Did a poor person in Rome have a fresh water supply?
Yes, the poor in Rome had a fresh water supply. There were numerous fountains all over the city where water was free for the taking.
Where is located over 90 percent of world's fresh supply of pure drinking water?
Over 90 percent of the world's supply of fresh water is located in Antarctica. The Great Lakes in North America are known for having the most water suppy for the area.
How much of Earth's fresh is in ice sheets and glaciers?
Slightly over two-thirds (66%+) of the Fresh Water supply is frozen.About 69% has been estimated.

How does the water cycle ensure that water gets used again and again?
Earths limited supply of fresh water to be used over and over again.
How long does it take astronauts to go around the world?
It should take just over an hour and a half traveling at 17,000 mph.
Why is over half of Earth's water fresh supply difficult to use?
It is locked up as ice.
Will the current astronauts walk on the moon?
Yes they will , as the shuttle astronauts orbit the earth and the moon there are 3 moon landings that NASA has planed over the next 4 years. Which will include over 100 different astronauts in one way or another.
How long is tuna cups good for?
Keep the cup closed tightly and it will be fresh and new but not over a year.
Can astronauts take their pets to space?
yes. over years astronauts have taken animals in space to test them. they also see how long they can live in outerspace. 2 Russian dogs have traveled in Sputnik 5. They successfully traveled around the world be themselves
How long can you survive in a standard space suit in space?
Probably the rate limiting step is going to be your oxygen supply. Does this stranded astronaut have an umbilical supplying him/her with oxygen? Is the astronaut getting oxygen only from their backpack (PLSS)? Often these portable life support systems will supply fresh oxygen and use lithium hydroxide to scrub the exhaled carbon dioxide while recycling the suit's atmosphere. Another consideration is the amount of activity the astronaut is doing. The more active they are, the faster they will burn through their oxygen supplies. So, lets say there are two astronauts stranded on the moon. One is very active and is burning through the oxygen and lithium in his PLSS, he might last 4-6 hours. Let's say his comrade is laying very still--almost sleeping--trying to conserve his oxygen and lithium hydroxide. He might last 6-8 hours. There is an issue of electricity and water used to control the suit's temperature. If the astronauts kept themselves in the shadows (of the Lunar Module) they could save cooling water and electricity. Still, the amount of oxygen astronauts bring with them into space is finite. If they are stranded, they will eventually run out. In a larger space station, it would be possible to grow enough plants to PRODUCE enough oxygen to supply the astronauts with an ~unlimited supply of oxygen. However, if the astronauts became dependent on these plants for oxygen production, any problem with the plants (say, over exposure to sun light, under watering, etc...), could doom the crew.
How many hours per week do astronauts work?
Over 9000
