45th Anniversary of First Men on the Moon: Spot Apollo Landing Sites

On July 20, 1969, the Apollo 11 mission delivered astronauts Neil Armstrong, Buzz Aldrin, and Michael Collins to the moon. This Sunday marks the 45th anniversary of the first time people landed on our lunar neighbor. (See “First Explorers On The Moon.”)

With the aid of binoculars, you will be able to see some of the Apollo landing sites. However, since the moon will be in its waning crescent phase, you won’t be able to see the exact Apollo 11 landing site. But two other Apollo sites—12 and 14—will be visible. 

The moon is gravitationally locked to Earth, meaning we always see the same side of the lunar orb. Therefore, familiarizing yourself with the major landmarks across its face is fairly easy. The scattered dark patches—called maria or seas—dotting the moon’s face were once thought to be actual oceans filled with water and life. They are in fact gigantic crater basins formed over three billion years ago, when mountain-size rocks smashed into the ancient moon, causing liquefied rock to bubble up and ooze out to harden into the smooth, dark areas we see today.

It is on the edge of one of these maria, called the Sea of Tranquility, where humans first landed on the moon. Apollo 11 and the five other landing sites are all easily found scattered across the lunar face.

Don’t expect to see equipment left by the Apollo astronauts or their footprints, though. For that you would need NASA’s Lunar Reconnaissance Orbiter, which flies just above the surface of the moon.

We will have to wait until August 10 for the next full moon phase in order to see all six Apollo landing sites, including the iconic Apollo 11 site. But if you’re looking for some moon maps to get the full lunar experience, then check out Google’s zoomable version or the Lunar Society’s interactive photo atlas.

If clouds block your view of the moon this Sunday, or if you want to tour the moon through a telescope—at least virtually—then the astronomy outreach venture Slooh will provide a good way to mark this anniversary. It will broadcast a special program via live feed from Dubai in the United Arab Emirates.

The fun starts Sunday, July 20, at 5:30 p.m. PDT/8:30 p.m. EDT/00:30 UTC (7/21). For international times, go to http://goo.gl/pUHQih.

Enjoy your lunar holiday!

    I was in the US Air Force when this happened in 1969 stationed At Maxwell Field, Alabama. I was a team leader on the Air Force side of the Cape when SkyLab went into outer Space.

    1969 in July,
    The 20th to be exact.
    I was looking up in the sky
    To see if news I’d heard was fact.
    A gin and tonic in my hand,
    I had drunk several, I think.
    My eyes were a bit blurry, and
    I stumbled and I spilled my drink.
    But ’twas a time in history,
    A matter over my fogged mind.
    Maybe a drunken step for me,
    But “one giant leap for mankind.”

    I looked and looked and looked, and soon
    Yes, I saw the man in the moon.

    “Don’t expect to see equipment left by the Apollo astronauts or their footprints, though.”

    AHHAAH I KNEW IT

    I have been confused with conspiracy theories on the landing of apollo 11 on moon .and now also I haven’t fully accept landing on moon if yuo have an evidence which can convince me and athers with this point . Thanks

    I think it’s amazing that we have the ability to reach out into space and actually have another human walk upon another planet (moon). But at the same time I can’t help but wonder why we haven’t gone back to establish a scientific base of exploration. Sooner or later we are going to visit other planets in the solar system and we need to work out some of the bugs before we try it somewhere that would be to far away to help if there were a crisis. We should be working harder to get this done. Back in the day we had a president that basically dared ourselves to get it done and we did. Where is that get up and go attitude today. Today we can’t even send up our own people to the space station without sending them to Russia for a ride. Talk about embarrassing! We used to be t he country that was known for getting the difficult done, And now we are reduced to hitching a ride from another nation.
    Come on America!!! We can and MUST get that “CAN DO” attitude back before we are left in t he dust.

    By the way, GREAT ARTICLE!!!

    Landing on the moon was a great accomplishment for mankind. It is encouraging to know that as a nation we can accomplish such unfathomable things – at least by 1960 standards. Now, with all of the technology at our disposable – it can be frustrating when something isn’t possible and it can be visualized.

    Smart Energy Today and the reflective insulation industry is a major beneficiary of the technologies that came out of the trip to the moon. Extreme temperatures in space necessitated a way to protect the astronauts and the space equipment. Radiant barrier technology, a chief component in reflective insulation, is a product that is being used in homes to make them more energy efficient. This technology is used in everyday scenarios.

    A simplistic analogy of how radiant barrier technology works is to think of the baked potato. It’s wrapped in foil to keep it warmer longer by keeping the heat in. Or in reverse a sun shield for cars that keeps the heat out.
