... matter where we go in the solar system, we would need to build habitats for growing plants. These habitats would protect the plants from the cold, radiation and lack of a suitable atmosphere, and we could use the regoliths as a substrate for growing the plants. Because there are nutrients in these regoliths, we would ...

Humans are not adapted to space. The natural space environment would kill a human due to the lack of pressure, atmosphere, heat, and the exposure to ...

Many of the plant production systems designed for space habitats have the plant seed set inside a fabric-like material that is attached to the hydroponic system. As the roots grow through the fabric they attach to the fabric and hold the plant firmly ...

... are safe and that last for many years in space. We learn about living in space every time we go there. We are inventing better technology and smarter computers which will allow us ... larger numbers of people. As the habitats get bigger they will have more and more plants. The plants will clean the oxygen and will provide more oxygen as well as food. ---- Answer ...

... the technique of growing plants without soil, usually in water with all the nutrients dissolved into it. However, if we were building a habitat on Mars, we would grow the plants in the Martian regoliths, inside growth chambers. In a space station, we would need to choose a hydroponic system that would keep the ...

... missions are the real challenge. The largest issue we will contend with is not how to carry water with us through space, but rather, how to move enough water up from the Earth's surface to support a long-duration mission. Because of the expense of lifting high quantities of water up to orbit, we have ... to capture small dormant comets, place them in Earth orbit and mine them for ice. We are not yet technologically advanced enough to undertake missions of this nature. Mining ice from ...

... space. We do have some instructions on what to do if we ever hear an alien radio signal. These instructions include who to contact, how to verify the signal and what we should do initially. Not surprisingly, we would not answer them ... . The spaceships Voyagers and Pioneers carry special disks that show pictures of humans and where we come from—Earth. The disks also carry greetings in over a hundred different languages ...

Magnetic board games, like the ones you would take with you on a long car trip, would work the same way in space. Magnets and Velcro can both be used to keep the pieces from floating away. Games that use dice wouldn't work because the dice would never stop rolling ---- Answer provided by US Space and Rocket Center Image:K2S logosmall.jpg ...

... likely travel to low Earth orbit (LEO) with a chemical rocket. Once in orbit we would either dock with a space station and transfer to an outbound vehicle headed to EML- ... station and EML-1 would take about a week—the same length of time it used to take aircraft to travel across the Pacific Ocean—but we could go anywhere on the Moon. Traveling from a LEO orbit to a LLO with a TLI and then down to the Moon's surface would take about ...

The Shuttle has several water tanks, from which we can get water for drinking, for re-hydrating our dried food, and for washing. Also, ... . Fortunately, very clean water is a by-product of this reaction, and we can add this water to the supply we launch within our water tanks. ---- Answer provided by Charles Camarda, Ph ...
