If by spacecraft you mean those that have a human population and not a satellite then the reasons are vast:
- To test some theories in zero gravity.
- To study the atmosphere
- Test materials in the vacuum of space.
- Learn about various organisms ability to cope in zero gravity such as plants. (I heard they made beer on the space station during a funded experiment, and then sold it to enthusiasts to further assist funding)
- Observe the earth and objects on the earth from above
- To maintain satellites that are in orbit
- Collect junk in orbit that no longer works
So many other reasons, that researchers don't have too hard of a time getting funding from investors.

Why do active planet genarally have fewer impacts than bodies like the moon?
Two reasons. The moon no longer has active volcanoes to cover meteor strikes and the moon does not have an atmosphere, so strikes that would otherwise be burned up in an atmosphere are not burned. Plus there is not erosion to speak of on the moon.
Why is atmosphere important?
The atmosphere is important for two main reasons. It is the air that you breathe so, no atmosphere, no breathing. The other reason is it protects you by burning up the meteoroids that could hit earth.
Why is Venus hotter then earth?
Two reasons I know of; Venus is closer to the Sun than the Earth is. Venus has a very thick CO2 atmosphere that captures much of the solar heat.
Is it better to make astronomical observations from the Moon's surface or from a low earth orbiting observatory?
One of the main reasons why there is a push to construct a base on the moon is because telescopic observations from the moon would be clearer due to the fact that there would be no interference from an atmosphere, as is experienced on the Earth.AnswerMoon AnswerThe heavy mirror in a large telescope becomes distorted in a gravitational field when fixed on the earth, which would happen even on the moon with its reduced gravity. This reduces the quality of the image. Actuators placed under the mirror are used to minimise this effect in some large modern telescopes (called active optics, see reference). However, orbiting the earth in space the telescope mirror becomes weightless and these effects can be virtually eliminated. This simplifies the telescope design and the subsequent image quality should be improved.An orbiting telescope would also be cheaper to launch and service than one located on the Moon.
Carbon dioxide build up in your atmosphere for two reasons what is the best example of the prob?
The best example of carbon dioxide build up in the atmosphere is the burning of fossil fuels such as coal, oil, and gas for energy production. Additionally, deforestation and land use changes also contribute to increased carbon dioxide levels in the atmosphere, leading to the greenhouse effect and climate change.
Reasons why the earth's atmosphere survives?
yeah
Carbon dioxide is used for putting out fire-give reason?
2 reasons why carbon dioxide is used in putting fire off
When did ford start putting air bags in their cars?
in 1973, it was considered optional. For safety reasons they starred putting airbags in every car in 1974
What are the reasons the moon might be a good place for an optical telescope?
no atmosphere
What is the Important reasons for the correct seating position?
you might die your putting yourself at risk
Why are superalloys used for spacecraft?
The excellent mechanical strength and durability of superalloys are the reasons why it is mostly used for spacecrafts. Super alloys also have a very good resistance at high temperature and mechanical stress.
How do plants decrease global warming?
By taking carbon dioxide out of the atmosphere and turning it into oxygen, using the carbon atom for its own uses. Unfortunately, they cannot all do this fast enough because we are constantly putting out things that produce CO2and then chopping down trees for various reasons. :-/
What will be the reason that people never came back after going to space?
There are many possible reasons. There is a high chance that a failure could happen with any of the spacecrafts systems. There is a more obscure reason: When your in Space the low gravity the spacecraft creates isn't putting enough pressure on your body. Then the minerals in your cartilage will not be used as much. Then your body decides that you do not need these minerals. Once you come back to Earth you can have many bone and marrow problems... That is it in its simplest form.
What are some reasons for putting shoes on a horse in the first place?
They protect the hoof and they help the horse from not slipping
5 reasons that the atmosphere is important?
Five reasons that the atmosphere are important are that the atmosphere helps protect us from the sun, provides the oxygen we need, helps to keep all the elements we need to survive in the air close to the earth, it helps bounce harmful rays away from the planet, protects us from space debris.
Why moon has practically no atmosphere?
The Moon has no atmosphere for a number of reasons: It is not dense or big enough to have a gravitic pull to retain anything. It does not revolve, so it cannot hold on to anything like atmosphere. It has never had one.
What is most common forms of medicare fraud?
When people abuse the system by putting in claims for non-existent reasons.
