Getting astronauts to Mars will be far from a cakewalk. In order to safely land a crewed ship on the surface of the red planet, the agency needs to invent things that don’t yet exist. And we’re not talking about just one or two or five new gadgets. NASA is working on a staggering 40 new technologies in order to meet a 2033 deadline for launching a crew to Mars that can live on the planet for at least a few months.
Yes, Thomas Edison was awarded thousands of patents, but the man wasn’t trying to get human beings to safely land on the surface of another world sitting 33.8 million miles away, separated by a cold, eternal vacuum. Each of those 40 technologies is a hell of a lot more complex than a light bulb.

Stephen Jurczyk, the associate administrator of NASA’s Space Technology Mission Directorate, is the person in charge of making sure NASA’s engineers stay on task and get these technologies ready on time. He seems optimistic NASA can pull off a trip to Mars, but he says the agency just needs to remain flexible while moving forward. “This is a tremendous challenge, and we absolutely can do this,” he tells Inverse.

Elon Musk’s vision of Mars colonization has us living under geodesic domes made of carbon fiber and glass. But, according to a study recently published in the journal Scientific Reports, those domes may end up being made of brick, pressed from the Martian soil itself.

A team of NASA-funded researchers from UC San Diego, and led by structural engineer Yu Qiao, made the surprising discovery using simulated Martian soil — that’s dirt from Earth which has nearly the same physical and chemical properties. They found that by compressing the simulant under high pressure, it readily created blocks stronger than steel-reinforced concrete.

This isn’t the first time that researchers have attempted to create building materials from native resources on alien worlds. Last year, a team from Northwestern University figured out that you could create concrete by mixing Martian soil with molten sulphur. Qi’s own team had previously sought to make bricks from lunar soil material, managing to reduce the amount of binder needed from 15 percent of the final weight to just 3 percent, before turning their attention to the red stuff.

Scientists Hatch Wild Plan to Terraform a Region of Mars

A research team has devised a plan to make a portion of Mars more Earth-like by slamming an asteroid into it.

This Mars Terraformer Transfer (MATT) concept would create a persistent lake on the Red Planet’s surface in 2036, potentially accelerating Mars exploration, settlement and commercial development, the team said.

“Terraformation need not engineer an entire planetary surface. A city-region is adequate for inhabitation. MATT hits this mark,” the Lake Matthew Team, the group behind the idea, wrote in a press release last month.

Key to the plan is a “Shepherd” satellite, which would steer an asteroid or other small celestial body into the Red Planet. That impactor would inject heat into the Martian bedrock, producing meltwater for a lake that would persist for thousands of years within the warmed impact zone, Lake Matthew Team members wrote.

One of the many challenges of colonizing Mars is that the planet is lacking many of the natural resources we rely on here on Earth. We’ll need to bring as much of what we need to survive as possible, but you can only pack so much into a spaceship. So scientists are developing ways to utilize at least one of the red planet’s most abundant resources: dust.

We’ve had a hard time coming up with reasons as to why everyone needs a 3D printer here on Earth, but on Mars the machines could be used to manufacture tools, spare parts, even entire structures, habitats, and vehicles, given there’s no hardware stores for astronauts to visit if we eventually send humans on the 34 million mile journey. But 3D printers don’t make things out of thin air.

You’ve probably seen an affordable consumer-friendly 3D printer at work, melting and extruding thin lengths of plastic to build up a model. There’s no plastic on Mars, however, and packing miles of filament on a ship takes up valuable space that could be better used for transporting oxygen, water, and other essentials. So scientists at Northwestern University’s McCormick School of Engineering have developed a way to turn extraterrestrial materials, like Lunar and Martian dust, into a 3D printing material.

Two young Cupertino residents have been recognized for truly out-of-this world science projects.

Lauren Lee, 12, has been selected as a junior division winner of the “Mars Medical Challenge” sponsored by the American Society of Mechanical Engineers Foundation with technical support from NASA. Ansel Austin, 14, was selected as one of four finalists in the challenge’s teen division.

The challenge tasked youngsters nationwide with creating a digital model of a medical or dental device that is entirely 3-D printable and can be used by astronauts on a three-year round trip to Mars.

Lauren, a seventh-grader at Kennedy Middle School, created a drug delivery device, with inspiration from a family member.

Ansel, a freshman at Valley Christian, created the wearable “Flex Brace,” to protect astronauts’ bones.

The first explorers on Mars will need a new kind of spacesuit, and a university-based team has taken a novel approach to design the equipment.

Researchers have set up a “collaboratory” at the University of California, Berkeley, to come up with a spacesuit that will allow expeditionary crews to work effectively on Mars.

“The kind of suit that we’re talking about is a blue-collar suit. You’ve got to be able to be out and about on Mars 7 to 8 hours a day, seven days a week,” said project leader Lawrence Kuznetz, a UC Berkeley professor and former NASA engineer with a long history of investigating Mars spacesuit concepts.

About 50 Berkeley students are now taking part in this MarsSuit Project, via a design class that began in mid-January. That core group, Kuznetz said, is one slice of a larger, interactive talent pool that includes the University of Helsinki, Texas A&M University, the Massachusetts Institute of Technology, and students at the Technical University of Ljubljana in Slovenia and at other institutions, along with several NASA centers, nonprofits and private organizations, such as Paragon Space Development Corporation in Tucson, Arizona.

Teams have been established to delve into everything from hardware, soft goods and software to boots, gloves, thermal control and waste management.

“The long-range vision is to have this course semester after semester,” Kuznetz said, “with each semester building upon the work of the prior semester … all intent on maturing the MarsSuit design.”

Simulated Mars dust makes for weird 3D-printed objects

When humans finally get to Mars, they’ll need to use local resources in their quest for survival. Mars has a lot of dust, and the European Space Agency is looking at how to transform it into useful 3D-printed objects. On Wednesday, the ESA posted the fascinating results of a 3D-printing test using simulated Mars soil on Wednesday.

The team 3D-printed an igloo-like structure and a wall corner. They’re sized for a small mouse, but they show that it’s possible to create sturdy objects using the local resources on Mars.

The researchers used a Mars soil simulant called JSC-Mars-1A, which contains volcanic material, mixed with phosphoric acid as a binder. The mixture was extruded through a nozzle and layered in typical 3D-printing fashion.

The igloo and corner won’t win many points for aesthetics, but that’s OK.

Colonizing Mars will be no easy feat. It will require billions of dollars and years of specialized research led by some of the smartest scientists and engineers in the world. It will demand advanced technologies, yet to be invented — new kinds of spacecraft, for example, advanced rocket propulsion, deep-space life-support systems and high-speed communications.

But when humans arrive at the Red Planet, their best chances for success and survival will depend on simple materials, low-tech solutions and a broad set of problem-solving skills that will allow people to adapt.

“Here on the Earth, when we go to a remote location to do an engineering development project, we’ve learned that taking high-tech equipment isn’t really the right approach. What you want is appropriate technology,” said planetary scientist Phil Metzger, who is also a co-founder of NASA Kennedy Space Center’s Swamp Works. “You want technology to be maintained using the local resources and local labor.”

Want to Live on Mars? We have the ice house for you. NASA is crowd-sourcing ideas for future Martian habitats and the leading design is essentially a modified igloo. That’s right, the first humans to inhabit Mars, may reside in homes made of ice.

Last month, a research team from the University of Texas announced that Mars is hiding a secret supply of water just below its surface. They reported that a region on Mars known as Utopia Planitia is harboring as much water as Lake Superior here on Earth — only difference is the Martian reserves are frozen solid.

The ice reservoir is located a mid-northern latitudes — which means it’s about halfway between the equator and the poles — and is reportedly the size of New Mexico. Even though the supply may be buried under a layer of regolith ranging from 3 to 33 feet deep, this finding is still excellent news for a group at NASA’s Langley Engineering Design Studio in Hampton, Virginia.

New Paper Explores Cryptocurrency for Space Colonies

Blockchains in space?

According to one research paper published by an Indian government official, the idea isn’t so far-fetched.

Dr Kartik Hegadekatti of India’s Ministry of Railways posits in a new paper, entitled “Extra-Terrestrial Applications of blockchains and Cryptocurrencies”, that the tech could provide the basis for a space-based money in lieu of paper money or physical coins. Hegadekatti works for the ministry’s Commercial Department.

Hegadekatti has written about cryptocurrencies in the past, exploring how a ‘NationCoin’ could be issued by a country in a paper from August. The paper’s timing is notable, given India’s controversial push away from paper currency and a rise in bitcoin purchase activity in the country.

Though the concept sounds a bit far-fetched and entirely speculative – humans have only set foot on the Moon a handful of times, and to date no manned mission has been launched to Mars – Hegadekatti argues that launching paper or coin-based monies into space is impractical given their cost and weight.
