On September 30, 2016, Rosetta, which had been in space for 12 and a half years, followed the footsteps of the lander Philae and landed on the surface of Comet 67p, because Rosetta was not originally designed for landing, and once it landed on the surface of the comet, it could no longer communicate with Earth, so the last of the captured images must be returned as soon as possible.
At 19:19 on September 30, the confirmation signal was suspended, since the 67p comet was 720 million kilometers away from Earth that day, the signal took 40 minutes to transmit back to Earth, and the landing time should be 18:39 on September 30.
18.1 km from the center of the comet, it was taken by a navigation camera (navcam) at 8:27 on September 30, each pixel is 1.5 meters, and the photo is about 1.6 km wide.
Located 16 kilometers from the surface of the comet, it was taken by a narrow-angle camera at 9:20 on September 30, each 30 centimeters per frame, and the photo is about 614 meters wide.
Located 15.5 kilometers from the surface of the comet, it was taken by a wide-angle camera at 10:17 on September 30, with 1.56 meters per pixel and a photo width of about 3.2 kilometers.
Located 11.7 km from the surface of the comet, it was taken by a narrow-angle camera at 13:25 on September 30, with 22 centimeters per pixel and a width of about 450 meters.
Located 8.9 km from the surface of the comet, it was taken by a narrow-angle camera at 14:53 on September 30, with 17 centimeters per pixel and a width of about 350 meters.
Located 5.8 km from the surface of the comet, it was taken by a narrow-angle camera at 16:18 on September 30, with 11 cm per pixel and a width of about 225 m.
Located 1.2 km from the surface of the comet, it was taken by a narrow-angle camera at 18:14 on September 30, at 2.3 cm per pixel and about 33 meters wide.
The last photograph sent back by Rosetta, taken by a wide-angle camera, is 20 meters above the surface of the comet, 5 mm per pixel, and about 2.4 meters wide.
During the descent, the comet pressure sensor (cops) instrument on Rosetta also recorded a rise in air pressure.
Compared to the signal of the Rosetta waking up from its slumber in January 2014, there is a clear difference.
The presence or absence of the Rosetta spacecraft's signal can be seen from the spectrum analyser at the Ground Control Center, which represents the carrier signal received by Earth's ground receiving station.
