What is the two properties of gravity?
Property 1: The gravitational force is a long-range force, which exists between two particles, regardless of the medium that separates them. Property 2: The gravitational force is directly proportional to the product of the mass of the two bodies. This means a larger mass will yield a larger force.
How was gravity proven?
The “proof” of gravity is the demonstration that the phenomenon happens. A casual demonstration would be to hold an ordinary object out in the air at arms length and let go. The object and the Earth just accelerated towards each other when there was no other significant force acting.
Are there any dead bodies in space?
The recovery team found the crew dead. These three are (as of 2021) the only human fatalities in space (above 100 kilometers (330,000 ft)).
Is the flag still on the moon?
Since the nylon flag was purchased from a government catalog, it was not designed to handle the harsh conditions of space. A review of photographs taken by the Lunar Reconnaissance Orbiter (LRO) indicates that flags placed during the Apollo 12, Apollo 16, and Apollo 17 missions were still standing as of 2012.
Why do astronauts drink their own urine?
Unluckily for the astronauts, it’s turning their own pee into potable drinking water. The end result is what she calls “good clean urine distillate” that gets put into a water processor for further filtration before the astronauts actually consume it. To paraphrase Neil Armstrong: It’s one small drip for man.
Does astronaut drink their pee?
Even astronaut urine is captured and processed to make it drinkable. The system that does this work is about to get an important upgrade. The ISS water recovery system is tasked with turning wastewater into potable water. The urine-processing part of the system has been an ongoing concern.
Can you drink urine through a LifeStraw?
LifeStraw filters do not remove dissolved salts and are not designed to be used to drink non-diluted urine. Because of this, we do not recommend drinking urine with the LifeStraw in even low amounts.
Can you drink water in space?
What do astronauts drink in space? Astronauts mainly drink water while in space, but flavoured drinks are also available. Freeze-dried drink mixes such as coffee or tea, lemonade and orange juice are provided in vacuum sealed pouches.
What food is not allowed in space?

- Bread. U.S. Food and Drug Administration.
- Alcohol. United States Embassy, Berlin.

- Soda. Getty Images / iStock.

How do astronauts brush their teeth?
First, the astronaut attaches their toothpaste tube to a nearby wall. Then, the astronaut takes their toothpaste and repeats the same process. They will brush their teeth like usual! Once they are done, all they have to do is squeeze some water over their brush and wipe it off with a towel to clean it.
How do astronauts shower?
On the ISS, astronauts do not shower but rather use liquid soap, water, and rinseless shampoo. They squeeze liquid soap and water from pouches onto their skin. Then they use rinseless soap with a little water to clean their hair. An airflow system nearby quickly evaporates excess water.
What’s the longest someone has stayed in space?

How do you know if you’re upside down in space?
The signals from an astronaut’s body in space go haywire in weightlessness. The inner ear reports that it is falling, but the eyes show that nothing is moving. As fluid shifts to the head, the brain usually interprets this extra pressure as a sign it is upside down – but in space there is no up or down.
What happens to waste in space?
Current waste disposal methods on the International Space Station rely on astronauts manually processing trash by placing it into bags then loading it onto a designated vehicle for short term storage, which depending on the craft, returns the trash to Earth or burns up in the atmosphere.
