NASA has unveiled designs for 3D-printed* towers that could shelter the first humans on Mars.
Each of the striking structures include living spaces as well as a science laboratory for experiments.
And the designs could be useful sooner than we all hoped, with a re-examination of information from 2013 from the Mars Express orbiter showing it recorded a burp of methane gas coming from Mars.
Methane is a promising sign of the possibility of life because of its links to biological* activity on Earth.
The Mars tower houses were designed by the winners of NASA’s 3D-Printed Habitat* Challenge.
The competition tasked teams to submit designs for a habitat that could one day house the first astronauts on Mars.
First place was taken by a team called ‘SEArch+/Apis Cor’, from New York, US.
Their twisted, tower-like ‘Mars X House’ — which exists only as digital drawings for now — can be upgraded with 3D-printed add-ons.
The team’s plan involves multiple Mars X Houses being built on Mars by AI*-powered robots before humans arrive to live in them.
“Mars X House is autonomously* constructed using indigenous* Martian materials,” NASA said in a video about the designs.
“It forms a pioneering and durable* habitat supporting future human missions to Mars.”
Astronauts would both live and work in the complex, which lets natural light filter in through holes dotted around the walls.
Models of the structures show astronauts working in the lab and relaxing in their rooms, with one astronaut even playing a guitar for a bit of relaxation.
Mars X House was one of three winners of Nasa’s Habitat Challenge.
Second place went to Team Zoperhous from Arkansas, US, whose shelter would be printed by an autonomous rover.
The Mars Incubator group from Connecticut, US, came third with a design that includes space to grow plants for food.
The three winners shared a $139,000 prize ahead of the grand final next month, for which they will build a 3D model of their designs for the chance to win the $1.1 million prize.
MARS’ MYSTERY METHANE BURP
NASA’s Curiosity rover detected a tiny amount of methane in 2013 but where the gas was coming from was never explained.
Scientists at the National Institute of Astrophysics* in Rome, Italy, have looked afresh at the information that came back from the Mars Express orbiter, also in 2013. They found the spacecraft also detected a methane “burp” just one day after Curiosity.
Having the same information coming in from two separate spacecrafts means it is more likely to be true.
The best guess for the source of the gas is that it escaped from cracks in ice near the Gale Crater, which is thought to be an ancient lake.
Methane is a gas made of carbon* and hydrogen*. On Earth, it is found below the ground and the sea and in the atmosphere. Some, but not all, of the methane on Earth is from living things breaking down, which is why scientists are excited about the possibility that methane on Mars could be a sign of current or former life.
Computer models have shown that up to 4000 tonnes of methane may have been released.
The ExoMars Trace Gas Orbiter will be the next spacecraft to look for Mars methane and scientists will be investigating the carbon in the gas to see if it actually is a sign of life.
- 3D printed: a structure made in layers by a computer
- biological: relating to living things
- habitat: the environment where something lives
- AI: artificial intelligence; robots that can do things normally needing human intelligence
- autonomously: with the freedom to act independently, rather than by remote control
- indigenous: from that place
- durable: lasts well
- astrophysics: study of the physics of stars and space
- carbon: non-metal pure substance that is a part of all living things
- hydrogen: a pure substance; there is more hydrogen than any other substance in the Universe
- Who or what would build the Mars X houses?
- Would astronauts living in Mars X housing get any sunlight?
- Which two spacecraft detected methane on Mars?
- Where do the scientists think the methane came from?
- How much methane do the scientists think was released?
