NASA Study Grades Climate Models, Finds Higher Temperatures Likely

Posted on by

NASA today announced the results of a new study by the National Center for Atmospheric Research. It shows that climate model projections that predict a greater rise in global temperature are more likely to be accurate than those predicting a lesser rise. NASA stated that the findings could provide a breakthrough in predicting the range of global warming expected in the future. The study was published this week in the journal Science.

The study looked at 16 leading climate models and observed how well each reproduces observed relative humidity in Earths tropic and subtropic regions. They compared the models with data from NASA satellite instruments called the Atmospheric Infrared Sounder (AIRS) and the Clouds an Earths Radiant Energy System (CERES), as well as a NASA data analysis named the Modern-Era Retrospective Analysis for Research and Applications (MERRA). The studys findings show that the climate models that more accurately show observed relative humidity also show the greatest amounts of warming as a result of greenhouse gasses in the atmosphere.

There is a striking relationship between how well climate models simulate relative humidity in key areas and how much warming they show in response to increasing carbon dioxide, said John Fasullo, research scientist at the National Center for Atmospheric Research. Given how fundamental these processes are to clouds and the overall global climate, our findings indicate that warming is likely to be on the high side of current projections.

The study focused on dry subtropics, NASA stated, because seasonal drying and the associated decrease in clouds are similar to patterns projected by climate models. If we can better represent these regions in models, we can improve our predictions and provide society with a better sense of the impacts to expect in a warming world, said Fasullo.

NASA stated that because established physical laws that guide the atmosphere are difficult to translate into software, each climate model differ slightly in its predictions. In particular, those associated with clouds are too small because satellite failure, observational errors, and other inconsistencies make a consistent global cloud census difficult. Satellites such as the AIRS, though, are more reliable at measuring water vapor and estimating the global distribution of relative humidity.

These results were hiding in plain sight, said AIRS Eric Fetzer, an AIRS project scientist who was not involved in the study. We have known for 30 years that clouds complicate climate forecasts, but instead of looking directly at clouds, this study examines clear regions. Their conclusions indicate that better model physics for clear areas will lead to improved climate forecasts, but warming is likely to be at the high end of current forecasts.

redOrbit Staff & Wire Reports Your Universe Online

Officials at NASAs Goddard Space Flight Center marked National Disability Month by welcoming 16 ninth- through twelfth-grade students from the Maryland School for the Blind on October 25.

Sixteen pupils visited the Greenbelt, Maryland-based facility, where they received a hands-on and audible learning experience about what happens at NASA and career opportunities available to them, NASA officials said in a statement.

The main purpose of the visit was to inform the students about science, technology, engineering and mathematics, or STEM, careers [sic] opportunities available at NASA for blind and visually impaired individuals, they explained. The agenda included a tour of the Spacecraft Fabrication Facility, including Machining Technology, Composites, Rapid Prototyping, and the Model Shop.

The students were allowed to tour the space blanket laboratory, where they learned about the blankets that are used to protect satellites from harsh temperatures while in space, and where they were allowed to feel the texture of the items used to cover probes such as the Hubble Space Telescope.

The blanketing material used on the [Hubble] telescope was made up of 16 layers of dimpled aluminum with an outer Teflon skin, NASA said. The multi-layer insulation or blanket protects satellite instruments from the severe and rapid temperature changes they experience as they move in orbit from very hot sun to very cold night, even though the blanket is incredibly thin, measuring less than one-tenth of an inch thick when laid flat.

They took part in a hands-on presentation about ice cores from Goddard Education Specialist Katherine Bender, who also discussed internship opportunities at the Space Flight Center. The students also toured the facilitys Machining Technology, Composites, Rapid Prototyping, and the Model Shop during the tour, which was coordinated by Kenneth A. Silberman and Katherine Bender of NASA Goddards Education Office.

Silberman and Bender worked with Colleen Shovestull, a special educator and science teacher at the Maryland School for the Blind to make the visit happen, NASA said. The partnership is being formed by the NASA Goddard Education Office, the Equal Opportunity Programs Office (EEOPO), and the Equal Accessibility Advisory Committee (EAAC). The visit stems from a partnership that the Individuals with Disabilities Advisory Group is establishing with the Maryland School for the Blind.

Report: NASA Set to Announce Ambitious Moon Base Plan

Posted on by

With President Barack Obama back in the White House for a second term, NASA is reportedly getting ready to reveal plans to send astronauts back to the moon and possibly even to build an orbiting base around Earth's satellite.

It's been speculated for some time that the space agency has been mulling the construction of a floating Moon base that would serve as a launching site for manned missions to Mars and other destinations more distant than any humans have traveled to so far.

Those plans may have already been greenlighted by the Obama administration, Space.com reported Friday. NASA was reportedly waiting to announce such an ambitious endeavor until it was determined whether Obama or his challenger, Mitt Romney, was going to be president.

The Orlando Sentinel reported several months ago that the proposed outpost, called a "gateway spacecraft," would support "a small astronaut crew and function as a staging area for future missions to the moon and Mars."

The proposed space station would be situated at what's called a Lagrangian point, or L-Point, a place where the gravitational pull of two large bodiesin this case the Earth and the Moonare at an equilibrium, making it possible to place a spacecraft in a fixed spot in space at relatively little expense. NASA wants to put its base at Earth-Moon L-Point 2, on the far side of the Moon, according to reports from several news sites.

That would place the spacecraft about 277,000 miles from Earth and about 38,000 miles from the Moon's surface. Though taking advantage of an L-point reduces the power cost of fixing an object in space, the project's costs "would certainly run into the billions of dollars," according to the Sentinel.

Using such a base as a launching station for manned trips to Mars or to a near-Earth asteroid probably wouldn't happen until the 2020s.

The newspaper cited documents it obtained pertaining to a White House briefing on the idea given by NASA administrator Charles Bolden earlier in September. The Sentinel noted at the time that it was "unclear" whether the Obama administration supported the project.

Now Space.com says space policy expert John Logsdon of George Washington University believes the moon base project has "probably already been cleared with the Obama Administration."

"NASA has been evolving its thinking, and its latest charts have inserted a new element of cislunar/lunar gateway/Earth-moon L2 sort of stuff into the plan. They've been holding off announcing that until after the election," Logsdon told the site, noting that Romney "had pledged to reassess and possibly revise NASA's missions and direction."

NASA Testing Interplanetary Internet System

Posted on by

The Internet has become an integral part of people's lives around the globe, but could the Web exist in space? Researchers at NASA, not content to remain fixed to an Earth-bound system, are pushing the boundaries of network communications by testing what could one day amount to an interplanetary Internet.

Working in tandem with the European Space Agency (ESA), NASA has used its Disruption Tolerant Networking (DTN) program to test network operations that replicate some of the functions of the Internet, such as sending messages across long distances. In addition to messaging, last month astronaut Sunita Williams used the DTN system to control a tiny LEGO robot situated in a lab back on Earth from a special NASA-developed laptop on the International Space Station. The experiment was designed to simulate a scenario in which an astronaut located in an orbiting spacecraft might remotely control a robotic rover on the surface of a planet.

"The demonstration showed the feasibility of using a new communications infrastructure to send commands to a surface robot from an orbiting spacecraft and receive images and data back from the robot," NASA's Badri Younes said in a statement on the space agency's site.

"The experimental DTN we've tested from the space station may one day be used by humans on a spacecraft in orbit around Mars to operate robots on the surface, or from Earth using orbiting satellites as relay stations," Younes said.

According to NASA, the DTN system uses a system similar to Internet Protocol called a "Bundle Protocol," an analog architecture that makes the idea of constructing an interplanetary Internet easier to envision. Eventually, the DTN system could become a primary means of communicating with deep space missions as well as a way to control unmanned missions from long distances.

WASHINGTON, Nov. 9 (UPI) -- NASA and the European Space Agency say they have tested an "interplanetary" communication network replicating some of the functions of the Internet.

As part of the experiment, the crew of the International Space Station Expedition used a NASA-developed laptop to operate a small LEGO robot at the European Space Operations Center in Darmstadt, Germany.

"The demonstration showed the feasibility of using a new communications infrastructure to send commands to a surface robot from an orbiting spacecraft and receive images and data back from the robot," said Badri Younes, deputy associate administrator for space communications and navigation at NASA Headquarters in Washington.

The experiment was a test of a Disruption Tolerant Networking protocol that allows standardized communications similar to the Internet technology.

Unlike the TCP/IP protocol used for worldwide Internet connections, DTN was designed to deal with disconnections, errors and delays of signal that would be experienced during interplanetary communication, NASA said in a release Friday.

"In DTN, data move through the network 'hop-by-hop.' While waiting for the next link to become connected, bundles are temporarily stored and then forwarded to the next node when the link becomes available," NASA said.

Eventually the DTN system could eventually become the prime method of communicating with deep space missions as well as a way to control unmanned missions from long distances, the space agency said.

NASA Plans for 3-D Printing Rocket Engine Parts Could Boost Larger Manufacturing Trend [Video]

Posted on by

There is a lot riding on NASA's Space Launch System (SLS). Not only does the agency's first new heavy-lift booster since the Saturn 5 that took U.S. astronauts to the moon play a central role in the future of the American spaceflight, it also provides a critical test for technology expected to figure prominently in revamping the country's ailing manufacturing industry.

NASA's Marshall Space Flight Center in Huntsville, Ala., is testing an approach called selective laser melting (SLM) to create parts for the J-2X and RS-25 rocket engines that will power the SLS, whose maiden voyage is slated for 2017 (pdf). The space agency expects SLM to simplify the process of making certain parts and in some cases halve the cost of producing thema huge advantage for NASA, provided the components can withstand the rigors of lifting the largest launch vehicle ever built into space.

The first version of the SLS is a 70-metric-ton rocket that will lift around 70,000 kilograms while providing 10 percent more thrust than the Saturn 5. This SLS will power the 2017 Exploration Mission 1, which will launch an unmanned Orion spacecraft on a circumlunar voyage as a precursor to Exploration Mission 2. That mission, scheduled for 2021, will use a 130-metric-ton version of the SLS to launch Orion and a crew of up to four astronauts. This second SLS will be capable of lifting more than 130,000 kilograms and provide 20 percent more thrust than the Saturn 5.

Cash-strapped NASA is counting on SLM to speed SLS's development and reduce the program's costs. SLM is a type of additive manufacturing technology, which uses computer-aided design (CAD) files to build parts layer by layer (3-D printing is perhaps the most well known example of additive manufacturing). With SLM, a finely powdered alloy is deposited in a layer as thin as 20 microns and then fused together by a focused laser beam inside a chamber containing inert gas such as argon or nitrogen. Once the laser has turned that layer into solid metal, another layer of powder is deposited and the process is repeated.

NASA is testing the viability of making engine parts from nickel-based alloys using an SLM machine (pdf) with a square cubical build chamber measuring 250 millimeters on each side and a depth of 280 millimeters. These same alloys are already used to make 90 percent of the parts in the RS-25 and J-2X engines. The key difference is that the engines' current elements are forged and then milled into their final shapes. Often several pieces must be welded together to create a part.

Marshall engineers began evaluating alternative approaches to building parts for the next-generation J-2X engine a few years ago. In late 2010 they turned to SLM to create a duct for a gas generator in the engine. "The part itself is not necessarily complexit's a [10-centimeter] in diameter duct that's bent in a U-shape," says Andy Hardin, SLS Liquid Engines Office engine integration hardware lead. However, "because of the thickness and the radius of the bend, it's very difficult to make. We were having trouble getting vendors to do this properly."

After printing the duct, the engineers set about deconstructing it to study its metallurgy and microscopic structure. They found that although the part was not as strong as a forged and milled duct, it fell within the "minimal acceptable range," Hardin says. "If you made a part [using SLM], the material properties would be degraded somewhat but not much." One structural advantage is that the part required no welding. "When you make a part out of multiple pieces, welds are always the weakest points," he adds. This opened the door for the engineers to consider using SLM to make other engine parts as well.

SLM, and additive manufacturing in general, is not a viable option for all J-2X or RS-25 engine parts. For starters, the printed parts must be small enough to fit in the machine's build chamber. And a lot more testing is required to determine whether components such as turbines, which operate under the most intense conditions, could be made properly using SLM, Hardin says. Good candidates for SLM are those with complex geometries that are difficult to make and require multiple welds to achieve those geometries. Depending on how well printed J-2X parts fare in tests, Marshall engineers hope to at some point use SLM to likewise make parts for the older RS-25, which served as the space shuttle's main engine throughout its 30-year history.

Another incentive for NASA to transition to additive-manufactured parts: their contractors are beginning to adopt the technology in their factories. "As a big customer for many of these manufacturers, we thought it was important that we understand the technology," Hardin says. NASA does not want to hold manufacturers back by failing to create specifications for parts made using SLM or some other additive process, he adds.

As such, NASA's success with SLM could be a boon to a flagging U.S. manufacturing industry that seeks to create more domestic jobs but has been reluctant do so because of high costs.
