Half a century ago, on 20 July 1969, Neil Armstrong was in the final stages of the lunar descent, just a few thousand feet above the surface, when suddenly his on-board computer indicated a critical alarm. For three nail-biting seconds it looked as if the mission would have to be aborted. However, Armstrong was given a “go” to continue, and after several more alarms the Eagle touched down safely on the Moon.
Very insightful talk by Robert Wills, engineer at Cisco. No only does it give an insight in how to land a Lunar Lander on the moon, it also provides a thorough analysis of the hardware and software design principles that saved the mission.
In honour of the upcoming 50th anniversary of the first lunar landing – which launched on July 16th, 1969 – Destin from SmarterEveryDay went to the NASA facility where they keep about 70% of the Moon Rocks that were ever collected (Apollo Missions 11, 12, 14, 15, 16, and 17). The video offers us a truly amazing inside view on how the rocks are stored, manipulated, documented, etc.
Extra kudos to his guide Andrea Mosie, who speaks in such a passionate, open, and honest way about it all. It must be a joy and privilege to work with her.
Wylie Overstreet and Alex Gorosh took a telescope around the streets of LA and invited people to look at the Moon through it. Watching people’s reactions to seeing such a closeup view of the Moon with their own eyes, perhaps for the first time, is really amazing.
A real-time journey through the Apollo 17 mission. Relive every moment as it occurred in 1972.
This is magnificent! It’s a timeshifted playback – with audio, photos, transcripts, etc. – of the events of Apollo 17, the last mission of the Apollo program which took us to the moon, exactly as they happened 43 years ago.
This visualization shows the Moon’s phase and libration at hourly intervals throughout 2015, as viewed from the northern hemisphere. Each frame represents one hour. In addition, this visualization shows the Moon’s orbit position, sub-Earth and subsolar points, distance from the Earth at true scale, and labels of craters near the terminator.
