The most important tasks in NASA history (Part 1)

Since the US National Aeronautics and Space Agency (NASA) was founded more than half a century ago, they have carried out hundreds of missions in space , from pushing exploration devices into space and access to the outer planets of the Solar System, to send manned capsule caps into space .

Some of the most important advances in science, technology, engineering and mathematics have been made as a direct result of these tasks. Some of the most important and interesting tasks that NASA has ever done are as follows.

WMAP satellite

Did you know that humanity has a picture of the early universe? In fact, we can't get any image from the moment of the Big Bang Big Bang. In the first few hundred thousand years of the cosmic life, everything was so hot and so close, that photons could not reach anywhere. In any direction, only a few light years can be seen, until the giant hydrogen clouds fill the universe, making it even more impossible to see.

This satellite was launched on June 30, 2001.

However, after about 380,000 years, everything cooled and spread. The first light was able to escape. This light from the beginning of the universe went to Earth from all directions in the sky. It shows us the universe at its earliest stages and is called cosmic microwave background radiation, or cosmic remnant radiation (CMB). In other words, this is the type of radiation generated from the early days of the universe, whose spectrum is similar in shape to the radiation spectrum of black matter, with the peak within the microwave wavelength range (ranging from a few millimeters to a few tens of cm). Most cosmologists believe that cosmic background radiation along with redshift are the best evidence to prove the correctness of the Big Bang model of the universe.

Since discovering this, scientists have wanted to map out the hot and cold spots of CMB to see if they match the experts' predictions. That data did not exist until several decades ago. Even then, it was not released, until NASA's anisotropic Wilkinson satellite (WMAP) proved that scientists had a pretty good HD image of radiation. The results from the polls are consistent with the prediction and confirm that the universe is almost completely uniform in temperature at more than 14 billion years ago. It's great when we gather information about something that has been around for a long time.

This satellite was launched on June 30, 2001. In April 2002, WMAP completed the first observation of CMB. In February 2003, the first high-resolution images of CMB and results analysis papers were published. WMAP's research materials are one of the most used and cited documents in the history of space science.

The only information about the transfer is recorded when the transaction takes place. In fact, only about 10% of transactions on Zcash use the 'hidden' option , because with this option, more computer time and energy is needed to handle the necessary calculations.

Viking I and II ships

Before 1976, the United States had never succeeded in conducting a poll on another planet. Similar projects often fail, while millions of dollars worth of machines sent to 'Red planet' tend to be hit on the planets' surfaces during space travel. speed thousands of miles an hour.

Titan IIIE / Centaur missiles deployed two Viking probes and sent them to different orbits.

Getting an object to orbit to orbit the Earth was extremely difficult, but getting a spacecraft to leave Earth's orbit, orbiting around another object, and then landing success on that planet is a huge challenge. However, this technical feat was done by Viking probes.

Within a month, the Titan IIIE / Centaur rocket deployed two probes and sent them to different orbits. Part of the probe is left in orbit around Mars, and another part lands on the planet's surface.

Based on what is observed from Earth, scientists think life cannot exist on Mars. However, humans have never been there to assert these assumptions. This problem has been proven as soon as Viking probes send back the first images and test results to NASA. The probes found no evidence of green 'Mars' , or any microbial life.

Friendship Train 7

As of early 1962, the United States had just over 30 minutes of experience in space, while the countdown timer to the end of the decade was marked. The US has never sent people into Earth orbit - an extremely important part of bringing people to the Moon and defeating the Soviet Union. All changed with the launch of Friendship 7 , the third mission of the US Mercury.

Lieutenant Colonel John Glenn - who was chosen to control the new Atlas rocket into orbit around the Earth.

Lieutenant Colonel John Glenn , a military test pilot, was chosen to control the new Atlas rocket into orbit around the Earth. The rocket took off on February 20, 1962, successfully penetrating Earth's orbit for nearly five hours. He landed safely about 1,300km south of Bermuda.

The goal of the mission is to test new missiles, learn to spin around the Earth, and prove that humans can exist and function in space.

Mercury Seven is a group of seven astronauts of Mercury published by NASA on April 9, 1959. They were also known as the Seven Groups or the original Astronaut Group 1, which was tasked with piloting Mercury's manned spaces from May 1961 to May 1963. These seven American astronauts are Scott Carpenter, Gordon Cooper, John Glenn, Gus Grissom, Wally Schirra, Alan Shepard and Deke Slayton.

Members of the group practiced flying all over NASA's manned spacecraft in the 20th century - Mercury, Gemini, Apollo and space shuttle Space. Gus Grissom died in 1967, during the Apollo 1 fire. John Glenn continued to become US Senator and flew on a space shuttle for 36 years, then became the oldest person flying in space. He died in 2016, at the age of 95.
