000, Artemis 1 in the United States was successfully launched, and humans were one step closer to the moon!
International Student Daily , like 203
Artemis 1 was launched at around 14:50 Beijing time on November 16 (1:50 am Eastern Time on November 16), and was launched on the Kennedy Space Center LC-39B platform, with the launch window for 2 hours .
This time the moon-orbiting test is not manned, and it is mainly for Artemis 2 manned orbiting the moon and Artemis 3 manned landing on the moon.
is used as a zero gravity indicator. In addition to NASA mascot Snoopy, ESA also placed the Sheep Sean doll inside the "Orion" spacecraft , preparing to carry out the "Artemis 1" mission together.
Artemis 1 Mission duration is 25 days 11 hours 36 minutes ,
If it can be launched smoothly today, Orion spacecraft is expected to splash and fall on the San Diego coast on December 11, 2022. 's entire voyage is about 2.1 million kilometers .
After experiencing multiple fuel leaks, NASA finally successfully completed the fuel test of SLS. Artemis 1 was about to be launched.
accidentally encountered hurricane transit. The launch window from September 23 to September 27 was not guaranteed and could only continue to be postponed.
finally ushered in this November launch window.
If everything goes well, this will be the next time that humans will move towards the moon 50 years later .
01. What is SLS?
"Space Launch System" (SLS) is the most powerful launch vehicle in NASA's history. It is part of NASA's lunar landing project, "Artemis" project, and is expected to send astronauts to the moon as early as 2025.
NASA has been brewing for more than ten years for the moment of returning to the moon.
SLS is ready for the long-awaited first flight mission, Artemis 1.

In August this year, the $4.1 billion SLS heavy rocket slowly drove out of the Kennedy Space Center launch vehicle amid the cheers of hundreds of space center staff and families.
After 4.2 miles of nightly vertical transportation, it arrived at the 39B launch pad.
It is reported that due to the thunderstorm nearby, the trip was delayed by about an hour, and the Rockets completed the transfer on the same day.

When the mobile launch device lands on the base on the top of the launch pad, the engineers will connect power, data, propellant pipelines, waterlines and other systems to prepare for a comprehensive pre-launch test and inspection of the rocket.
is the last time this SLS rocket has been launched into the factory, and this time it is really here.

If everything goes smoothly as planned,
This rocket will start its first flight in 42 days, orbiting the moon and returning.

02. Is there any real person in this launch?
capsule will be carried by 3 fake "astronauts" - 3 human models equipped with instruments.

The goal of the "Artemis 1" mission is to verify the performance of the SLS, test the solar-powered "Orion" astronaut capsule in deep space, and confirm that its 16.5-foot-wide insulation panel can safely protect the spacecraft at the end of the flight, causing it to fall into the Earth's atmosphere at high speed.
If the test flight progresses smoothly, NASA plans to launch the second flight of the SLS rocket in 2024, namely Artemis 2.
Artemis 2 will carry four astronauts, and in the third flight mission within 2025-26, the first female astronaut and the next male astronaut will be sent to the surface of the moon.
According to " Science ", although SLS was not live on when it was launched this year, there will be 10 "cube small satellites" flying into the sky together.
Each satellite is about the size of a briefcase and can be used to detect the moon (several cube satellites will focus on lunar ice), asteroids and deep space radiation environments.
Facing the launch day in just over a dozen days, the US NASA satellite manufacturing personnel expressed their concerns.
These satellites have been stuck in the rocket for more than a year due to launch delays, and their battery may be about to run out.
There are about half of the satellites that have . It may not start and expand solar panel , so it cannot charge .
The problem is, "The longer the waiting time caused by the launch delay, the greater the risk." Ben Malphrus, chief researcher at
Lunar Observation small satellite (one of 10 cube satellites), and said from , Moheide State University in the United States.
This is the beginning of the ten-year plan for the US NASA to re-land on the moon.
1969-1974, Nixon ushered in the most glorious stage of the "Apollo Project". On July 16, 1969, Apollo 11 landed successfully on the moon.

Apollo 11 is the fifth manned mission in NASA's Apollo program. is the first human lunar landing mission , which lasted 8 days, 13 hours, 18 minutes, 35 seconds, orbiting the moon for 30 weeks, and staying on the lunar surface for 21 hours, 36 minutes and 20 seconds.
The three astronauts who performed this mission are commander Neil Armstrong, command module pilot Michael Collins and Lunar Module pilot Buzz Aldrin.
In 1967, when the Apollo project began, it encountered disadvantages.
Apollo 1 was originally scheduled to be launched on February 21, 1967.
However, in a routine test on January 27, a fire broke out in the command module and three astronauts unfortunately died within 15 seconds. These include Edward White , which was the first spacewalk, and was only 37 years old when he was killed.

On October 11, 1968, Apollo 7 was successfully launched, which took eleven days to complete the orbital flight test. This is also the first manned mission in Apollo's plan.
At 9:32 on July 16, 1969, Apollo 11 carried astronauts Neil Armstrong, Michael Collins and Buzz Aldrin and launched at the Kennedy Space Center.
After returning, in order to ensure that the astronauts did not get infected with unknown diseases on the moon, the three of them were quarantined for 18 days after landing.

However, Apollo 13 , which followed closely behind, encountered an accident.
Apollo 13, launched on April 11, 1970, occurred before arriving on the moon, and the oxygen tank exploded. Both electricity and oxygen were lost greatly. The moon landing plan was forced to give up.
But fortunately, under the guidance of 150 scientists and engineers from the Control Center, three astronauts who were stranded in space for 715 hours returned successfully.
Astronaut Lovell solved the corresponding problems in the cabin according to ground instructions
On January 31, 1971, Apollo 14 was successfully launched, completing the task that Apollo 13 failed to complete.
On December 7, 1972, Apollo 17 was successfully launched. This is the last successful landing of the moon so far .
No matter what, as generations grow old, human beings have never set foot on the moon again in the next 50 years.
, and there are only 4 people left in the 12 astronauts who have set foot on the land of the moon.
The first person who landed on the moon, Armstrong, is famous for his seclusion. He died in 2012 at the age of 82.
Alan Bean, who painted with oil paint mixed with lunar soil, became a painter after retirement. He always had only one theme of painting - the moon scenery he saw with his own eyes. Bean died at home in 2017 at the age of 86.

Moon lander Pete Conrad died in 1999 in a motorcycle accident in California at the age of 69.

Apollo 14 member Alan Shepard After retirement, he continued to engage in banking and real estate business and served on the non-profit board of directors. He died of leukemia in 1998 at the age of 74.
, John Young, who retired in 2004 and worked at NASA for more than 40 years, passed away in January 2018 at the age of 87.

No matter which country it is, for the same aviation dream, they have paid not only time, money, and even life...
50 years ago today, the United States launched the "Apollo 17" Saturn 5 heavy rocket to complete the wet rehearsal;
Today, the United States carried out the "Artemis 1" mission SLS heavy rocket.
After more than 50 years, can humanity's footprints move onto the moon again?
When humans start their journey to land on the moon again, in addition to the United States, China is also steadily advancing its own moon landing plan, planning to achieve manned moon landing by 2030.
's exploration of the universe, especially the massive moon landing plan, although it is usually a stage for showing national strength among major powers, it is also a reflection of the technological progress of all mankind.
This time, there was a Chinese seat in the moon landing competition.
Come on China, come on humanity!
