NASA desperately needs more options. They shouldn't need to expend an SLS to launch an uncrewed Orion with a test heatshield on a trajectory equivalent to a moon return. They should be able to launch that on top of a Falcon Heavy. A Falcon Heavy can launch 63 tons to LEO and a fueled Orion plus service module weights slightly north of 20 tons. An Orion mass simulator with enough attitude control mated with a FH second stage would leave a lot of delta-v to accelerate the capsule back into the atmosphere.
SpaceX is the only major operator of spaceflights in the US: more than 95% of all satellites launched are launched by SpaceX, not just in the US, but worldwide.
We have regions where we deliberately minimize light pollution, but those regions aren't immune to Elon's swarm of photobombing satellites.
Not that I don't think it's cool to have a web of spacecraft enveloping the planet and bringing high-speed communications to everyone everywhere - it's pretty impressive to point up and show a train of satellites to a kid - but astronomers have been complaining about them and they are right.
This is about going to the moon. Space-x is over budget and extremely late. It has nothing to do with the management there, only that it is better to come up with a solution without them.
I only suggested a Falcon Heavy because the rocket exists, is flight proven, and has enough capacity to shoot an Orion to any trajectory it is expected to encounter.
Imagine if NASA had the resources and the freedom to pursue a high-risk high-return strategy the same way SpaceX did. NASA can't afford high-profile failures because it needs political support to function from a Congress that doesn't understand engineering.
Now imagine the public good will if the US could have built a network of LEO satellites providing communications to everyone on Earth regardless of nationality, with equal access and funded by governments so that all their residents could have access to it for free (once they buy an antenna made in the US).
Some will say it'd be communism. I would say it could be part of a Pax Americana that doesn't involve coups, but is based on willing cooperation.
Cream is a very distinctive font. It’s perfect for Smalltalk. In the 1980s I remade it for the Apple II to be used in a game. Obviously very little text would fit on the screen it was used for.
I heard something like that about the Concorde at the Air and Space Museum. What killed it was not fuel costs, but cheaper long-distance phone calls and fax machines.
But if a country takes the Chinese approach and pushed inexpensive rail as a way to open new economic opportunities, the idea of flying as your daily commute moves from ridiculous to feasible (if you replace the airplane with a train).
The thing that killed the Concorde was a fatal crash that killed everyone on board.
The thing was already losing money because it guzzled fuel and was horribly loud and uncomfortable inside, while still costing a fortune for tickets. Not many people really wanted to pay 1st-class fares for worse-than-economy comfort just to shave a couple hours off the flight. Also, the plane could only operate at supersonic speeds over the ocean, so when it flew to/from Texas, it had to operate at subsonic speeds (and guzzle even more fuel because it was inefficient at those speeds), and the average trip time wasn't that much faster than a regular jumbo jet. It had been going downhill for a while, but that fatal crash was the end; they stopped all operations after that.
Sure, better communications might have contributed to its downfall, but that would have affected all air travel; just comparing like-for-like, the Concorde really wasn't a great alternative to the subsonic jumbo jets which became more and more prevalent for transcontinental routes.
No, it was definitely the cost to operate it and the sonic boom associated with flying at that speed. The company operating the Concorde never made a profit.
Clojure is a beautiful Lisp, and coupled with the JVM it's extremely powerful.
