Re: 3D Printers

As reported elsewhere in this forum the Russians and many other groups, including the Mars Society have been running experiments like this.

Because this is a NASA sponsored and supervised experiment, I expect it will be given more attention than earlier experiments.

This update is happening in the 3D topic .... The connection ** might ** be possible construction of a habitat on Mars using 3D printing.

Further discussion of the experiment itself might be better matched with a topic about Mars Analog experiments.

This topic would be an excellent place for discussion of the 3D printers used to make the habitat, and the software used to direct the machines.

Re: 3D Printers

Scientist lays out plans for international lunar station and 3D luanr printing
https://www.spacedaily.com/reports/Scie … n_999.html
China is proposing to establish a multinational organization to take charge of the construction and operation of the International Lunar Research Station.

Wu laid out three major reasons China wants to intensify its lunar exploration efforts.

"The moon is an important clue to uncovering the secrets behind the origins of the universe, the solar system and terrestrial life. The Earth's natural satellite will become a 'transfer station' for humans to fly beyond it to other celestial bodies, and the resources on it will be meaningful to mankind's sustainable development," he said.

The scientist shared this information at the First International Deep Space Exploration Conference (Tiandu Forum), which opened in Hefei on Tuesday. The event was hosted by the Deep Space Exploration Laboratory with the participation of the Asia-Pacific Space Cooperation Organization, the China Space Foundation and the University of Science and Technology of China.

Wu Weiren, an academician of the Chinese Academy of Engineering and a leading scientist at the China National Space Administration, said the Chang'e 8 robotic probe - the third to be placed on the moon in the country's next lunar exploration endeavor - is set to land on the moon's South Pole to conduct on-site investigations of the environment and mineral composition at the landing site, and to check if some advanced technologies, 3D printing for example, can be done on the lunar surface using lunar materials in the future.

"If we wish to stay on the moon for a long time, we need to set up stations by using the moon's own materials," he said in a recent interview, ahead of the Space Day of China that falls on Monday.

"Lunar soil will be our raw material and it will be printed into construction units. Professors at several domestic universities, such as Tongji University in Shanghai and Xi'an Jiaotong University in Shaanxi province, have already begun studying the possible applications of 3D printing technology on the moon," he said.

Re: 3D Printers

Upcoming ISS project will test 3D materials for satellite manufacturing

https://www.spacedaily.com/reports/Inve … 7_999.html

As 3D printed rockets, car parts, and even homes begin to hit the market on Earth, L3Harris Technologies aims to leverage the International Space Station (ISS) National Laboratory in its search for durable materials to 3D print satellite components. Before 3D printed materials can be used to build more sustainable and efficient parts for spacecraft, they must be tested to ensure they can withstand the harsh environment of low Earth orbit (LEO).

Among the payloads launching on SpaceX's upcoming 27th Commercial Resupply Services (CRS) mission is a project to test an L3Harris-designed 3D printed radio frequency (RF) circuit and various 3D printed material samples. The project is a continuation of a 2021 experiment on the ISS that collected two months of data. This time, L3Harris will also test photonic material for a new technology called photonic integrated circuits. Used for satellite communications and similar to computer chips, these circuits utilize light instead of electrons in conventional electronics, similar to how light carries information in fiber optic cables for phone and internet data.

"We're excited to test the 3D printed materials for six months and compare the new results with previous ISS experiments and ground tests," said Arthur C. Paolella, senior scientist and technical fellow with L3Harris, an aerospace and defense industry leader. "The ability to 3D print materials for use in space opens up new possibilities for satellite design and construction while making spacecraft manufacturing more cost-effective and efficient."

Eduardo Rojas, director of the Wireless Devices and Electromagnetics Laboratory at Embry Riddle Aeronautical University, and his students are assisting with the experiment. The investigation will utilize the MISSE Flight Facility (owned and operated by ISS National Lab Commercial Service Provider Aegis Aerospace) mounted to the exterior of the ISS. There, the material samples will experience the harshness of space in the ultimate test of their durability. The materials will be subjected to various conditions, including extreme temperatures and radiation, to validate their performance in the same environment where the satellites will operate.

"While we can test the durability of these materials on Earth against one or two of these factors at a time, on the ISS, we can test every potential hazard-and all at once," Paolella said.

Re: 3D Printers

NASA Locks 4 Volunteers Into 3D-Printed Virtual 'Mars' For Over a Year

https://science.slashdot.org/story/23/0 … ver-a-year

Four volunteers will spend the next 378 days in a simulation of Mars, facing harsh, realistic challenges in tight quarters under NASA's watchful eye in preparation for a real-life mission to the red planet.

https://nypost.com/2023/06/27/nasa-lock … er-a-year/

Nasa 3D-printed the 1,700-square-foot facility, dubbed Crew Health and Performance Exploration Analog -- or CHAPEA. It will be the longest analog mission in the agency's history. The habitat -- named Mars Dune Alpha -- will feature a kitchen, private crew quarters, and two bathrooms, with medical, work, and recreation areas. The crew will be expected to carry out "mission activities," like collecting geological samples, exercising, and practicing personal hygiene and health care, with minimal contact with their family and loved ones, according to NASA.

To capture the true essence of life on our neighboring planet, the crew must work through "environmental stressors," including limits on resources, periods of isolation, and equipment failures.

Re: 3D Printers

Researchers create highly conductive metallic gel for 3D printing

https://www.eurekalert.org/news-releases/994166

Researchers have developed a metallic gel that is highly electrically conductive and can be used to print three-dimensional (3D) solid objects at room temperature.

“3D printing has revolutionized manufacturing, but we’re not aware of previous technologies that allowed you to print 3D metal objects at room temperature in a single step,” says Michael Dickey, co-corresponding author of a paper on the work and the Camille & Henry Dreyfus Professor of Chemical and Biomolecular Engineering at North Carolina State University. “This opens the door to manufacturing a wide range of electronic components and devices.”

To create the metallic gel, the researchers start with a solution of micron-scale copper particles suspended in water. The researchers then add a small amount of an indium-gallium alloy that is liquid metal at room temperature. The resulting mixture is then stirred together.

Re: 3D Printers

CHAPEA: Going to Mars without leaving Earth

https://www.spaceflightinsider.com/orga … ing-earth/

Crew Health and Performance Exploration Analog, or CHAPEA, is a series of analog missions that simulate year-long stays on Mars in a fully 3D printed habitat called Mars Dune Alpha, situated at NASA’s Johnson Space Center in Houston.

The design of the 1,700 square-foot habitat was carefully planned to provide areas for living and working for four crewmembers. It contains individual private quarters, a kitchen, a gym, a recreation area, a workspace, a greenhouse for crop growth activities, an area to run experiments and two bathrooms.

All of these functional spaces needed to be contained in an area about the size of a single-family home.

ICON, a company at the forefront of developing advanced construction technologies utilizing 3D printing robotics, software and cutting-edge materials, was responsible for the construction of Mars Dune Alpha.

In the construction process, ICON used a material similar to what might be utilized on an actual 3D printed Mars habitat — a regolith-based mixture.

Additive manufacturing, specifically 3D printing, showcases the promising technique of utilizing Martian resources on-site known as in-situ resource utilization. This approach eliminates the necessity of launching large quantities of building materials across multiple flights, which is prohibitively expensive.

In order to maximize the resemblance to an actual Martian habitat environment, NASA incorporated various environmental stressors into the analog mission. These include resource limitations, isolation, equipment failure and demanding workloads.

The significance of maintaining a busy, productive and purposeful crew for the duration of one year cannot be underestimated.

Introducing Magic: Analog Sky’s New 3D Printed Binoculars for Astronomy

https://www.universetoday.com/163264/in … astronomy/

When it comes to deep sky observing versus portability, we’ve all been there. How do you balance the trade-off between big complicated optics, with something basic and simple to use? We’ll make a small confession: while big light bucket optics have their place in astronomy, only binoculars give you a true view of the sky.
