Don't quote Nyquist, quote Shannon. Nyquist only applies to the minimum sampling rate for an unaliased time domain signal, not directly how much information can be transmitted in that bandwidth. There are plenty of encoding schemes that get multiple bits/baud.

The Tsar Bomba TEST yielded 50MT. That was because it was missing it's outer uranium boost blanket that would've made it dirty as sin but a full 100MT.

I quote:

instrumenation?

... making them hard to detect by the people they're spying on ...

More likely "making them harder to be noticed by the people they're spying on". If I hear a plane constantly buzzing everywhere I go, I'm gonna get suspicious.

The oft-overlooked part of this is all of the infrastructure needed to manage the sats once in orbit. There are only so many earth stations and only so much TDRSS satellite bandwidth available.

Also, by the time a satellite is finished, technology has usually outpaced the onboard systems and made it illogical to duplicate the original sat.

A rifle bullet is 30 to 40 grain ...

That's a little low for anything but a .22 LR bullet. .223/5.56 NATO bullets run 45-70gr, .308/7.62 NATO run 150-220gr. My favorite groundhog round is a .223 diameter bullet massing 52gr at 4000 fps or so.

Wow. I remember reading about BART in my 6th or 7th grade social studies textbook. That was in 1976-77 or so.

Only if you're using air instead of the oxygen you just made when you cracked the water.

and the hoi polloi - how's that?

... but what does it taste like?

No, more like a flounder.

> When the planet's surface is 60% water the meteors are going to hit water 60% of the time.

Not exactly true. There seems to be a relationship between the fall rate and latitude.

Also, the northern hemisphere has proportionally more land than the southern hemisphere (68% vs 32%), you'd expect about twice as many NH impacts on land than in the SH.

You're exactly right - I ordered some JST SM connectors from Element14/Newark for that very reason. #1 they carried the connector and #2 they had the right pins listed *along with a substitute* since the official ones were out of stock.

2500 mAh in 15 mins over USB-C? Just accounting for the charge and assuming 100% efficiency, 2500 mAh in 15 mins is an average current of 10 Amps. That's even optimistic given that the charge profile is usually high current at the start and lower current towards the end. USB-C says it maxes out at 3 Amps.
