Comet probe Rosetta succeeded in the last mission "Comet Fall" and finishes the 12-year mission with Aibo Philae



September 30, 2016, the European Space Agency (ESA) unmanned spacecraft "Rosetta(Rosetta) succeeded in colliding with "67 P / Turimov / Gerasimenco comet" which is the total finish of the 12-year mission. With the comet landing aircraft "Philae", the world's firstLanding on a cometAll the mission accomplished feat such as accomplishment was completed by this.

At 11:19 on September 30, 2016, Greenwich Mean Time, at the time of Japan time, at 20:19 on the same day, we confirmed that the signal from Rosetta ceased at the control center of ESA in Darmstadt, Germany. In response to this, Mr. Sylvain Lodiot, Rosetta's Chief Operating Officer, announced the official end of the mission. At that moment, within the control center, a big applause blew up and the staff quietly hugged and felt each other hugging.


Rosetta said that it hit a comet of Churimov Gerasimenco at a speed of 90 cm per second, approaching at a speed as fast as a human walk and directly colliding. Rosetta is not equipped with a landing gear to ease the impact of the collision, so it is considered that the aircraft was destroyed at the same time as a collision.


A state of the graph showing that the radio wave was lost at the moment of collision is. You can see how things that were raised in the center like mountains changed to flat.


Screens showing a number of data communication packets sent from Rosetta are. A description of the data, generation time and reception time etc. are displayed.


And here is the screen "Screenshot of the last packet received from Rosetta". In the lower right corner of the screen you can see the last reception time "274th day of 2016, 11:19 minutes 36.541 seconds".


The last moment of Rosetta was broadcast live on the Internet, and the image captured by the camera was also released on the Twitter account for ESA's Rosetta. The state of the comet taken from the point 22.9 km away is now ...


Here is a picture of a shot of a collision point a little closer.


"Wow! Look at the wonderful shadow appearance seen from the 11.7 km point!" Tweet. As coming closer to the comet, the appearance of the surface of the earth becomes clearly visible.


Approaching 5.8 km altitude.


About 90 minutes after the above photo, the ground approached further.


Approaching to altitude of 1.2 km. The universe without air, the side of the shadow is a dreadful darkness of jet black.


Rosetta finally has the final moment. Images from the altitude of only 51 meters. Considering from the speed of 90 cm per second, it is thought that Rosetta collided with a comet after about 57 seconds from this image.


It was that Rosetta and Philae's character existed that was unique in Rosetta's mission. After the mission was completed, the tweets looking back on the past have been posted, talking about "mission accomplishment" in the language of countries around the world.

Along with the launch situation, "mission accomplished" in Italian.


Whether the state seems to have succeeded in detaching from the rocket or not, even in Spanish with the appearance that the control center is getting joyful "Mission accomplished".

Phillae to prepare for the landing point is decided. (Czech)


Then Philae is separated from Rosetta and enters the landing phase over 7 hours. (Greek language)


Since the injection device did not work well at the time of landing, Philae bounced several times and landed at a different point from the plan. (Norwegian)


Unfortunately, the landing site was a place where the light of the sun did not reach. If the sun does not hit as it is, power will be exhausted, but Philae will send the data to Rosetta. (Hungarian)


However, due to the shortage of electricity, Philae will temporarily fall asleep. (Maltese)


"Rosetta looks worried as" okay if it's okay ... ". After that, with the approach to the sun, the function of Philae temporarily resurrected, but since full-scale resurgence was in desperate circumstances, ESA abandoned continuation of Philae's operation. (Latvian)


In the tweet "Success" in Chinese, the image that the comet and Philae approaching it, the appearance of Philae who failed landing and hidden behind the rock are contained in the album.


To the tweet of Hindi's "goaled", an image called "Good-bye Rosetta!" From the earth!


In the tweet "Japanese mission accomplishment", Rosetta appearance together with exploration satellites that have achieved numerous accomplishments. Rosetta and Philae also show that it has become a history explorer.


Rosetta finally celebrated at last. The falling point was near Philae, and the state of the two people who fell asleep as close as possible was drawn.


In addition to that, in Philae's account, did you notice the landing of Rosetta? Philae's message "Rosetta, are you?" Was posted. There are many people who collapse the lacrimal gland in the state of the two people who are connected far away from the earth.


It is not a comparison with the previous exploration mission because it is characterized together with the great achievement of collecting data toward the elucidation of the mystery of the formation of the solar system by observation which succeeded in the mission of the first humanoid "comet landing" It was a unique part of the mission of Rosetta and Philae that I could emotionally transfer. The following movies that summarize the two-year time of Rosetta until Philae's landing mission and fall to the comet are also must-see.

By the way, according to @ Meatball P, the satellite that was drawn with Rosetta seems to be as follows.
