Zoe Williams is just a deeply, deeply stupid person - whose previous zingers include "democracies don't use nuclear weapons" and "women aren't allowed in mens football because they would win".
Yet when she annoys people with her stupidity, she acts like this is a win somehow?
Her basic thing is revealed in the second paragraph - she considers her ignorant brainfarts to be self evident truths about the universe, and everybody else just a bit silly for not agreeing already. She is utterly incurious as to the actual reasons for going to space.

Secondly, change your location setting in @x to appear in another country - this seems to be a solution for the time being, but possibly will be blocked at some point in the future.
The amount we spend just servicing our debt, not even paying it down, due to previous mismanagement is larger than the amount NASA was spending at the peak of the Apollo program (about 2.5 times current NASA spending)
I know I shouldn't. I know its bait. But you have to engage with critics. Even if its abundantly obvious, from even the thumbnail, that these guys I've never seen before will likely be dishonest idiots.
He's "calling BS" on... oh no, wait, he is selling a book. Maybe I should review it to save others from giving the guy money
"Whose right, the astrophysicist or the billionaires?"
Well guess what. I'm also an astrophysicist, and I think space colonisation is a great idea, so you can stick that appeal to authority where the Sun doesn't shine
I alluded to the NHS experience being shocking, here is what happened. This is "the envy of the world"
My wife has been ill so tried to get a GP appointment. Normal process of phoning at 8:30am and staying on hold for an hour to speak to someone.
She gets through, tells them her symptoms, and they promise a call back. She then heads into work late - I suspect the 8:30 call thing is a way of rationing care in favour of the elderly who don't need to take a morning off.
Finally, late in the afternoon she gets a call back.
They tell her to come in for an in person appointment. She doesn't see a doctor, its a nurse practitioner, who is fairly helpful. Suggests a few things it might be and orders some blood tests, which my wife then gets done (although it takes them several attempts to draw blood)
I’ve been pushing for some time now for the UK to do more in space, including launching payloads from our country. People with a bit of knowledge of the physics of spaceflight object on the basis that the UK is too far north to host a spaceport. This isn’t really true… 🧵
A launch site close to the equator gives you an eastward boost from the earths rotation, and lets you easily access a wide range of inclinations. This is why Kennedy Space Center is in Florida and not Maine, for instance.
But for polar orbits, this doesn’t help you.
If your orbit is close to ninety degrees to the direction of earths rotation, it’s actually a hindrance. From the UK perspective, we also have a lot of sea heading north from our island, so we are in a good place for polar launches.
So after @elonmusk laid out the plan for 5 Starships to Mars in 2026, I went to crunch the numbers. Happily I was already working on this, but now I’ve got a specific number to work with. So 🧵 time…
Here are the three upcoming Mars windows. 2026, 2028/29 and 2031.
Each window presents a chance to go to Mars on a reasonably quick transfer for a delta-v of about 4km/s from Earth orbit. Starship can easily handle this, if it has enough propellant. But because it reaches orbit with its tanks nearly dry, orbital refilling is needed.
There are a number of technical issues to sending a ship to Mars - most of them are not too hard and solvable in the time allotted. The but logistical issue is getting enough tankers though. I have enough information to estimate how many…
