Apollo 1 - planned start on February 21, 1967; Astronauts Virgil Grissom, Edward White and Robert Chaffee were performing the final tests the Saturn 1B on January 27, 1967 and they all burned. Additionally, they were awarded a honorary rank Apollo 1, although it was the third in Apollo in chronological order.

Apollo 2 through Apollo 6 - were also the test flights without crews. When launching Apollo 6, the rocket Saturn 5 was used for the first time, but had big problems at the start.

Apollo 7 - started October 11, 1968, Saturn 1B rocket, crew Walter Schirra, Don Eisele and Walter Cunningham. The crew completed a flight around the earth, theym made the first black and white television coverage and performed six scientific experiments. EA Cernan was a substitute pilot of this crew, which meant that he would be participating in the Apollo mission 10.

Apollo 8 – started on December 21, 1968, the flight lasted for 6 days, Saturn 5 rocket was used, and the crew consisted of Frank Barman, James Lovell and William Anders. They completed the first orbit of the Moon and took pictures of the Moon and the Earth.

Apollo 9 – started on March 3, 1969, the flight lasted for 10 days, the Saturn 5 rocket was used, the crew consisted of James Mc Divitt, Russell Schweickart and David Scott. They orbited the Earth twenty times.

Apollo 10 – started on May 18, 1969, the flight lasted 8 days, the Saturn 5 rocket was used, the crew Thomas Stafford, John Young and Eugene A. Cernan. Apollo 10, the ship got on the Earth´s orbit in less than one and a half minute at a height of about 185 km. After the planned orbits, the crew switched on the third-level motor, increased the speed to about 40,000 km / h and started approaching the moon.

EA Cernan described the journey of other people to the Moon´s proximity as follows:

When I looked back to the Earth, I saw only a distant blue and white star. The place we were rushing into was welcoming us with just stars and distant eternal darkness of the infinite space. We left the area of gravity on May 21, and from that moment we began to be attracted by the moon. When we got in its orbit, we were nestling against the windows and observing the grey country running past below us. We were quietly watching the wrinkled mountains and valleys, ridges and ravines. We were looking at the mountains, maybe extinguished volcanoes, which were white from the outside and black inside. Some small craters were of the size of a football pitch, others might have been on average fifty kilometres in diameter.

At the same time and for the first time in our lives, we caught a glimpse of the Earth rise on the curved moon horizon. It was an amazing scene! We watched our planet gradually emerging: its colours sharply contrasting with the darkness of the universe. We were looking for a suitable place of landing for the crew of Apollo 11. We found a relatively convenient surface (The Sea of Peace- note by the Author) that resembled a dried-up riverbed. We tried our landing radar and we were searching for the traces of underground magnetism that could confuse the navigation system. We even did not notice and suddenly, it was time to go. The return flight started and on 26 May 1969, we landed in the Pacific Ocean where we were being waited for by the boat called Princeton.

After their return to the Earth, the crew of Apollo 10 was welcomed by America as heroes. EA Cernan who was fulfilled by the admiration of his fellow citizens wondered how he would be welcome by his family back at home – by his wife and especially by his 6-year-old daughter Theresa (Tracy). When he appeared at the door, she threw herself into his arms and hugged him around the neck and asked, "Daddy, when are we going fishing?" This was the moment he realized the value of his deeds. Everything he did and everything he accomplished for a child soul.
