"The medical staff is very hard. I've been in the quarantine area, and I haven't seen my family anymore," mentioned the situation here, and the person in charge of the hospital also said with some emotion.

"We can help with that." Fan Wuxian nodded.

Then he instructed the person in charge of the Guangzhou branch to immediately contact and mobilize a batch of laptops to come over, requiring them to be equipped with video heads and microphones, and at the same time set up several wireless hotspots in the quarantine area that can access the Internet, so that the medical staff can make video and calls with their families at any time.

"Thank you so much." Hospitals and research institutes expressed their gratitude.

After leaving here, Fan Wuxian returned to the hotel and collected the current information on the Internet. There are now reports on the addition of non-cars. It didn't attract everyone's attention, and I couldn't help but shake my head.

It's a bit tricky to think about, and the average news media unit is reluctant to report on this kind of thing, especially when the government changes in a month, and no one wants to cause chaos at this time.

There is another thing that has been hyped up on the Internet, that is, on the day of the Spring Festival, the Columbia space shuttle of the United States suddenly crashed.

The cause of the crash of Columbia is not yet certain, but according to the head of NASA's space shuttle program, Columbia has been operating normally since its launch on January 16. At 8:53 a.m. EST on Feb. 1, NASA suddenly received the first signal of a space shuttle malfunction, when the temperature sensor data transmission of the shuttle's left-wing hydraulic system was abruptly interrupted.

Immediately after that, the space shuttle tire pressure data also disappeared suddenly, and the space shuttle also had a structural overheating situation.

At that time, the space shuttle Columbia was about to re-enter the atmosphere, the fuselage was under high temperature pressure, the wings were already hot at 3,000 degrees Fahrenheit, and the plane was operating at 125000 miles per hour, which is 18 times the sound of sound.

NASA's control center lost contact and tracking of Columbia at 9 a.m. ET when the shuttle was flying at an altitude of 62,000 kilometers over the U.S. state of Texas. Since then, NASA control has not received any communication or tracking information about the Space Shuttle.

The crash of the space shuttle Columbia caused great shock and grief throughout the United States, and US President George W. Bush, who was spending the weekend at Camp David, hurried back to Washington after receiving a report from White House Chief of Staff Kad and held an emergency meeting with cabinet members on the circumstances of the space shuttle crash. He then spoke on the phone with the families of the dead astronauts. Condolences to the loss of the astronaut.

At two o'clock in the afternoon of the same day, US President George W. Bush, with a solemn face and a heavy heart, made a televised speech to the nation at the White House. After enumerating the names of the astronauts who were killed, Bush said that in an era when space flight was regarded as almost commonplace, it was easy to ignore the dangers of rocket travel and the difficulty of navigating in the extraterrestrial atmosphere. These astronauts understand these dangers, they are willing to face them, and they know that there is a higher purpose in life, thanks to their courage, boldness and ideals. We will miss them even more.

Bush stressed that the cause for which they sacrificed will continue, that humanity will be inspired by the present and thirst for knowledge into the darkness beyond our world, and that our journey into space will be

。

The leaders of China, Russia, France, Canada, and other countries sent messages of condolences to US President George W. Bush after the crash of the US space shuttle; while expressing deep condolences for the tragic death of the US astronaut, they also believed that mankind's efforts to explore space science would not be affected by this and would certainly continue to make progress.

What exactly was the cause of the space shuttle crash in Columbia?

In order to find out the cause of this accident. NASA Administrator has announced the appointment of a retired Commodore to chair an independent commission of inquiry, focusing on whether the detached insulation at the outer end of the plane's fuel tank damaged the shuttle and caused its eventual crash.

NASA said at a press conference on the day of the incident that Columbia was launched on the same day. The insulation at the outer end of the fuel tank was damaged and loosened, but it is not known if the insulation on it was damaged.

Due to the high long-term operation of the space flying pine. The temperature of the exterior of the fuselage, especially the wing parts, is very high, so the fuselage of the space shuttle needs to be protected by graphite insulation tiles to prevent damage caused by the body during high temperatures. If the thermal insulation tile near the oil tank falls off, it may cause the shuttle to explode or disintegrate in the air.

The next day, there was a new development in the investigation into the cause of the accident, and the members of the independent investigation committee, after analyzing a large number of aircraft wreckage fragments and computer data collected from Texas and Louisiana, concluded that the left side of the shuttle's fuselage had risen sharply before its disintegration, and that the left side of the shuttle was the side where the body was damaged when it took off on 16 January.

Some US experts have pointed out with regard to the crash of the space shuttle Columbia that due to the decline in the budget of the space industry in recent years, most of these space shuttles that are 10 to 18 years old have not been upgraded and maintained, so as to improve flight safety

The crash of the space shuttle Columbia will have a certain degree of impact on the US space industry. First, NASA has ordered a moratorium on all space shuttle flights, which will affect the implementation of many important space exploration programs in the next two to three years.

In addition, the crash of the space shuttle Columbia will lead to personnel changes within NASA. As a result, there are certain variables in the US space regulations that are difficult to predict.

There are also experts who believe that since the United States has decided to suspend all space shuttle flight programs. This will have a major impact on the construction of the International Space Station, which was originally planned to deliver a large amount of equipment and materials to the station for expansion by the Space Shuttle, and if the US Space Shuttle is grounded for a long time, the construction of the space station will certainly be negatively affected.

When Fan Wuxian checked on the Internet, Shen Ying and Cui Qi were resting in the house, and the two chatted for a while, and then came to see what Fan Wuxian was doing, and now he was watching the news about the crash of the Columbia.

Zhangqi also saw this topic, and couldn't help but say to them, "I remember that my predecessors stood on the ancient battlefield of the Battle of Roboponnese, and once said that the whole earth is the graveyard of great men, and the endless flow of time is their glorious celebration." A slight modification of this statement can be quite appropriate to evaluate this matter, and the whole day is empty as the graveyard of great warriors, and the endless flow of time is their glorious celebration. ”

Fan Wuxian nodded, space exploration is the common cause of all mankind, although the positions are different, each has its own national interests, but in this matter. The spirit of exploration of all human beings coexists.

The U.S. space shuttle Columbia disintegrated sixteen minutes before it was expected to land, killing all seven astronauts. At that time, the shuttle was at an altitude of 203,000 feet, flying at 12,500 miles per hour, enduring temperatures of more than 3,000 degrees, waiting to make contact with the ancient and benevolent earth again after taking off on January 16.

However, communication was abruptly interrupted, and debris burst into the sky like fireworks. Tragedy always comes without warning. Creation is always unpredictable. There is reason to believe that the seven astronauts did not even have time to eject the rescue capsule before they were engulfed in the fire and finally disappeared into the blue sky of Texas.

This is reminiscent of the famous pillar of smoke left in the sky by the space shuttle Challenger on January 28, 17 years ago, as if it had been struck by thunder, and there seemed to be the fury of the creature after being offended.

Fan Wuxian has not been in close contact with the space shuttle, but when he is in contact with the large strategic transport aircraft, he can appreciate the similar style a little, when you look up at the steel giant overhead, the neat chatting nails and smooth wing body make people really feel the activity of human intelligence, it looks so powerful, because humans make steel fly in the air.

However, he is also well aware of the fragility of this artificial machine, compared to the great nature, the steel beast flying in the atmosphere is just a leaf in the ocean, and human beings are just ants driving this leaf to see the other side of the sea.

"In the face of the unknown space, we are of course ants, ants who keep climbing on the edge of grass leaves. With the courage of this exploration, we can see the size of a football field. Isn't this a great achievement in our small and fragile bodies? Although we may not know anything about the stands of the 100,000 people around us, although we may be smashed to pieces by the sudden football, Fan Wuxian couldn't help but say with some emotion. "Looking up at the vast starry sky is like an ant gazing at an endless lawn. When human beings fly small spacecraft of their own creation, shuttling between space and the earth. When gazing with the blue sea and the daily line that alternates between yin and yang on the horizon, who can say that this small and fragile group of human beings is not a great warrior? ”

Through their efforts, human beings have traveled through the ancient flood era, conquered the fierce mother and the saber-toothed tiger that are a hundred times more powerful, built a city-state on the earth that nature has never had, and traveled through the world in a boat that the creator did not know.

Unable to limit humanity from the ground, they will seek new answers, explore the mysteries of time and space, ask if there is an eternal fire burning, whether life is a reciprocating tide.

"No one would mind paying the most respect to these warriors, whether they succeeded or failed. Maybe it's not the success, it's the countless failures that light up the eternal night. The road sign leading to the oasis is a snow-white skeleton on the side of the road. Therefore we arranged their graves in the sky and laid their names with the stars. With endless time as their incomparably glorious celebration, with our inquiring eyes, to be their eternal witness. Fan Wuxian sighed as if chanting, "They slipped through the fetters of the other side of the sky. Touch God's cheek. ”

When he looked back, he saw that Shen Ying and Cui Qi were both looking at him in a daze, so Fan Wuxian explained, "Don't be surprised, I didn't write it, I just read it aloud with feelings."

"Today's third shift to one one by one, one by one Sichuan (to be continued) Jian Shu dry plus concave Shan) different body clams, read good to go outside on the cat pounce no pop-up window
