National Aeronautics and Space Administration as well as other private businesses are dedicated to sending people to Mars in the relatively near future. After traveling for about 9 weeks to make it to the Red Earth, these groundbreaking astronauts would want to get to work with establishing the community and investigating the earth. The process of having settled in appears like it’ll be expedited, as bots are being developed that will assemble roads and fundamental edifices before astronauts arrive. Behrokh Khoshnevis, a NASA engineer in the University of Southern Ca, is doing work for a long time on robots that can 3D print structures by extruding concrete, and is leading the investigation to to create the technology to Mars.

Khoshnevis’ process of printing structures continues to be named “ contour ” It works much the same fashion as 3D publishing that is traditional, except the machines are much bigger and instead of extruding plastic, it uses concrete. It’s the fact that construction material that’s now introducing the biggest challenge. Concrete patching recipes may vary, but it generally contains course aggregate like a cement binder, fine aggregate like sand, stone, chemical additives, and recycled materials. Soil on Mars has a great deal of sulfur articles, about four times as much as our planet.

Even with reformulating the formula to take into account the sulfur, the mud on Mars is not far more fine than on Earth and is not going easily through the extruders. Earth sand has eroded more make it feeling nice and smooth. While Red Planet does encounter dust demons that are big, the Martian sand doesn’t get nearly as much erosion as our beach sand.

The near lack of weather and an environment on Mars has some edges, as can the gravity that is highly reduced compared to Earth. The 3D printed buildings will not have to withstand strong winds or gravitational pressure, that may increase the durability of the infrastructure.

NASA has announced Phase 2 of its 3D-printed habitat challenge.

In Phase 1, design a construction which could be 3D printed using resources on Mars and competitions were challenged to dream up

NASA is offering $1.1 million in prize money in Phase 2 of the 3D-Printed Habitat Challenge for new ways to construct houses where future space explorers can live and work. The three-component competition asks citizen inventors to use easily available and recyclable materials for the raw material to print habitats.

Phase 2 is about building while Phase 1 was about architecture. It requests rivals to “show a recycling system that can create structural parts using terrestrial and space-based stuff and recyclables,” according to NASA’s Centennial Challenges site. Competitions in this period should construct a system that can in fact make the stuff needed to construct the constructions dreamed up in Phase 1.

Phase 2 competitors could develop a method to take the Martian ice and use a 3D printer to construct the ice into the sections needed to really make that layout.

Phase 2 focuses on the substance technologies needed to fabricate structural components from a mixture of indigenous materials and recyclables, or indigenous substances alone. NASA may use these technologies to construct shelters for future human explorers to Mars. On Earth, these same abilities may be used to create affordable housing where access to conventional building materials and abilities is restricted or wherever it truly is desired.

Three of Bradley University’s core values, “Innovation, collaboration and experiential learning, are at the heart of the 3D-Printed Habitat Challenge with Caterpillar and NASA, ” said Bradley University President Gary Roberts. “The challenge create relationships, provides an unparalleled opportunity for faculty and students to network and explore new ideas as they partner in creating solutions for our world and beyond.”

Registration for Phase 2 is now open; teams have until Jan. 31, 2017 to sign up. At ground facilities being proven by Caterpillar in Peoria the challenge will culminate in an earth contest in August 2017. Phase 3 will concentrate on manufacture of entire habitats. Phase 1 of the 3D- Printed Habitat Challenge, a design competition, was completed in 2015.

Mars City Design

Mars City Design is a collaboration of engineers, architects and visionaries with a goal of taking steps toward realising the technology requires to sustain human civilisation on Mars. Described as a ‘Human Movement’ it was born from the vision of Vera Mulyani, who always dreamt of becoming an architect of Mars. Their mission is mission is to design the blueprint for sustainable cities on Mars.

The Mars City Design Competition has taken entries from around the world, with the top 3 invited to develop their ideas further at a summer workshop held at the University of Southern California in September 2016. The workshop which will features speakers such as Buzz Aldrin will be an opportunity to advance the design and be part of the exhibition.

Among the concepts from the 25 finalists are unique projects as “Neurosynthesis,” which includes a closed river system and even an artificial waterfall; “Project Dandelion,” which uses the planet’s soil to provide sustainable oxygen and water; and “The Mars Living Machine,” which explores how extreme environments like Mars will help shape architecture.

“What we’re trying to do in our workshop is to experiment,” project creator and self-proclaimed “Marschitect” Vera Mulyani told Digital Trends. “The gravity on Mars is different, so the density of the building materials will be different. It’s not about an architectural project that just looks cool; we have to see how far we can push 3D printing by experimenting [with] new ingredients for the paste and eventually building in some of the most extreme places on Earth. We want to learn how we can modify what we have today so that we can use it on Mars. Once we have that answer, we can improve our tools.”

The next step will be to 3D Print these concepts and test them in one of the most inhospitable places on earth  most inhospitable places on Earth – the Mojave Desert. 3D printing and additive manufacturing could make colonisation possible because the capacity to fabricate just about anything require in-situ from the few raw materials found on the planet and the few raw materials that could be transported will be essential for a self-sustaining colony. Having raised almost $30,000 on kickstarter to make the Mojave dream a reality it will allow the finalists to begin to replicate the requirements for humans to colonise Mars.

z-2-spacesuit-3d-printed

There are numerous organizations working to get mankind at some point in another twenty years onto the surface of Mars. As important as it will be to find out how exactly to get there, it will likely be equally as important to actually have the ability to place foot without dying on the planet. So, as NASA preps with its Space Launch System and Orion crew ejection seat for a mission to Mars, the space agency is also working on the spacesuit astronauts will be wearing on their excursion to the Red Planet. And, if the new Z-2 prototype spacesuit is really made for that trip, it’ll ideally integrate several cutting edge technologies, including 3D printing and 3D scanning.

The fabric of the suit itself will enable greater mobility, as it will, possibly, be printed from light weight, high-durability composites. Along with enhanced freedom, this material will protect against the harsh environment of Mars. In order to make sure it fit astronauts, the space agency envisions, 3D scanning the crew and, then 3D printing in the depths of space or on the Red Planet itself. 3D printing them on the planet like other space printing suggestions, is also meant to decrease the quantity of cargo space used on the trip as are some other fascinating aspects of the suit’s design. Included in these are water evaporation systems and regenerative carbon dioxide removal for temperature and breathing regulation.

To simplify the process of proceeding to its exterior from the limits of the spacecraft, NASA has proposed a system by which astronauts crawl into the Z-2 landing modules are built into by from the back through a hatch. This removes the need for a conventional airlock, also removing the likelihood of bringing contaminants.
