upward bound discuses about the different and innovative ways to get into space
cheaply.

We have always used rockets
to go to space but they are rubbish, very much expensive, always wasted after
one shot, polluting, takes a lot of fuel to get into space and more fuel to get
that fuel into space which is really inefficient.

For more efficient space
travels we had some ways which we would use:-

 

 

 

 

1.7.1. SKYLON

It is vast thunderbird jet
plane which is a rocket jet hybrid. It takes off like a normal plane, flies
into space, delivers cargo up to 11tons to the ISS or other space stations then
flies back home, refuel and take off again.

The secret to Skylon is the
SABRE engine. Most planes have big heavy engines which operates limited power
to control their temperature. Skylon doesn’t. Innovative cooling system in the
nose freezes air from a 1000oC to 150oC where it’s burned
with onboard hydrogen fuel allowing the engines to be lighter and run up for
higher loads.

It accelerates 5.4 times the speed of
sound which goes 60 miles high. Once there, it shuts off due to very thin air
supply and uses onboard oxygen to rocket into the orbit. It is very reliant and
uses 1/5 the fuel of a rocket.

 

1.7.2. LIGHTCRAFT

To get into space you need
thrust but what if we had a beam of thrust from the ground rather than fuel
carried on board and therefore becoming lighter and efficient ship.

Lightcraft has a special
mirror beneath the craft which focuses laser light beamed from the ground
pointing directly beneath the aircraft. The air is heated to 50,000oC
which is 10 times hotter than the surface of the sun and then explodes.

The shockwave pushes the ship
up. It’s estimated that if we use 100megawatt laser and 1.4 m mirror we can
deploy satellite payloads to up to 100kg could be sent rapidly and more cheaply
to the ISS and other platforms.

 

1.7.3. SPACE ELEVATOR

Space
exploration can be done more efficiently and effectively but the thing that
lies’ being a hurdle is a dirty four little word COST. For taking just a
kilogram of anything into space requires $20,000 and would be 8 million for an
average person and billions for an international space station.

So we decided of a way which
would lower the $20,000 to as low as $200. And the way is building a space
elevator.

The
fuel required for a rocket to go to like we can say to mars is consumed half of
the way down for just escape earth’s gravity. Space elevator would make this as
simple as clicking the up button.

Space
elevator involves a counter weight, tether, anchor and the climber. Anchor
sticks to the ground, counter weight acts as a weight which must be on the
geostationary orbit which is 36,000 km from the surface of the earth, the
tether which is a cable connecting the anchor and counterweight, and the
climber which climbs up the tether.

Carbon
Nano tubes, graphene and diamond Nano threads can be used to make the tether
which needs to be strong, light and flexible. For creating a space elevator on
earth we would require these materials in a huge quantity which is not
practical as these materials have the longest created size of 2-3cm. We could
make a space elevator on moon or mars with present technology and materials
like Zylon and Kevlar. Building a space elevator on moon or mars is more
beneficial as these bodies have very low gravity letting us build the space
elevator easily with strong materials like Kevlar which are weaker than CNTs or
carbon nano tubes but can be mass produced. Space elevators can have multiple
tethers to stabilize the force generated when the climber moves up or down.
These multiple tethers could have their own climbers or a single climber which
would go from one counterweight to another.

1.7.4. SPACE TOWER

A space tower is basically a tower but
quite high and has a docking station and launch pad from which we can land,
refuel and launch our different space crafts. For our case we would be building
a ThothX tower which would act as both space elevator and space tower combined.
But it is not a full space elevator. The tower would be
built out of stacked Kevlar cells inflated to extreme pressures with hydrogen or helium gas. Flywheels would
be used to stabilize the structure, as the structure is much too tall for guywires to work. The tower is designed to be able to
survive Category 5 hurricanes. It is a 20km tall tower but
we would make an approximately 200km tall tower. This tower will also be used
as a communication tower, a replacement for low altitude satellites and high
altitude wing electricity generator.

 

So in
conclusion we will be building a ThothX tower on earth with an altitude of
200km. For transporting materials for the initial stages of NOVUS TERRA we
would use Skylon and Lightcraft for the purpose.  NOVUS TERRA in its initial stages will also
get materials from the moon base. The Kalpana station and Gagarin station would
be constructed on moon (discussed further). Mars would have its base with a
space elevator equipped with multiple tethers (discussed further).
