The Space Shuttle Engines Will Rise Again – RS-25 Engine History
- jiggawatts 5y agoThis article is pure propaganda, written to help justify to the American public the ludicrous pork-barrel spending that the SLS program really is. It's a "feel good" article designed to make your feel good about your taxpayer dollars being set on fire. It is chock full of emotional words and phrases to put you in the right frame of mind: "electric", "very emotional", "gratifying", "exciting", "love them all", "amazing", etc... You know what's amazing? The real story, buried down in paragraph #35: "NASA doubled down on the RS-25 in May 2020 when it awarded Aerojet Rocketdyne a $1.79 billion contract to produce 18 more RS-25 engines, on top of the six already on order. The combined price between this new RS-25 contract and the earlier one—resulting in a $146 million tab for each single-use SLS engine—has raised critical eyebrows." For reference, $146M -- per engine -- is three times what it costs to launch a payload to space on the Falcon 9. And there's FOUR of those engines burnt up to launch the SLS each time. It's not electric, or gratifying, or exciting. It's madness.
