The Acropolis    Athens, Greece


Visited the Acropolis and the Parthenon in 2003 and in 2019. Fascinating to visit the birthplace of democracy, 
with parts of buildings and ruins from 2,500 years ago. 


More photos from our Sabbatical 2003 when we took six months off and traveled around the world.







Pyramids and Sphinx in Egypt

The pyramids in Egypt were on the first Wonders of the World listed by the Greek historian Herodotus (484 – c. 425 BC). The Great pyramid of Egypt is the only one that still survives and it is top on our list.

Lesson to history - if you want your wonder to survive don't build a building - build a massive pyramid or mound too hard to move and to stable to fall down.

Apollo was the NASA program that resulted in American astronauts' making a total of 11 spaceflights and walking on the moon.
The first four flights tested the equipment used in the Apollo Program. Six of the other seven flights landed on the moon. The first Apollo flight happened in 1968. The first moon landing took place in 1969. The last moon landing was in 1972.
A total of 12 astronauts walked on the moon. The astronauts conducted scientific research there. They studied the lunar surface. They collected moon rocks to bring back to Earth.

What Spacecraft Were Used for the Apollo Program?
NASA designed the Apollo Command Module for this program. It was a capsule with room for three astronauts. The astronauts rode in the Command Module on the way to the moon and back. It was larger than the spacecraft used in the Mercury and Gemini programs. The astronauts had room to move around inside the spacecraft. The crew area had about as much room as a car.
Another spacecraft, the Lunar Module, was used for landing on the moon. This spacecraft carried astronauts from orbit around the moon to the moon's surface, then back into orbit. It could carry two astronauts.
Two types of rockets were used for the Apollo program. The first flights used the smaller Saturn I (1) B rocket. It was about as tall as a 22-story building. This rocket had two stages. That means it was made of two parts. When the first part ran out of fuel, it dropped away from the other and burned up in Earth's atmosphere. The second part continued flying. The Saturn IB rocket was used to test the new Apollo capsule in Earth orbit.
The other flights used the more powerful Saturn V (5) rocket. This three-stage rocket sent the Apollo spacecraft to the moon. It was about as tall as a 36-story building.

When Did Humans First Visit the Moon?
The first manned mission to the moon was Apollo 8. It circled around the moon on Christmas Eve in 1968. However, Apollo 8 did not land on the moon. It orbited the moon, then came back to Earth. The crew was Frank Borman, Bill Anders and Jim Lovell.
The first moon landing occurred on July 20, 1969, on the Apollo 11 mission. The crew of Apollo 11 was Neil Armstrong, Michael Collins and Buzz Aldrin. Armstong and Aldrin walked on the lunar surface while Collins remained in orbit around the moon. When Neil Armstrong became the first person to walk on the moon, he said, "That's one small step for (a) man; one giant leap for mankind."

Apollo 13 is one of the more famous lunar missions. A movie was made about this flight. Apollo 13 was supposed to land on the moon. On the way there, the spacecraft had a problem. NASA had to figure out how to bring the astronauts home safely. Apollo 13 flew all the way around the moon before returning home. Despite the problem, they were able to land safely on Earth.

How Did Astronauts Land on the Moon?
The Apollo spacecraft were launched on top of the Saturn V rocket. The Saturn V was made of three stages. The first two stages used up their fuel reaching orbit. The third stage was used to push the Apollo Command Module and Lunar Module to the moon. Once the spacecraft reached the moon, the two modules separated from each other. Two astronauts in the Lunar Module landed on the lunar surface. The third astronaut stayed in the Command Module in orbit around the moon.
On the last three missions, astronauts drove on the moon with the lunar rover. Astronauts drove the lunar rover to explore more of the moon's surface. The lunar rovers were made so they could be folded to fit in a storage area on the Lunar Module. The lunar rovers were left on the moon.
When the two astronauts were finished working on the surface, they got back in the Lunar Module and launched. It went back into orbit around the moon and connected with the Command Module. The two astronauts got back into the Command Module. They left the Lunar Module behind and flew back to Earth. The Lunar Module crashed into the moon. The Command Module landed in the ocean, and a ship picked up the astronauts.

Why Was the Apollo Program Important?
In 1961, President John F. Kennedy challenged the nation to land astronauts on the moon by the end of the decade. NASA met that challenge with the Apollo program. It was the first time human beings left Earth orbit and visited another world. These missions made it possible to explore more distant worlds further in the future.

What Was the Saturn V?

The Saturn V was a rocket NASA built to send people to the moon. (The V in the name is the Roman numeral five.) The Saturn V was a type of rocket called a Heavy Lift Vehicle. That means it was very powerful. It was the most powerful rocket that had ever flown successfully. The Saturn V was used in the Apollo program in the 1960s and 1970s. It also was used to launch the Skylab space station.

How Big Was the Saturn V?
The Saturn V rocket was 111 meters (363 feet) tall, about the height of a 36-story-tall building, and 18 meters (60 feet) taller than the Statue of Liberty. Fully fueled for liftoff, the Saturn V weighed 2.8 million kilograms (6.2 million pounds), the weight of about 400 elephants. The rocket generated 34.5 million newtons (7.6 million pounds) of thrust at launch, creating more power than 85 Hoover Dams. A car that gets 48 kilometers (30 miles) to the gallon could drive around the world around 800 times with the amount of fuel the Saturn V used for a lunar landing mission. It could launch about 118,000 kilograms (130 tons) into Earth orbit. That's about as much weight as 10 school buses. The Saturn V could launch about 43,500 kilograms (50 tons) to the moon. That's about the same as four school buses.

What Is the History of the Saturn V?
The Saturn V was developed at NASA's Marshall Space Flight Center in Huntsville, Ala. It was one of three types of Saturn rockets NASA built. Two smaller rockets, the Saturn I (1) and IB (1b), were used to launch humans into Earth orbit. The Saturn V sent them beyond Earth orbit to the moon. The first Saturn V was launched in 1967. It was called Apollo 4. Apollo 6 followed in 1968. Both of these rockets were launched without crews. These launches tested the Saturn V rocket.
The first Saturn V launched with a crew was Apollo 8. On this mission, astronauts orbited the moon but did not land. On Apollo 9, the crew tested the Apollo moon lander by flying it in Earth orbit without landing. On Apollo 10, the Saturn V launched the lunar lander to the moon. The crew tested the lander in space but did not land it on the moon. In 1969, Apollo 11 was the first mission to land astronauts on the moon. Saturn V rockets also made it possible for astronauts to land on the moon on Apollo 12, 14, 15, 16 and 17. On Apollo 13, the Saturn V lifted the crew into space, but a problem prevented them from being able to land on the moon. That problem was not with the Saturn V, but with the Apollo spacecraft. The last Saturn V was launched in 1973, without a crew. It was used to launch the Skylab space station into Earth orbit.

How Did the Saturn V Work?
The Saturn V that launched the Skylab space station only had two stages. The Saturn V rockets used for the Apollo missions had three stages. Each stage would burn its engines until it was out of fuel and would then separate from the rocket. The engines on the next stage would fire, and the rocket would continue into space. The first stage had the most powerful engines, since it had the challenging task of lifting the fully fueled rocket off the ground. The first stage lifted the rocket to an altitude of about 68 kilometers (42 miles). The second stage carried it from there almost into orbit. The third stage placed the Apollo spacecraft into Earth orbit and pushed it toward the moon. The first two stages fell into the ocean after separation. The third stage either stayed in space or hit the moon.

The public can view one Saturn V rocket at NASA's Johnson Space Center in Houston, and another at the agency's Kennedy Space Center near Orlando, Florida. And, while these are each complete rockets, they include an assortment of stages for the various missions. Neither one includes the full set for either of the missions, Creel explained.
A third Saturn V rocket, a dynamic test vehicle from the Apollo program, is currently on display in the Saturn V Hall at the Davidson Center for Space Exploration at the U.S. Space & Rocket Center, the official visitor center for NASA's Marshall Space Flight Center in Huntsville, Alabama. Additionally, visitors at the center can see a replica of the rocket standing outside at the facility.
