NASA allocating 1.6B to private sector for space taxi.
NASA on Monday unveiled a plan that will allocate $1.61 billion to private companies that will transport U.S. astronauts to the International Space Station and low Earth orbit.
The program, which will run from July 2012 to April 2014, will provide funds to multiple companies, which must design and maintain spacecraft, launch vehicles, launch services, ground and mission operations, and recovery.
"This is a significant step forward in America's amazing story of space exploration," NASA Administrator Charles Bolden said in a statement. "It's further evidence we are committed to fully implementing our plan—as laid out in the Authorization Act—to outsource our space station transportation so NASA can focus its energy and resources on deep space exploration."
NASA retired its space shuttle fleet over the summer and has since relied on Russian spacecraft to get its astronauts to the ISS (at a price of $50 million per person). During the most recent Soyuz landing, however, communications between the landing craft and Russia's Roscosmos space agency broke down for several minutes after the Soyuz capsule had de-orbited. Contact was re-established before landing and no one was injured, but the "space taxis" announced by NASA this week gives the agency another option for getting its astronauts to the ISS.
The effort, known as Integrated Design Contract (IDC) "will bring us through the critical design phase to fully incorporate our human spaceflight safety requirements and NASA's International Space Station mission needs," said NASA Commercial Crew Program Manager Ed Mango. "We look forward to strong U.S. industry response."
To push development, NASA also said it will fund some optional programs negotiated as add-ons to existing Commercial Crew Development (CCDev2) Space Act Agreements (SAA) initially awarded in April. Specifically, Sierra Nevada Corp. will get $25.6 million for a total of $105.6 million, while Boeing will take home another $20.6 million for a total of $112.9 million. Space Exploration Technologies/SpaceX and Blue Origin have also been awarded contracts.
"All four CCDev2 partners are performing very well and meeting their milestones," said Phil McAlister, director of NASA's Commercial Spaceflight Development. "These additional milestones were selected because they sufficiently accelerated the development of commercial crew transportation systems to justify additional NASA investment."

NASA wants to build most powerful rocket ever - but if wishes were horses -beggars would be riders...
WASHINGTON (AP) — To soar far away from Earth and even on to Mars, NASA has dreamed up the world's most powerful rocket, a behemoth that borrows from the workhorse liquid-fuel rockets that sent Apollo missions into space four decades ago.
But with a price tag that some estimate at $35 billion, it may not fly with Congress.
NASA Administrator Charles Bolden and several members of Congress on Wednesday unveiled the Obama administration's much-delayed general plans for its rocket design, called the Space Launch System. The multibillion-dollar program would carry astronauts in a capsule on top, and the first mission would be 10 years off if all goes as planned. Unmanned test launches are expected from Cape Canaveral, Fla., in six years.
Calling it the "largest, most powerful rocket built," NASA's exploration and operations chief, William Gerstenmaier, said the rocket will be tough to construct. But when NASA does it, "we'll have a capability to go beyond low-Earth orbit like no other nation does here on Earth," he said in a telephone briefing Wednesday.
The rocket resembles those NASA relied on before the space shuttle, but even its smallest early prototype will have 10 percent more thrust than the Saturn V that propelled Apollo astronauts to the moon. When it is built to its fuller size, it will be 20 percent more powerful, Gerstenmaier said. That bigger version will have the horsepower of 208,000 Corvette engines.
NASA is trying to remain flexible on where it wants to go and when. The space agency is aiming for a nearby asteroid around 2025 and then on to Mars in the 2030s. There could even be a short hop to the moon, but not as a main goal. All those targets require lots of brute force to escape Earth's orbit, something astronauts have not done since 1972.
The far-from-finalized price tag may be too steep given federal budget constraints.
"Will it be tough times going forward? Of course it is," Sen. Bill Nelson, D-Fla., said in a separate news conference. "We are in an era in which we have to do more with less — all across the board — and the competition for the available dollars will be fierce. But what we have here now are the realistic costs" verified by independent experts.
Although five senators of both parties who are leaders in science issues praised the plan in a joint press release, outside experts are skeptical that Congress will agree to such a big spending project.
"In the current political environment, new spending is probably the most taboo thing in politics," said Stan Collender, a former Democratic congressional budget analyst. He put the odds of this getting congressional approval at "no better than 50-50 this year. There are going to be a lot of questions asking what kind of commitment we're going to be making here. You can find yourself with a rocket that no one wants to fire."
Nelson puts the cost of the program at about $18 billion over the next five years. But that estimate is mostly for development and design through the first test flight in 2017, and doesn't include production of later rockets, Gerstenmaier said. Gerstenmaier wouldn't give a total estimate, but it is almost double that, according to senior administration officials, who spoke on the condition of anonymity because they were not authorized to make the announcement.

Bastrop is burning ...
BASTROP
- The most destructive wildfire on record in Texas showed no signs of slowing down Monday, destroying 25,000 acres in Bastrop County and 476 homes, more houses than any single wildfire before and more than all other fires this year combined, according to the Texas Forest Service.
With more than 60 new wildfires raging across the state, Gov. Rick Perry left the campaign trail Monday in South Carolina to address the public and organize requests for more federal aid.
Closer to Houston, a fire in Magnolia burned 20 homes and more than 1,600 acres, and was threatening subdivisions in Montgomery and Grimes counties late Monday. It had moved southwest into Waller County last Monday.
It was one of several fires to hit the area, straining state and local resources as officials focused on the most dangerous blazes. One firefighter was injured and one fire engine burned in blazes in the Magnolia area, said Lt. Dan Norris, spokesman for the Montgomery County Sheriff's Office.
Authorities did not yet know how much of the most dangerous fire had been contained Monday, but planned to continue fighting it "as long as necessary," Norris said.
Strong winds and dry conditions fanned the flames and aided the blaze's rapid growth, forcing the evacuation of more than 150 homes. Montgomery County officials were encouraging evacuations from the intersection of FM 1774 and FM 1488, about 42 miles northwest of Houston, up to the Grimes County line, an official said.
Magnolia fire
The Magnolia fire, located off FM 1774 and FM 1488, jumped FM 1488 late Monday and forced further evacuations, although some families were being allowed back to their homes. The Magnolia Independent School District canceled classes today because of the fires. Evacuation shelters were being set up throughout the area, including at Magnolia High School.
Another fire in the area had burned 100 acres and was 80 percent contained, Norris said. It had destroyed one structure and caused no injuries after 50 homes were evacuated.
A fire covering about 100 acres was burning in Oak Ridge North late Monday.
A fire near Nacogdoches that started Sunday night raged to 300 acres Monday and forced 60 families to evacuate their homes, said Ralph Cullom, a spokesman for the Texas Forrest Service. That fires grew with strong gusts of winds and fed off of dry conditions on the ground.
"This drought we're having is just unprecedented," Cullom said.
No injuries have been reported in Bastrop, but two people were reported killed in a North Texas fire Monday. A woman and her 18-month-old child died when a fast-moving fire near Gladewater, east of Dallas, set their mobile home on fire and they were unable to escape.
The Bastrop County Complex Fire, pushed by strong winds and fed by plenty of dry grasses, shrubs and trees, steadily moved south Monday and expanded throughout the day. It jumped the Colorado River twice.
"We will be working days on end," said Mike Fisher, the Bastrop County Emergency Management Coordinator. "The fire is so dynamic we really have no idea where it is."
'Lives at stake'
Perry said the wildfire burning in the central part of the state is "as mean looking" as he's ever seen.
