But if the demand is so great wouldn’t it have been easier for them to generate enough launches regardless? The article says the problem was they didn’t have enough to create revenue. If demand is so great they wouldn’t be turning down launches.

AFAIK not with the laser interconnect.

Oh there is demand. Demand for launch services still outpaces supply. Its exploding.

Virgin Orbit was just bad.

> While Virgin Orbit touted a flexible and alternative approach to launch small satellites, the company was unable to reach the rate of launches necessary to generate the revenue it sorely needed.
I mean, even if there were tons of companies clamoring to shoot a satellites into space, how much repeat business would there be? It doesn’t seem like a sustainable income source no matter what. It’s not like the average person on the street is like “I should get one of my own satellites up there.”

Not too long ago, Virgin Orbit was in rarified air among U.S. rocket builders, and executives were in New York celebrating its public stock debut.
The scene was true to the marketing pizazz that has helped Sir Richard Branson build his Virgin empire of companies, showcasing with a rocket model in the middle of Times Square.
The deal, facilitated by a so-called blank check company, gave Virgin Orbit a valuation of nearly $4 billion. But that moment in December 2021 – when the craze surrounding public offerings centered on special purpose acquisition companies, or SPACs, was dying out – previewed the pain to come.
Now, Virgin Orbit is on the brink of bankruptcy. The company on Thursday halted operations and laid off nearly all of its staff. Its stock was trading around 20 cents Friday, leaving it with a market value of about $74 million.

You want a telescope in each hemisphere to get full sky coverage.

ah yes, i had displaced Venera 14 from my head, it also had a microphone and made a short recording. Same thing though: they used a mic.

The physical construction will be by a variety of suppliers, everything from basic excavation and concrete to very fancy optics. It won't be just one company. It also won't start for years, as they haven't even settled where to build it. In the mean time you can work on other telescopes currently under construction.

BTW, the European Southern Observatory (ESO) agency is building a 39.3-metre-diameter telescope at the moment in Chile. The "Extremely Large Telescope". First light is planned for 2028

But 30 meter is not bad either.

It wasn't bad luck that it was cold. It was bad management, communication and decision making regime operating an incredibly complex and dangerous machine. The danger to the o-rings of cold weather was known. While there were numerous factors in the disaster, luck was not a factor.

Starlink still needs ground stations for each connection, no? Besides, are we realistically even looking at that many stations?

Unless the spin rate was so fast that the spiral would be indistinguishable at our distance.

Well... I am not sure what sort of technology we have today, which might be able to keep an astronaut alive there. Considering the longest lived lander lasted only about 2 hours.
However, I would strongly advise against instant teleportation to the surface without any protection.

Because nothing needs to land, less delta V/fuel, and you'd need a lot fewer satellites than stations. Also, there should be little if any new h/w engineering necessary adapting Starlink for lunar operations.

That is just not how the word "history" is used by literally anybody else I can find. In particular, it's not how it's used by historians, who I rather think get to decide what they study.

This leaves out what I suspect is the origin of the trope: Newton assumed spherical celestial bodies of uniform density so he could treat them as point masses.
Whenever I say "assume a spherical {x}", I always make sure to include the second part, in Isaac's honor.

LauncherOne was 500 kg per launch to LEO, for 12 million, with a 2/3 success rate. Just because there is strong demand doesnt mean you dont have to be competitive.
