Re: Lost leadership
But what would you rather have, robot probes landing on asteroids and bringing back samples or swimming around the oceans of Jupiters moons - or some crew cut space marine saluting the flag on the moon on live TV

Other countries don't have all their civil servants being political appointees.
If we extrapolate the last few years, in future we are going to have to replace all the police, security services and army chiefs as well as all the government scientists every time the WH changes hands
>Regardless of the merits of any individual case, the fact that a president can simply overrule all due process and pardon anyone is utterly wrong.
Not if used as intended, eg. pardoning all escaped slaves, or more recently all Vietnam draft dodgers (who weren't fortunate sons) seems reasonable
>Getting out of a portion of the gravity well before launching a space vehicle is a viable option
It's no real change in gravity (Earth's surface is 6400km from the center, 30,000ft is only 9km further!)
The alleged advantage is that you can fly out to sea and launch in any direction - it's hard to find a land based launch site that has empty ocean in all directions ! You can also fly to where the weather is nicer, assuming it is good enough to let you get off the ground.
Drawbacks are that you are limited to a small, single payload.
It has to be engineered to support itself sideways while slung underneath an aeroplane and then 'downwards' when the rocket kicks off.
The launch altitude isn't high enough for the rocket to be vacuum optimised, so you still need 2 stages.
And because it has a manned carrier aeroplane you have all the safety costs and restrictions of a manned launch.
The idea is to be able to launch from any latitude in any direction.
For this payload that is probably further north than an equatorial GSO orbit (nobody is putting 20ton communication satellites on this thing).
You want good weather both at the take-off and launch altitude, with a $MM rocket hanging under the wing you don't want to fly through a storm at climb out, even if it is nice at FL300
Mostly it depends on how much swing Boeing/Lockheed still have in Washington, if they can get every US launch on this thing blocked by ITAR.
>This is a way to launch smaller payloads more economically.
TBD - Pegasus never made it economic, although that was under a NASA/military model.
One problem with Cornwall (other than the obvious) is that the whole point of this system is that you can fly to where the weather is nice for a launch - the North Atlantic isn't the most obvious choice.
The other problem is that you can't launch anything American
>SpaceX are avoiding H2 by using methane - basically a compromise between very difficult engineering and performance. It performs better than kerosene, but isn't as hard to engineer for as H2.
It can also be made on Mars, waiting for Mars to have an oil industry makes a kink in their return schedule
Another industry expert's take on ts stratechery intel-problems = Intel need to split into a fab company and a chip design company, but they can't because they are behind on fab technology and their x86 server monopoly is going away
It's not that the Play store isn't open source it's that it imposes a monopoly on where users of the operating system can buy from and so allows the owner to charge monopoly rents - the sort of thing that Microsoft didn't dare to do even before it got DoJ slapped.
It does seem that somebody just wrote the Eu's anti-trust case for them.
>What happens when Huawei retaliates by revoking the licencing of all their 5G patents?
We have Finnish 5G phones that only work in the USA/Eu
We have Indian 5g phones that only work in India
We have official Chinese phones that work in Africa, SE Asia
We have 'hacked' Chinese phones that work everywhere
Next, the internet
