Even without a total eclipse, tonight's lunar eclipse was a beautiful sight. #stlwx did not let us down, not a cloud in sight! #lunareclipse 📷 Sony A6700 w/ Celestron Nexstar 90GT
This Is Going To Hurt is, read with a clinical eye, a textbook case study of moral injury and post-traumatic stress in a competent doctor, narrated by the patient himself, with the diagnosis hidden in plain sight.
This will likely serve as a wake-up call to those not paying attention to the US-China space race—which, to be clear, is the vast majority of Americans.
There are many many unsolved problems in the world, many great ideas hiding in plain sight that were actually solvable that could have been multi-billion or multi-t trillion dollar businesses a while ago, but nobody's building them and not for any reason other than nobody went and did it.
At even $500/kg, launch cost is only 5% of the total satellite deployment cost, so a lunar mass driver is unlikely to drastically improve the economics of space-based AI, by reducing launch costs.
Even for $5.2b per launch, Orion is so overweight that there does not exist a booster nor an upper stage that can launch it to Low Lunar Orbit and return it to Earth.
A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com.
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
statements, and a person can change their mind, which is recorded too.
About the English under a post
Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
