July 20th is a special date reserved annually to celebrate Space Exploration Day. This day honors the monumental achievement in 1969 when the first men, Neil Armstrong, and Buzz Aldrin stepped onto the moon’s surface under NASA’s Apollo 11 mission. The day serves to highlight the remarkable progress we’ve made in exploring the vast cosmos, to promote the importance of continuing such exploration, and to inspire up-and-coming generations to delve into space sciences.
On this day, we honor the past, celebrate the present, and look forward to the thrilling future of untapped cosmic exploration.
History of Space Exploration Day
Each year, on July 20th, the remarkable achievement of human space travel is celebrated in the form of Space Exploration Day. The historic lunar landing achieved by NASA’s Apollo 11 mission is commemorated by this important day. On July 20, 1969, astronauts Neil Armstrong and Buzz Aldrin became the first humans to set foot on the moon, securing their place in the annals of human history.
American writer and avid space enthusiast, J. David Baxter, came up with the idea for Space Exploration Day in 1971, two years after the monumental moon landing. This concept was met with widespread enthusiasm and approval from the scientific community, space exploration followers, and the public at large.
National recognition for Space Exploration Day in the United States was received in 1984 when then-President Ronald Reagan officially declared July 20th as a day to celebrate our strides in space exploration. In this proclamation, Reagan emphasized the importance of acknowledging scientific and technological strides and fostering an environment where future generations could freely pursue their curiosity.
Today, this day is celebrated globally with several activities designed to inform and inspire. Space Exploration Day is a reminder of our never-ending quest for knowledge, our achievements in space discovery, and our continued push towards new frontiers. It serves as an opportunity to look back on our achievements in space exploration and motivate future generations to consider careers in space exploration and related scientific fields.

8 Interesting Facts About Space Exploration
Space Travel Alteration
Astronauts can grow approximately two inches taller after spending a prolonged period in space due to the absence of gravity which causes the vertebrae to expand.
Footprint on Moon
A footprint left by an astronaut on the moon could last for millions of years, because there is no wind or water to disturb it.
First Animals in Space
Before humans went into space, several animals like fruit flies, mice, monkeys, and dogs were sent up to space to study the survival of beings in space.
Mars Rovers
Mars Rover vehicles are operated by a team on Earth using a combination of autonomous systems and direct control. They move only a couple of hundred feet per day.
Proxima Centauri
The nearest star to our solar system, Proxima Centauri, is so far away that if we were able to travel at the speed of light, it would still take us over 4 years to reach it.
The Dark Side of the Moon
The 'dark side of the moon' is a myth. Both sides of the moon see the same amount of sunlight but only one face is ever seen from Earth because the moon's rotation period is the same as its orbital period.
Space Speed
The average speed of the space shuttle is 17,500 miles per hour. At this speed, you could travel to Los Angeles from New York in about 10 minutes.
Abundance of Stars
