PIX4640020: Base sur Mars - Illustration - Mars Ice Home concept - Artist's view of an inhabited base on Mars. Inflatable housing concept surrounded by a layer of ice. The “” Mars Ice Home”” is a large inflatable torus, a shape similar to an inner tube, that is surrounded by a shell of water ice. The Mars Ice Home design has several advantages that make it an appealing concept. It is lightweight and can be transported and deployed with simple robotics, then filled with water before the crew arrives. It incorporates materials extracted from Mars, and because water in the Ice Home could potentially be converted to rocket fuel for the Mars Ascent Vehicle, the structure itself doubles as a storage tank that can be refilled for the next crew. Another critical benefit is that water, a hydrogen-rich material, is an excellent shielding material for galactic cosmic rays - and many areas of Mars have abundant water ice just below the surface. Galactic cosmic rays are one of the biggest risks of long stays on Mars. This high-energy radiation can pass right through the skin, damaging cells or DNA along the way that can mean an increased risk for cancer later in life or, at its worst, acute radiation sickness / Bridgeman Images
PIX4640078: Experience Mars500 - Mars500 experiment facility in Moscow - Installed at the Russian Institute of Bio-Medical Problems (IBMP) in Moscow, the 550 m Seal Simulator consists of an interplanetary spacecraft and a Martian lander, and features a Martian landscape. The Mars500 experience is a Martian mission simulation that began on June 3, 2010. The crew locked up for 520 days consists of six people. They are Italian-Colombian Diego Urbina (27) and Frenchman Roman Charles (31) selected by ESA, Russian Sukhrob Kamolov (32), Alexey Sitev (38), Alexandr Smoleevskiy (33) and Chinese Wang Yue (26). March 500, the first full-length simulated mission to Mars, started on June 3 2010 when the six-man crew entered their 'spacecraft' and the hatch was closed. The experiment will run until November 2011. Diego Urbina and Romain Charles from Europe, Sukhrob Kamolov, Alexey Sitev, Alexandr Smoleevskiy and Wang Yue from China face a mission that is as close as possible to a real space voyage without leaving the ground. During 520 days, they will live and work like astronauts, eat special food and exercise in the same way as crews aboard the International Space Station / Bridgeman Images

PIX4641303: ISS and inflatable module - Large habitat and ISS: Artist's view of a large inflatable module (much larger than all existing modules) installed on the International Space Station (ISS). A live module or CEV (Crew Exploration Vehicle) type Orion prepares to moor to the inflatable module. A manned Crew Exploration Vehicle (CEV) prepares to dock with a spacious inflatable habitat attached to the International Space Station (ISS) at an altitude of 250 nautical miles. This inflatable habitat, much larger than any existing ISS module, is a combination of layers of flexible material capped by sturdy docking hardware at either end. The inflatable portion is collapsed and sandwiched between the docking hardware portions for launch from earth and then inflated and pressurized with a breathable atmosphere once in orbit. The habitat features a pair of 42 x 24 inch windows to the outside. The habitat is attached to a pressurized module of the ISS via a Common Berthing Mechanism (CBM) while the other end of the habitat features an International Docking System Standard (IDSS) system for docking with manned spacecraft. The inflatable portion of the habitat is 45 feet long with a maximum diameter of 28 feet. Including docking hardware the total length is 55 feet. The interior of the habit, sans storage and other equipment, provides approximately 17 thousand cubic feet of micro gravity living space. The CEV is 33 feet long with a maximum diameter of 20 feet while the solar voltaic panels have a maximum spread of a little over 60 feet / Bridgeman Images

PIX4640224: Space lift on the Moon - Artist's view - Lunar elevator lunar base - Lunar base equipped with a space lift. A manned lunar space elevator prepares to depart from its manned lunar base. Surrounding it are support facilities and cargo. The yellow machine on the right is an articulated manned manipulator for handling cargo and managing the elevator. The space elevator concept involves running a cable from the surface of a planet or moon up to a gravitationally - stable point in space, whereupon a specially - designed vehicle can climb and descend the cable. Also known as tether propulsion and non-rocket space launch, this method permits an alternative way to access space. In the case of the lunar space elevator, the cable is anchored to the surface of the Moon and ascends to a stable Lagrange point. In this illustration the cable, in the form of a ribbon, is anchored to the southern hemisphere of the near - side of the Moon and ascends approximately 35,000 miles towards the Earth. The manned climbing vehicle, the “” elevator,””” is powered by solar energy collected via its array of photovoltaics. The manned elevator illustrated is approximately 160 feet long. Traveling at a velocity of roughly 60 mph it would take the elevator about 3 weeks to cover the distance between the lunar surface and Lagrange point in space / Bridgeman Images
