Fifty years later, remnants of the 1969 Apollo 11 moon landing can still be seen on the lunar surface, which are essentially frozen in time.
Without the danger of wind and water erosion that we know on Earth, even the footprints left by the Apollo 11 astronauts are considered cemented in the Moon's surface.
Buzz Aldrin described the moon's "great devastation" when he and Neil Armstrong entered the lunar landscape, which remained untouched for 4.5 billion years.
The astronauts left numerous evidence for their expedition, some scientific and some sentimental.
They installed a camera, a lunar module (LM), a Laser Ranging RetroReflector (LRRR), and a Passive Seismic Experiment Pack (PSEP) to send information back to Earth in the future, and deposited some of the equipment needed to collect the reloaded Samples were used on the Eagle spaceship ̵
They also featured some commemorative items, including a family photograph, mission patches, fallen astronaut medals, a silicon disc with world leaders' messages, and an American flag placed in frozen terrain.
Five decades later, many of these objects are still visible on satellite imagery taken by NASA's Lunar Reconnaissance Orbiter, while no one has yet returned to the Apollo 11 site.
Fifty years later, remnants of the first Apollo 11 moon landing from satellite images of NASA's Lunar Reconnaissance Orbiter can still be seen on the lunar surface. This 2011 image is one of the clearest ever captured by Apollo 11.
The Apollo 11 astronauts have left plenty of evidence for their expedition, including a camera, a lunar module (LM), a Laser Ranging RetroReflector (LRRR) and Passive Seismic Experiment Package (PSEP) to send information back to Earth in the future. Some of these instruments as well as the astronaut's track to the Small West Crater in the Sea of Tranquility are still visible. The above 2011 satellite image shows the Apollo 11 site along with a photo taken during the expedition.
Neil Armstrong and Buzz Aldrin, the first people to enter the moon on July 20, 1969, are seen rearing up American flag on the lunar landscape. The flag fell as soon as the astronauts left, but it is believed that they are still sitting on the grounds.
The clearest images of the Apollo 11 site were taken in 2011 showing the LRRR and its cover, the PSEP, the LM and the camera. The traces that the instruments have made through the dust are also visible.
The American flag is no longer standing and fell to the ground the moment Apollo 11 took off.
Dennis LaCarrubba, who worked for the company that had bought the flag off the rack before the mission, said the nylon has since been bleached by the sun, since the moon has no atmosphere to keep it from UV rays protect.
Have you ever seen a burned newspaper from a fireplace? All colors are gone and everything, "LaCarrubba told The Atlantic. "That's how the flag would look like now."
While the first flag is not visible in satellite imagery, other flags placed at later Apollo airfields appear to have been bleached as well.
For years, scientists thought solar radiation would completely destroy the flags, but the photographs taken over the past decade show that the emblems were in place.
LROC's cameras do not capture enough detail to detect the bootprints of astronauts, many of which were likely erased by the startup blasts.
Without the danger of wind and water erosion that we know on Earth, even the footprints of the Apollo 11 astronauts are still cemented in the lunar surface. Buzz Aldrin is pictured during the expedition.
While the American flag set up at Apollo 11 is not visible in satellite imagery, other flags will later be seen at Apollo airfields. They seem to have been bleached by the sun in all colors, because the moon has no atmosphere to protect against UV rays.
No one has ever returned to the Apollo 11 landing site, where Aldrin can be seen alongside the Solar Wind Composition experiment. The SWC was part of the Early Apollo Scientific Experiment Package (EASAP) at the tranquility base on the lunar surface.
The images prove that despite numerous conspiracy theories, the moon landing was not a joke orchestrated by the US government in a competitive space race.
Julie Stopar, a member of the LROC imaging team, said she always had photos of Apollo locations if she came across conspiracy theorists.
"You'll jokingly – and in some cases not so jokingly – ask me," Are you sure we've landed on the moon?
Stopar said she tells doubters, "Yes, I'm sure, I saw it and we have pictures of it."
"And then I show them the pictures and then they say," Oh, okay, me think, that's pretty convincing. "
Last week, the US and other countries celebrated their 50th anniversary of the Moon Landing, an event that sets the age for more than half a billion people around the world was and is one of the greatest achievements of humanity.
On July 20, 1969, Armstrong and Aldrin broke away from the spacecraft Columbia, which was controlled by Michael Collins in Lunar Orbit, and descended to the Sea of Tranquility in the lunar lander, Eagle.
The Eagle landed with only 17 seconds to save fuel. Six hours later, Armstrong first entered the lunar surface and for ages proclaimed, "This is a small step for man, a giant leap for humanity."

Almost five decades have passed since the last moon landing in 1972. Many nations and nonprofits organizations are working on their own moon landing, while commercial companies hope to make the moon a tourist destination one day.
NASA has already established guidelines for commercial spacecraft, including restrictions on Apollo locations.
For All Moonkind, an organization of lawyers specializing in space law, has drafted a bill with members of the Congress identifying protected "heritage sites" on the Moon and approved by the Senate for Trade, Science and Transport Committee beginning this month.
WHAT WAS THE APOLLO PROGRAM?
The NASA photo, taken on July 16, 1969, shows the huge, 363-foot Apollo 11 spacecraft 107 / Lunar Module S / Saturn 506) spacecraft launched from Pad A, Launch Complex 39. Kennedy Space Center (KSC), at 9:32 pm (EDT).
Apollo was the NASA program that was launched in 1961 and brought NASA to the moon.
The first four flights tested the equipment for the Apollo program and six of the other seven flights managed to land on the moon.
The first manned mission to the moon was Apol lo 8, which circled around them on Christmas Eve 1968 but did not land.
The crew of Apollo 9 circled Earth for ten days and completed the first manned lunar module flight – the portion of the Apollo rocket that Neil Armstrong would later land on the Moon.
The Apollo 11 mission landed on July 20, 1969 as the first on the Moon.
The capsule landed on the Sea of Calm with Mission Commander Neil Armstrong and pilot Buzz Aldrin.
Armstrong and Aldrin walked on the lunar surface while Michael Collins remained in orbit around the moon.
When Armstrong was the first person to walk on the moon, he said: "This is a small step for (one) man; A giant step for humanity. "
Apollo 12 landed on the ocean of storms later this year on November 19, NASA writes.
Apollo 13 was the third mission to land on the Moon. Nearly 56 flying hours later, an oxygen tank explosion forced the crew to break off the moon landing and enter the Aquarian lunar module to return to Earth.
Apollo 15 was the ninth manned lunar mission in the Apollo space program and at that time was considered the most successful manned space flight to date, as scientific exploration took longer and had more weight than previous missions.
The last Apollo moon landing took place in 1972, after a total of 12 astronauts had landed on the lunar surface.
