In 2021, unusual space news was a year in the past.Let's look back in the photo

It was 2021, when the International Space Station was idle, satellites were hit by space garbage, and there were many problems in the universe.

Aiming to aim for space with a rocket a long time ago, it was a dream story, but now the cost is getting lower and the civilian has a spacecraft ticket.The number of rockets that is fired, the number of satellites that go around the earth, and the amount of space garbage are increasing, and ridiculous troubles are continuing in outer space.

This year, the U.S. gis mode summarizes what humans have done in space, so please click below!

International Space Station, spinning

The largest pinch of the International Space Station has been visited on July 19 this year.When the Russian multipurpose experimental module "Naoka" docked, the thruster was malfunctioned and there was a trouble in which the space station turned back 540 degrees backwards.

Russian flight control tried hard to control in the fear that continues to rotate and converges 47 minutes later.However, it stopped just upside down, so it was necessary to rotate 180 degrees positively.

According to Russia, the cause was a software bug.NASA explained that it was not a problem related to the life of 65 astronauts at the time at the time, but if the rotation speed was faster, the space station would not have been damaged.It may have been spinned so that he could not put on the worst.

By the way, in October, Russian Soyuz Capsules caused similar slaster problems and rotated the International Space Station 60 degrees.

King Amazon, Bezos, sue NASA

The United States, which aims to fly to the moon in the "Artemis 3" mission, recruits the concept of a lunar landing ship from six private companies (blue origin, lockhid Martin, Northlop Gruman, Drainer, Dynetics, Space X).As a result of judging, 28 to Space X.I ordered a 900 million dollar contract.However, Jeff Bezos, who was angry at this, led Blue Origin.He took his opponent with NASA to his complaint.

According to Bezos, NASA had promised a number of private contracts for Blue Origin.In addition, the lunar landing system proposed by Space X also complained that "flight safety standards are being ignored."

The United States claimed Court of the United States ultimately dismissed Bezos's appeal, but in this case, the "Artemis 3" mission was significantly delayed.This is because during the seven months of trial, the development of Space X's manned landing system (Human Landing System) has been stopped.Although the development has resumed, the mission scheduled for 2024 is expected to be postponed after 2025.

The largest artificial falling object in history

On April 29, the core stage (total length of 30 meters) of China's Chang No. 5 accidentally invaded the low circumference of the earth.It became impossible to control and re -enter the atmosphere a few days later, and there is a possibility that it will fall into the densely populated area!Experts tried to track, but they could not identify the falling point, and on May 9, they fell to the Indian Ocean and got nothing.

In response, NASA criticized China, saying, "We have not fulfilled enough responsibility for its own space garbage."With a weight of 23 tons, it was the largest one in history.

Space toilet problem

In September this year, the first all -civilian mission, which was called "Inspiration 4", went on a space trip on a Space X Crew Dragon Ship.It was all right, but it was a toilet problem that only one of the crew members was made.

There is an alarm sound that tells you that there is something that is "serious" but an unstable problem, and the fun mood has changed completely.Nevertheless, the crew members of inspiration 4 did not lose their calmness, and when they consulted with the ground control, the cause of the alarm was threatened.It turned out that it was a fan who put together so that it would not be scattered, and it eventually came to a solution.

Later, Space X's Elon Musk tweeted to improve the toilet of the crew dragon ship.Space X also provided more information, and the urine could not reach the tank because the tube that led to the urine tank was removed.Although the same problem has been confirmed on the Crew Dragon Ship, Endeab, which was previously docked on the International Space Station, it has already been resolved, and the endurance of the crew dragon seems to have an upgraded toilet.

Starship during the test continues to arrive in a period of time → explosion

Speaking of SPACEX, the first half of this year was focused on the high -altitude flight test of the large spacecraft starship.

Starship with a total length of 50 meters 9.It is perfect to launch a 7 kilometer altitude, and the subsequent controlled aerodynamics are perfect.However, the final stage was not very good, and the prototype "SN9" had a big explosion when returning to the Bokachika launch pad on February 2, and the "SN10" landed on March 3.A few minutes later exploded.On March 30, "SN11" also experienced "unexpected rapid decomposition (in short explosion)".

So, on May 5th, when the "SN15" was successfully landed, Elon tweeted, "The landing of the starship is as planned!"Did the US Federal Aviation Bureau, who had been watching Space X, which repeatedly arrived, also stroked his chest?

A mysterious object synchronized with Chinese satellites

In early November, the U.S. Space Army discovered an apojikick motor, which was around the Chinese experimental satellite "practice 21".

An apojikic motor is a propulsion device used to put satellites on track, and is usually thrown away in the graveyard track when it is already used, but what was found is lined up with "practice 21".I was going around the ground synchronous orbit.The distance to the satellite was relatively close, and the movement seemed to be synchronized.

This situation, which is unlikely to be, has also emerged as "maybe it's just an appointed kick motor."Perhaps it is a sub -satellite with some function, but China has not disclosed this details.

Space garbage storm

Early in the morning on November 15, 2021, the crew of the International Space Station, which was still sleeping, was suddenly requested for emergency evacuation.This is because Russia destroyed its owned satellite "Cosmos No. 1408" using artificial satellite attack weapons (ASAT), and shattered satellite debris into a cosmic garbage cloud.

In this experiment, it is thought that space garbage with a diameter of 10 cm or more was 1,500 or more, and thousands of smaller and more difficult space garbage occurred.Fortunately, the International Space Station has escaped the damage, but the remnants of Cosmos 1408 will continue to threaten the safety of satellites and spaceships while going around the earth.

NASA accused the Russian satellite attack weapon experiment as "reckless acts", but in fact, the United States, China and India have performed similar experiments in the past.

Space garbage has continued to increase and "Kesler Syndrome" is also worried.Kesler Syndrome is the theory that "if the density of space debris (cosmic waste) in the orbit around the earth, the chain of collisions and destruction will explode and cannot develop space."From the dictionary).

In fact, Russian space garbage hits Chinese satellites directly, and fine space garbage has drilled a hole in the Canadian Arm 2 of the International Space Station.It is said that the arm is still functioning, but the satellite in China was a Buddha.

The location is space

This year was the first year when film shooting was performed in space for the first time in human history.

The location of the Russian movie "Vyzov" is an international space station.In early October, the starring actress Julia Precildo and the coach of Crim Sipenco entered the area and stayed in space for 12 days.

It seems that the surgeon, Zenya, was dispatched to the International Space Station and saved an astronaut who was ill, and Precildo won the role of Zenya in the audition.By the way, the shooting schedule seems to be severe, and immediately after returning from space, he performed in the Kazakhstan desert.No, it's too hard.

Captain Kirk, to space

Precildo was not the only actor who went to the universe.William Sutner, who played Captain Kirk in the Star Trek series, also entered space beyond the carman line.However, I stayed in space only a few minutes.

On October 13, Chartner enjoyed the space for a few minutes on a Blue Origin spaceship provided by Jeff Bezos.Despite the short time, Chatner looked down on the earth from space and was tears.

Unfortunately, Glen de Vrez, a businessman on the Blue Origin with Chatner, died in an airplane accident on November 11, after a space travel.

Boeing star liner, bugs are not eliminated

While Space X and Blue Origin made a breakthrough, Boeing was in 2021, which was in trouble.

Boeing's "CST-100 Starliner (Starliner)", which has been slightly delayed, has solved the problems pointed out by NASA, but the October launch test failed.When will it be possible to operate with customers?

In the launch test, 13 of the oxidant release valve of the propulsion system did not open, and it was postponed indefinitely.According to Boeing, it may have been due to the high humidity of Florida (the location of the Kennedy Space Center, which was tested).

As a Boeing, you would like to test track flight for the International Space Station in early 2022.I want you to work well.

Flying ban on millionaires

2021 was the year when the millionaires went on a space trip.The most riding was Richard Branson, the founder of Virgin Group.On July 11, he reached outer space on the VSS Unity, operated by his company's Virgin Galactic.

However, it was found that the pilot later ignored the warning lights that turned on.He seemed to be off the course on the way up 86km and flew in unacceptable airspace.Also, there was a danger that the descent and landing would go crazy if they did not go on the planned orbit.

The US Federal Aviation Bureau, which had a heavy situation, issued a flying order to Virgin Galactic and investigated.But since Virgin has since improved the problem, the ban has already been lifted in September.

The Russian module of the International Space Station continues to be in trouble

The Russian spaceship continued to be in trouble.In addition to the case where the International Space Station has been spinning due to the Naoka module sluster malfunction, a problem has occurred in the basic function module of the International Space Station launched in 1998.In August, Russian veteran officials pointed out that they were cracked in the Zero Module, and warned that "cracks will worsen on the days."

In September, the smoke detectors in the module worked, and the scorched smell of plastic drifted inside the ship.The reason was not disclosed, but it seems that it was consistent with the timing when the battery in the station was automatically charged.

It is said that Russian state -owned media spread the hoax that Russian state -owned media continued, saying, "In 2018, a NASA astronaut drilled a drill in the walls and za -module with a drill."However, Roscosmos has silenced it.

It is a series of events that are in danger of the future of the International Space Station, but what kind of development will be awaited in the future?
