Title: "Three Engineers Walk Into a Bar" - Land on the Moon 8 Years Later
Post by: Unbeliever on March 01, 2019, 06:32:32 PM
Landing on the lunar surface doesn't take a vast government program any more, apparently. This may well be the future of space missions, so maybe a lunar colony won't be far off.

https://en.wikipedia.org/wiki/SpaceIL

QuoteSpaceIL is an Israeli organization, established in 2011, that was competing in the Google Lunar X Prize (GLXP) to land a spacecraft on the Moon. SpaceIL successfully launched its Beresheet lander on 22 February 2019, which is expected to land on the Moon's surface on 12 April 2019. The Beresheet mission includes plans to measure the Moon's local magnetic field to help understand how it formed, and also carries a digital "time capsule". Beresheet would be the first Israeli spacecraft to travel beyond Earth orbit and the first private lander on the Moon. Israel would also become the fourth country, after the Soviet Union, United States, and China, to land a spacecraft on the Moon.
The SpaceIL team was founded as a nonprofit organization wishing to promote scientific and technological education in Israel. Its total budget for the mission is estimated at US$95 million, provided by Israeli billionaire Morris Kahn and other philanthropists, as well as the Israel Space Agency (ISA).

I very much hope so.  If commercial enterprises can't do it eventually, we can't afford it.

Correct, but that is why we need government, to do the things that have to be done, that we can't afford.

The more the better.  Ultimately, we aren't going to escape the planet one nation or company at a time.  It is going to be co-operative in general ways or it won't succeed. 

I truly do think that sci-fi writers have shown us the way.  It is not going to be easy, and people will die on the the way to Mars and beyond.  But people died in ships seeking understand the surface of the Earth and that didn't stop them from trying.

We are seekers.  We first wondered what was "over that hill", then "over that mountain" and even "what's on the top of that mountain"?

The drive that pulls us to see what is on the top of the mountain, cross a desert, try to see the bottom of the ocean...  Those things now drive us to want to step on Mars.  Every time we say "been there, done that", we look for something new to try. 

If we ever find a new intelligent species "out there somewhere" , I suspect it will be too hard to make war.  That may be the only saving grace of distance.  And, this may seem silly, but if we talk, the first word we will understand is the name of the planet we meet

It will mean "dirt".  Well, "soil or ground", maybe.  Every civilization will call their planet some version of "dirt".  Ya gotta start somewhere...

If a ship hits the moon, does it make a sound?  Probably not.  Depends on how you define "sound".  But it would make it vibrate for about 25 minutes.  Just saw that today on the Science Channel.

Going to Moon.  Probably for the same reason that the Space Shuttle got replaced by a drone.  Constellation project was cancelled.

A friend of mine has worked on the Orion capsule project.

https://en.wikipedia.org/wiki/Orion_(spacecraft)

Artemis replaced Constellation.  First manned flight, 2023.  First unmanned flight 2021.  The unmanned flights are drones probably, like the drone Space Shuttle.

  • the race was "won", we showed those damn Rooskies who's "better"; and
  • Nixon wanted to kill off what was seen as a Kennedy accomplishment, made all the worse for happening on his watch.  He could have made it his by upping the ante and setting the task of a permanent lunar base by the end of the 70s, but that's not the way his dark and twisted brain worked.  And,
  • even though the Apollo program had a 14:1 return on investment, the average American didn't see it immediately, so public support faded; and
  • the Soviet space program more or less ceded the moon (mainly due to the death of Sergei Korolev, and the constant failures of the N1 (https://en.wikipedia.org/wiki/N1_(rocket)#Launch_history), of which it would be charitable to call them merely disastrous) and focused on space stations, providing no more "competition".

Partly.  The early successes of the Soviet space program were partly because of the top-down nature of their system that could simply order things done, partly because the American space program was hampered by competition between the different military branches, each of which had their own programs fighting for resources, partly because Sergei Korolev was a hand's-down undeniable genius, andâ€"it is allegedâ€"partly because Eisenhower held the space program back until after the Soviets orbited a satellite first so that the international precedent of unfettered overflight was set by them.

The later failures of the Soviet space program are partly attributable to the top-down nature of their system that could simply order things done without regard to whether the orders were reasonable, partly to the unexpected death of Korolev, and partly due to American efforts being concentrated in NASA rather than divided between the military branches.

Probably the biggest setback all around was the loss of Korolev; it's likely he could have either sorted out the problems with the N1, or scrapped the project in favor of one that worked.  I think it's likely we'd have a permanent moonbase by now if Korolev had lived, since the race for the moon would have continued.  The next race after landing would have been for a permanent presence; Korolev would have pushed for it and he had sufficient stature that he could have gotten itâ€"and there's no way the US government would have allowed an unanswered Soviet base on the moon.

The first lie, is how much is reported (control of boundary of narrative).  Anything outside of the official boundary ... is debunked.

The second lie, is to carefully take the facts (as limited above) and spin them into an interpretation (why did Oswald shoot JFK).  With assassinated assassins, this leaves a big hole.  With the guy who shot MLK, he lives awhile longer, but people were careful to debunk anything he said (he was an assassin, so why believe him?).
