Nearly all such satellites would have highly directional antennas, so the aliens would have to be neat earth before they could do that. Voyager is not expecting a command signal from anywhere else but Earth. The signal would have to originate not more than a fraction of a degree from Earth from Voyager's perspective.
They are cancelling flights because those specific airports don't have the equipment to provide a precision landing (ILS) during low visibility weather. They only published a landing procedure with GPS. They will now spend a few months installing the ILS system to enable such landings so they can resume commercial flights.
Before GPS, all airports would be either VFR only or would have an ILS system installed. Since then, some airports were built without an expensive ILS but used a published GPS approach to allow low-vis landings.
They could have continued flights with only VFR navigation, but that would seriously restrict the weather they could operate in.
And now here in California, they are starting "Transitional Kindergarten" or TK for the 4 year olds, before they go to Kindergarten at five. (More focus on reading and writing than a typical Preschool.) TK is offered at the normal public schools, and at most private schools that have K and up.
Prions wouldn't work like that. They would have to be very similar, and the same chirality, as our own proteins, or else the misfold would not self-replicate like prion diseases do.
Not all of them have been peaceful, and it's still private property and they can ask you to leave, with legal consequences if you don't. And a lot of the rhetoric and chants have advocated violence.
Also note that before this switch, years were often designated in relation to the founding of a city or by the start of a ruler's reign. There were always ordinal numbers, so the first year of a reign would be year 1, and there was never a zero, because it was year X of a previous reign.
If enough people are using this new system, Russia could easily pivot to target it as well. Jamming is not inherently hard, especially if a nation is attempting it.
Jamming in the US will bring the FCC down your throat. The stronger the signal, the faster they will show up. Russia transmitting a jamming signal from Russia doesn't have to worry about such things. A jamming device is not hard to find, but on sovereign soil it's still untouchable short of war.
There's no such thing as needing to disconnect while charging, unless you literally leave the battery behind somewhere. If you have two batteries on board, then you can use them in parallel.
Starship, as it is right now, is already a better rocket than SLS. It can already carry more mass and be cheaper (even fully expended) than the SLS's 4 billion cost per launch.
It will get better. Falcon 9 didn't land the first time either, but now it has successfully landed more consecutive times than any other rocket has flown.
There's nothing wrong with saying this is a test. This is only a test, and we don't expect it to be perfect yet. Each time they learn from the data. And SpaceX hasn't repeated the same mistake twice.
In the US model of justice, the judge decides questions of law, and the jury decides questions of fact. This order appears to delegate a law question ("is it constitutional?") to a jury during the trial. If the jury finds the defendant innocent, then double jeopardy prevents any appeal which would change that verdict. Nobody, once declared innocent, can be put on criminal trial again for the same incident.
That's a pretty good description. And most software back then didn't use nice date utilities, they each had their own inline implementation. So sometimes you had to figure out what they were trying to do in the original code, which was usually written by someone who's not there anymore. But other times it was the most mundane doing the same fix you already did in 200 other programs.
It's also the only way that is portable. A professor could evaluate each student, but has no way to transmit that kind of evaluation in a way that schools or employers across the country would trust. They didn't know who the professor is, or what his standards are, or even if he is being bribed to pass somebody. (Which would happen much more if the professors opinion had the weight that the standardized test does. )
It depends where you live. In some areas, channel 3 was a TV station, and channel 4 was blank. The video game worked best when it's not competing against a TV station.
My bank has called me a few times. Each time they ask about specific transactions, so it's mostly yes/no answers. (Occasionally I've asked for additional clarifying info, but they never asked about card numbers or the like.) Usually it's been abnormal transactions that i know about, but a few times it was a cloned card number being used elsewhere, (before chip became standard) and then I had the card shut down.
I'm switching back and forth at will, which is unusual for me with this type of illusion.
