The world will commemorate the 50th anniversary of the Apollo 11 moon landing this year. NASA is inviting everyone to celebrate man's historic accomplishment of conquering space.

Flashback To Summer Of 1969

On July 20, 1969, about 530 million people worldwide watched the televised Apollo 11 Moon landing as it happened. The world watched in awe as American astronaut Neil Armstrong made a history of being the first man ever to step on the lunar surface. Mankind heard Armstrong's voice describing the event as he took "one small step for a man, one giant leap for mankind."

The summer of 69, as it is also popularly known, is considered a milestone in man's spaceflight history.

Commemorative Audio History

As part of its preparation for the anniversary, the agency will launch a project called NASA Explorers: Apollo, a commemorative audio series related to the Apollo missions and Moon exploration on its social media accounts. Entries from the public will be added to NASA's archive of oral histories and interviews related to the Apollo moon landing.

The space agency is asking the public who still remember the historic event to record their memories of the moon landing and the Apollo era from 1960 to 1972. Interested participants can record a brief recollection using a smartphone and e-mail the sound recording to apollostories@mail.nasa.gov.

Participants can record themselves or interview another person. NASA may send a follow-up e-mail to participants. Shorter recordings are preferred and the longer clips might be considered for NASA's social media.

Here are some of the questions that the public can answer for the audio recording:

• What do you think it would be like to see humans walk on the Moon again?
•  Where were you when humans walked on the Moon for the first time?
•  Describe who you were with, what you were thinking, the atmosphere and how you were feeling.

Those interested can submit entries until the end of 2019. However, those who can submit before June 14 will have the best chance of being included in the audio series memoirs. The complete details and recording instructions are posted on NASA's event site.
