5 greatest scientific achievements in NASA history

For over 50 years, NASA is still trying to find the answer to the mysteries of the universe. With many unbelievable miracles, humanity, when looking back at NASA's greatest scientific achievements, will feel proud.

NASA and the greatest scientific achievements in history

1. Chandra X-ray telescope

The Chandra telescope was launched into the second half of 1999 and is an important device in NASA's space conquest. During fifteen years of operation, Chandra has provided mankind with a unique panoramic view of the universe. This is considered one of the greatest scientific achievements in NASA's history.

The Chandra X-ray telescope has an elliptical orbit around the Earth, providing astronomers with a better view of the high energy density concentration areas in the universe or places that might be the remains of a supernova explosion. Chandra's images have helped scientists better understand cosmic pulses (pulsars, forms of electromagnetic radiation associated with the formation and death of stars) and nebulae in the universe.

Chandra is considered one of the four "great observatories " of NASA , the other three names are the Spitzer Space telescope, the Hubble space telescope and the Compton Gamma Ray observatory.

2. Freedom 7 and the mission of bringing the first Americans into space

On 5 May 1961, Alan Shepard left Earth and officially became the first American astronaut to fly into space . It should be noted that Shepard was not the first person to fly into space - the great achievement of the great Soviet astronaut Yuri Gagarin.

The historic mission of bringing the first American to space was successfully implemented in 1961

In fact, the time Alan Shepard flew into space just after Gargarin's flight was exactly 23 days. And from that moment, Shepard wrote his name on NASA's great chronicle with the first manned flight into space and set the standard for astronauts to follow his path later. . Shepard left Earth at 09:34 on the Freedom 7, his historic flight lasting a total of 15 minutes and 28 seconds.

3. ISS International Space Station

The International Space Station ISS was built in 1998 and put into use by researchers since 2000. The first crew arrived in the station in 2000 and since then they have lived in the place. Here, serving for research and space exploration.

NASA and its partners from all over the world formally completed the construction of the International Space Station in 2011. Astronomers had to study to find ways to live in a zero gravity environment, and beyond that is to accomplish the future task of bringing people to the Moon and Mars.

Referring to NASA's impressive scientific achievements, it is impossible not to mention the International Space Station ISS

The image of the International Space Station ISS is a concrete testament to the claim that missions in space can bring incredible results. Although the International Space Station (ISS) is not the first human space station, it is undoubtedly the most impressive space station.

4. Apollo 13

On April 11, 1970, the Apollo 13 spacecraft was launched, and after 55 hours and 55 minutes, a devastating explosion occurred , destroying almost the entire system as well as the equipment needed to maintain. life on board.

The horrifying incident began because one of the ship's engines stopped operating within two minutes of takeoff. One of the two oxygen tanks exploded and the pressure of the explosion caused the second oxygen tank to continue to break. Soon after, two of the spacecraft's three fuel chambers stopped working. This means that all of Apollo 13's oxygen storage has leaked into space and all basic life support such as electricity, water, light, temperature and oxygen ends.

This disaster marked one of the best collective rescue phases in human history. People had thought about the tragic possibilities that could happen but in the end the miracle came, the survival of crews James Lovell, Fred Hayes and John Swirget were considered a miracle.

The courage and bravery of the men on the ship and all those involved in the rescue mission is a typical demonstration of the extraordinary intelligence and courage of mankind.To maintain life, astronauts have almost no food, no water and no sleep while the temperature on the ship is close to freezing. In less than six days, crew members lost 31.5 pounds because of dehydration.

While they were patiently waiting, NASA technicians at the control center tried to work relentlessly, eventually after thousands of days completing thousands of algorithms and choosing solutions. They found a way to save the astronauts back.

5. Apollo 11

Apollo 1 was originally expected to be the first manned space shuttle to land on the Moon but unfortunately, the spacecraft did not fulfill that noble mission. The ship test was a real disaster, killing all three astronauts due to a fire in the cabin.

Apollo 11 put Neil Armstrong on the Moon as a great scientific achievement for NASA

Two years later, NASA ran a total of 9 experiments with a series of space shuttle projects. Finally, the submarine of Apollo 11 became the first mission to successfully bring people to the Moon . When Neil Armstrong astronauts set foot on the surface of the Moon and uttered the legendary saying "A small footstep of man, a giant leap for humanity" , the whole world was amazed, even some people are skeptical and do not believe in miracles.

Soon after, Buzz Aldrin and two others became the next to set foot on the Moon. Since Apollo 11's mission has been successful, only ten astronauts have ever set foot on the Earth's only natural satellite.
