Discovered a missing comet landing aircraft "Philae" ahead of the universe, successfully photographed a partner "Rosetta" ahead of the end of the mission



To circle the sunTurimov · Gerasimensko CometAlthough it landed, the European Space Agency (ESA) decided to abort the operation because of insufficient photovoltaic power generation The comet landing aircraft "Philae"It was announced that the comet explorer Rosetta who was exploring with Philae successfully shot from the sky.

Missing comet lander Philae spotted at last: ESA (Update 2)

This picture shows the philae. Where is Philae on the surface of the comet of rugged and rocky comet Turimov Gerasimenco ......


This part of the right edge of the photo. You can check the appearance of Philae in the shade part of the field angle which is about to be overlooked a little more.


When I enlarge the image, it looks like this. The picture is taken from the sky 2.7 km away from Philae, and one pixel is 5 cm resolution.


Entering the name of each part in this image is like this. Just to note that the aircraft fell sideways and the three legs are floating in the air.


The landing gear "Philae" was launched from French Guiana on March 2, 2004 with the Mercury Explorer "Rosetta". Approximately ten years later, in August 2014, we approached the comet of Turimov · Gerasimenco while approaching the speed, and on November 12th the same year I succeeded in landing the landing gear Philae to the nucleus of the comet. Japanese spacecraft "Hayabusa"Reached the asteroid" Itokawa "in 2005, which preceded this, Philae had accomplished the feat of" landing "for the first time in mankind on the surface of the comet.


However, at the time of landing Philae bounced 2 times and disturbed his posture, landed 1 km away from the planned landing site. Power was not secured because the point was not enough to receive the light from the sun, and Philae's mission was in a crisis situation. After that, Philae was put into "dormant mode" to wait for the comet to approach the sun, and we decided to wait for the time of the resurrection.

As the comet approaches the sun Philae got enough power and succeeded in restoration. On June 13, 2015, Rosetta and Philae's control center succeeded in receiving radio waves from Philae. After that, although sporadic communication was successful, there was never a full-scale restoration.

Later, as the comet moves away from the sun, the situation in Philae changes to a desperate one. And on July 26, 2016 Phila's official Twitter says, "It seems time has come to say goodbye soon, the power supply of Rosetta's communication unit will be forever dropped tomorrow," said goodbye Tweet tweets, Philae to go to sleep eternally.


Just before that, I am doing crying tweets "I am in a place far from the earth and the sun! I am with memories with you, send me a letter from the earth! People posted messages and the landscape of the earth for Philae.





Following Philae's sleep, the prospecting machine Rosetta will "landing" to the comet on 30th September 2016 and close the mission. Although it is landing, Rosetta is not equipped with a landing gear, so it is seen that Rosetta will be destroyed by the impact of landing. Although this is a very difficult mission, it is often unknown whether actual collision is possible or not, but ESA aims to realize it until the last moment, and in the meantime Rosetta is a high definition image of the comet surface We are planning to do a one-time mission to shoot and send to the earth.
