There were 2 other commercial landing that blacked out just before landing must be something they all didn’t take care of or maybe nasa is holding out some secret info

> just before landing

I would characterize it as failing during the landing process, or lithobraking if you will.

Obligatory Sagan quote: > Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, ev…

This is why I do not understand people who would jump at the chance to live on a permanent Martian or Lunar colony.

I would direct you to another Sagan quote as part of Wanderers - a short film by Erik Wernquist : https://vimeo.com/108650530

For all its material advantages, the sedentary life has left us edgy, unfulfilled. Even after 400 generations in villages and cities, we haven’t forgotten. The open road still softly calls, like a nearly forgotten song of childhood. We invest far-off places with a certain romance. This appeal, I suspect, has been meticulously crafted by natural selection as an essential element in our survival. Long summers, mild winters, rich harvests, plentiful game—none of them lasts forever. It is beyond our powers to predict the future. Catastrophic events have a way of sneaking up on us, of catching us unaware. Your own life, or your band’s, or even your species’ might be owed to a restless few—drawn, by a craving they can hardly articulate or understand, to undiscovered lands and new worlds.

Herman Melville, in Moby Dick, spoke for wanderers in all epochs and meridians: “I am tormented with an everlasting itch for things remote. I love to sail forbidden seas…”

Maybe it’s a little early. Maybe the time is not quite yet. But those other worlds— promising untold opportunities—beckon.

Silently, they orbit the Sun, waiting.

Beautiful images of Earth from the lander: https://twitter.com/ispace_inc/status/1650506233575604227/ph... and https://twitter.com/ispace_inc/status/1649707714447306753/ph...

How large are these craters on the moon? https://twitter.com/ispace_inc/status/1650506233575604227/ph...

Quick math:

When viewed from the moon, the earth's diameter subtends an angle of about 0.033 radians. On the other hand, if the photo was taken from an orbital altitude of 100km, then the lunar horizon is about 600km away from the viewpoint (using Pythagoras' theorem).

So at the horizon, a crater the same apparent size as the earth would be roughly 0.033 * 600 = 20 km across.

The untold want by life and land ne’er granted,

Now voyager sail thou forth to seek and find.

Once is chance, twice is coincidence, three times ...

...means landing must be one of the tricky parts. Just like how landing a plane is one of the tricky parts.

Bonus points if you attach some to plaques and give them away to various nations which then lose some of them.

Assuming it wasn't lost or stolen since 1970, I wonder what the Taliban is doing with its moon rock.

Maybe they should be focusing on building something robust enough to land or even crash on the moon's surface and keep transmitting for a while, then work on the cool rover payload after that. It's perplexing to me not that it failed, but that they don't (so far) have any idea why or how.
