NASA proves 3D printing is headed to the stars

3D-printed space technology is no longer science fiction, as NASA and other space companies are making it a reality.
Engineers and researchers at the Ames Research Center are already working with 3D printing technology to make it applicable for use in both space travel and the study of our universe, according to a recent CNET report.

Earlier this year, MakerBot, one of the foremost producers of 3D printers, confirmed that NASA engineers were using the technology to build parts for models, including the Mars Rover Curiosity. NASA is now the company’s biggest customer, the company told Forbes.

The Right-Wing Mars Guru: Is Robert Zubrin America’s Best Hope for Colonizing the Red Planet?

When you think of people who urge humanity to go to the stars, you tend to think of cheery liberal icons like Carl Sagan or Neil deGrasse Tyson. But Newt Gingrich had to get his starry-eyed and much-ridiculed ideas about space exploration from someone, and it certainly wasn’t any of those guys.

Enter Robert Zubrin, the right-wing bulldog for space travel. Trained as a nuclear engineer, he’s spent more than 20 years pushing for the colonization of Mars through books like 1996′s The Case for Mars; advocacy through the Mars Society, which he founded and leads; and relationships with people like Newt Gingrich, whom he advised on space policy in the 1990s. He’s not a hardcore Republican ideologue by any means, but he regularly rails against environmentalists for being “anti-growth”, writes for the National Review, and proudly wears his American nationalism.

Zubrin, who just published a new e-book called Mars Direct: Space Exploration, the Red Planet, and the Human Future, spoke to me by telephone from his home in Colorado about why to go to Mars, how we might get there, and why it will be important to defend private property and entrepreneurship on the fourth planet from the sun.

The Engadget Show 41: ‘Space’ with NASA, SETI, Liftport and Mary Roach

The Engadget Show 41 'Space' with NASA, SETI, Liftport and Mary Roach

“Space,” a great man once said, “is the place.” Over the centuries, the cosmos have inspired mankind’s imagination and innovation, in pursuit of that final frontier. The past few decades, however, have seen a fading of such romantic pursuits, a phenomenon no better illustrated than with the end of NASA’s shuttle program. So, where does that put us in 2013? This month, we travel the country in pursuit of an answer, speaking to some of the top minds in the public and private space games.

We kick things off with a profile of LiftPort, a commercial space endeavor operating out of a small garage in rural Washington State that has been funding its dreams of space elevators through crowdfunded Kickstarter campaigns. Next, we head out to Cape Canaveral in Florida, where Swamp Works has set up shop in an old Apollo training facility. NASA scientists will tell us about some of the organization’s far-out plans for getting to Mars and back and 3D printing structures on lunar and planetary surfaces once we arrive.

NASA’s Tom Rivellini joins us to discuss “seven minutes of terror,” and what it takes to land a rover on the surface of Mars. We’ll also pay a visit to NASA’s Ames facility to discuss why space travel is still important to life on Earth. And while out in the San Francisco Bay Area, we swing by the SETI institute to find out how the organization is actively looking for extraterrestrial life in the universe, including a discussion with SETI founder and developer of the Drake Equation, Frank Drake.

Next up, things get a bit animated with Packing for Mars author Mary Roach, who will discuss the grosser side of manned space travel, while professional prognosticator (and sometimes rock musician) John Roderick kicks off his new reoccurring segment by explaining how space exploration helps him get out of bed in the morning.

We also take a closer look at how the commercial space sector is pushing exploration forward with Google Lunar X Prize senior director, Alexandra Hall, a lunar rover team at Carnegie Mellon, the Space Angels Network VC firm and Laser Motive, which is working on powering crafts through lasers. Then we’ll cap things off by speaking to two former movie costume makers who have launched their own commercial space suit companies. Excited? Take one small step with us after the break.

Hosts: Tim Stevens, Brian Heater
Guests: Frank Drake, Jill Tarter, Mary Roach, John Roderick, Tom Rivellini, Alex Hall, David Morrison, many, many more
Producer: Ben Harrison

NASA Considers Dragging Asteroids to the Moon

image

The Keck Institute for Space Studies wants an asteroid orbiting the moon as early as next decade.

When most of us think of asteroids, we probably imagine massive death rocks hurtling through space to threaten our world and our lives. When scientists think about asteroids, however, it’s not always about how Bruce Willis could best blow them up to an Aerosmith soundtrack. Asteroids hold a great deal of scientific potential, but with our limitations on space travel, it’s exceedingly difficult to reach them and complete the necessary research. What’s a rocket scientist to do? There’s one surprisingly sensible solution: if NASA can’t get to the mountain, bring the mountain to NASA. Or more specifically, drag it into orbit around the moon.

NASA is currently considering a plan put together by the Keck Institute for Space Studies to literally drag a small asteroid into high lunar orbit. The plan, if implemented, would begin by sending a slow-moving, robotic craft to a target asteroid approximately seven meters wide. After making some final calculations, the craft would catch the asteroid in a 10 by 15 meter bag and return to a high lunar orbit. The Keck Institute believes this project could be completed relatively easily by the 2020s, and would cost approximately $2.6 billion, only slightly more than the Curiosity Mars rover project.

There are actually quite a few benefits to the Keck Institute’s plan. The Obama administration has previously expressed interest in exploring near-Earth asteroids, but the required long-term mission would place teams well beyond the reach of any rescue. Bringing space rocks back home would provide all the scientific benefits of an asteroid mission without putting lives in immediate jeopardy. Having a handy orbiting asteroid could also have applications for scientists learning how to extract minerals and fuel, which might set the stage for future exploration missions to Mars and beyond. And if something were to go wrong, an asteroid seven meters wide is nowhere near the planet-killer size that scientists usually keep an eye out for.

It will still be at least a decade before this plan bears fruit, if it’s implemented at all, so we can’t say for sure what will happen. Even so, a future in which asteroids orbit our moon, and are frequently visited by humans? That’s a pretty cool future to imagine, whether or not we have our jetpacks by then.

A new future for NASA in technology R&D?

Comment

Email Print

Last month, hundreds of Houstonians went outside in the daylight to watch as a plane attached to the space shuttle flew over the city. It was a bittersweet moment for all who watched — a reminder that the shuttle program has been officially canceled, leaving many Americans, including us, wondering what is NASA going to do in the future.

Over the past four years, the Obama administration has put together a plan to better link NASA and private industry and, with NASA’s support, several very ambitious companies have successfully launched privately financed spaceships, albeit not yet manned. But alongside the shuttle going into retirement and the cancelation of the Constellation program, Obama and Congress have put plans for federally-funded, manned space travel on hold due to overall budgetary restrictions.

A  new policy report from the Baker Institute describes how focused research and development (RD) of new technologies — such as nanotechnology — could be the future of NASA. Nanotechnology has great potential for advancing many traditional NASA technologies beyond their current state. Most notably, nano-engineered materials are known for their strength, lightness and thermal robustness, making them ideal candidates for inclusion in future aircraft and space vehicles. Additionally, nanoscale elements have shown great promise for faster integrated electronics and more sensitive detectors.

According to the report, “the United States currently lacks a national space policy that ensures the continuity of research and programs that build on existing capabilities to explore space.” The absence of a mission-directed goal has hit NASA, and more specifically centers like Johnson Space Center (JSC), particularly hard. Establishing specific objectives for basic research, and aligning these objectives with a nationally recognized plan for space exploration, could help to stabilize congressional appropriations for NASA in the long-term. At home, reinvesting in basic sciences could help find a new role for JSC after the termination of the shuttle program.

Through grants and academic collaborations, NASA could work toward sustained relationships and programming to integrate next-generation technologies with its current infrastructure. Without a consistent plan for our nation’s future in space, and a continued focus on basic research, we risk losing ground to other countries with a more resolved interest and greater financial resources for spaceflight.

Kirstin Matthews, Ph.D., is a fellow in science and technology policy at the Baker Institute. Her research focuses on the intersection between traditional biomedical research and public policy. Matthews’ current projects include the Baker Institute International Stem Cell Policy Program, the Civic Scientist Lecture Series and policy studies in research and development funding, genomics and climate change. Kenneth Evans is a graduate intern for the Science and Technology Policy Program.

Crowds cheer at NASA Langley test

HAMPTON — After a 15-second countdown and final call of “release,” the full-sized model spacecraft dropped 25 feet with a loud “sploosh” as water flew and spectators cheered.

Attendees of NASA’s Langley Research Center open house on Saturday witnessed a vertical drop test of a model of the Orion multipurpose crew vehicle that NASA is designing as a safer way to send humans beyond low-Earth orbit. Orion is reminiscent of Apollo spacecraft, but with more technological advancements, according to the NASA website.

“It’s pretty impressive to see it in person,” astronaut Anna L. Fisher said about the test. Fisher, 63, spent eight days in space aboard Space Shuttle Discovery in 1984.

The drop into the research center’s “Hydro Impact Basin,” or pool, simulated the spacecraft’s return to Earth on calm seas and with one of three parachutes failing, said Michael Greenwood, SPLASH project chief engineer. Data picked up by sensors on the capsule will be used in computer models to do more tests in a virtual world where it’s more efficient and less expensive, he said.

Fisher, who lives in Houston, is working on the displays for people to interact with or command the spacecraft. While she lamented the end of the shuttle program, she’s excited about the future of space travel and foresees a day when low-orbit travel will become affordable.

“It’s just so awesomely beautiful,” Fisher said about space.

Many researchers hope Orion will eventually take astronauts to Mars. Greenwood would like a return to the moon. The testing site is where astronauts trained to walk on the moon.

Nicholas Caison, 16, of Hampton had been waiting months to see the test. He’s always loved space and wanted to be an astronaut as a kid. The Virginia Air Space Center summer volunteer was disappointed to see the end of the shuttle era but wondered if Orion could make it to Mars.

“It’s history right here in the making,” Caison said.

Lindsey Gnik, 12, and Katie Ferguson, 16, of Newport News said the test was their highlight of the open house, which marked NASA Langley’s 95th anniversary. Ferguson, who wants to be a fighter pilot, came to learn about experiments and technology at NASA Langley. Of the 10,000 estimated in attendance, several youth said another favorite was the model test at the wind tunnel.

Gnik, who wants to be a marine biologist, noticed how the impact of the drop sent water gushing over audience members’ feet.

“It was really cool,” Gnik said.

By the numbers

Orion model drop test on Saturday:

15-second countdown

25-foot drop

About 20 mph

NASA Astronaut Mae Jemison Inspires

Mae Jemison has seen the Earth from outer space.

As a NASA astronaut, she was the first black woman to travel into space, orbiting the Earth aboard the space shuttle Endeavour in 1992.

That gives her a global perspective, one that she thinks businesses need to adopt, too.

“I think that in the world today we need to pay attention to what is happening and understand that we have choices, and our choices should not be small and narrow and selfish,” said Jemison, who spoke in Richmond on Tuesday night at Owens Minor Inc.’s seventh annual health care supplier diversity symposium.

Jemison had just traveled from another conference on space travel, part of a project she is leading to ensure that within the next 100 years we can send humans to another solar system.

“We should really look at how we progress as a species,” Jemison said in an interview before her speech. “Businesses are part of it.”

Nearly 300 people from around the nation are attending the two-day conference at the Richmond Marriott, more than half of them representing women- and minority-owned suppliers in the health care industry, along with representatives from health providers such as Bon Secours Richmond Health System and VCU Health System.

This year’s conference focuses on how other suppliers, especially women- and minority-owned firms, can find opportunities in the global market, said Angela Wilkes, Owens Minor’s director of supplier diversity and sustainability.

Owens Minor, a Hanover County-based distributor of medical products, recently expanded into international markets by acquiring a European-based firm.

“When we looked at supplier diversity historically in health care, there was a very local focus,” Wilkes said.

“We looked at economic development within a community. With changes in health care and in the global economy, it makes good business sense for women- and minority-owned businesses to expand their horizons,” Wilkes said.

Jemison, who was born in Alabama, grew up in Chicago, trained as a medical doctor and worked for the Peace Corps as a physician in Africa. She was an astronaut for six years and then founded her own research company, The Jemison Group.

She also is an advocate for science, technology, engineering and math education.

Businesses should embrace diversity as they look to grow in a global marketplace, she said.

“I think you don’t have to make the case for diversity in business,” she said. “It should be very, very clear. As we look at our world right now, it is made up of lots of different people, and there is no way to really provide for their needs unless you have a broad perspective.”
