On July 16, 1969, Apollo 11 was launched from Kennedy Space Center in Florida. After a successful landing on the moon’s surface, Neil Armstrong became the first human to step foot on our celestial neighbor, on July 20, corresponding to the Hebrew date of 6 Menachem Av (after nightfall in eastern U.S.).

During the “Nine Days" from Av 1st to the Ninth of Av, we mourn the destruction of the Holy Temple. We abstain from meat and wine, music, haircutting, bathing for pleasure, and other joyous (and dangerous) activities. (The particular mourning customs vary from community to community, so consult a competent halachic authority for details.)
Consumption of meat and wine is permitted on Shabbat, or at a seudat mitzvah (obligatory festive meal celebrating the fulfillment of certain mitzvot) such as a brit (circumcision), or a siyum celebrating the completion of a course of Torah study (i.e., a complete Talmudic tractate). The Lubavitcher Rebbe, of righteous memory initiated the custom of conducting or participating in a siyum on each of the Nine Days (even if one does not avail oneself of the dispensation to eat meat).
Citing the verse "Zion shall be redeemed with mishpat [Torah] and its returnees with tzedakah," (Isaiah 1:27) the Rebbe urged that we increase in Torah study (particularly the study of the laws of the Holy Temple) and charity during this period.

There is an outer world and there is an inner world. As deep as you penetrate, as high as you reach, there is always something breathing inside.
The outer world is made of things. Breathing inside the things are words.
Words are the outside. Inside the words are stories.
The story is the outside. Inside the story is a thought.
Thoughts are the outside. Inside the thoughts is a great light.
At the origin of all light is the beginning that cannot be known.
The outside we can touch and come to know.
The inside—we must wait and be still, so that it may speak to us.
As it did at Sinai. As it does whenever we learn Torah with all our heart and soul.
