Alliant wins NASA contract

By Zacks Equity Research

 

Alliant Techsystems Inc. (ATK) has received a contract worth $50 million from the National Aeronautics and Space Administration (NASA) to complete its engineering development and risk- reduction examinations as a part of the Advanced Concept Booster Development for the Space Launch System (SLS).

According to the contract, Alliant will help NASA to manage important technological challenges during manufacturing of advanced booster requirements for its SLS program. The company will use cost-saving materials and procedures to develop a lithium-ion battery-powered electric thrust vector control system, lightweight composite rocket motor case, high-performance propellant and an advanced nozzle. These advancements will conclude with a combined booster static test firing of these utilized technologies.

The U.S. SLS will offer a completely new facility for human exploration beyond earth orbit. In addition, it will support the commercial as well as international transportation service partners to the International Space Station. This system is designed to be safe, flexible and affordable for crew or cargo missions to continue the U.S.s journey toward space discovery.

Driven by the installation of this modern technology including advanced booster design, NASA will help in reducing the cost of operations while minimizing risks under its SLS system program. In addition, this new initiative will provide higher reliability and greater performance than current NASA requirements, and will subsequently help to boost the capability of NASA’s heavy launch system.

Alliant and NASA jointly took few initiatives to minimize costs related to the SLS system. The company has already made significant progress toward developing the first ground test motor and advancements of cost-saving processes for manufacturing solid rocket booster for SLS system. The company primarily uses Value Stream Mapping (VSM) process, which helps to recognize incompetent processes and requirements of the system. Utilizing this process, the company spotted more than 400 changes and improvements, which have already received NASA approvals.

The Arlington, Virginia company provides aerospace and defense products to the U.S. government agencies. The company also supplies ammunition and related accessories to law enforcement agencies and commercial customers. Alliant currently has a short-term Zacks No. 2 Rank (“buy” rating) and competes with Rockwell Collins Inc. (COL) and Elbit Systems Ltd. (ESLT).

Even as ATK streamlines, more layoffs loom in 2013

Promontory • Utah aeronautical contractor Alliant Techsystems says it has streamlined its process of making booster rockets, while also acknowledging Tuesday that it will have to lay off more workers early next year.

The company will be reducing the number of its employees by an untold number in February in response to its anticipated workload, said Charlie Precourt, ATK’s vice president and general manager for the Space Launch System (SLS).

NASA awards ATK new contract

As Alliant Techsystems retools its process of manufacturing booster rockets for NASA’s Space Launch System (SLS), it already is looking ahead to the next generation of its rockets.

ATK was awarded a $51 million contract earlier this week to demonstrate new technologies for the next version of its booster rocket for a new launch system.

The boosters will be built from a composite case, and have a new nozzle and higher-performing propellant, said ATK spokeswoman Trina Helquist. The first ground test won’t be conducted for a couple of years.

ATK was one of three aeronautical companies awarded NASA contracts totaling $137 million. The other two were e Dynetics Inc. of Huntsville, Ala., and Northrop Grumman Corp. Aerospace Systems of Redondo Beach, Calif.

The new 77-ton launch system will use two five-segment solid rocket boosters similar to those used for the space shuttle, according to NASA.

“We don’t know the exact number,” he said. “We’re striving every day to not make it be any, but we’re anticipating a small number.”

Precourt said the layoffs would be companywide in the rocket propulsion teams at Utah’s three ATK plants — in Promontory near Brigham City, and in Magna and Clearfield. ATK not only makes rocket boosters for NASA, but has a weapons division for the U.S. military and a sporting division that produces ammunition and shooting accessories for sports shooting and law enforcement. The operations for the latter are largely based outside Utah. The company employs about 2,500 workers in Utah, and about 600 work on the NASA SLS, which is powered by ATK’s solid rocket boosters.

Although Precourt would not say how many job losses there will be, he insisted they are not part of the stream of layoffs that occurred in the past 31/2 years, which were largely related to the end of the space shuttle program and resulted in more than 2,000 employees being cut. He added that ATK employees already know about the pending layoffs.

Precourt also said the upcoming reduction was not a part of the company’s recent effort to streamline its manufacturing of rocket boosters, a process it calls “value stream mapping.”

With the help of NASA, ATK was able to identify areas where there were redundancies and made upgrades to its manufacturing and testing to improve the time and cost of making its boosters for its space launch system. NASA’s SLS will launch future rockets into space for human exploration. It can be used to launch rockets for both crew and cargo missions.

With the approximately 400 changes made to the process, which took a year to implement, the company can save as much as 46 percent of the assembly time, as well as millions of dollars in projected costs.

Although the process is reducing costs and eliminating unnecessary steps in producing the boosters, Precourt said that does not mean the company is taking shortcuts. He said the steps have not affected the safety of the rockets or increased their risks.

“We have a lot of opportunity to test and validate [their safety],” he said.

Although NASA would not say whether the changes would make ATK more competitive for future contracts, “what it does do is show ATK’s dedication to human space flight and exploration, and to take on the hard challenge to live within the tough budget constraints,” said Dan Dumbacher, a deputy associate administrator for the space agency.

In August, ATK lost out on a multimillion-dollar contract to use its Liberty rocket system to shuttle cargo and crew to the International Space Station. Instead, contracts went to Boeing Co., Space Exploration Technologies Corp. and Sierra Nevada Corp. ATK officials are evaluating how the company can use its Liberty system for future space travel.

Boeing, SpaceX and Sierra Nevada to win NASA backing for spaceships

NASA

Sources tell NBC News that NASA will provide further support for the development of the Boeing Co.’s CST-100 capsule (left), Sierra Nevada Corp.’s Dream Chaser space plane (middle) and SpaceX’s Dragon capsule (right).

Teams headed by the Boeing Co., SpaceX and Sierra Nevada Corp. will be receiving hundreds of millions of dollars from NASA over the next 21 months for further development of spaceships capable of transporting astronauts to and from the International Space Station, knowledgeable sources told NBC News today.

NASA is to make the official announcement of the winning commercial teams on Friday morning — but NBC News’ Cape Canaveral correspondent, Jay Barbree, received word from two sources who were informed of the decision in advance, on condition of anonymity. The sources did not discuss how much money any of the companies would be receiving.


The coming phase of the spaceship development effort — known as Commercial Crew Integrated Capability, or CCiCap — is aimed at producing the design for an entire launch system, including the “space taxi” capsule and launch vehicle as well as ground and recovery operations. The three companies tapped for future funding already have received hundreds of millions of dollars from NASA during earlier development phases. Boeing has gotten $131 million for work on its proposed CST-100 capsule, Sierra Nevada has been allotted more than $125 million for its Dream Chaser space plane, and SpaceX has won $75 million to upgrade its Dragon space capsule to carry crew.

SpaceX, known more formally as Space Exploration Technologies, has also received almost $400 million from a separate NASA program to support the development of the Dragon and Falcon 9 rocket for cargo deliveries to the space station. The successful flight of a Dragon to the station and back in May opened up the way for SpaceX to start regular cargo deliveries under a $1.6 billion contract with NASA.

Representatives of SpaceX and Sierra Nevada had no comment on the news. NASA said it would not announce the agreements until Friday morning, as scheduled. Efforts to contact Boeing were unsuccessful so far tonight. The Wall Street Journal, meanwhile, quoted industry sources as saying that Boeing and SpaceX were expected to share the bulk of NASA’s CCiCap money, and that Sierra Nevada seemed likely to emerge with a smaller award.

NASA invited companies to submit proposals in the range of $300 million to $500 million for development of their spaceship designs through May 2014, with potential optional milestones as well. Under an agreement with congressional leaders, the space agency will provide the full negotiated amount for two companies, plus half of the requested funds for a third company. It’s an arrangement I like to call “Two and a Half Spacemen,” playing off the title of the popular CBS sitcom.

What about the also-rans?
Other companies sought unsuccessfully to win CCiCap funding — most prominently, a consortium that included ATK, Lockheed Martin and Astrium. The consortium’s Liberty launch system would adapt the ATK-manufactured solid rocket booster that was used for the space shuttle and the now-canceled Ares 1 rocket. The second stage would be based on Astrium’s Ariane rocket. The composite capsule would be provided by Lockheed Martin, which is the prime contractor for NASA’s more capable Orion deep-space capsule.

Other contenders from previous rounds of development included Blue Origin, which was founded by Amazon.com billionaire Jeff Bezos; and Excalibur Almaz, which is adapting Russian technology for its launch system.

NASA officials have said they’d be willing to continue advising the also-rans on an unfunded basis. On the other side of the table, all of the companies involved in the CCiCap competition have said they intended to continue spaceship development efforts even if they didn’t win NASA’s financial support, but at a reduced pace.

What lies ahead?
Boeing, SpaceX and Sierra Nevada have said their spaceships could be ready for NASA’s use in the 2015-2016 time frame if they received adequate funding from the space agency. Last month, Ed Mango, NASA’s manager for the Commercial Crew Program, told me that the middle of the decade seemed doable, but suggested that 2015 might be too soon.

“By the end of the base period, you need to have an integrated design that you have talked with the government about,” Mango said. Actually launching a demonstration spaceflight with a crew might serve as an optional milestone, he added.

Boeing and Sierra Nevada are partnering with other companies to develop their launch system — and the most notable partner in both cases is United Launch Alliance, which could launch Boeing’s CST-100 as well as Sierra Nevada’s Dream Chaser on its Atlas 5 rockets. SpaceX, in contrast, is pursuing its effort on a solo basis.

With last year’s retirement of the space shuttle fleet, NASA must depend on the Russians to transport U.S. astronauts to and from the space station, at a cost of around $60 million a seat. All of the companies involved in the Commercial Crew Program say they can do the job for less money than the Russians. In comparison, the cost of flying the space shuttle was estimated at $1 billion or more per mission.

Like the shuttle, the new space taxis are being designed to carry up to seven astronauts.

The commercial space taxis are an essential piece of the strategy worked out by the White House and NASA to free up money for the development of the Orion multipurpose crew vehicle as well as a heavy-lifting Space Launch System. The Orion and SLS would be used for exploration beyond Earth orbit, featuring trips to a near-Earth asteroid by 2025 and journeys to Mars and its moons in the 2030s.

Update for 11:15 p.m. ET: I want to emphasize that Jay’s sources did not tell him which companies are getting more or less money than other companies. They only named the three companies. The Wall Street Journal’s report suggests that Boeing and SpaceX will be getting more money than Sierra Nevada, but we don’t have any information about that angle of the story. NASA promises that all will be revealed in the morning, and of course we’ll pass that along.

NASA insists human space program still strong

NASA is on track with its goals for future space exploration, including the development of a new rocket and spacecraft designed to take astronauts to asteroids and Mars, the agency’s administrator told lawmakers Thursday.

NASA chief Charles Bolden testified before the Senate Subcommittee on Science and Space today to discuss NASA’s human spaceflight ambitions and its work to turn them into a reality.

“Contrary to popular belief, this has been an incredible year for NASA,” Bolden said.

He pointed to the completion of the International Space Station, the burgeoning commercial space sector that will assume the responsibility of taking cargo and eventually astronauts to the orbiting outpost, and the concurrent development within NASA of a new heavy-lift rocket and space capsule designed to explore farther out in the solar system, as indicators that NASA’s future is vibrant despite the tough economic times.



NASA

Bolden listed these three areas as the agency’s key priorities for the future. NASA retired its 30-year space shuttle program in July to focus instead on manned exploration beyond low-Earth orbit.

The transition left a gap in U.S. human spaceflight capabilities, and the agency is currently relying on Russian rockets to take astronauts to and from the space station until U.S. commercial services become available.

In the meantime, NASA is also moving ahead with the development of its Space Launch System and Orion Multi-Purpose Crew Vehicle. The booster and space capsule are being designed to carry astronauts on future missions to an asteroid and Mars. The design of the MPCV capsule is based on plans for NASA’s Orion spacecraft, which was originally part of the now-defunct Constellation program to return astronauts to the moon.

Bolden said incremental tests have already been completed for the $10 billion Space Launch System. Most recently, NASA successfully test-fired a huge upper-stage rocket engine, called the J-2X, on Nov. 9 at the Stennis Space Center in Mississippi.

The agency is aiming to complete an unmanned test flight of the MPCV capsule by 2014.

The NASA administrator also spoke about the challenges of working within such a difficult fiscal climate, particularly without the benefit of a clearly established budget. Like many other federal agencies, NASA has been forced to trim costs across a wide variety of programs.

“When I talk about prioritization, that is exactly what we’re doing,” Bolden said. “There are science imperatives that we have to be able to satisfy if we’re going to go to Mars. There’s no capability we can drop off the table. How do we accomplish the critical goals and objectives, but do it with less?”

Yet, Bolden expressed optimism that NASA is on track, with a manned mission to the Red Planet firmly in its sight.

“I think people are excited about space,” Bolden said. “We are putting in place a capabilities-driven program because we have decided that our ultimate destination for humans is Mars.”

And, in an indication that NASA is committed to its goals for human spaceflight, the agency recently started accepting applications for its next astronaut class.

“I don’t recruit astronauts if I don’t intend to fly them,” Bolden said.

J-2X Rocket: What’s Next in NASA Spaceflight

J-2X Test Firing, Credit: NASAJ-2X Test Firing, Credit: NASAFor those of you that think that the US manned space program is on its way out, I have news for you! NASA recently conducted a successful 499.97-second firing of its J-2X rocket engine, the successor to the J-2 and the J-2S, on November 9, 2011. This is just one thing of the many missions that NASA has planned for the future.

The 500-second (give or take a few hundreths of a second) test firing (see below for the video) marked another step in in the development of NASA’s heavy-lift Space Launch System (SLS) which is expected to replace the Space Shuttle following the cancellation of the over-budget and problematic Constellation Program.

The J-2X could be used as the second-stage engine for the SLS, which will be capable of carrying both unmanned and manned trips around the moon. It’s the same heavy launch vehicle that will carry the manned Multi-Purpose Crew Vehicle (MPCV) on deep-space missions that will last up to 21 days. According to NASA the SLS will be safe, affordable, and sustainable.

In addition to testing the J-2X, NASA plans to flight-test the Orion spacecraft–made by Lockheed Martin Space Systems–in 2014. Orion was originally a part of the now-cancelled Constellation Program, but NASA retooled its development to fit the SLS, and as part of the SLS it will fly on the J-2X. According to NASA, the 2014 flight will be unmanned, will fly two orbits high above the Earth, and it will make a water landing.

The J-2X itself is a rocket engine capable of 294,490 pounds-force (lbf) of thrust that uses liquid oxygen and liquid hydrogen fuel (LOX and LH2). The J-2X comes via Pratt Whitney Rockedyne, a rocket engine designer and manufacturer. The original J-2 motor was used on the Saturn V and the Saturn 1B rockets which are famous for the Apollo program and Skylab.

According to Mike Kynard, Space Launch System Engines Element Manager at NASA’s Marshall Space Flight Center in Huntsville, Alabama, the J-2X engine team and the SLS program are extremely happy that the test was safe and successful, and that “this engine test firing gives us critical data to move forward in the engine’s development.” In time, this rocket engine will carry man back into space on long deep space missions.

Funding for NASA program to replace shuttle comes up short

The allocation for the commercial crew program, which will team the space agency with private companies to develop a new vehicle for taking astronauts to the International Space Station, is part of a spending bill that will finance several federal agencies, including the National Aeronautics and Space Administration, in fiscal 2012.

The compromise legislation was brokered by House and Senate negotiators and is expected to pass later this week.

It would provide $17.8 billion for the space agency — $648 million below the fiscal 2011 level and $924 million less than President Barack Obama requested.

NASA could have fared worse. The original House proposal called for $1 billion less than what’s in the compromise.

The James Webb Space Telescope, the agency’s top science priority, would receive the $529 million it needs to proceed with a 2018 launch. House lawmakers had proposed giving the project nothing unless NASA identified programs to delay or eliminate in order to pay for the $8.8 billion telescope, which has been beset by cost overruns.

Other NASA-related provisions in the budget deal would provide:

— $1.2 billion for the Orion multi-purpose crew vehicle

— $1.86 billion for the Space Launch System, the heavy-lift rocket that will carry Orion on a planned Mars mission.

— $573 million related to retirement of the space shuttle.

— $2.8 billion for the space station.

Another provision would continue to bar NASA and the Office of Science and Technology Policy from engaging in bilateral activities with China unless authorized by Congress.

Sen. Bill Nelson, D-Florida, called the deal “good news” for the space program.

“This budget makes a major investment in the next generation of human space flight,” he said.

NASA officials have pushed Congress to provide full funding for the commercial crew program, which will help private companies design, build and launch spacecraft to and from the space station.

NASA originally was aiming for an initial launch in 2015, but administrators have suggested that could be pushed back to 2017 or later without adequate funding.

“At first glance, we are concerned about the funding level for commercial crew, which is significantly below the president’s request and could extend the length of our dependence on Russia to get to space,” NASA spokesman Michael Cabbage said Tuesday.

NASA has agreed to pay Russia for seats on its Soyuz rockets to get to the space station. The price per round trip is about $62 million, according to the agency.

Dale Ketcham, director of the Spaceport Research Technology Institute at the University of Central Florida, called it a “very disappointing decision to direct more money to Moscow.”

NASA has confidence in Russian colleagues

The future of NASA’s orbital laboratory may be on the line Sunday night, with a much-anticipated launch of a Russian rocket carrying three astronauts to the International Space Station.

That’s because it will be the first human launch since August, when a Russian rocket lifting a Progress spacecraft carrying supplies to the station blew up en route.

Both the unmanned Progress and crewed Soyuz vehicles use a similar launch system.

The Russians said a faulty component caused the failed launch, but the launch system itself had no fundamental flaw. Since the accident, two Progress vehicles have reached orbit without issue.

“We have complete confidence in our Russian colleagues,” said Mike Suffredini, manager of the International Space Station Program.

Flying aboard the Soyuz are NASA astronaut Dan Burbank and Russian cosmonauts Anton Shkaplerov and Anatoli Ivanishin.

They’ll relieve the station’s commander, Mike Fossum, as well as Satoshi Furukawa and Sergei Volkov, who have spent more than five months in orbit and are due to return to Earth on Nov. 21.

Like Suffredini, the space station astronauts have expressed confidence in the Russian rocket.

“With as many successful launches as they’ve had for many years, it’s clearly not a design problem,” Fossum said from orbit.

“It goes back to some kind of a process problem, they went all the way through that, they rebuilt the engine to make sure there were no lingering concerns, and I think these launches are going to be some of the highest probability-of-success launches ever.”

After the August accident, the station dropped from six to three crew members. The arrival of Burbank’s crew is essential to ensuring continuous human occupation of the football field-sized facility.

Suffredini said the station can be operated remotely for a significant period of time without crew members, as long as no significant problems develop onboard.

Nevertheless, he said he’s eager to begin resuming flights to the space station, and to prove the reliability of the Russian rocket, currently the only launch option. NASA retired its space shuttle program in July.

If Sunday’s launch, set for 10:14 p.m., occurs as expected, NASA and the Russians will launch another crew in late December to fully staff the space station with six astronauts.

A full staff will allow astronauts to properly operate the space station and conduct a full docket of science experiments, some of which have been put on hold with only three crew members.

“As soon as I get on station, I’ll be rolling up my sleeves and jumping into the lab and starting to do a number of these scientific experiments,” said Don Pettitt, who’s scheduled to fly to the laboratory in December.

Watch NASA test-fire its brand new J-2X rocket engine

NASA’s new Space Launch System isn’t going anywhere without some monstrous engines. The second stage engine will be the J-2X, a descendant of the Apollo-era J-2, and NASA just lit one off for 500 seconds in a very loud, steam-filled test.

The J-2 rocket engine was developed back in 1960 by Boeing, and a cluster of five of them powered the second stage of the Saturn V moon rocket. Figuring that it’s a good idea to just go with what works, NASA has decided to re-enlist the J-2 in the form of the J-2X to power the second stage of the SLS. The J-2X is an upgrade from the original J-2, offering simpler and more efficient operation while also being cheaper and easier to build. It’s also more powerful, producing nearly 300,000 pounds of thrust, which is a whole heck of a lot, as you can see from the vid below.

Of course, the J-2X is only powering the second stage of the SLS. The first stage will be driven by five (!) RS-25D/Es, which are the same engines that powered the space shuttle. Oh, and with a couple solid rocket boosters thrown in for good measure. The SLS isn’t scheduled to launch for at least five years, but when it goes up, it’s going to be one of the most epic rocket launches the world has ever seen.

NASA hopes to resume flights to space station Sunday

The future of NASA’s orbital laboratory may be on the line Sunday night, with a much-anticipated launch of a Russian rocket carrying three astronauts to the International Space Station.
