SLS will cost upwards of a billion per launch. Compare that to $90 million for a reusable Falcon Heavy launch or ~$150 million for a disposable one.
- bostik 6y agoKind of off-topic, but trying to watch that video brought this to mind: https://news.ycombinator.com/item?id=22792243 https://news.ycombinator.com/item?id=22792243
- autonoshitbox 6y agoTim can repeat himself often, but he's not bad at what he does. His content is admittedly designed for children.
- navaati 6y agoThat’s a bit harsh, at the beginning of his videos he does a kind of outline of the content. But the content is there ! Kind of understand why you say that when, at one point, he mentions a future video.
- nickik 6y agoAnd SLS Orion Launch: 4x RS-25: 520M 2x SRB: 200M ICPS: 150M (EUS will be more) Core Stage: (not sure) 30M+ given how long they work on it Orion Capsule: 900M That is all without ground infrastructure or people working at NASA. Given that it will probably not launch more then once a year. 100s of M extra. In comparison, a SpaceX Raptor internal cost is 1-2M, Merlin less then 1M. The sale price of the BO BE-4 is 8M.
