Yes. Going to Neptune will not make you immortal! Everyone can and will die.
The journey to Neptune is likely to take more than 10 years. If you spend that length of time in weightless condition your bones will lose their strength and your muscles will not be able to support your weight - which, on Neptune will be greater than your weight on earth. Next, the atmosphere on Neptune is mostly hydrogen and helium, and contains no oxygen. So you will need to take all your oxygen with you or set up some way of producing it on Neptune. The average temperature on Neptune is about 215 Celsius degrees below than on earth so you space suit will need some serious thermal qualities. There will be no liquid water so you will find a way to get that and finally, there is no food so you will need to take all your food with you. These requirements will greatly increase the payload for your spaceship so it is likely to be a long while before anyone travels to Neptune!
If you were to visit Neptune, you would need a specialized space suit that provides protection from the extreme cold, high-pressure environment, and toxic gases found on the planet. This suit would likely be thickly insulated, with advanced life support systems to keep you safe in the harsh conditions of Neptune's atmosphere.
the human will die beacause there is no air on mars
Because you will die with out it.
u will die man theres no air in space
if you traveld on a space ship to neptune the space ship would freeze and crash and tou would die from the cold temperature
oxygen deprivation
well you can probably sleep in space if you had a space suit on....... but if not then you would die of lack of oxygen.
Remove your space suit and exhale big.
their is no air on mars so if they do not have on a space suit they will die.
Neptune is extremely cold. A person exposed to its atmosphere would freeze to death in seconds. If you found a layer that had surviviable temperatures, the lack of oxygen in the atmosphere would kill you. even if you had a space suit that provided air and protected you from the cold, Neptune has no solid surface, so you would simply fall into denser and denser atmosphere until you were crushed by the pressure.
You will die because you dont have a suit on. There is not oxygen in outerspace.
yes if you are in a space suit otherwise you will die
