NASASpaceflight: Managers preparing for July 8 SLS announcement after SD HLV victory
Managers preparing for July 8 SLS announcement after SD HLV victory
Following an intense week of executive level reviews, a decision has been made on the configuration for NASA’s new launch vehicle. With NASA administrator Charlie Bolden agreeing to a configuration which is heavily derived from the retiring Space Shuttle, an official announcement is likely to be made on July 8, coinciding with the Shuttle’s final launch date.

"As a former astronaut and the current NASA Administrator, I'm here to tell you that American leadership in space will continue for at least the next half-century because we have laid the foundation for success -- and failure is not an option."
Charles Bolden, NASA Administrator

[/SIZE][/FONT]United Launch Alliance and NASA will share technical data to help ready the company's Atlas 5 rocket for astronaut passengers, officials announced Monday.

[/SIZE][/FONT]The agreement places the Atlas 5 rocket among the top competitors to launch the next piloted spacecraft from U.S. soil after the retirement of the space shuttle. "I am truly excited about the addition of ULA to NASA's Commercial Crew Development program team," said NASA Administrator Charlie Bolden. "Having ULA on board may speed the development of a commercial crew transportation system for the International Space Station, allowing NASA to concentrate its resources on exploring beyond low Earth orbit."
Colorado-based United Launch Alliance was passed over in NASA's last Commercial Crew Development, or CCDev, competition. When the agency announced the winners in April, officials said they gave priority to spacecraft developers because rockets would take less time to modify for manned flights.
NASA divided $270 million among four companies in the April announcement, giving $92.3 million to Boeing, $80 million to Sierra Nevada Corp., $75 million to SpaceX and $22 million to Blue Origin. The competition was the second round of NASA's CCDev program, which provides federal funding to U.S. space companies building commercial human-rated spacecraft.
All of the winners are designing spacecraft to carry astronauts to and from low Earth orbit destinations such as the International Space Station.
But the space vehicles will need rockets to send them into orbit. Boeing, Sierra Nevada and Blue Origin could launch their spacecraft on ULA rockets.
Sierra Nevada and Blue Origin have selected the Atlas 5 rocket to launch their spaceships. Sierra Nevada is working on a lifting body space plane named the Dream Chaser and Blue Origin, headed by Amazon.com founder Jeff Bezos, is developing a biconic capsule called the New Shepard.

Boeing's CST-100 spaceship is designed to ferry up to seven astronauts to and from orbit. The company says the craft is compatible to launch on several rockets, including the Atlas 5, but managers plan to select a primary launch vehicle in the coming weeks, according to a Boeing spokesperson.
Boasting a stellar success record, the Atlas 5 rocket has launched 26 times with U.S. military payloads, NASA science probes and commercial communications satellites. The Atlas 5's first stage is powered by a kerosene-fueled Russian RD-180 main engine, and its Centaur second stage features one or two RL10 engines burning cryogenic propellant.
SpaceX will launch its Dragon capsule on the company's own Falcon 9 rocket.
NASA's agreement with ULA doesn't provide any funding, but it facilitates data sharing among the two entities. Under the agreement, ULA will provide technical data on the Atlas 5 rocket to NASA, which will give input based on the agency's extensive human spaceflight experience.
The space agency will also share draft human-rating certification requirements for ULA to review and provide feedback.
ULA says it will continue design and analysis of its plans to outfit the Atlas 5 for human crews, conduct program reviews, develop a hazard analysis, complete a probabilistic risk assessment, conduct a systems requirements review, and accomplish several other milestones. The company will pay for the continued design work without any NASA money.
A new schedule, created by NASA, has provided a “preliminary, budget restricted” manifest which places the first flight of the fully evolved Space Launch System (SLS) in the year 2032. The information includes details on the chosen configuration and hardware, but provides a depressing schedule, with a flight rate of just one mission per year, after a staggered opening which results in SLS-2 waiting until 2021 to launch.

Preliminary NASA plan shows Evolved SLS vehicle is 21 years away
A new schedule, created by NASA, has provided a “preliminary, budget restricted” manifest which places the first flight of the fully evolved Space Launch System (SLS) in the year 2032. The information includes details on the chosen configuration and hardware, but provides a depressing schedule, with a flight rate of just one mission per year, after a staggered opening which results in SLS-2 waiting until 2021 to launch.
Initially, the call was to debut the SLS in 2016. As recently noted, the schedule for the opening flight has moved to December 2017 – although it now has an actual mission.
The mission will be lunar, with SLS-1 lofting Orion (MPCV) on an unmanned mission around the Moon.
Ironically, SpaceX recently noted – during their Falcon Heavy announcement – they are close to such a mission capability, far sooner than 2017.
MOUNTAIN VIEW, Calif. — Despite concerns that funding shortfalls will hamper NASA's efforts to promote a private industry capable of ferrying cargo and crew into low Earth orbit, government and industry officials attending the Space Frontier Foundation's annual conference said they were confident that commercial firms would continue to play an increasingly important role in the U.S. space program.
NASA officials are working diligently "on evolving the way we work with the private sector," Deputy Administrator Lori Garver said July 28 at the NewSpace 2011 conference here.
While the overall percentage of NASA's budget going to the private sector is likely to remain at the current level of approximately 85 percent, the space agency is changing the way it spends that money in an effort to help private companies "leverage that money to bring in more private investment, more innovation, open new markets, reduce costs and provide economic gain."

"America is opening a bold new chapter in human space exploration," NASA Administrator Charles Bolden said in a news release. "By combining the resources of Space Operations and Exploration Systems, and creating the Human Exploration and Operations Mission Directorate, we are recommitting ourselves to American leadership in space for years to come."
