But how real is itYour First Second Amp Well you know its gonna be alright. John Lennon Its alright. Chris Stamey Its alright its alright its. How a 29yearold idealist built a global drug bazaar and became a murderous kingpin. Nasa says its serious about one day doing a manned mission while private companies are jockeying to presentever more audacious plans to get there. And equally important, public enthusiasm for the Red Planet is riding high after the Curiosity rovers spectacular landing and photo rich mission. Earlier this month, scientists, Nasa officials, private space company representatives and other members of the spaceflight community gathered in Washington D. C. for three days to discuss all the challenges at the Humans to Mars H2. M conference, hosted by the spaceflight advocacy group Explore Mars, which has called for a mission that would send astronauts in the 2. But the Martian dust devil is in the details, and there is still one big problem We currently lack the technology to get people to Mars and back. An interplanetary mission of that scale would likely be one of the most expensive and difficult engineering challenges of the 2. Mars is pretty far away, Nasas director of the International Space Station, Sam Scimemi said during the H2. M conference. Its six orders of magnitude further than the space station. We would need to develop new ways to live away from the Earth and thats never been done before. Ever. There are some pretty serious gaps in our abilities, including the fact that we cant properly store the necessary fuel long enough for a Mars trip, we dont yet have a vehicle capable of landing people on the Martian surface, and we arent entirely sure what it will take to keep them alive once there. A large part of the H2. M summit involved panelists discussing the various obstacles to a manned Mars mission. Ive said repeatedly Ill know when were serious about sending humans to the Mars surface when they start making significant technology investments in particular areas, engineer Bobby Braun, former Nasa chief technologist, told Wired. The good news is that theres nothing technologically impossible about a manned Mars mission. Its just a matter of deciding its a priority and putting the time and money into developing the necessary tools. Right now Nasa, other space agencies, and private companies are working to bring Mars in reach. Here, Wired. com presents the most challenging obstacles well have to overcome to get to Mars and how to fix them. Getting off the Earth. Before you can run you need to walk. And before you can do deep space exploration, you need to get off your own planet. While weve been sending people and probes into space for more than 5. Mars mission would be on a much larger scale than almost anything weve done before. There is no rocket in existence that can take off from the Earths surface and escape its gravitational pull to reach space carrying the weight of a large spacecraft, astronauts and all the supplies and materials needed to get to Mars. Most likely, rockets would have to make several trips to drop off supplies and pieces for a vehicle into low Earth orbit. There astronauts would slowly build the vehicle over time and then rocket off to the Red Planet. That still requires some heavy lifting. The largest construct assembled in space, the International Space Station, has a mass of 4,5. According to Nasa, a Mars vehicle capable of taking people to the Red Planet and back would be smaller than the space station around 1,2. But our capabilities are hampered by the retirement of the Space Shuttle fleet, which was capable of carrying large masses to Earth orbit with relative ease. Using existing rockets, aerospace engineer Bret Drake, who leads planning and analysis at Nasas Exploration Missions and Systems Office, estimated it would take 7. Mars mission spacecraft. Considering the ISS took more than a decade to complete, assembling a Mars vehicle would require a very long time. But in the future, this task should be much easier. Nasa is hoping to have its Space Launch System ready by 2. Saturn V that carried astronauts to the moon. The private spaceflight company Space. X is also working on its new Falcon Heavy launch vehicle, which would have somewhat less cargo capacity than Nasas big rocket but still much greater than anything around today. Falcon Heavys first tests could begin later this year. Wifi Hotspot Driver For Windows 7. Nasa estimates it would need to fire at least seven of its new SLS rockets to deliver to orbit the people, supplies, and ships necessary for a Mars mission. And while SLS could help get to the Red Planet, it should be noted that there are other alternatives we could pursue. Fuel storage. Humans arent the only things you want to send on a manned Mars mission. In order to stay alive in space, people need lots of things food, oxygen, shelter, and, perhaps most importantly, fuel. Somewhere around 8. Mars mission is going to be propellant. Trouble is, storing that amount of fuel in space is hard. Objects in low Earth orbit the place youd park your Mars spaceship while you built it travel around the world every 9. During half that time, they experience the intense heat of the sun and then the unheated blackness of space. That difference causes liquid hydrogen and oxygen rocket fuel to vaporise. Unless tanks are regularly vented, containers holding these materials are liable to explode. Hydrogen in particular is susceptible to leaking out of its tanks, resulting in a loss of about 4 percent per month. This means that if a Mars mission required a year to assemble in low Earth orbit, it would lose more than half of its propellant before even departing to the Red Planet. At a cost of around 1. Nasa is actively pursuing new technology that would allow them to store propellant in space for long periods of time. Starting this year, the agency hopes to demonstrate the capability for large, in space cryogenic loading and transfer. Such technology would be extremely valuable for a manned Mars mission and could one day lead to the equivalent of a Space Age gas depots waiting to top up a rockets fuel. Advanced propulsion. While you want to get people to Mars as fast as possible to minimise exposure to the hazards of radiation and weightlessness in space, their supplies can leave Earth earlier and travel at a more leisurely pace. A relatively low power engine could push along a large ship carrying astronauts supplies for their time on Mars. In its interplanetary plans, Nasa would like to send such things on ahead of a crew and have them waiting on the Martian surface when the people arrive. The agency is currently working on advancing solar electric propulsion, which shoots ionised gas behind a craft to move it forward. Previous missions, such as Nasas Dawn and the Japanese Hayabusa spacecraft, have used this method. A Mars mission would need much larger solar electric thrusters than have been used before. The agency currently has plans for a mission to collect a small asteroid and tug it back to Earth, which could be helpful in moving this technology forward. Landing on Mars. We currently dont have the capability to land people on Mars, plain and simple. This is a fairly recently recognised problem, having only been understood through calculations made in the early 2.
