My wife has a fish allergy. But it’s not all fish, because she’s fine with canned tuna and can still enjoy shrimp. But we wish we could narrow it down somehow. She would love a nice fish dinner, or even a Fillet-o-fish someday if we could find out what’s safe.

Insurance “fraud” would require that the initial accident was on purpose, staged, or otherwise fake. Part of the purpose of insurance is to cover you when you are sued. (as long is it’s related to something you are covered for.)

The ISS gets cargo deliveries from a Russian unmanned spacecraft called “Progress” and also from the SpaceX Cargo Dragon. (There have also been cargo deliveries from Cygnus and the Japanese H-II modules.)

One more note:

You don’t want to put the authenticator codes in the same database as your password manager, or else that will become a single point of failure if somebody can get the master password.

The rocket itself is only 1 ton when empty. But that line does give them plenty of margin for dynamic shock loads.

We have both wandered far from the original topic, but the relevant part of the point I was trying to make is we have reduced the mass of support hardware, such as the computer that guides the rocket, which enables a larger payload (people and their luggage) to reach orbit if all else is equal.

The value of the shrinking electronics is that much smaller 10-pound satellites do the same job, or even more, than older 2000-pound satellites. That means a smaller rocket, such as Electron can put more capability into orbit in one launch than we did in 10 launches during the 70's. (Capability here can mean radio or…

Things they learn by reusing Electron might also apply to Neutron, so there might be a chance to influence the design. Maybe not in how they catch it, but in how the engines are designed, and what work is needed to get them ready again.

Electron is a much smaller rocket than Falcon 9. It weighs less than a ton when empty.

One important measure for a rocket engine is ISP, which is kind of like MPG in a car. The Saturn V main engine “F-5" had an ISP of 304. RocketLab’s Rutherford gets 343. SpaceX has the Merlin with 311 and the Raptor at 363. So yes, modern rockets do get better energy per mass of fuel than Saturn V. But the Space…

How would that work on an arm, which must go though large temperature swings just by wearing or removing a jacket.

They have had a few water landings by parachute. But this will be their first attempt at a mid-air catch. Avoiding saltwater will probably simplify the refurbishment for a next flight.

It’s easier to fit multiple sensors in a mannequin that will collect much more detailed data than if a mouse lives or dies. It’s also important to measure how much of the radiation penetrates multiple inches of body mass, which is not something you can get from a small mouse.

When somebody has “all the X in the world” then it would really have no value. The value comes from trading with others.

They keep saying Proof of Stake is just around the corner, which will vastly reduce the energy needs. But it’s not here yet.

Agreed that it’s a two-way street. I just think a connected world is overall more safe than two or three separate world systems competing for space. We don’t need a new Iron Curtain for them to hide behind.

There is some satisfaction in just cutting them off. But as long as they are connected, we have influence which can moderate their worst impulses. As long as their economy is intertwined with ours, they are less likely to do something as stupid as Russia is doing. (note that it’s only less likely, not impossible.)

In my app, it shows two options: “Not Interested” (what you are talking about) and “Don’t recommend channel.” The second option is much more effective, as long as you want to never see anything from that channel. (Not as useful if you do like channel “X” but have already seen episode 34 and don’t need to see it again.)
