What are some problems with zero gravity?
Long-term exposure to the zero gravity causes multiple health problems including redistribution of fluids and loss of bone and muscle mass.
What can you not bring into space?
Common items like salt and bread are banned from the International Space Station due to fears that they’ll send floating pieces everywhere and potentially damage space equipment or accidentally get inhaled by astronauts. Basic eating, sleeping, and showering habits must also be modified.
Do lighters work in zero gravity?
A three-foot-long controlled flame in zero gravity is the biggest NASA has ever attempted. If you light a match on Earth, the flame is long and pointy because hot gases rise upward from the flame, keeping it straight and sticking up. But in space, buoyancy does not exist — so the flames spread out in all directions.
Can fire exist in zero gravity?
FLAME IN MICROGRAVITY is spherical owing to a lack of buoyancy and convection. The flames didnt self-extinguish because the launch pad was not a gravity-free environment. Oxygen could still reach a flame in a gravity-free environment if someone blew the gas into the flame or let it “diffuse” in.
Can you breathe in zero gravity?
Answer 2: Zero gravity has nothing to do with breathing. If there is air, then you can breathe it; if there isn’t air, then you can’t. Gravity on planets tends to attract atmospheres, and this means that planets with gravity may have breathable atmospheres, unlike the vacuum of space.
Can a fire burn in space?
Fires can’t start in space itself because there is no oxygen – or indeed anything else – in a vacuum. Yet inside the confines of spacecraft, and freed from gravity, flames behave in strange and beautiful ways. They burn at cooler temperatures, in unfamiliar shapes and are powered by unusual chemistry.
Can you light a fire on Mars?
As the atmosphere on Mars is largely Carbon Dioxide based with little or no traces of Oxygen, the possibility of an Open fire is pretty low. Also, it is so thin and near to the vacuum of Space, it can’t really support combustion.
