The success of Neil Armstrong to land on the Moon is indeed an unforgettable momentum that continues to be discussed to this day. Some even discussed it as a debate as to whether it really happened and most people thought only Neil Armstrong, Buzz Aldrin, and Michael Collins ever reached the Moon that triggered the question of why there were no more humans on the Moon after them.
In fact, the Moon landing was not just once when the Apollo 11 mission landed on the Moon on July 16, 1969. After the Apollo 11 mission, there was still 6 manned missions in Apollo Apollo (Apollo 17) mission that departed to the Moon.
All Apollo missions after Apollo 11 except the Apollo 13 mission successfully landed humans in various areas of the Moon and took home rock samples just like Apollo 11.
The mission of Apollo 13 in 1970 suffered a failure on the way to the Moon due to an explosion of oxygen tanks that paralyzed the spacecraft propulsion as well as paralyzing the life supporters of the rides. The astronauts who took part in the mission then used the Lunar Module as a "lifeboat" to replace the paralyzed function in order to return to Earth.
Noted there are 12 people who have landed on the Moon. In each mission, there are 3 crew members who departed but in each landing only 2 crew who set foot on the Moon while 1 other crew remained in Space Ranges that continue to orbit the Moon.
The success of the Apollo 11 mission landed on the Moon for the first time. beginning with other pilot missions.
The Mission to the Moon does have a strong political link in terms of competition between the Soviet Union and the United States. The exploration of the Moon was marked by the success of the Soviet Union's Luna 2 impactor arriving on the Moon on September 14, 1959, and crashing into the Moon's surface. Before Luna 2 there had been 5 Luna-owned Luna impactor and 5 NASA's Pioneer orbit that had failed.
For manned missions prior to the success of Apollo 11 missions, NASA also conducted many trials by sending orbiter and unmanned missions as a first step before landing humans on the Moon. Six unmanned missions related to the Apollo mission departed from 1966 - 1968, followed by a manned mission that began in the Apollo 7 mission to orbit humans on Earth, then the Apollo 8 mission became the first human mission to fly to the Moon. The successful manned mission landed humans on the new Moon successfully on the Apollo 11 mission that landed Neil Armstrong and Buzz Aldrin in the Sea of Tranquility, the Moon. And the Apollo 17 mission, which is the last manned mission, also marks the geologist's presence on the Moon for the first time.
Since then the manned mission to the Moon has ceased to exist because of a much larger funding problem than an unmanned mission capable of performing the same task. But dreams and hopes of returning to the Moon are always there. In the modern era, NASA is not the only one who wants to return to the Moon. Recorded countries such as India, China, the European Union, Japan, Iran, and Russia are also preparing their manned missions to the Moon for the year 2015 - 2027.
Impactor and Orbiter to the Moon are still being sent and now not only America but from China, India, and Japan. Noted, South Korea is also preparing their mission to the Moon. While missions to the moon are canceled also exist as a result of the absence of funds or funds rejected by the Congress.
So the dynamics of sending manned missions to the Moon is actually not on technology but on funds that are willing to be disbursed by a country to deliver its mission. And if anyone asks the countries that prepare for the mission is rich, why can the fund not exist? This is not just a matter of money or not, but rather a country's priority in terms of the use of funds.
For example, it is not possible Egypt even if for example have a lot of money then prefer to build a mission to the Moon and even displaced millions of its starving population. The same is true of countries developing a space mission. Choosing between unmanned or unmanned missions with the same results but funding a single manned mission can be used for some unmanned missions. Then on the scale of the donor, the state will think whether the space mission is the main focus or economic issues, security, etc. That is all and thank you!
