On his “smart” watch, David Miranda checks e-mail and appointments, dictates text messages and performs Google searches, among other tasks.

The accessory makes the Kennedy Space Center engineer an early adopter of “wearable technology” that one leading consumer electronics company predicts will emerge as a hot workplace trend this year .

But in “wearables” like the LG watch or Google Glass eye wear, Miranda and a group of colleagues see the potential for something more visionary: helping KSC workers do their jobs more safely and efficiently, and maybe someday also astronaut explorers.

“Whether they’re walking on the Martian surface or on an asteroid, this could give them a lot of critical information to help them be successful,” said Miranda, 31, of Orlando.

Miranda leads an eight-person team of young engineers who this month are beginning a two-year project to develop a prototype headset that works something like a Google Glass for space operations.

X-Rays: Next-Gen Way to Travel and Talk in Space?

Galaxies

NASA scientists say they have figured out a way to use X-rays to both communicate with long-distance spacecraft, as well as navigate as they sail past the outer limits of the solar system.

They say that using X-rays is faster than existing radio wave communications, can carry more information and won’t be blocked when spacecraft enter a planet’s thick atmosphere.

“While we are using X-ray navigation to guide us to Pluto, we might also use X-ray communication to talk back to Earth,” said Keith Gendreau, principal investigator at NASA’s Goddard Space Flight Center in Greenbelt, Md.

NASA Completes Successful Battery of Tests on Composite Cryotank

NASA has completed a complex series of tests on one of the largest composite cryogenic fuel tanks ever manufactured, bringing the aerospace industry much closer to designing, building, and flying lightweight, composite tanks on rockets.

“This is one of NASA’s major technology accomplishments for 2014,” said Michael Gazarik, NASA’s associate administrator for Space Technology. “This is the type of technology that can improve competitiveness for the entire U.S. launch industry, not to mention other industries that want to replace heavy metal components with lightweight composites. These tests, and others we have conducted this year on landing technologies for Mars vehicles, show how technology development is the key to driving exploration.”

The demanding series of tests on the 18-foot (5.5-meter) diameter tank were conducted inside a test stand at NASA’s Marshall Space Flight Center in Huntsville, Alabama. Engineers added structural loads to the tank to replicate the physical stresses launch vehicles experience during flight.

NASA representatives participated in a media teleconference this morning to discuss the June 28, 2014 near-space test flight of the agency’s Low-Density Supersonic Decelerator (LDSD), which occurred off the coast of the U.S. Navy’s Pacific Missile Range Facility in Kauai, Hawaii.

A high-altitude balloon launch occurred at 8:45 a.m. HST (11:45 a.m. PDT/2:45 p.m. EDT) from the Hawaiian island facility. At 11:05 a.m. HST (2:05 p.m. PDT/5:05 p.m. EDT), the LDSD test vehicle dropped away from the balloon as planned and began powered flight. The balloon and test vehicle were about 120,000 feet over the Pacific Ocean at the time of the drop. The vehicle splashed down in the ocean at approximately 11:35 a.m. HST (2:35 p.m. PDT/5:35 p.m. EDT), after the engineering test flight concluded. The test vehicle hardware, black box data recorder and parachute were all recovered later in the day.

“We are thrilled about yesterday’s test,” said Mark Adler, project manager for LDSD at NASA’s Jet Propulsion Laboratory in Pasadena, California. “The test vehicle worked beautifully, and we met all of our flight objectives. We have recovered all the vehicle hardware and data recorders and will be able to apply all of the lessons learned from this information to our future flights.”

International Space Station Being Used As A Technology Test Bed

The International Space Station is critically important to NASA’s future exploration missions. The orbiting outpost provides a platform to test technologies in a long-duration weightless environment; conditions which are impractical to replicate on Earth. NASA’s Space Technology Mission Directorate is utilizing the space station as a test bed for multiple game-changing technology demonstrations.

“The International Space Station is our national laboratory for foundational space technology development,” said Dr. Michael Gazarik, Associate Administrator for the Space Technology Mission Directorate. “The new technologies we fly and test on the station will help create the new capabilities needed for our Asteroid Initiative and our Evolvable Mars Campaign. The International Space Station is an innovation incubator for the advanced space technology that will get us to Mars, and beyond.”

Robots Will Pave the Way to Mars

The first robot capable of building anything including a replica of itself, might cost a fortune to develop; the billionth copy would be as cheap as dirt. Send some of them into space and they could build new armies out of planetary rubble and dust, then go on to construct enough spaceships and refueling stations to carry the human race to other planets and, eventually, other stars.

That’s the scenario laid out some 35 years ago by a team of academics and NASA engineers meeting at the University of Santa Clara, in California. They envisioned robotic factories that would cover the moon and exploit the asteroid belt, extracting the resources needed to build more and better versions of themselves and also vast orbiting telescopes, space colonies, and other structures too big to launch from Earth. Over time, the researchers wrote, these bots could “produce an ever-widening habitat for man throughout the Solar System” and beyond it. The approach could become so successful, they warned, that we might have to worry about robotic population control.

NASA Langley part of new space tech research

April 17, 2014 | By Tamara Dietrich, tdietrich@dailypress.com

 

The technologies needed to get humans deeper into space and safely on another planet are continuing apace, and will take financial commitments for years to come, a NASA official says.

But NASA’s partnerships with industry and academia to develop and hone those technologies will also reap benefits on this planet, as well, he said.

“A deep-space exploration mission is, in some ways, imminent,” Michael Gazarik said Wednesday in a conference call with reporters to give updates on developing technologies and upcoming missions that will eventually enable manned exploration — to an asteroid, Mars or the moon of another planet.

Gazarik is the associate administrator for space technology at NASA headquarters. The broad umbrella of his Space Technology Mission Directorate includes the Game Changing Development Office at NASA Langley Research Center in Hampton, headed up by Steve Gaddis.

Gaddis helped spotlight some of those game-changing technologies Tuesday when Sen. Tim Kaine visited the center for an informational tour. There, Kaine said he was committed to NASA’s proposed $17.5 billion budget for fiscal year 2015, and even to see it increased in future. Read more (+)

A Step Up for NASA’s Robonaut: Ready for Climbing Legs

IM_R2_iss-shake-140424a

Getting your “space legs” in Earth orbit has taken on new meaning for NASA’s pioneering Robonaut program.

Thanks to a successful launch of the SpaceX-3 flight of the Falcon 9/Dragon capsule on Friday, April 18, the lower limbs for Robonaut 2 (R2) are aboard the International Space Station (ISS). Safely tucked inside the Dragon resupply vehicle, R2’s legs are to be attached by a station crew member to Robonaut’s torso already on the orbiting outpost.

R2’s upper body arrived on the space station back in February 2011 during the last flight of the space shuttle Discovery. That event signaled the first human-like robot to arrive in space to become a permanent resident of the laboratory.

Jointly developed by NASA’s Human Exploration and Operations and Space Technology mission directorates in cooperation with with General Motors, R2 showcases how a robotic assistant can work alongside humans, whether tasks are done in space or on Earth in a manufacturing facility.

NASA’s space station Robonaut finally getting legs

By MARCIA DUNN, AP Aerospace Writer | April 19, 2014

robotLEGS2

CAPE CANAVERAL, Fla. (AP) — Robonaut, the first out-of-this-world humanoid, is finally getting its space legs.

For three years, Robonaut has had to manage from the waist up. This new pair of legs means the experimental robot — now stuck on a pedestal — is going mobile at the International Space Station.

“Legs are going to really kind of open up the robot’s horizons,” said Robert Ambrose from NASA’s Johnson Space Center in Houston.

It’s the next big step in NASA’s quest to develop robotic helpers for astronauts. With legs, the 8-foot Robonaut will be able to climb throughout the 260-mile-high outpost, performing mundane cleaning chores and fetching things for the human crew.

The robot’s gangly, contortionist-bending legs are packed aboard a SpaceX supply ship that launched Friday, more than a month late. It was the private company’s fourth shipment to the space station for NASA and is due to arrive Easter Sunday morning.

One NASA astronaut launching to the International Space Station in May is ready to 3D print in space.

Astronaut Reid Wiseman, bound for the station in May, is eager to use the first 3D printer in space this summer. Wiseman, flying into space for the first time as a member of the Expedition 40/41 crew, thinks that the implications for 3D printing in space are exciting and far-reaching.

“Imagine if Apollo 13 had a 3D printer,” Wiseman said in a news conference this month. “Imagine if you’re going to Mars and instead of packing along 20,000 spare parts, you pack along a few kilograms of ink. Now, you don’t even need to know what part is going to break, you can just print out that part. Let’s say your screwdriver strips out halfway to Mars and you need a screwdriver, print out a screwdriver. Really, I think for the future, that’s pretty fascinating. I really like that and it’ll be fun to play with that on orbit.” Read more (+).

Collaboration Key to Successful Technology “Push”

Bill Farr

The Lunar Laser Communications Demonstration (LLCD) mission made history in October 2013 when it succeeded in transferring data at 622 Megabits per second, a rate six times that of comparable radio frequency systems, like going from dial up to a high-speed Internet connection. But this technological achievement in laser communications was at risk had it not been for the “push” researchers experienced when an important component, a photodiode detector, failed to perform as necessary during testing.

In the world of emerging technologies, a “push” is any activity attempting to expand on advancements to current challenges or limitations. Within NASA’s Space Technology Mission Directorate (STMD), projects like Deep Space Optical Communications (DSOC) seek to do just that. When LLCD was faced with the detector failure, a potential replacement was identified—one with a challenge: it was still under development with DSOC.

The LLCD experiment, now well known for its achievement, launched onboard the Lunar Atmosphere and Dust Environment Explorer (LADEE) from NASA’s Wallops Flight Facility in Virginia on September 6, 2013. A series of LLCD experiments began in late September with the first successful downlink from LADEE on September 28, just before LADEE reached lunar orbit. LLCD mission operations began in mid-October, and by October 21 six links were successfully completed.

Getting to that successful point, however, was not a straightforward path and required numerous collaborative efforts among individuals and organizations across NASA and industry.

Early in the mission life cycle, it became evident that there was a high probability of limited or no communications link opportunities for the LADEE launch due to clouds or inclement weather during the monsoon season at the optical ground station at White Sands Center in New Mexico. NASA’s Space Communications and Navigation (SCaN) Office stepped in by funding a back-up ground station at the NASA/Jet Propulsion Laboratory (JPL) Optical Communications Telescope Laboratory. The JPL back-up ground station project is referred to as LLOT, or the Lunar Lasercom OCTL Terminal. The JPL ground station has a telescope specifically designed for space optical communications experiments. The back-up station project required a demonstration only at the lowest downlink rate of 39 Mb/s. During early testing of that capability, the baselined commercial intensified photodiode detector failed to adequately detect data at 39 Mb/s.

The need to overcome this limitation was clear; fortunately the answer was already in the works.

Back in the summer of 2011, under SCaN funding, Bill Farr and Jeff Stern of JPL had begun WSi detector development in collaboration with the National Institute of Standards and Technology, building on what Farr described as NIST’s “ground-breaking achievements.”

“This naturally flowed into STMD’s Game Changing Development DSOC project starting in the fall of 2011,” said Farr. “Our DSOC project goal has been to make large arrays of WSi detectors to go behind 5- to 12-m diameter telescopes. We are presently fabricating 64-pixel arrays. At an interim step we fabricated the 8- and 12-pixel devices, which were suitable for use behind a 1-m telescope, such as at the JPL ground station.”

Farr and Stern fabricated and began testing their first WSi devices at the start of March 2012.

“In collaboration with NIST, by the end of April 2012 we had a record setting 93-percent system detection efficiency with single-pixel devices, and under the DARPA-funded InPho program performed a record setting 13-bits per photon demonstration using pulse-position-modulation (the preferred deep-space optical communications modulation format) with one of these devices,” Farr said of the testing results.

In September 2012, after the critical nature of issues with the commercial photodiode detector was deemed insurmountable, the challenge was firmly set. The LLOT project found that to succeed, it would be necessary to switch to the WSi detector and moving forward was review-board approved.

With that approval, the push was now truly on.

Farr’s own words best describe the dynamic collaborative efforts:

“I knew a local vendor, Photon Spot, Inc., (Monrovia, Ca.) starting a business in superconducting nanowire detectors. The LLOT project worked with Photon Spot to quickly assemble and lease a cryostat that would achieve the required 1-K operating temperature for the WSi detectors.

“The cryostat was delivered to JPL in April 2013. Matt Shaw and Kevin Birnbaum at JPL then led the effort under the LLOT project to get the detector array installed into this cryostat and then interfaced to the data acquisition system, which was originally selected to operate with the photodiode detector. Kevin came up with a novel interface using only off-the-shelf electronic modules in order to meet the tight project schedule and budget.”

By June, the LLOT project demonstrated error-free communications and successfully completed compatibility testing of the WSi-based LLOT receiver with the Lunar Lasercomm Space Terminal engineering unit.

“An amazing 2-month integration effort by Matt and Kevin and the rest of the LLOT team,” said Farr.

John Rush, director for the Technology and Standards Division of NASA’s Space Communications Office, visited the JPL ground station for a final check before the LLCD experiment started. Discussions included the list of challenges the team faced in getting ready on time. “The biggest challenge was the detectors where everyone agreed that the original detectors would not have worked. But the tungsten silicide detectors that STMD invested in saved the day,” Rush said.

“The new detectors now hold the world record for efficiency at 93 percent and for a mind-boggling 13 bits per photon,” Rush added. “This is an excellent example of how working together we can achieve things that we can’t achieve by ourselves.”

January 8, 2014

When a liquid-fueled rocket vaults into space, there’s a whole lot of sloshing going on inside those fuel tanks.

A better understanding of how that liquid behaves in zero gravity could help engineers build a better, safer rocket — one that could enable humans to explore asteroids, Mars, the moons of outer planets and, eventually, even deeper into space.

Now NASA expects that one of the many science experiments aboard the Cygnus commercial space freighter set to launch Wednesday from Wallops Island to the International Space Station will help toward that goal.

Having a skeleton crew aboard the International Space Station means forcing PhDs to pull double-duty as janitors, and sometimes to undertake dangerous space walks. NASA’s solution? Robonaut, or R2 as it’s called by shipmates on the International Space Station. Conceived of in 1997, the goal was to create a robot that would take on jobs that are too dangerous, or dull, for humans. It has been an engineering marvel: Engineers equipped R2 with arms and hands that can carry 40 pound payloads; 350 sensors feeding into 38 processors give it the ability to carefully manipulate a control panel, or even send a text message from an iPhone.

There was just one problem—it couldn’t move. R2 was either mounted on a pole or attached to a wheeled base, both non-starters in space. Now, NASA’s engineers have finally unveiled a bizarre-looking pair of legs that will help the robot crawl around.

Some call it “additive manufacturing,” and some call it “3D printing.” Whatever you call it, the technique of building things by layering material according to a 3D computer design is one of the hottest things going. People are doing it with plastics and metals and trying it with food and even human “tissue” in a race to build the perfect Star Trek replicator.

At Huntsville’s Marshall Space Flight Center, NASA scientists and engineers from the company Made in Space are building the first 3D printer to send to space. It will go the International Space Station next year aboard a SpaceX rocket. In the 2:30 video below, watch the machine build a small plastic clip that’s used frequently on the space station.

Printing in space will allow astronauts to replace a variety of small parts that break and save NASA the trouble and expense of launching multiple spares of multiple parts.

3-D Printing: NASA’s Next Frontier

3-D printing in space will radically enable the space industry. Building parts, structures, and tools in space will not only reduce launch mass and size constraints, it will also enable the capability to build parts when needed, on-demand.
Image credit: Made in Space

NASA is looking to boldly take 3-D printing where no 3-D printer has gone before. As NASA plans ventures deeper into space, flights that already cost millions of dollars will become more expensive. NASA could defray those rising costs by enabling crew members in space stations to print tools, replacement spacecraft parts and, eventually, even structures in which they could live on alien planets.

The aeronautical agency next year will fly the first 3-D printer to the International Space Station, where crew members will conduct the first 3-D printing tests in near zero gravity. Read more (+)

NASA JPL controls rover with Leap Motion, shows faith in consumer hardware

leapnasa01

If you think using the Leap Motion controller for playing air guitar and typing without a keyboard was cool, try using it to control a NASA rover. Victor Luo and Jeff Norris from NASA’s Jet Propulsion Lab got on stage at the Game Developers Conference here in San Francisco to do just that with the ATHLETE (All-Terrain Hex-Limbed Extra-Terrestrial Explorer), which was located 383 miles away in Pasadena. As Luo waved his hand over the sensor, the robot moved in kind, reacting to the subtle movements of his fingers and wrists, wowing the crowd that watched it over a projected Google+ Hangout.

NASA Plans to Capture Asteroid to Study and Find Ways to Deflect

 
 
The President’s 2014 budget recommendations for NASA last week included money to capture and explore an asteroid in a mission that could someday help protect the earth from impact. Charles Fishburne of WCVE Public Radio talks with Dr. Michael Gazarik, Associate Director of the NASA Space Technology Mission Directorate, about the purpose of the mission that may someday tame an asteroid headed towards earth.

Gazarik: Getting to an Asteroid Takes Technology, Community

 
Imagine a house-sized asteroid floating along in deep space, minding its own business, when along comes a robotic spacecraft with large solar panels that unleashes a capturing mechanism to catch and carry the asteroid on a two-year journey into the Earth-Moon system. There, it will remain stable in orbit for astronauts to visit, explore and collect samples to bring back to Earth.

Using advanced Solar Electric Propulsion (SEP) technologies is an essential part of future missions into deep space with larger payloads. The use of robotics and advanced SEP technologies like this concept of an SEP-based spacecraft during NASA mission to find, rendezvous, capture and relocate an asteroid to a stable point in the lunar vicinity offers more mission flexibility than would be possible if a crewed mission went all the way to the asteroid.

NASA’s asteroid initiative, announced as part of the President’s FY2014 budget request, integrates the best of NASA’s science, technology, and human exploration capabilities and draws on the innovation of America’s brightest scientists and engineers. It uses current and developing capabilities to find both large asteroids that pose a hazard to Earth and small asteroids that could be candidates for the initiative, accelerates our technology development activities in high-powered SEP and takes advantage of our hard work on the Space Launch System and Orion spacecraft, helping to keep NASA on target to reach the President’s goal of sending humans to Mars in the 2030s.
