What Technology Is Needed?
Surprisingly, nothing revolutionary, and nothing we haven't seen before. What makes Mars One so convenient is that we can use current components to build every stage of the mission. The landing module will use current technology. There's no need for a heavy-duty launch vehicle or rovers. The trip will only take 210 days, so water recycling is not required.
With that said, here's some of the technology you might see on the future mission:
The SpaceX Rocket Engine
The private aerospace manufacturer is currently developing an engine that will be used on the Mars rockets. It's called the Raptor, and according to CEO Elon Musk, it can put out 510,000 pounds of thrust at sea level.
While Musk readily admits that the engine is still "weak" compared to NASA engines, he insisted that the company is in a good spot during the testing. Several of these engines will be installed on the shuttle that will take humans to Mars — as early as 2024, the company claims. So far, the only major news on the engines is the fact that they've been delivered to the SpaceX test sites. Hopefully more news will surface in the coming months.
Ah, the sun — it's always burning bright, even behind dark and scary storms. It's one of the best resources out there because it's powerful, plentiful and dependable. We harness the sun's energy by using solar panels.
This technology is the best choice for powering Mars One. The settlement will set aside 3,000 square meters of surface area for the panels. They are thinner than the ones here on Earth, which makes them a bit less efficient. But what they lack in efficiency they make up in portability. They’re also extremely light.
But what if solar panels weren't an option? Mars One would have to resort to a nuclear reactor, which would take an enormous amount of time and money to create. Plus, it's extremely risky for something way out in space.
The Permanent Settlement
The main purpose of the Mars One mission is to send a crew to permanently settle on the planet. There will be no return missions. There are several reasons that make this the most convenient and feasible option:
- A return vehicle, its propellant and the systems needed to produce the propellant are not required.
- Technology that would allow rockets to take off from Mars and come back to Earth doesn't exist yet.
- If there was a return mission, it would need to be tested with several unmanned vehicles before any astronauts would be included.
- The first rocket to blast off from Mars carrying a crew would also carry several risks.
- Astronauts would have to adjust to Earth's gravity again after spending nearly two years in a zero gravity environment.
A Landing Module
In order to touch down on the surface of the Red Planet safely, the Mars One astronauts will need a landing module. And in order to ensure maximum safety, the lander will be tested eight times before the Mars One crew uses one to reach the planet.
All mechanical and electrical components included on the lander will be simple and durable in case any of the crewmembers need to repair them after landing. Essential and precise designs in the lander's circuitry will make sure thermal management and high-frequency RF components function properly.
