About 43% of the energy. But its also worse than that because Mars has a more eccentric orbit and slightly bigger axial tilt. Seasonal variations in solar energy are thus much larger than on Earth (at perihelion you get around 700W/m2,

True, it doesn't amplify, it just focuses. So that's different to the three body problem, in which it wasn't directional as far as I remember.

From a quick search it seems you get invited to these things by filling in a feedback form for Google. As for shadowbanning, well, it doesn't take much to remember Google is a search platform and then to match that with his complaints

Honestly, mostly by writing things people want to read and share. If you aren't doing that you are just wasting people's time or spamming them.

Things in geo orbit aren't perfectly stable, since the Earth's gravitational field is not perfectly uniform. Without active station keeping things tend to gather at two particular longitudes over the equator. So eventually that de

Getting first doesn't mean much if you don't keep up with innovation. Just look at Xerox, Kodak, Nokia, Blackberry... Plenty of companies have had good products but were then outpaced by people who took what they did and made it b

Ok, but almost nobody is going to read an article that requires you to work through 21 lectures, 9 tutorials, and 3 assignments first. It'd be great if they did, and it'd be nice to give the link for interested people, but otherwi

I suspect it's more at a program level. Boeing have lost a lot of money on Starliner, may lose a lot more, and already seem lukewarm on continuing with the project. It's actually NASA that's keener on keeping it running, so t

In the three body problem she uses some property of the Sun's internal layers to amplify the signal. In reality we don't know of any actual property in the Sun that could do this. The gravitational lens idea is different, it makes

Plausibly you can get less cancer by encouraging people to stop smoking, drink less, be less exposured to known carcinogens (either by awareness or regulation). A good healthcare system can also mean you catch cancers early or treat them ea

Is there an actual problem here that airships solve? Is getting cargo across the Pacific one or two days faster (and that's presumably a best case, since airships are heavily weather and wind dependent) actually that valuable? I would

I would guess they still need to learn more about the behaviour during reentry. Relighting the engines or opening the payload door could mean they lose proper attitude control like in the 3rd flight, so they get less info from reentry.

Yep, it didn't really seem convincing until Kepler replaced the circles with ellipses, and even that step took a lot to move past established ideas about the perfection of nature.

Its probably more about the areas that will be affected by the sonic boom. Generally people don't like them happening over populated areas.

You don't need to hit every satellite. You only need to create a lot of debris, and that'll do it for you. Alternatively the radiation from a nuclear blast could take out a big chunk of the network, which is presumably why Russia

The SLS has actually flown since then, so its hard to say it has gotten worse in "EVERY" aspect. I'm not a fan of the SLS or the way NASA is running Artemis, and I can say plenty to criticize the way they work. Believe me, I&

The question seems to me not why there is a speed of causality, but why the speed has this particular number. And it's not clear we know why that is, any more than we know why the proton mass is about 1836 times greater than the electr

Has the cancellation actually affected Starlink in any way? Have they put up satellites more slowly or charged customers more?

You don't need much more than you've listed to operate it, for sure. Especially for a spacecraft that's fairly old and should be behaving in well established ways. Only thing I can think is the Chandra project is funding rese

This guy really didn't like working for NASA, huh? He has some valid points, but they're really smothered by the massive chip he has on his shoulder. Would be a better article if he clearly focused on the points about the SLS.

It shouldn't matter whether you are controlled or not, you still need to show the risk is under 1 in 10,000. If you have a satellite for example, they usually enter uncontrolled and you still need to calculate the risk of killing someo

So, some perspective on whether the FAA will get involved or not. The FAA care about safety. If you have anything falling back to Earth you have to prove it is safe. That usually means you have to do some analysis to show your chance of kil

It's hardly desirable to let rocket debris reenter anywhere - just because China is doing it doesn't mean SpaceX should be free to dump stuff over populated areas. Also, its SpaceX that has proactively grounded their fleet in this

It's much harder at higher frequencies because you need to point your antenna more accurately. That's pretty hard to do by hand on a phone.

French and Spanish colonies actually. Ironic since the French supported the American revolution to stick it to the British.
