This article is pure propaganda, written to help justify to the American public the ludicrous pork-barrel spending that the SLS program really is. It&#x27;s a &quot;feel good&quot; article designed to make your <i>feel good</i> about your taxpayer dollars being set on fire.<p>It is chock full of emotional words and phrases to put you in the right frame of mind: &quot;electric&quot;, &quot;very emotional&quot;, &quot;gratifying&quot;, &quot;exciting&quot;, &quot;love them all&quot;, &quot;amazing&quot;, etc...<p>You know what&#x27;s amazing? The real story, buried down in paragraph #35:<p><i>&quot;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.&quot;</i><p>For reference, $146M -- per engine -- is three times what it costs to launch a payload to space on the Falcon 9. And there&#x27;s FOUR of those engines burnt up to launch the SLS each time.<p>It&#x27;s not electric, or gratifying, or exciting. It&#x27;s madness.
