NASA preparing to send a 3D printer into space

MOFFETT FIELD, Calif. NASA is preparing to launch a 3-D printer into space next year, a toaster-sized game changer that greatly reduces the need for astronauts to load up with every tool, spare part or supply they might ever need.

The printers would serve as a flying factory of infinite designs, creating objects by extruding layer upon layer of plastic from long strands coiled around large spools. Doctors use them to make replacement joints and artists use them to build exquisite jewelry.

In NASA labs, engineers are 3-D printing small satellites that could shoot out of the Space Station and transmit data to earth, as well as replacement parts and rocket pieces that can survive extreme temperatures.

Any time we realize we can 3-D print something in space, its like Christmas, said inventor Andrew Filo, who is consulting with NASA on the project. You can get rid of concepts like rationing, scarce or irreplaceable.

The spools of plastic could eventually replace racks of extra instruments and hardware, although the upcoming mission is just a demonstration printing job.

If you want to be adaptable, you have to be able to design and manufacture on the fly, and thats where 3-D printing in space comes in, said Dave Korsmeyer, director of engineering at NASAs Ames Research Center at Moffett Field, about 35 miles south of San Francisco.

For the first 3-D printer in space test slated for fall 2014, NASA had more than a dozen machines to choose from, ranging from $300 desktop models to $500,000 warehouse builders.

All of them, however, were built for use on Earth, and space travel presented challenges, from the loads and vibrations of launch to the stresses of working in orbit, including microgravity, differing air pressures, limited power and variable temperatures.

As a result, NASA hired Silicon Valley startup Made In Space to build something entirely new.

Imagine an astronaut needing to make a life-or-death repair on the International Space Station, said Aaron Kemmer, CEO of Made in Space. Rather than hoping that the necessary parts and tools are on the station already, what if the parts could be 3-D printed when they needed them?

NASA's Cassini Spacecraft Finds Ingredient of Household Plastic in Space

NASA's Cassini spacecraft has detected propylene, a chemical used to make food-storage containers, car bumpers and other consumer products, on Saturn's moon Titan.

This is the first definitive detection of the plastic ingredient on any moon or planet, other than Earth.

A small amount of propylene was identified in Titan's lower atmosphere by Cassini's Composite Infrared Spectrometer (CIRS). This instrument measures the infrared light, or heat radiation, emitted from Saturn and its moons in much the same way our hands feel the warmth of a fire.

Propylene is the first molecule to be discovered on Titan using CIRS. By isolating the same signal at various altitudes within the lower atmosphere, researchers identified the chemical with a high degree of confidence. Details are presented in a paper in the Sept. 30 edition of the Astrophysical Journal Letters.

"This chemical is all around us in everyday life, strung together in long chains to form a plastic called polypropylene," said Conor Nixon, a planetary scientist at NASA's Goddard Space Flight Center in Greenbelt, Md., and lead author of the paper. "That plastic container at the grocery store with the recycling code 5 on the bottom -- that's polypropylene."

CIRS can identify a particular gas glowing in the lower layers of the atmosphere from its unique thermal fingerprint. The challenge is to isolate this one signature from the signals of all other gases around it.

The detection of the chemical fills in a mysterious gap in Titan observations that dates back to NASA's Voyager 1 spacecraft and the first-ever close flyby of this moon in 1980.

Voyager identified many of the gases in Titan's hazy brownish atmosphere as hydrocarbons, the chemicals that primarily make up petroleum and other fossil fuels on Earth.

On Titan, hydrocarbons form after sunlight breaks apart methane, the second-most plentiful gas in that atmosphere. The newly freed fragments can link up to form chains with two, three or more carbons. The family of chemicals with two carbons includes the flammable gas ethane. Propane, a common fuel for portable stoves, belongs to the three-carbon family.

Voyager detected all members of the one- and two-carbon families in Titan's atmosphere. From the three-carbon family, the spacecraft found propane, the heaviest member, and propyne, one of the lightest members. But the middle chemicals, one of which is propylene, were missing.

NASA May Slam Captured Asteroid Into Moon (Eventually)

Decades from now, people on Earth may be gearing up for an unprecedented celestial spectacle the intentional smashing of an asteroid into the moon.

NASA is currently planning out an ambitious mission to snag a near-Earth asteroid and park it in a stable orbit around the moon, where it could be visited repeatedly by astronauts for scientific and exploration purposes. But the asteroid-capture mission may not end when astronauts leave the space rock for the last time. Seeing it through could require disposing of the asteroid in a safe and possibly very dramatic manner, experts say.

"You can be comfortable that [the asteroid] will stay in this orbit for 100 years or so," Paul Chodas, a scientist with the Near-Earth Object Program Office at NASA's Jet Propulsion Laboratory in Pasadena,Calif., said earlier this month during a panel discussion at the American Institute of Aeronautics and Astronautics' Space 2013 conference in San Diego.[NASA's Asteroid-Capture Mission in Pictures]

"But if that's not enough, I think that, once you're finished with it and you have no further need of it, send it in to impact the moon," Chodas added. "That makes sense to me."

A bold plan

NASA announced the asteroid-retrieval effort in April. The plan calls for a robotic spacecraft to rendezvous with a roughly 25-foot-wide (7.6 meters), 500-ton space rock and drag it to a stable lunar orbit.

Alternatively, the probe could break a chunk off a larger asteroid; NASA is investigating both options. Either way, astronauts would then fly out to this transplanted rock using NASA's Orion capsule and Space Launch System mega-rocket (SLS), which are slated to fly crews together for the first time in 2021.

The mission represents one way to achieve a major goal laid out by President Barack Obama, who in 2010 directed the space agency to get astronauts to a near-Earth asteroid by 2025, then on to the vicinity of Mars by the mid-2030s.

Grabbing a space rock would also help develop asteroid-mining technology, reveal insights about the solar system's early days and give humanity critical experience working in deep space, NASA officials say.

"It provides a tremendous target to develop our capabilities and operation techniques for our crews in the future as we go beyond low-Earth orbit," NASA human exploration chief Bill Gerstenmaier said during the panel discussion at Space 2013.

NASA 3D printer: The next revolution in space?

NASA 3D printer could be used to make tools and spare parts for the International Space Station by next year, instead of shipping them up from Earth. NASA is working with Made in Space to produce a 3D printer.

A California-based company that will launch a 3D printer to the International Space Station in 2014 is aiming to change the way space agencies think about how they transport goods to the orbiting outpost. But, using a machine to spit out spare parts for the space station is only the beginning.

Built by the firm Made in Space, Inc., the first 3D printer in space will launch to the space station aboard commercial spaceflight provider SpaceX's Dragon capsule. The mission will largely be a proof-of-concept flight, in which astronauts will use the device to demonstrate its functionality in the microgravity environment, Mike Chen, Made in Space co-founder and chief strategy officer, told an audience at World Maker Faire in Queens here on Sept. 21.

While astronauts will initially use the 3D printer to create spare parts and tools for the space station. Made in Space is hoping "makers" on Earth will get a chance to flex their creativity by coming up with designs for science experiments, innovative projects and artwork.

"Once our printer is there, we're going to be opening it up to the world to print things in space," Chen said, while openly soliciting ideas and encouraging people to contact the company with thoughts.

If all goes well, a permanent version of the 3D printer will be launched to the International Space Station in 2015.

"The paradigm shift that we want everyone to understand is: instead of launching things to space, just print it there," Chen said. "Why would you go through all the energy to build it here and launch it, when you can just build it there?"

Made in Space was founded in 2010 with the mission of broadening access to space. "[I]t's really expensive and difficult to launch things into space, and that puts a real dampening effect on innovation," Chen said.

NASA's new commercial supply ship reaches space station

CAPE CANAVERAL, Fla. NASA's newest delivery service pulled up at the International Space Station on Sunday after a week's delay, bringing more than a half-ton of meals and special treats to the astronauts who assisted in the high-flying feat.

With the smooth linkup, Orbital Sciences Corp. became only the second company to accomplish such a far-flung shipment.

The space station astronauts used their ship's huge robot arm to grab the Cygnus capsule, as the two vessels zoomed 260 miles above the Indian Ocean.

"Everybody is just so excited," Mission Control radioed. Ground teams described the achievement as "epic" and "superb."`

Orbital Sciences launched the Cygnus capsule on this test flight from Virginia on Sept. 18. It was supposed to reach the space station last Sunday, but got held up by inaccurate navigation data. A software patch fixed everything. Then the Cygnus had to wait for a Russian spacecraft bringing three new astronauts in midweek.

The successful arrival means the Virginia-based company can begin making good on a $1.9 billion contract with NASA for a series of Cygnus deliveries. The next one could fly by Christmas.

Applause could be heard in Mission Control once Italian astronaut Luca Parmitano grabbed hold of Cygnus with the space station's hulking mechanical arm.

"Good capture. That's a long time coming," Mission Control radioed.

"Smiles all around," added Orbital Sciences in a tweet.

Sunday's successful operation culminated years of effort for Orbital Sciences, which was hired by NASA along with the California-based Space Exploration Technologies Corp. to keep the space station well stocked in this post-shuttle era.

NASA satellite images confirm creation of new island in Pakistan

4:32pm, Sat 28 Sep 2013 Second earthquake hits Pakistan - last updated Sat 28 Sep 2013

NASA has confirmed that a recent earthquake in Pakistan created a new island about a kilometre off its Gwadar coastline in the Arabian Sea.

The powerful earthquake struck Pakistan's south-west Baluchistan province on 24 September, killing more than 500 people and leaving thousands homeless.

Two days later, NASA's earth-observing satellite flew over the area and confirmed that a new island had indeed appeared.

The image below shows the part of the coastline before the earthquake. Lighter patches in the water suggest either a shallow seabed or suspended sediment, NASA said.

The image below was taken after the earthquake and clearly shows the new island jutting out above the waves.

Experts say the island was most likely created by a "mud volcano" - a jet of mud, sand and water - which caused the seabed to rise.

Another image, released by Pakistan's National Institute of Oceanography, shows the surface of the island in greater detail.

It is estimated to stretch 75 to 90 metres (250 to 300 feet) across and stands 15 to 20 metres (60 to 70 feet) above the water.
