3D printed items made in space come back to Earth
NASA today released a video of engineers unpacking a box of 3D parts that had been printed on ISS and then returned to Earth for testing.
Some more details here.
The goal, Bean continued, is for NASA to develop a database of mechanical properties to see if there’s any difference in mechanical strength between identical items made in space and on Earth. During the interview last month, Bean said that while NASA didn’t yet have any hard data, there had been initial indications from videos made on the space station, that the plastics used in the 3D printing there had “adhered differently” than those in the terrestrial test. “The astronauts trying to get the parts off the plate,” Bean said, found that the plastic “seemed to be a little more stuck than on the ground.” He said that while it was too early to tell if that was actually true, his guess was that if so, “it may be due to a lack of convection in zero-gravity.”
Understanding the engineering issues of 3D printing in space will make it possible for crews to carry far less cargo on long interplanetary journeys. Instead, they would carry a much smaller amount of raw material, which they could use to manufacture items as needed, then recycled.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

The ‘fabricators’ of science fiction are becoming reality. It’s truly exciting to watch the process of getting from ‘here’ to ‘there’ unfold.
