All told, Von Braun calculated the size and weight of each ship, how much fuel each of them would require for the round trip and even computed the length of rocket burns necessary to perform the required maneuvers. As the next logical step beyond crewed missions to the Moon the Apollo Program , it was only natural to assess what a mission like that would entail, and whether or not it would be technically feasible. From to , two proposals were made that could have made crewed missions to Mars possible. The first was Project Orion , which proposed a nuclear pulse propulsion NPP spacecraft that would have nuclear warheads propel itself to other planets and even other star systems within a relatively short space of time.
Such a mission, which would have been able to carry much heavier payloads, would have made missions to Mars feasible. However, the Limited Test Ban Treaty of forbade the use of nuclear warheads in space and the project was abandoned. These studies were the first to make use of actual NASA spaceflights and indicated that such a mission could be done using eight Saturn V boosters, or an upgraded rocket.
These studies laid the groundwork for further theoretical work on the subject. In the s, following the success of the Apollo Program , Von Braun advocated for a crewed mission to Mars by the s. The missions would rely on a Saturn V rockets with a nuclear-powered upper stage. This proposal was considered by President Nixon but passed over in favor of the Space Shuttle Program. In , aerospace engineers Robert Zubrin and David Baker wrote a research paper titled " Mars Direct", in which they made proposals for a cost-effective plan to send a mission to Mars using current technology.
In the book, Zubrin paints a picture of a series of regular Martian missions that ultimately coalesce into colonization efforts. This would begin with astronauts leaving habitation modules on the surface for future crews to use. The construction of large subsurface habitats would follow, where people would have natural radiation shielding. Over time, hard plastic geodesic domes that are radiation-resistant and abrasion-resistant would be deployed to the surface to create larger modules and indoor crops.
Local industries would also begin to use indigenous resources to manufacture plastics, ceramics, and glass. These industries and commercial opportunities will draw settlers, workers, and investment to Mars. For the first few generations, Zubrin indicated that the colony will still be largely dependent on Earth for supplies. But eventually, a Martian settlement would be able to become profitable because of its large caches of precious metals and the fact that concentrations of deuterium are five times higher on Mars than Earth, which can be converted into hydrogen and liquid oxygen fuel.
Between and , a series of studies were conducted in which Soviet rocket pioneer Mikhail Tikhonravov recommended taking the necessary steps for making a crewed Mars expedition. This included the creation of a Martian Piloted Complex MPK and using the then-proposed N1 rocket - a heavy-launch vehicle designed to send Soviet cosmonauts to the Moon.
Neither project succeeded because the N-1 rocket was never flown successfully. By the turn of the century, NASA and other space agencies began to seriously contemplate taking the "next great leap". While this would involve conducting renewed missions to the lunar surface, the Moon was seen as a stepping stone at this point. To quote famed Apollo astronaut Buzz Aldrin , the second man to walk on the Moon and a major proponent for Mars exploration:. In my view, U. National Space Policy that was issued that same year. The plan called for three phases and a total of 32 SLS launches between and the s to send all the necessary components to cis-lunar space and near-Mars space before sending a crewed mission to the surface.
It also involved the continued utilization of the International Space Station until to test deep space technologies and study the effects that long-duration space travel and the increased exposure to solar and cosmic radiation that results have on the human body. This uncrewed mission will see the Orion capsule being launched by the SLS for the first time and sending it on a journey around the Moon.

Exploration Mission-2 EM-2 , scheduled for June of , will be the first crewed mission of the Orion, and will similarly involve the spacecraft flying around the Moon. By , Exploration Mission-3 will involve a crewed Orion flying to the Moon to deliver the first of several pieces of the Lunar Orbital Platform-Gateway LOP-G — the next big piece of the overall mission architecture. The station is scheduled to be complete by the mids and is intrinsic to NASA's plan to conduct renewed lunar exploration, as well as long-duration missions to Mars and other locations. The DST will then be used to transport the necessary components to Mars so the final piece of the mission architecture can be built: the Mars Base Camp and Lander , both of which are being developed by Lockheed Martin.
The station will have all the necessary amenities for a four-person crew and will include a laboratory module for conducting key science operations on the Martian surface. The crews will also rely on the reusable Martian Lander to make trips to and from the surface. Once complete, this infrastructure will allow for repeated missions to Mars, which will go beyond NASA and include international and commercial partners. The plan was well summarized by Buzz Aldrin :. To get under way, the International Space Station can serve as a test bed for long-duration life support and for technologies that can safely, reliably and routinely transport crews to the distant shores of Mars.
The ESA also has long-term plans for Mars, though they have yet to build a crewed spacecraft. However, between and , the ESA cooperated with Roscosmos to conduct the Mars Study , a series of cooperative isolation experiments meant to simulate a long-duration mission to Mars. In addition, the ESA has indicated in the past that it hopes to send astronauts to Mars by the mids. This would take place after crewed lunar missions are conducted and the ESA completes a number of robotic missions to the Martian surface.
The proposed Ariane 5 heavy rocket would be the likely candidate for the launch vehicle. This three-phase lunar exploration program, which has sent several orbiters, landers, and rovers to the surface, will culminate with a sample return mission. Once this is done, the CNSA hopes to send Chinese astronauts "taikonauts" to the lunar surface and possibly collaborate with agencies like the ESA to build a lunar base.

So far, all plans for a mission to Mars have been somewhat ambiguous, with robotic missions expected to take place between and the early s followed by crewed missions between and Similarly, the Russians have stated that they hope to conduct crewed lunar missions in the coming decades and put off missions to Mars until mid-century. In , first deputy Nikolay Panichkin of the Central Research Institute of Machine Building - an institute of Roscosmos — indicated that crewed lunar missions were expected by the s, with an expedition to Mars happening in or In April , the head of Roskosmos, Vladimir Popovkin, said that the agency's latest conceptual designs envisioned sending a tonne expeditionary complex to Mars.
This plan would involve the creation of a small fleet of partly-reusable super-heavy launch vehicles that would deliver the components to orbit. Russia has also been pursuing nuclear-electric propulsion concepts since , which would enable long-duration missions to Mars and beyond. These would have the payload capacity to transport heavy components, like the habitat modules envisioned by Popovkin. Aside from federal space agencies, a number of aerospace companies have also drafted plans for colonizing the Red Planet.
This is in keeping with the age of New Space, where private industry is assuming a greater role than ever before and space exploration itself is becoming commercialized. In , a group of Dutch entrepreneurs revealed plans for a crowdfunded campaign to establish a human Mars base, beginning in Known as MarsOne , the plan called for a series of one-way missions to establish a permanent and expanding colony on Mars, which would be financed with the help of media participation. Base powered by 3, square meters of solar panels and the SpaceX Falcon 9 Heavy rocket would be used to launch the hardware.
The first crew of 4 astronauts was scheduled to land in , followed by an addition 4 crew members every two years. Unfortunately, insolvency issues caused MarsOne to declare bankruptcy in Elon Musk has been upfront about his long-term plans to establish a colony on Mars for many years. And while the development of reusable rockets and the Dragon crew capsule were stepping stones to this goal, it is recent developments with the Starship and Super-Heavy completely reusable launch system that SpaceX's Mars missions have truly begun to take shape. Currently, SpaceX is hoping to commence cargo missions using the Starship and Super Heavy as early as , followed by the first crewed flight in According to recent statements by Musk, he hopes to create a permanent outpost Mars Base Alpha by Virgin CEO Richard Branson has long been known for his efforts to create a viable aerospace industry.
But looking ahead, he has also expressed interest in creating a tourist venture that would take customers to Mars. I think its absolutely realistic. It will happen. I think over the next 20 years, we will take literally hundreds of thousands of people to space and that will give us the financial resources to do even bigger things.
The challenges posed by the distance between Mars and Earth and the natural hazards of the planet have led to some creative suggestions. In particular are ideas for Martian habitats that will offer protection against the environment and the radiation, and which can be built using local resources - a process known as in-situ resource utilization ISRU. In the end, any habitat on Mars will have to meet a long list of requirements. Every habitat will also need an airlock to ensure the internal atmosphere is contained, and pressure suits to allow the inhabitants to reconnoiter outside.
This will mean plenty of internal heating, which could be provided using solar heating units, thick insulating walls, and warm clothing. Protection against radiation is also a must and will require either lead-lining, depleted uranium, or some other shielding material on the exterior of the habitat. Otherwise, settlements will have to be built beneath the surface, taking advantage of the natural shielding the regolith provides. Time outside will also have to be limited, and Martian settlers will have to monitor their radiation levels routinely and most likely take anti-radiation meds.
Aside from relying on technology and construction methods to see to our needs on Mars, the geography could also be used as a defensive measure. As scientists have noted many times, there are multiple locations on Mars that would make for good base sites because they provide natural shielding, will be easier to pressurize, have access to water, or are naturally warmer. For example, like Earth and the Moon, Mars has a number of stable lava tubes that are the result of past volcanic activity.
In the region of Arsia Mons, which is near the raised region known as the Tharsis Bulge, multiple "skylights" have been observed that are indicative of underground lava tubes.
