July 20 - Moon Day

   Posted on July 20, 2022     


This is an update of my post published on July 20, 2011:



Celebrate the first day that human beings stepped foot on another world!

When you feel discouraged about people's stupidity and cruelty, look up in the sky at the moon and remember that, MORE THAN HALF A CENTURY AGO, we went there! Today marks the 53rd anniversary of Apollo 11's successful voyage of hundreds of thousands of miles to our nearest celestial neighbor, in 1969.





We can also celebrate the 1976 landing of the Viking I Lander on Mars. This intrepid unmanned spacecraft traveled hundreds of millions of miles to Earth's next-door planet, and it was the first to successfully land on Mars. Viking I transmitted many photos of Mars and ran a variety of experiments over a period of over six and a half years!



We need to get back to in-person explorations of the moon! And putting humans on Mars, too!

July 20 - Moon Day

 Posted on July 20, 2021

This is an update of my post published on July 20, 2010:



On this day in 1969, Buzz Aldrin and Neil Armstrong became the first humans to land on the moon. During the 21 hours that the two astronauts were on the moon, they planted a U.S. flag on the lunar surface, spoke to President Richard Nixon through a telephone-radio connection, took the first moon walks, and collected more than 47 pounds of lunar rocks.


And they did it all on TV! I was among the more than 600 million people watching―and for me it was THE highlight of TV in my childhood! (You Tube has lots of videos that include the first broadcast from another world.) 



Armstrong, Aldrin and astronaut Michael Collins flew to the moon on the space flight called Apollo 11. Once there, Collins stayed with the command ship, Columbia, while Aldrin steered the landing craft, Eagle, to the lunar surface, landing in the so-called Sea of Tranquility. (There is no liquid water on the moon, so it isn't really a sea.) NASA personnel in Houston, Texas, stayed in touch with the astronauts through radio transmissions and cheered them on.



Some of the big moments included Neil Armstrong announcing, “Houston, Tranquility Base here. The Eagle has landed,” and, when he first stepped down onto the dusty moon, “That's one small step for man, one giant leap for mankind.”









Check out this more detailed You Tube video about Apollo 11.




Did you know...?


One of the first things Buzz Aldrin did on the moon was to take communion privately and quietly. His church in Webster, Texas, still has the chalice used in the Lunar Communion.


The astronauts were supposed to sleep for five hours after landing on the moon, before they went outside. But like little kids too excited to sleep, they skipped the sleep period.

Even though we cannot see the astronauts' faces,
we can assume that they are pleased as punch to
be the first humans on the Moon!

Recordings of the original transmission of that first moonwalk were accidentally destroyed. Of course, there are lots of copies of the video in broadcast format, but NASA was happy when copies of the original footage were located in Australia, in one of the places that originally received the lunar broadcast.


Some people have concocted a crazy conspiracy theory that humans have never really flown to and walked on the moon. They claim that all of the moon landings (there were five more after Apollo 11) were hoaxes! 

One of the moon-landing deniers was bugging Buzz Aldrin for several minutes―in his face, over and over again accusing him of being a liar and a thief, and even calling him a coward―when Aldrin finally, famously, punched him in the face. The moon-landing denier sued Aldrin for the attack, but the lawsuit was quickly thrown out of court. (If you want to watch this widely-viewed incident, here it is.) 

Here is a website that briefly shows why we know the moon-landing deniers are wrong.


One way to prove that humans have been to the Moon
is to shoot a laser beam at it and clock its return. Buzz
Aldrin laid a reflector module on the Moon's surface so that
scientists on Earth could accurately measure the Moon's
distance over time. (The Moon is very very slowly getting
closer to the Earth.) Lots of different scientists have done
the simple experiment of sending a laser beam to the reflector.

This website was created in time for the 50-year anniversary of Apollo 11! The anniversary's logo features a photo of Mars and the words "the next giant leap."




Check out a personal account of a man who turned 13 on the day humans first walked on the moon.

July 20 - Moon Day 50!!!

Posted on July 20, 2019




Half a century since humans first landed on the Moon!

That's...astonishing to those of us who actually remember it. It still seems...so modern, so current, so cutting-edge of human exploration. I guess because, in the past 50 years, nobody's really topped it.

There have been - so far - zero humans landing on Mars, for example.

Neil Armstrong talked about a "giant leap" for humanity...but of course it was the 1960s (and, back then, the U.S. hadn't even had a single female astronaut!), and we hadn't done much in the way of getting rid of sexist language at that point...

...So Armstrong called it a giant leap for mankind

At any rate, while we celebrate the 50th anniversary of the first Moon landing, we should reignite our spirit of adventure and get excited about new explorations for humankind!




Look up local events to celebrate Apollo 50th! This article talks about some celebrations in my neck of the woods (not just Los Angeles, but all over "the West"). 

NASA has Apollo50th television programming and events listed here.

Turning to Mars, NASA has some great resources in its Mars Exploration Program.




Mars One is a private effort with the goal of starting a colony on Mars. Check it out!



Elon Musk has ambitious plans for SpaceX, including settling Mars and even terraforming it (changing the planet's atmosphere to make it livable for humans without domes or spacesuits.


Could we make Mars look like this someday?
If so, should we?
