James webb is the perfect example of why we absolutely need NASA and what they do. Did the budget balloon and delays rack up? Yup, and if you read about why you will see that it was basically unavoidable. A private business would have canceled it at the first roadblock (depriving us of an INCREDIBLE scientific tool). And for the actual launch and deployment, the cost of the instrument meant that a very high success r…
JWST is a great achievement. No question about that. But we could have easily made good use of a dozen of them. NASA could have built a dozen with only a small incremental cost, because once you have a design and tooling and test rigs and test plans and machine shop setups, the incremental cost is pretty small. For example, when I worked at Boeing, sinking a die for a forging cost $250,000. Stamping out a forging cos…
there are a huge amount of one time costs associated with the design and engineering of a spacecraft or a satellite that could enable fairly cheap constellations compared to singular satellites, and the testing regimen becomes much more cheap when it’s done as part of a campaign.
I’m a proponent for the disaggregation of satellites from sensors using specified interfaces. Industry is definitely moving in this direction with their satellite buses you can buy fairly cheaply.
Will we want to stick a $3 billion sensor onto a $15 million satellite? I can’t answer that question
