> The development of commercial launch systems has substantially reduced the cost of space launch. NASA’s space shuttle had a cost of about $1.5 billion to launch 27,500 kg to Low Earth Orbit (LEO), $54,500/kg. SpaceX’s Falcon 9 now advertises a cost of $62 million to launch 22,800 kg to LEO, $2,720/kg.

Why do you lie?
- travisporter 2y agoEven if true no need to attack a poster
- _yb2s 2y agoIt is required to assume good faith in you HN replies… which imo makes it a nicer place to discuss things. People can be wrong about things or be referring to different information without intentionally lying.
- kulahan 2y agoThis is pretty egregious, but I agree that assuming noble intent is the way to maintain civil discussion. No need to call him a liar - just downvote.
