Space Travel is very expensive and it also has a very negative effect on the environment, but it helps mankind understand much more about everything in the universe which satisfies our curiosity. In the aspect of understanding our universe space travel is very necessary.
But how does it really help us? If a major comet the size of a mountain comes along (which happens every 100,000,000 years) and we, because of space travel, can stop it, well then space travel has been a very necessary thing indeed. If that doesn't happen, I'm not sure if you can class space travel as a necessity. Why should people starve in the world when so much money is spent on space travel? You can't eat rockets...
It's a matter of opinion if space travel is a necessity or not. I for one think our understanding of the universe is important in several aspects, such as understanding how unique we are and how unique life is and I hope we can come to appreciate it more then we do today.
In addition I believe that the moon landings cost about five percent of the tax money during those years (if you know the correct numbers please tell me) Ask yourself if you think that money was well spent and if that was necessary.
well sound actually always needs a medium so it can travel, in space there's is no sound because there isn't a medium it can travel through. but just about anything is a medium for sound. air is also a great medium, that's why were able to hear one another
Same as an astronaut. A person trained by a space program to travel into space as a crew member of the space program.
Light waves, like all electromagnetic waves, travel without a medium, so they can travel through empty space. Sound waves, on the other hand, do require a medium to travel or propagate; therefore, they can not travel through empty space.
electro-magnetic radiations Light.
No. Because the solids have no space to travel into.
Two limiting factors to space travel are the high cost of building and launching spacecraft, as well as the long-term effects of space radiation on astronauts' health. Developing the necessary technology and infrastructure to support long-term human space travel is also a significant challenge.
I'll say that ALL technologies are involved in space travel, and I'll challenge other contributors to name some branch of technology that's NOT used in any way to design, construct, launch, control, and monitor space vehicles.
space travel denefits me =)
Yes, we do have technology to travel to space.
Space travel is done by means of rockets.
Radio waves are a type of electromagnetic wave that do not require a medium to travel through, allowing them to propagate through the vacuum of space. In contrast, sound waves are mechanical waves that require a medium, such as air or water, to transfer energy and vibrations. Space is a vacuum, lacking the necessary medium, which is why sound waves cannot travel through it.
For conduction and convection we need a material medium. But for radiation such a meaterial medium is not necessary. So in free space radiation can pass through easily.
We Travel the Space Ways was created in 1956.
they would travel in a space shuttle
People who travel in space are called astronauts.
Roberta Bondar travel in space on January 22,1992. She was in space for eight days.
Before going into space, you need to undergo rigorous physical and psychological evaluations to ensure your health and readiness for space travel. You also need to undergo extensive training on spacecraft operations, emergency procedures, and other necessary skills for space missions. Additionally, understanding the risks associated with space travel, such as radiation exposure and microgravity effects, is crucial.
