OTTAWA, CANADA – Humans would spend more than a year orbiting and bouncing on the Martian moon Phobos under a mission concept developed by students at the International Space University.
The very theoretical MARS-X mission — presented more as a concept than a firm plan — would see technology development taking place from 2018 to 2022, with communications satellites and rovers winging their way to the planet to be used by astronauts.
In 2023 to 2024, the spacecraft would be built in low-Earth orbit, requiring several launches to accomplish the massive task. Astronauts would then depart in 2024, spending eight months in transit before arriving at Phobos. There, the mission would last 495 days, and the astronauts would take five months to get home.
While NASA and Lockheed Martin helped sponsor the students who created the plan as part of their academic work, the concept itself is not yet funded beyond the students’ initial development.

But Piotr Murzionak, a member of the ISU team, said the proposal is one way that could help fuel interest in space exploration, if it was to be executed..
“It paves the way to Mars. It will be the initial step towards the landing mission on the Martian surface, but without the extra risk involved in order to land directly to Mars,” Murzionak said.
The Mars Exploration Vehicle (as the crew vehicle would be called) would use nuclear propulsion and liquid hydrogen to bring two habitats along with it. One of those would (along with several fuel tanks) be used on Phobos for up to 40 days of surface operations.
It would travel during solar maximum in 2024 to reduce the effects of cosmic radiation from outside the solar system, since the sun’s activity would blow the radiation further away. Further, the crew would be protected from solar flares with high-density polyethylene, as well as a temporary solar storm protection chamber lined with 50 centimeters of water.
The habitat would be spun at 4.4 revolutions per minute, with a habitat of 0.38 to 0.53 the force of gravity — about equivalent to what is on Mars. (This would take 2.5 metric tonnes of fuel to do.)
The students estimate this would cost about $20 billion, but it could go to at least double this due to factors such as “the volatility of political systems and the large amount of bureaucracy involved in any such endeavor,” they write in their final report, which is available here.
Murzionak presented the mission concept at the Canadian Space Society annual conference today (Nov. 14) in Ottawa, Canada.

That is a project I can relate to. Not a simple asteroid mission near Earth in blackness of space where no one can point a finger to to show to their kids that there are the astronauts.
Now that’s a clever reuse of fuel tanks
Is it really possible to recycle 100 % of the oxygen in the life support system (as indicated in the graphic)? I imagine that a really high percentage could be achieved, but everything?
How does the oxygen recycling work, anyway?
Nice, they used Kerbal Space Program to make that video.
