Space Travel Essay
1. Space Tourism
Key Notes:
Space Tourism is the term that's come to be used to mean ordinary members of the public buying
tickets to travel to space and back. Many people find this idea futuristic. But over the past few years
a growing volume of professional work has been done on the subject, and it's now clear that setting
up commercial space tourism services is a realistic target for business today.
But this idea of Space Tourism isn't at all familiar to most people, including the space industry,
who are used to the idea that space is for research or military activities. Few people are aware of how
much work has been done to show that tourism is a realistic goal, and how rapidly this work is now
progressing.

But these are small businesses – no more than a few $billions per year – that will never need humans
in space. So "commercial space activities" today are not leading towards space tourism.
Consequently specific efforts need to be made to set up space tourism services, because they won't
happen as a natural consequence of present–day space activities.
Some people say "Developing space tourism is very difficult, so it'll take a long time. Leave it to the
government space agencies." But the agencies already spend $25 billion per year on "space
activities" – and they are not trying to develop launch vehicles that could open space up to the
public. Barely 2% of their budgets are used for this purpose – although even just one year of their
huge funding would be plenty!
So Space Future is playing its part by collecting all the work that is going on, and making it
accessible, to help people to understand that this is the way to the space age.
Phases of Space Tourism
Like any other business, once space tourism gets started it will develop progressively. It can be
helpful to think of it as going through several phases. Starting with a relatively small–scale and
relatively high–priced "pioneering phase", the scale of activity will grow and prices will fall as it
matures. Finally it will become a mass–market business, like aviation today.

3. Space Persuasive Essay
Does it feel like there are too many humans overpopulating the Earth? Cause eventually the Earth
will have no more space for humans and has exhausted its resources making life difficult to prosper.
Well fear not, there are space companies like the National Aeronautics and Space
Administration(NASA) and SpaceX trying to search throughout the universe for the possibilities of
human survival. One of Jupiter's four largest moon called Europa, discovered by the Galileo
spacecraft created from NASA, believed to contain water essential towards human life. The more
reasons on why humans all over Earth should consider space exploration as one of the top
priority, because Earth's resources would slowly be depleted as time goes on. Therefore, the use of
space instruments to analyze evidence, viewing Europa's surface on the possibilities of finding
water, the building of fuel depots in space to refuel spacecrafts, and information from spacecrafts are
all necessary for human life outside of...show more content...
These robots, created in NASA's Jet Propulsion Laboratory, are required to handle Europa's rough
landscape on traveling and gathering evidence off of its surface. One cool gadget is the
nuclear–powered tunneling robot, it "melts chips of ice and spits them out of its rear end after
sawing them off" then also "take samples of the ice core to deliver back to the surface"(Kelly). The
off–road wheel robot is a type of robot has special wheels and suspension system to navigate the icy
surface of Europa against its moon's geysers that, "may shoot ice or gas, are likely to have very loose
sediment, or sand–like ice surrounding them"(Kelly) These robots are just select examples of how
NASA wants to ensure the protection of their robots and the evidence of Europa's ice surface. Other
than robots, the Clipper has space instruments that it will use as it takes multiple flybys of
