Check it out:

At this time in 1969, much of the world was caught up in the drama of Neil Armstrong making the first human footprints on the moon.

And just as NASA threw its best technology at getting to the moon in 1969, the agency and some of its biggest fans are throwing today’s best technology at celebrating the 45-year anniversary this week.

Apollo 11 touched down on the moon’s surface for the first time July 20, 1969.

In tribute, the space agency has generated a lively global conversation with a series of tweets carrying the hashtag #Apollo45. The posts retrace the steps of the moon mission, from launch to return.
