SpaceX achieves the feat of successful launch of the rocket, Mr. Mask says "Next time it will be re-launch within 24 hours"



SpaceX, a rocket development and launching company launched by Mr. Eulon Mask, successfully launched "local reuse" of the world's first Falcon 9 rocket on March 30, 2017 local time. This greatly expands the possibilities for the realization of the goal of "SpaceX reusing rockets to drastically reduce the launch cost", which is exactly what you call historical accomplishment.

SpaceX Has Reused Its First Rocket - MIT Technology Review

The state of launch was live broadcast on SpaceX's YouTube channel. You can still watch recorded things even now.

SES-10 Hosted Webcast - YouTube


In the state of Florida, USAKennedy Space Center 39th Combined Launch FacilityWait for the launch in Falcon 9 rocket. In the upper right of the screen, the remaining time until launch is displayed.


What will be launched this time is the communication satellite operated by SESSES-10.


To launch this SES - 10, the first stage booster of the Falcon 9 rocket which carries out the launch once is used. This booster succeeded the CRS - 8 mission in April 2016, and after the launch and separation it was automatically landed on the offshore drone ship "Of Course I Still Love You".


The recovered booster was disassembled and maintenance was done for reuse. 9 units are used per machineMerlin engineI am lined up.


Paper of "Do not touch the flight hardware".


Merlin engine to be treated distinctly from ordinary engines.


And all the maintenance completed Falcon 9 rocket is installed in the launch facility and wait for the launch time. On March 28, the engine combustion test before the launch was carried out, and it was confirmed that it operates without problems.


On the tip of the rocket is a cover called "fairing" which was written as "SES". It is intended to protect the objects during launch, and in this there is enough space to fit the small bus all the way. As will be described later, in addition to the booster at this launch, we have succeeded in returning this fairing to the ground.


The clock on the upper right shows "T - 00: 01: 00", one more minute to launch. A computer installed in the Falcon 9 rocket took control of the aircraft.


And 1 second ago, 9 Merlin engines caught fire ... ...


The Falcon 9 rocket began to rise while blowing out a red flame.


"Tower clear" away from the launch tower in about 9 seconds from lift-off (launch). I will rise while I raise the speed.


Approximately one minute after liftoff the aircraft speed reached sound speed. At this point Falcon 9 reaches the "Max Q" where the maximum pressure is applied to the aircraft due to pressure and machine speed. Falcon 9 slightly weakens the thrust of the Merlin engine and continues to rise while adjusting the burden on the aircraft.


And about 1 minute and 30 seconds later, when the altitude reached around 14,000 meters and the influence of air pressure became weak, the Falcon 9 rocket returned thrust to full power again. In other words, a great cheer is brought up from the staff of SpaceX who watches the launch because it cleared the moment that burdens the most aircraft.


And one of the most important moments, the moment of separation of the first stage booster comes. The picture shows the camera (left) attached to the first booster and the camera (right) showing the downward from the second booster side.


At the moment of separation, "MECO (Main Engine Cut Out: Mecoe)" to stop the engine of the first stage booster was performed, and the booster was separated. A big cheer from the venue.


Then, the ignition of the engine of the second stage rocket is completed, the first stage booster goes through the duty given. The cheers of the hall will heat up further.


And the first stage booster started descent aiming at a drone ship. Control the trajectory by performing entry burn (inrush injection) and control posture and orientation using "grid fins" like the net.


The moment of returning to the drone ship soon. If successfully successfully arriving at the ship, this will be a great success with no point of complaint anymore.


At the moment I thought that the flame of the booster had changed, a part of the drone ship changed to orange and the picture stopped ......


Black out as it is. A roar of "Hey ~ ~" rises from the venue.


But a couple seconds later, this time the reporter got a bitter cheer to laugh.


On the screen, the state that the first stage booster was standing firmly with 4 legs was displayed. The moment that remains in the history of rocket development now is that it is launched once and the reused rocket is launched again, and moreover, it gets docked to a drone ship two times.


Mask CEO who was watching this appearance also appeared on the screen.


Ms. Mask who usually posts comments on Twitter, but this time it is a lively broadcast comment with a feeling of excitement. "Today is an incredibly wonderful day, I succeeded in reinstalling a booster of a scale that could put satellites into orbit and after successfully delivering the second stage rocket, I returned safely to the drone ship Today was a terrible day for those involved in space development The first stage booster is the most expensive part of the whole rocket and this is a tremendously innovative thing in space flight It took me 15 years to complete it, it was a really long time, I am very proud of the development team and I have achieved a milestone here today. "Thank you."


After that, the 2nd stage rocket revolves around the earth while observing the timing, heading towards a higher altitude orbitStationary transfer orbitImplementation of injection to ride on. Unfortunately we can hardly see the situation after that, but it seems that we continued flight successfully.


And, as mentioned above, in this launch, in addition to the booster, the fairing at the tip of the rocket also returned to the ground. The fairing is a pair of separation type with two pieces, and it is a large part that also costs 6 million dollars (about 700 million yen) made of aluminum honeycomb and composite carbon material. By installing an injection device in each, it is possible to return to the earth on the target trajectory. Although it seems that only one return has been confirmed this time, it is considered that fairing was opened to parachute and arrived somewhere in the sea.

Although SpaceX achieved achievement, Mr. Mask took the morning without thinking "I am very proud of the team of SpaceX which achieved milestone of space development! The next goal is re-launch within 24 hours!" I muttered for the first time I was about to get out. It is a place where I think that it is impossible if it is normal, but it is mysterious because it seems that SpaceX will realize why.


By the way, the movie that the camera captured the appearance of the first stage booster returning to the ground is Kore. At first, the booster which descended at the speed of surprisingly rapidly decelerated with the injection of the engine, and it became clear that it was almost stopped by the time it got to the drone ship, and I thought "human beings like this Is it also possible to do ...? "It seems to muttered. However, this is a picture of falling down and exploding on the last ship wrestling success in 2015.

Regarding private rocket development, development by "Blue Origin" launched by Amazon's Jeff Bezos is underway, and in March 2017 it was reported that the assembly of a large rocket engine was completed I will. From the remarkable progress of space development led by the private sector, it seems that we can keep an eye on from now on.
