Can we
create fuel in space? You might be thinking, “Why would people want to do
that?” This is an interesting question because many space applications require
us to produce fuel and oxygen in weightless conditions. Only then can we launch
these things into orbit. This article will discuss the possibility of creating
fuel in space.
It's not just
possible, it's happening.
A recent article in The New
York Times described how NASA is developing fuel that could be used by
astronauts to travel to Mars. In a nutshell: NASA is working with a company
called NanoRacks, which builds "spacecraft-like" stations in orbit
around Earth. One of those stations (called the International Space Station)
has a large room where astronauts can experiment with different types of fuel.
The goal for NASA is to create
fuel that can be stored for long periods of time and then used as needed.
They're doing this because they want to be able to transport astronauts from
Earth to other planets — perhaps even Mars — without having them carry any
extra weight.
How fuel can be created in Space?
It's a new era of space
exploration. In the future, people will be going to Mars and lunar missions in
2017. In order to explore the moon and Mars, rockets are used by rockets
engines. But rockets are used in the space so how can we create fuel for
rockets? So today I'll show you some science about how fuel can be created in
Space.
1. Water
Water is the most abundant
chemical element on Earth and is a key part of life. Water also plays a key
role in space, as it is used for life support and for rocket engines.
Water can be created in space
by using solar energy to split water molecules (H2O) into hydrogen and oxygen.
This reaction requires light and heat, which are abundant in outer space. The
hydrogen produced can then be used to create rocket fuel or fuel tanks for
spacecrafts.
2. Sunlight
The sun is not a reactor, but
it can make fuel. The sun gives off massive amounts of energy in the form of
light and heat, which we know as sunlight.
The same process that gives us
solar energy also makes fuel, as well. The hydrogen that is created by
splitting water molecules by the power of light is freed up as fuel for rocket
engines.
We use the sun's power to split
water and make fuel. We collect up the free hydrogen and store it in giant
tanks called Lagerweygas. Then, when we need more fuel, we release it to new
rockets that blast off into space with brand new supplies.
3. Mercury
Yes, we can.
Mercury is the closest planet
to the Sun, and also the most reflective. Mercury's extremely dry atmosphere
makes it an excellent place to test new spacecraft technology.
The challenge with launching
into space is that you have to launch your craft before it gets too far away
from Earth. Once it gets too far away, it will be hard to get a signal back
because of the time delay involved. If you're lucky, you might catch a glimpse
of your craft on one of Mercury's three natural satellites, but that's about
it.
So how do we send things there?
We send them in a high-velocity ejection from an interplanetary rocket, or
perhaps from a solar sail if we could figure out how to make one large enough
for our purposes.
4. Magnesium
In space, a fuel could be
created by electrolysis of water. The main problem is that there is no oxygen
in space and the process requires a lot of energy.
Magnesium is another element
that can be used as a fuel but it can only be used in space for short periods
due to its toxic properties.
Magnesium and water can be used
to produce hydrogen and oxygen, which can be used as a single-source fuel.
5. Aluminium and oxygen
The first material we need to
make fuel in space is aluminium. We can't use metal because it would be too
expensive to send up, so we'll use plastic instead.
The problem with using plastic
is that it's not very efficient at generating energy. It only produces a few
hundred watts of power per tonne of material, compared with around 2kW/t for
aluminium.
So what do we do? We get rid of
some of the oxygen, so that there's less to react with the aluminium
pre-treatment. This makes things simpler and reduces costs further still.
A simple way to do this is by
heating the aluminium in an oven at about 700°C for four hours.
Conclusion:
Finding cheap space based
technology for the production of fuels and energy has been an ongoing concern
for some time. Space exploration is problematic in this regard because mass to
propulsion is required, which can prevent even the simplest of functional
missions from going underway. Not only could this technology work, it may be
cheaper as well. This is just the kind of innovation that space exploration
needs, which may lead to a wealth of discoveries including answers to mankind's
energy problems.
