SpaceX: Reinventing Future | Creating History | SpaceX Launch
SpaceX is a
private aerospace company that is also known as a space exploration technology
corporation. They are specialized in aerospace manufacturer and space
transportation service.
The company
was started by Elon Musk in 2002. The main motive of the company is to minimize
the cost of space transportation and the colonization of Mars. SpaceX has
developed many launch vehicles and Dragon spacecraft.
SpaceX is
the first private company to make a liquid-propellant rocket(Falcon-1 ) to
reach the earth’s orbit. First, a privately funded company to send a spacecraft
to ISS(International space station) and also to orbit the sun.
SpaceX sent
a Tesla car to space which is currently flying in space.
These achievements
are done through the perfect collaboration with NASA. With this collaboration, SpaceX
has developed a Human rating certificate to safely transport humans to space
and bring back.
The first flight
demonstration required by NASA was done on March 2, 2019(Crew Dragon Demo). Set
to launch its first flight on May 27, 2020(Crew Dragon 2).
Vertical landing
was first established with Falcon 9 on December 2015. And also landed on the
ocean drone ship in April 2016.
On announcing
the launch of Starlink Project, and become the largest commercial satellite
constellation operator in the world.
CEO of
SpaceX Elon Musk announced the interplanetary transport with private fund and
launch system was developed.
Some achievements of SpaceX are
- Falcon 1 first privately funded liquid-fueled rocket to reach orbit.
- First private space company to launch and recover the spacecraft.
- First private space company to spacecraft to ISS.
- First relaunch and safe landing of used rocket.
- First private company to send orbitary to the sun.
- First company to send autonomous spacecraft to ISS.
Launching into
space
Falcon 9
will be launched on May 27, this would be the second crew Dragons demonstration.
This also called demo mission 2.
The flight
will be tested with NASA astronauts Bob Behnken and Doug Hurley will return
human flight to earth.
The launch window
opens a 4:33 p.m EDT with a backup launch available on May 30 at 3:22p.m. EDT
and on Sunday, May 31 at 3:00 p.m.
SpaceX human flight will be certified by NASA.
Different
stages of Launch
Liftoff- The
first stage is to liftoff. first and second stage is separation. The second stage
accelerates to orbit velocity.
Orbit
Activation- the second stage is the separation
of Falcon from Dragon and performs initial orbit activation and checkouts the
propulsion, life support, and thermal control systems.
Phasing Burns- Delta velocity orbit uplift maneuver which
pushes to the international space station.
Approach Initiation- Linking with International Space
Station to get command for final orbit rise.
Proximity Operation- Dragons makes connection with the international
space station for relative navigation.
Docking & Pressurization- final approach to docks with
the international space station and pressurize and dock opens.
Docking- SpaceX Dragon crew will check for the control
system and test for environment control and life support.
The spacecraft is designed to work autonomously but the
mission Crew will need to monitor the approach and docking.
Different
Stages of Return
Departure-
The Dragon will autonomously detach from the international space station and
burn to move away from the orbiting space station.
Phasing Burns- The Dragon performs the series of lowering
process aligning to landing.
Trunk
Jettison- The Computer orders the Dragon to unburn and save the propellant.
Deorbit
Burn- Deorbit burn, which lasts ~12
minutes.
Re-Entry- Entering
into earths atmosphere, Dragon experiences excess heating and drag.
Parachutes
deploy- Two drogue parachute at 18,000 feet, and the four main parachute at
6,500 feet.
SplashOff-
With the help of main parachutes, the velocity downs. The Dragon splashes in Florida’s
Atlantic Coast.
