A 3-D printer intended for the International Space Station has passed its NASA certifications with flying colors — earning the device a trip to space sooner than expected. The next Dragon spacecraft, scheduled to launch in August, will carry the Made In Space printer on board.
“Passing the final tests and shipping the hardware are significant milestones, but they ultimately lead to an even more meaningful one – the capability for anyone on Earth to have the option of printing objects on the ISS. This is unprecedented access to space,” stated Made In Space CEO Aaron Kemmer.
The device was originally supposed to launch not on this next Dragon flight, but the one after that. But it recently completed several tests looking at everything from vibration to human design to electromagnetic interference, and was deemed enough of a “minimal risk” to get moved up a slot.
This 3-D printer will be the first to be used in orbit. Officials have already printed out several items on the ground to serve as a kind of “ground truth” to see how well the device works when it is installed on the space station. It will be put into a “science glovebox” on the International Space Station and print out 21 demonstration parts, such as tools.
“The next phase will serve to demonstrate utilization of meaningful parts such as crew tools, payload ancillary hardware, and potential commercial applications such as cubesat components,” Made In Space added in a statement.
Once fully functional, the 3-D printer is supposed to reduce the need to ship parts from Earth when they break. This will save a lot of time, not to mention launch costs, the company said. It could also allow astronauts to manufacture new tools on the fly when “unforeseen situations” arise in orbit.
Imagine you’re a researcher at a cocktail party. You meet Carl Sagan (Carl Sagan!) and he hands you a novel. And it turns out that you are the inspiration for the major character in that book.
What was SETI researcher Jill Tarter’s reaction when this actually happened and she heard about Ellie, the protagonist in Contact?
“I said, ‘Look. Here’s the deal. As long as she doesn’t eat ice cream cones for lunch, nobody’s going to think it’s me.’ That was the thing that was sort of my most peculiar habit of the time,” Tarter recalls in this new video for PBS.
If you can think of all the media attention that surrounded the reboot of Cosmos, imagine that it’s 1997 and Contact has just been made into a movie. Tarter became a celebrity overnight, and describes the impact on her life. But she also explains why searching for life beyond Earth has relevance.
Tarter’s video is just one of several featured in the show “”The Secret Life of Scientists and Engineers.” To get the full story on Tarter’s links to Contact, check out this Universe Today story from 2012 where she reflected on the 15th anniversary of the movie.
Ever notice how the brilliant star Sirius appears to change colors right before your eyes? Astrophotographer Roshaan Bukhari from Pakistan wanted to see for himself how this twinkling star changes in color due to the effects of our atmosphere as its light gets refracted and he did a little experiment with his telescope and camera. What resulted was a unique and colorful astrophoto!
“I pointed my telescope to sharply focus on Sirius and put my DSLR camera to 2 second exposure while holding it near the eyepiece and focusing Sirius from the camera viewfinder as well,” Roshaan told Universe Today via email. “I started shaking the telescope in a circular manner by holding it from the eyepiece so that Sirius was dancing all over the eyepiece in an ‘O’ shape. That’s when I pressed the camera shutter button and the shutter remained open for 2 seconds, recording the colours and the pattern of Sirius within the eyepiece.”
Roshaan said he did enhance the contrast to bring the trails out more clearly, but the color saturation and hues have not been altered in any way. The changes in color in just a two-second exposure are really amazing!
Roshaan shared how astronomy and astrophotography in Pakistan is becoming a “blooming field now” — which we are very happy to hear! “And I’m very happy to say that I am a part of it!” he said, adding, “I’m one of the biggest fans of Universe Today and have been listening to it’s podcasts on iTunes since i got my first iPhone back in 2008.”
Here are few more images from Roshaan Bukhari under Pakistan skies:
How does the look of the Moon change during the night? These images of the Moon — taken 7 hours apart — were shot through Roshaan’s telescope with his mobile phone camera using the handheld afocal method!
Phase of the moon at 7 pm was 96.8%, while at 2 am it was 97.5% (rate of change of lunar phase turns out to be 0.7% in 7 hours, figures estimated from Stellarium).
Roshaan said the quality of the images is not that great since he took them while there a lot of dust was up in the atmosphere due to some strong winds, but we think they look great!
Thanks to Roshaan for sharing his images from Pakistan.

KENNEDY SPACE CENTER, FL – Boeing unveiled a full scale mockup of their CST-100 commercial ‘space taxi’ on Monday, June 9, at the new home of its future manufacturing site at the Kennedy Space Center located inside a refurbished facility that most recently was used to prepare NASA’s space shuttle orbiters for missions to the International Space Station (ISS).
The overriding goal is restart our country’s capability to reliably launch Americans to space from US territory as rapidly and efficiently as possible.
The CST-100 crew transporter was revealed at an invitation only ceremony and media event held on Monday, June 9, inside the gleaming white and completely renovated NASA processing hangar known as Orbiter Processing Facility-3 (OPF-3) – and attended by Universe Today.
The huge 64,000 square foot facility has sat dormant since the shuttles were retired following their final flight in July 2011 and which was commanded by Chris Ferguson, who now serves as director of Boeing’s Crew and Mission Operations.
Universe Today was invited to be on location at KSC for the big reveal ceremony headlining US Senator Bill Nelson (FL) and Boeing executives including shuttle commander Ferguson, for a first hand personal inspection of the private spaceship and also to crawl inside and sit in the seats of the capsule designed to carry American astronauts to the High Frontier as soon as 2017.
“Today we celebrate this commercial crew capsule,” said Sen. Nelson at the unveiling ceremony. “This vehicle is pretty fantastic and the push into space the CST-100 represents is historic.”
“We are at the dawn of a new Space Age. It’s complemented by the commercial activities going to and from the space station and then going outside low Earth orbit [with Orion], as we go to the ultimate goal of going to Mars. There is a bright future ahead.”
The purpose of developing and building the private CST-100 human rated capsule is to restore America’s capability to ferry astronauts to low-Earth orbit and the space station from American soil aboard American rockets, and thereby end our total dependency on the Russian Soyuz capsule for tickets to space and back.
Boeing’s philosophy is to make the CST-100 a commercial endeavor, as simple and cost effective as possible in order to quickly kick start US human spaceflight efforts. It’s based on proven technologies drawing on Boeing’s 100 year heritage in aviation and space.
“The CST-100, it’s a simple ride up to and back from space,” Ferguson told me. “So it doesn’t need to be luxurious. It’s an ascent and reentry vehicle – and that’s all!”
So the CST-100 is basically a taxi up and a taxi down from LEO. NASA’s complementary human space flight program involving the Orion crew vehicle is designed for deep space exploration.
Read my exclusive, in depth one-on-one interviews with Chris Ferguson – America’s last shuttle commander – about the CST-100; here and here.
The stairway to America’s future human access to space is at last literally taking shape from coast to coast.
Sen. Nelson, a strong space exploration advocate for NASA and who also flew on a space shuttle mission on Columbia back in January 1986, was the first person to climb the steps and enter the hatch leading to Boeing’s stairway to the heavens.
“This is harder to get in than the shuttle. But the seats are comfortable,” Nelson told me as he climbed inside the capsule and maneuvered his way into the center co-pilots seat.
Nelson received a personal guided tour of the CST-100 spaceship from Ferguson.
The capsule measures 4.56 meters (175 inches) in diameter.
The media including myself were also allowed to sit inside the capsule and given detailed briefings on Boeing ambitious plans for building a simple and cost effective astronaut transporter.
The vehicle includes five recliner seats, a hatch and windows, the pilots control console with several attached Samsung tablets for crew interfaces with wireless internet, a docking port to the ISS and ample space for 220 kilograms of cargo storage of an array of equipment, gear and science experiments depending on NASA’s allotment choices.
The interior features Boeing’s LED Sky Lighting with an adjustable blue hue based on its 787 Dreamliner airplanes to enhance the ambience for the crew.
Boeing is among a trio of American aerospace firms, including SpaceX and Sierra Nevada Corp, vying for the next round of contracts to build America’s ‘space taxi’ in a public/private partnership with NASA using seed money under the auspices of the agency’s Commercial Crew Program (CCP).
Since 2010, NASA has spent over $1.5 billion on the commercial crew effort.
Boeing has received approximately $600 million and is on target to complete all of NASA’s assigned CCP milestones in the current contract phase known as Commercial Crew Integrated Capability initiative (CCiCAP) by mid-2014.
Boeing’s CST-100 crew capsule reveal on June 9 comes just two weeks after SpaceX CEO Elon Musk’s Hollywoodesqe glitzy live show on May 29 – pulling the curtain off his firms ‘Dragon’ crew vehicle entry into NASA’s commercial crew program.
NASA officials say that the next round of contracts aims at building a human rated flight vehicle to dock at the ISS by late 2017.
The next contract phase known as Commercial Crew Transportation Capability (CCtCap) will result in one or more awards by NASA later this summer around August or September .
Sen. Nelson expressed his hope that the competition will continue since Congress appears likely to finally approve something near the President’s CCP funding request of over $800 million in the Fiscal 2015 NASA budget.
“With about $800 million, that’s enough money for NASA to do the competition for at least two and maybe more,” said Nelson. “That of course is up to NASA as they evaluate all the proposals.”
NASA had hoped to fly the first commercial crew missions in mid-2015.
But repeated CCP funding cuts by Congress since its inception in 2010 has already caused significant delays to the start of the space taxi missions for all three companies contending for NASA’s commercial crew contracts.
In fact the schedule has slipped already 18 months to the right compared to NASA’s initial plans thus forcing the agency to buy more Soyuz seats from the Russians at a cost of over $70 million each.
The reusable capsule will launch atop a man rated United Launch Alliance (ULA) Atlas V rocket.
It was glorious to be seated inside America’s next spaceship destined to carry humans.
The next generation of US human spaceflight is finally coming to fruition after a long down time.

“Let me take you on a little trip … we’re gonna travel faster than light,” the Kinks sang 42 years ago. Well, maybe this was the warp ship they were dreaming of.
Howard White (who we can confirm was a NASA employee as late as 2013) has a vision for a warp-drive ship that he’s been working on for a few years. White, whose biography describes him as the advanced propulsion theme lead for NASA’s engineering directorate, recently released his new vision of the spaceship in collaboration with artist Mark Rademaker. The result is gorgeous. More pictures below the jump.
As for how realistic his concept is, as non-physicists it’s tough for us to evaluate. Essentially, White is proposing some modifications to this warp drive concept by Miguel Alcubierre, which would create a zone of warped space time in front of and behind the spaceship to get it to move quickly. But White has been making the professional and media circuit in recent years touting his theories, and they are getting attention.
Remember yesterday when we mentioned two X-class flares erupting from the Sun within the space of about an hour? We probably should have waited a bit and gone for the trifecta: this morning the same active region flared yet again, making it three high-powered flares within a single 24-hour period.
(And to think this active region has only just come around the corner!)
On June 10, 2014, AR2087 announced its arrival around the southwestern limb of the Sun with an X2.2 flare at 11:41 UT (7:41 a.m. EDT). Then, just over an hour later, another eruption: an X1.5 flare at 12:55 UT. This got pretty much everyone’s attention… here comes 2087!
Perhaps figuring third time’s a charm, the active region blazed with a third flare this morning at 9:05 UT (5:05 a.m. EDT). “Only” an X1-class, it was the weakest of the three but AR2087 still has plenty of time for more as it makes its way around the Sun’s face — all the while aiming more and more our way, too.
Here’s a video of SDO observations showing the two June 10 flares:
X-class flares are the strongest in the letter-classification of solar flares, which send blasts of electromagnetic energy out into the Solar System. While these most recent three are low on the X-scale, they may result in increased auroral activity — especially since it appears that the first two were followed by a pair of CMEs that “cannibalized” each other on their way out. The resulting merged cloud of charged particles is expected to nick Earth’s magnetic field on Friday, June 13. (Source: Spaceweather.com)
No CME has been observed from the June 11 flare, but again: AR2087 hasn’t left the stage yet. Stay tuned!

Brazilian astronomers have discovered some 300+ star clusters that were largely overlooked owing to sizable obscuration by dust. The astronomers, from the Universidade Federal do Rio Grande do Sul, used data obtained by NASA’s WISE (Wide-Field Infrared Survey Explorer) space telescope to detect the clusters.
“WISE is a powerful tool to probe … young clusters throughout the Galaxy”, remarked the group. The clusters discovered were previously overlooked because the constituent stars are deeply embedded in their parent molecular cloud, and are encompassed by dust. Stars and star clusters can emerge from such environments.
The group added that, “The present catalog of new clusters will certainly become a major source for future studies of star cluster formation.” Indeed, WISE is well-suited to identify new stars and their host clusters because infrared radiation is less sensitive to dust obscuration. The infrared part of the electromagnetic spectrum is sampled by WISE.
Historically, new star clusters were often identified while inspecting photographic plates imaged at (or near) visible wavelengths (i.e., the same wavelengths sampled by the eye). Young embedded clusters were consequently under-sampled since the amount of obscuration by dust is wavelength dependent. As indicated in the figure above, the infrared observations penetrate the dust by comparison to optical observations.
The latest generation of infrared survey telescopes (e.g., Spitzer and WISE) are thus excellent instruments for detecting clusters embedded in their parent cloud, or hidden from detection because of dust lying along the sight-line. The team notes that, “The Galaxy appears to contain 100000 open clusters, but only some 2000 have established astrophysical parameters.” It is hoped that continued investigations using WISE and Spitzer will help astronomers minimize that gap.
Gamma-ray bursts (GRBs) represent the most powerful explosions in the cosmos, sending out as much energy in a matter of seconds as our Sun will give off during its entire 10-billion-year lifespan.
These powerful explosions are thought to be triggered when dying stars collapse into jet-spewing black holes. Yet no one has ever witnessed a GRB directly. Instead astronomers are left to study their fading light.
But some GRBs mysteriously seem to have no afterglow. Now, observations from the Atacama Large Millimeter/submillimeter Array (ALMA) are shedding light on these so-called dark bursts.
One possible explanation is that dark bursts explode so far away their visible light is extinguished due to the expansion of the Universe. Another possible explanation is that dark bursts explode in galaxies with unusually thick amounts of interstellar dust, which absorb a burst’s light.
Neither explanation, however, seems likely as astronomers anticipate that GRB progenitors — massive stars — are found in active star-forming regions surrounded by large amounts of molecular gas. But unfortunately there has never been an observational result to back up this theory either.
So astronomers have been working hard to better understand GRBs by studying their host galaxies. Now, a Japanese team of astronomers led by Bunyo Hatsukade from the National Astronomical Observatory in Japan, has used ALMA to report the first-ever map of molecular gas and dust in two galaxies that were previously rocked by GRBs.
Hatsukade and colleagues detected the radio emission from molecular gas and dust in two dark host galaxies — GRB 020819B and GRB 051022 — at about 4.3 billion and 6.9 billion light-years away, respectively.
“We have been searching for molecular gas in GRB host galaxies for over 10 years using various telescopes around the world,” said Kotaro Kohno from the University of Tokyo in a press release. “As a result of our hard work, we finally achieved a remarkable breakthrough using the power of ALMA. We are very excited with what we have achieved.”
Watch the video below for an artist concept animation of the environment around GRB 020819B based on ALMA observations:
The telescope’s high sensitivity enabled the team of astronomers to detect the emission from molecular gas, as opposed to most telescopes, which can only probe absorption along the line of sight. This combined with its high spatial resolution provided the first detailed map of the molecular gas and dust throughout a GRB host galaxy.
Surprisingly, less gas was observed than expected, and correspondingly much more dust. The ratio of dust to molecular gas at the GRB site is 10 times higher than in normal environments.
“We didn’t expect that GRBs would occur in such a dusty environment with a low ratio of molecular gas to dust,” said Hatsukade. “This indicates that the GRB occurred in an environment quite different from a typical star-forming region.”
The research team thinks the high proportion of dust compared to molecular gas is likely due to the intense ultraviolet radiation from the young, massive stars, which will break up any molecular gas while leaving the dust relatively undisturbed.
It’s becoming clear that dust absorbs the afterglow radiation, causing these dark gamma-ray bursts. The team plans to carry out further observations and is excited to use ALMA’s incredible sensitivity to probe other host galaxies.
