Happy to see competition, but I don't see how anyone can beat SpaceX, with brilliant engineers and their own rockets which are the lowest cost in the industry. If Starship is successful it's game-over for lowest cost space launch. Similar to Tesla, where no one can match their ...
Major progress occurred in the mid-20th century when NASA used hydrogen as a fuel source for space rockets. In the modern industrial revolution era, the main focus is on using hydrogen as fuel, especially in fuel cells, to produce electricity. The widespread adoption of hydrogen is due to ...
The media went ga-ga last week over the final flight of the Space Shuttle program. They talked about the past successes of NASA. They insisted the that fact American astronauts will have to hitch expensive rides on Russian rockets to get to or from the International Space Station for the ne...
