Would you be able to suck juice with straw in the moon?

Answer 1

No, unless the moon suddenly gained an atmosphere and grew oxygen out of no where, unless that happened that would be an impossible feat.

(The oxygen would only be required to breathe. Ignoring that requirement, any atmospheric pressure would suffice.)

Liquid is never "sucked" through straw into your mouth, instead it is pushed by the atmospheric pressure. Without an atmosphere pushing on the liquid in the cup, nothing would ever move. (Actually, quite the opposite would happen if you had any air in your mouth to begin with: the air would blast out of your mouth into the straw and spray the liquid everywhere all over the Moon.)

If, however, you were in the lunar module drinking through a straw would be easier than on Earth. Astronauts perform a similar feat all the time, even in a weightless environment orbiting the earth.

Answer 2

Yes. The astronauts lived for up to 3 days on the moon. They ate inside the Lunar Module before and after their moonwalks. The asatronauts spent almost 8 hours in their suits, and the work they performed was very strenuous. They neeeded something to keep then hydrated. During their moonwalks, they ate from a fruit bar that was attached inside their space suits. They also drank water or Orange Juice to keep hydrated while walking on the moon.

The only astronaut unable to drink during his moonwalk was Apollo 15 LMP Jim Irwin, who was unable to get his straw unclogged. He suffered a very mild heart attack while working on the moon because of lack of hydration. His heart attack was so mild in fact that he wasn't informed of it until after Apollo 15 splashed down in the Pacific Ocean.

Answer 3

Drinking though a straw requires making the pressure inside your mouth lower than the pressure outside, which forces the drink up the straw and into your mouth. The moon has no atmosphere, so the pressure there is already zero.

Answer 4

Most definitely. The astronauts had things to drink (water or orange juice) inside their suit while they were walking on the moon. They also had fruit or nut bars to eat. They were in the suits almost 8 hours. The only astronaut unable to drink during his moonwalk was Jim Irwin (Apollo 15 LMP) because his straw was clogged.

However, that was inside a space suit (or the Lunar Lander) where there is AIR. If you were outside, with no space suit, you could not suck thru a straw, since there is no air pressure to push liquid through the straw.

Answer 5

No, as there is no atmosphere on the Moon drinking juice from a straw will not work for the following reasons.

• the water in the juice will boil away in a few seconds due to the depressed boiling point of water.
• the second law of thermodynamics will disperse the evaporated water radially so no coherent fluid can exist
• with no external air pressure the process of sucking will produce no negative pressure gradient for the water to follow.
• the astronaut will not be able to insert the straw into his pressure sealed space suit to attempt to apply a sucking maneuver. Attempting such is ridiculous anyways as the zero pressure of space and would just result in him getting sucked out of his/her space suit.
• Oranges don't grow on the moon so there is no orange juice to be had.
• Retail stores don't (as yet) exist on the moon so there is no possible way for orange juice to be retailed for foolish astronauts to attempt drinking it. (Or any juice for that matter. The question wasn't specific.)
• Anita Bryant doesn't live on the Moon so no one would know about orange juice and its virtues to want to attempt such a thing.
• There is currently an orange juice embargo against the Moon so no orange juice can be imported for anybody to attempt drinking it there. (Tang doesn't count as orange juice.)

Yes, if all the aforementioned problems are curtailed (such as smuggling a juice fruit contained up to the Moon in a pressured space suit. Then the astronaut inside the space suit could suck up the orange juice perfectly well. Anita would have to tell him/her it was there of course.)

Answer 6

That would depend on the exact situation. The reason sipping works is that the outside air pressure pushes on the water pushes it up in the straw when there is less pressure in the straw.Living under an artificial atmosphere, that should work on Mars as well.

On the other hand, the natural atmosphere on Mars wouldn't provide much pressure.

Answer 7

Anyplace where you could breath - yes. In "raw" Mars air - no, its to thin (and you'd be dead).

Answer 8

Not outside your space suit you wouldn't.
