Each of the several choices available in run 3 for selecting records at random from a database table comes with its own set of advantages and disadvantages. Depending on the specific requirements of the application, one of the methods can be more appropriate than the others.
Elon is probably mad it launched on an Ariane 5 and it went so perfectly, we’ll get an extra decade of science out of it.
The Ariane 5 really was a reliable rocket. It had some failures early on, like basically all rockets, but then it had 82 successful launches in a row and then one partial failure before having another long perfect streak.
Obviously, more expensive than modern reusable rockets but JWST was important enough of a payload, that I’m glad NASA/ESA chose Ariane. (Plus, given JWST’s delays, I imagine when that decision was made, SpaceX was still iterating and having occasional explosions.)
Efficiency is when the government abandons all its investments, lets everything fall apart, and drives all scientists to take jobs abroad before the next uncontrolled pandemic paralyzes the country.
It’ll most likely be avian flu, which is pretty bad. The Trump people are trying to ban MRNA vaccines and cut the vaccine research that might have helped with it.
They found that Callisto’s ionosphere alone cannot explain all existing observations, but that a subsurface ocean in combination with the ionosphere can. Further exploring which scenarios best fit the data, the researchers predicted that the ocean is likely at least tens of kilometers thick, as measured from the top of the liquid ocean to its seafloor, and encased beneath a solid ice shell that itself could range from tens to hundreds of kilometers thick.
Life on Callisto would have a worldview not unlike that of the Krikkiters.
I’m so looking forward to what JUICE uncovers! Europa has been centre stage and is getting its own dedicated mission, but the more we find out about those outer moons, the more fascinating they get. Ganymede is the largest in the solar system and has its own magnetic field. And Callisto being an ocean world? It wouldn’t surprise me if Ganymede is also.
Yeah, shit idea. And exactly why NASA gets shit on for consuming money with less to show for it.
Spend billions on a program set up by one administration, then some tool comes along and wants to cut costs because they want to look effective and cuts NASA’s programs. Program never completes, now it’s just a waste. NASA, being by default a scientific endeavor thar doesn’t need to return an profit other than exportation and research data, is an easy target. Billions invested and nothing to show for it. WhY iS NaSA So iNeFfeCtIve!?! Repeat for another program later.
I do my best to block any news regarding the new administration, so this comes at quite a surprise that it was even considered. Always thought NASA was one of the great prides of the country, but it seems like those days are long gone.
In the mass firing they lake of the people who maintain nuclear weapons and the people working on bird flu. Once they realized they need those people they started trying to rehire them.
