Yes. It’s a viable way to save money if you use a site like https://shucks.top/

Honestly this would make for a neat project — build an esp32 or rp2040 based punchcard reader / printer and then print out all your backup codes (encrypted of course by some hardware based code like a set of dip switches) onto custom punchcard tape.

I didn’t get a chance to look too deep into it, while it looks great for human reading in a terminal, can I just as easily output the diff to a patch file like I do often with ‘git diff [commit] [commit] > patch.txt and git apply it?

Dang, 50% is a lot.

Well, that’s probably true for the most part but by far the reality is that it comes down to lowest bidder 9/10 times. Unrealistic budgets and unrealistic time frames with as cheap labor they can find gets you a large amount of government funded projects throughout all the years.

I would reasonably expect an increase in expected life / flights of a future model for sure but it will be highly dependent on what’s being tested. NASA aren’t making tools, they’re making instruments, if that makes sense. They aren’t producing a rugged tool for accomplishing a mission that someone buys to use, they’re making scientific equipment that carry out experiments and collect specific data. Even the instruments themselves are experiments, such as the durability of joint designs on the collection arms, or the roter materials selected all have a purpose and associated datapoint.

All that to say, the expected lifespan / flights on the next model will reflect the mission goals and budget / cost of the project and not necessarily an accurate expectation of the system. More or less “we designed this instrument to deliver x amount of data” not “we designed this tool to survive y number of uses”.

There’s some truth to underestimating the equipment for PR, it certainly has a huge positive PR spin to last 3 years off 5 flights estimate. But at the same time they are spending a lot of their budgets on projects that need to collect data. If 5 flights gives them the guarantee of solid data, then it was a justified project. On the other side of this, it was the first powered flight in any atmosphere outside of earth. There’s no way we had enough data to know just how long or how many flights it would do. Being this far off is reasonable. Same for the previous rovers, their estimates were low and far exceeded. The rover this time around got a much longer estimate, even if it’s beaten it already.
