then communications were cut off, and no more information was sent back. Have any of these moon landings been done at night where people have been able to watch it happening through a telescope? Or are things so small at the moon's distance that there'd be nothing to see?

Just watched the ted talk from the woman who came up with the algorithm to photograph the black hole and she had a slide of the best picture we can get of the moon from earth and she said each pixel on that picture could fit something like 600,000 oranges. don't think it's possible that we can see a spacecraft landing on the moon with what we have.

Is the issue Earth's atmosphere (and other stuff) messing up the optical image at that range/detail/resolution?

If a huge-camera-satellite (eg, spy-sat class) were placed at a Lagrange point, would it increase our ability to see at extremely high resolution?

Sorry for the noob questions.

It seems that they just got a new word in the dictionary: https://mobile.twitter.com/teamspaceil/status/11163129311033... I find it a bit irritating to be that cocky when it comes to space technology. Better luck next time!

Here I was thinking the new dictionary entry was going to be something like: Beresheet: (v) To fail dramatically after overwhelming confidence

So hubris?

It's hard to conjure much sympathy for a nationalistic boondoggle with little scientific value that's trying to participate in a space race that ended decades ago. Now, instead of a flag, they have a commemorative crater in the desert. Talk about symbolism...

This project wasn't started by the state or by any university. This was a, mostly, volunteer project that wanted to excite children about STEM and space and to educate the young generation. The Prime Minister was invited because it was cool, but it was a private endeavour.

Not sure I would call Netanyahu "cool".

Hubris leads to Beresheet.

It's time to retire the tired old nation-state space-race narrative. We're all in this together people. Their failure is our failure.

Nothing could be further from the truth. These folks are fierce with nationalistic and sectarian pride in their vehicle. https://mobile.twitter.com/teamspaceil/status/11163129311033...

Honestly, I consider this consent to mock them for their failure.

This cockiness is on the same level as calling the Titanic "The Unsinkable". They wanted to fail modestly, they should have behaved modestly.

There was mention there about IMU issues - losing track of where you're pointing, then trying to recover could mean you're pointing the wrong way (while still running the main engine ....)

The prime minister of Isreal announced they'll try again in two years. So that judgment may be a little premature. Regardless knowledge transfer isn't limited to either of those.

Is this a government venture or private? I read that it is private but then I see quotes about the PM like this.

Private but partially funded by the government; the PM was at the launch and had (before the crash) been trumpeting it as a success for the country as a whole

Sorry, I still stand with Palestine. Since this had no scientific value, they and their hideous apartheid state can suck it.

Count your blessings. They are the 4th country to reach the Moon (albeit at 1km/s).

US, USSR, and China have successfully landed on the moon. Japan, ESA, India, and SpaceIL all have crashed on the moon (counting as reached). https://en.wikipedia.org/wiki/List_of_spacecraft_on_the_Moon

That being said, ESA landed on a comet. Which is arguably a much harder shot to make ;) literally, you shoot, wait a decade, and cross your fingers during landing ^^
