.
"It was about the money," recalled subcommittee Chairman James T. Walsh (R-N.Y.). "I remember Sean [O'Keefe] coming in and trying to give people a comfort level, but the budget we had to work with didn't even come close."
Three days later, White House budget director Joshua B. Bolten sent a letter threatening a veto unless the bill gave the plan "adequate funding levels." DeLay had visited the White House hours earlier.
The bill never reached the House floor, but if Walsh wanted to get higher-ups to focus on it, he had succeeded. "We created the atmosphere where people could come to our rescue," Walsh said.
But it took awhile. In September the nonpartisan Congressional Budget Office released a report suggesting that NASA intended to fund the president's plan in part by taking $10 billion from signature science programs such as the one that produced the Mars rovers.
NASA's Isakowitz said most of the reallocations resulted from shifting control of existing programs to Steidle's office, not canceling them. For instance, he said, the Office of Explorations absorbed Project Prometheus, a $400 million-a-year program to develop nuclear power for space use.
Still, Isakowitz acknowledged that NASA has delayed start-up or funding increases for some science projects in order to fund Bush's plan. These will bring the plan $2.7 billion from 2005 to 2009.
The projects affected are mostly in two areas: "Beyond Einstein," astrophysics missions, and "Explorers," extremely competitive small missions usually focused on astronomy and the history of the universe.
Concerns about funding and priorities remained unresolved into the autumn, but Bush's reelection gave the administration a political boost. In a post-election interview, O'Keefe said he was "feeling better every day" about the plan's budget and "supremely confident" that it would be passed as written.
And so it proved. NASA was identified as a major sticking point when Senate and House conferees sat down to craft the final version of the omnibus spending bill near midnight Nov. 19, but Bolten, Senate Appropriations Committee Chairman Ted Stevens (R-Alaska) and DeLay were holding out for more money.
The negotiators appeared to agree on $15.9 billion for NASA, but that wasn't good enough, DeLay said later at the Space Center. "The main responsibility of the majority leader is to set the agenda for the House floor. I wouldn't schedule the bill until NASA was taken care of," he said.
And it was.
"Once you get into an omnibus bill, the leadership takes over, and you need to have an advocate in that circle," Walsh said. DeLay "was getting me more allocation every time he stepped up to the plate. He made the difference."
