NASA's 'Real Martians': Inside the plans for a crewed Mars mission

To coincide with the release of 'The Martian,' NASA is showcasing its projects that are gearing up for a human mission to the Red Planet. 

NASA scientists and engineers are hard at work developing the technology that will be necessary for future human missions to Mars.

Are you ready for Mars? NASA is working to get the agency ready for a human mission to the Red Planet in a few decades, and is showcasing its personnel and projects online.

Among NASA's many spotlights is a fascinating new video that zooms in on a NASA power system engineer's quest to create enough electricity to power a Mars base. You can see's full coverage on "The Martian" here.

These are some of the stories of the people working on Mars mission planning, as described

Camille Alleyne, International Space Station Associate Program Scientist

To Alleyne, the International Space Station showcases many different kinds of research, ranging from biology to physics to Earth and space science. One key aspect of it shows how the human body changes when it is in microgravity for months at a time. The space station is also a forum for international partnerships on science management, which will be needed for a mission to Mars.

Al Bowers, Chief Scientist
NASA Armstrong Flight Research Center

One of Bowers' projects is a prototype Martian aircraft called Prandtl-m, or Preliminary Research Aerodynamic Design to Land on Mars. The prototype is designed to be released from a high-altitude balloon to test the airplane's aerodynamic performance at a Martian-like altitude.

Ian Clark, Principal Investigator
Low Density Supersonic Decelerator

This spacecraft prototype features an inflatable decelerator on the capsule, as well as a big, traditional parachute, to slow a spacecraft entering the thin Martian atmosphere. If the system works as planned, it will allow access to elevations on Mars that were not available to spacecraft before. LDSD testing has happened at 200,000 feet above Earth to simulate Mars. Additionally, tests have been run on the ground with a rocket-powered sled — a new tech for NASA.

Brian Day, Project Manager, Solar System Exploration Research Virtual Institute
NASA Ames Research Center

Day is the creator of a Web-based portal called Mars Trek, which gives both mission planners and the general public a high-definition view of the Martian surface. Among other uses, the tool is being deployed to figure out the best site to land the Mars 2020 rover. It also will chart possible locations for future human landing sites.

Jim Green, NASA Planetary Science Division Director

Science fiction is important to Green in helping to understand science, because it shows how people think and how to leverage current knowledge of Mars to support a story. And there have been changes since "The Martian" was written, he points out. There's more humidity in the atmosphere than scientists knew about before the book was written, providing more opportunities to access water. And with the discovery of nitrogen products on Mars, it's possible to produce fertilizer.

Dave Lavery, Program Executive for Solar System Exploration

One of Lavery's projects is to figure out the best way to return a sample of the Martian soil back to Earth. This includes challenges such as how to pick the sample up, wrap it in a protective container and transport it to Earth — using a rocket that launches from another planet with no human involvement. The sample, once returned, could point to hazards for humans on the Martian surface.

Rafael Lugo, Aerospace Engineer
NASA Langley Research Center

Lugo is working on simulating the trajectory for NASA's Space Launch System, a rocket that is supposed to bring astronauts across the solar system. Right now he is trying to figure out where the rocket would go during the first Earth-to-moon mission using SLS, from launch to the spacecraft landing by itself at the end of the mission.

Lee Mason, Power System Engineer
NASA Glenn Research Center

Mason works on power systems for space applications, such as a radioisotope thermoelectric generator that produces electricity through nuclear heat. This generator is in use on Mars for the Curiosity rover, and NASA is working on bigger systems that could generate 40,000 watts. This would be enough to power a Mars base intended for use by six to eight astronauts. [Amazing Mars Photos by NASA's Curiosity Rover]

NASA Astronauts Scott Kelly, Kjell Lindgren and Tracy Caldwell Dyson

Kelly, who is doing a one-year mission on ISS, says his mission is simulating the journey to Mars involving, for example, the performance of the life support system. But there will be key differences, such as the fact that the spacecraft will be in sunlight the entire time. Lindgren says one lesson he learned on his first spaceflight is that the human brain can adapt to many circumstances. And Dyson, an advisor on "The Martian," says the key to success on a long mission is faith, hope and flexibility when you need to go outside the mission plan. 

Ryan Norman, Physicist
NASA Langley Research Center

Norman is part of the space radiation group, which looks at the effects of radiation on vehicles, habitats and most especially the human body. As part of this, the Curiosity rover's Radiation Assessment Detector gives investigators information on the space radiation environment on the surface of Mars.

Jennifer Pruitt, Lead Sustaining Engineer
Marshall Space Flight Center

Pruitt is on the team in charge of the urine processor on the International Space Station, which converts sweat and urine into drinkable water for the astronauts. She also monitors the oxygen generator, which splits water into its hydrogen and oxygen molecules to keep the right amount of oxygen in the air they breathe. Her goal, she says, is to keep the astronauts happy and healthy for long-duration missions — just like a Mars mission would have to do.

Jennifer Stern, Planetary Geochemist
Sample Analysis of Mars

The SAM instrument aboard Curiosity has provided a wealth of information about the atmosphere that we didn't know before. For example, SAM has found nitrates — a biologically and chemically available source of nitrogen that nature uses for life-friendly processes such as building amino acids and nucleobases.

Carly Watts, Technology Development Engineer
Next Generation of Spacesuit Portable Life Support Systems

International Space Station astronauts currently use a 35-year-old spacesuit that was developed for use on the shuttle. While it works well in microgravity, a Mars spacesuit will need to be more flexible, allowing the astronauts to bend over and pick up things. Watts is part of a team that is taking advantage of newer technology created in the past four decades to develop cutting-edge spacesuits and support systems that could protect humans visiting the Red Planet.

What is the Monitor difference? Tackling the tough headlines – with humanity. Listening to sources – with respect. Seeing the story that others are missing by reporting what so often gets overlooked: the values that connect us. That’s Monitor reporting – news that changes how you see the world.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to
