2. WHAT IS SPACE X
Space X is an Aero Space company that was founded in 2002 to revolutionize
space technology by Elon Musk.
SpaceX designs, manufactures and launches advanced rockets and
spacecrafts.
The headquarters of Space X is located in Hawthorne, California, U.S.
The company has 3 Rocket Launch Facilities, 3 Space X Offices, and one
development facility located in the U.S,
They have over 6,000+ Employee’s, and they currently have 3 vehicles.
(SpaceX, 2017).
3. ELON MUSK
Elon Musk is co-founder and CEO of Tesla and Space X.
Elon Musk is working to revolutionize transportation both on
Earth and in space.
His automaker, Tesla Motors, which was founded in 2003, is
bringing fully-electric vehicles to the mass market.
His real time Net worth is $21.6B.
4. WHAT IS THE PROBLEM ?
The bottom of the ocean is a rocket graveyard – littered with the expended shells
of thousands of rockets used to send satellites, and people, to space.
The cost of making a new rocket is too high.
Space Travel is still expensive.
Sending resources for research to international space stations is too complicated.
The journey of Humans to Mars is still a dream to come true.
6. SOLUTION BY SPACE X
SpaceX believes a fully and rapidly reusable rocket is the pivotal breakthrough
needed to substantially reduce the cost of space access.
The entire point of landing and reusing rockets is to save money: instead of
creating an entirely new rocket for each mission.
The Falcon 9, developed by aerospace company SpaceX, means it is now
possible to reuse the first-stage of the rocket, by flying it safely back to Earth.
Cost of manufacturing a spacex rocket is nearly 110 of present day rockets.

8. MECHANISM
In first stage it incorporates nine Merlin engines and aluminum-lithium alloy tanks
containing liquid oxygen and rocket-grade kerosene (RP-1) propellant.
The nine ‘Merlin 1’ engines booster give the rocket 600 tonnes of thrust needed
for lift-off.
Engines are gradually throttled near the end of first-stage flight to limit launch
vehicle acceleration as the rocket’s mass decreases with the burning of fuel.

10. The second stage, powered by a single Merlin vacuum engine, delivers Falcon
9’s payload to the desired orbit.
The second stage engine ignites a few seconds after stage separation, and can
be restarted multiple times to place multiple payloads into different orbits.
For maximum reliability, the second stage has redundant igniter systems.
Like the first stage, the second stage is made from a high-strength aluminum-
lithium alloy.

13. COLONISATION OF MARS
The objectives for the first mission will be to confirm water resources,
identify hazards, and put in place initial power, mining, and life support
infrastructure.
A second mission, with both cargo and crew, is targeted for 2024, with
primary objectives of building a propellant depot and preparing for future
crew flights.
14. The ships from these initial missions will also serve as the beginnings of the
first Mars base, from which we can build a thriving city and eventually a self-
sustaining civilization on Mars.
Starship will enter the Mars atmosphere at 7.5 kilometers per second and
decelerate aerodynamically.
15. ACHEIVEMENTS OF SPACE X
The very first attempt of space x rocket falcon 9 in January 2015 failed.
The second attempt also failed in April 2105.
At last in third attempt they succeeded in December 2015.
On April 2016 they made first successful sea landing.
Spacex Dragon becomes the first private space craft to visit the international
space station.
On September 2018 Falcon 1 became the first privately developed liquid fuel
rocket to reach earth orbit
Recently on January 6 2019 the Falcon 9 completed Static fire test.
They will announce targeted launch date once confirmed.
16. ADVANTAGES
The cost of manufacturing and launching of space shuttle costs $450 millon
per launch while it costs $133 millon for SpcaeX.
For now, space X launched reusable falcon 9 rockets while the cost of re-
furshibing costs only 12 of initial cost.
Some of the reusable rockets use kerosene (of rocket grade type) as fuel which
do not generate harmful chlorine as exhaust. This helps to protect the
environment.
Cost for launching becomes much cheaper as it reduces material cost due to
reusability.
Discarding of rockets into oceans and land can be avoided.
17. CONCLUSION
SpaceX brought a new revolution in space transportation.
We can effectively reuse rockets similar to airplanes, hence space travel will
become cheaper to a greater extent.
The dream Journey of Humans to Mars made more simplified.
Soon in near future it undergo further developments and serves humanity.
