On April 18, 2022, Russian cosmonauts Oleg Artemyev and Denis Matveev on the International Space Station performed a spacewalk lasting 6 hours and 37 minutes.
The spacewalk is significant, it is Artemiev's fourth spacewalk, Matveev's fourth spacewalk, the fourth spacewalk of the International Space Station in 2022, and the 249th spacewalk to assemble, maintain and upgrade the International Space Station.
They successfully installed a control panel in the Russian science experiment module, which will be used to connect the 37-foot-long European robotic arm, and they also removed the European robotic arm protective cover and installed a handrail on the outer wall of the scientific experiment module to facilitate astronauts to carry spacewalks and payloads through the robotic arm.
Despite the deterioration of Russia and the United States, the most severe economic sanctions ever imposed on Russia by the United States, and the announcement of the suspension of cooperation with the United States on the International Space Station, the United States Space Agency (NASA) is still very concerned about the Spacewalk of Russian astronauts and broadcast the whole process live.
Suddenly a small white object appears
Scott C. Walling, a self-described UFO expert, said he suddenly spotted an "alien spacecraft" through video footage provided by NASA, and the so-called "alien spacecraft" kept a certain distance from the International Space Station so as not to frighten astronauts. So, is this true?
According to the video footage shown by Scott C. Walling, behind the solar wing of the science experiment module, a "small white object" was indeed displayed, which was hanging above the Earth's atmosphere, so far away from the International Space Station that we could not know its actual shape and actual size.
Although the universe is vast, it is still unknown whether there is a highly intelligent alien life, but one thing we can be sure of is that so far, I have not found any clues to the existence of aliens, so it is absurd to regard the blurred "small white objects" in the video screen as alien spacecraft.
So, what could be a "small white object" floating in space? Let's take a closer look at it with a rigorous approach.
Is it the moon?
We look at it from the video footage, the light is shining from the left to the right, which can be seen from the lighting of the solar wing of the Russian science experiment module, and the left side of the small white object seems to be very bright, the edge part is spherical, and the right edge part is vertical, so it is indeed possible that it is the moon, and this possibility cannot be ruled out.
In fact, the International Space Station astronauts have repeatedly photographed the moon, such as the moon shown in the following image, which is much clearer than what is seen on Earth, because there is very little dust in space and almost no gas molecules at an altitude of 400 kilometers.
Are they artificial satellites and space debris?
In Earth's low Earth orbit, there are nearly 6,000 controlled artificial satellites, and thousands of uncontrolled abandoned satellites, in addition to artificial satellites, there are also a large number of space debris flying in low Earth orbit, so is it possible that the "small white objects" are artificial satellites and space debris?
In fact, this possibility is not very likely, because abandoned satellites and larger space debris are tracked by trackers on the ground, it is absolutely not allowed to approach the International Space Station, in order to avoid space debris, the International Space Station has to change orbit several times a year, so the "white small object" should not be artificial satellites and space debris.
Are they small pieces of debris in front of the camera?
It is not the first time that strange objects have been photographed near the International Space Station, and astronauts are not strange, for these strange objects, astronauts have long explained to the outside world, these seemingly distant blurry objects are actually a small debris in front of the camera.
A fine speck of dust, or a piece of dandruff, when they float in front of the camera lens, because of the visual relationship of the human eye, people can easily see it as a distant blurry object, and astronauts have explained many times with small debris that people suspect that it is an unknown object that is a UFO. Therefore, the possibility that a "small white object" is a fine debris is extremely high.
At last
On April 18, the "small white object" shown by the International Space Station astronauts in the spacewalk video could not be an alien spacecraft, and its identity had two possibilities, one could be the moon in the distance, separated by the Earth's atmosphere, which did not look very clear, and the other could be the small debris in front of the camera.
